Asset Tags for Equipment & Device Tracking

Schools, government agencies, and healthcare organizations all have to keep track of the computers and equipment they own — Chromebooks, tablets, laptops, and everything else issued to staff or students — and for many of them, that's not just good practice, it's a real accounting or compliance requirement.

General information, not legal advice — confirm current requirements with your compliance officer or auditor.

Asset ID Labels

Intertronix's Custom Asset Identification Labels & Durable Asset Tags give every device a permanent, easy-to-scan ID, so your team can log what you own, where it is, and who's responsible for it — including Chromebook carts, tablets, and other devices that move between classrooms or staff. Serialized numbering, barcodes, and tamper-evident options are available, and stock sizes ship without artwork approval.

Why it matters

Government entities, including school districts, generally follow accounting standards (GASB Statement No. 34) that require them to track and report the value of equipment and other capital assets on their books. Healthcare organizations have their own rule: HIPAA's Security Rule (45 CFR 164.310(d)) requires tracking hardware and electronic media that could hold patient information, including a record of who's responsible for each device. In both cases, an accurate inventory starts with being able to identify each piece of equipment — which is exactly what an asset tag is for.

Cannabis & CBD Label Compliance: California and Colorado

Cannabis and CBD products sold at retail are subject to state-specific packaging and labeling rules. Tamper-evident labeling is one piece of that picture — this guide explains what California and Colorado currently require, and where Intertronix's tamper-evident labels and seals fit in.

This page is general information, not legal advice. Requirements change and vary by license type and product category — always confirm current rules with your state's cannabis regulatory agency or your compliance counsel before packaging product for sale.

California

California's Department of Cannabis Control (DCC) requires cannabis goods to use tamper-evident packaging — packaging that lets a consumer visually tell if it's been opened before. Recognized methods include a plastic seal, a sticker across the lid or opening that tears when removed, or a lid designed to pop up once broken. Child-resistant packaging is a related but separate requirement, and it applies to the container itself (certified child-resistant packaging, specific bottle caps, or heat-sealed plastic at least 4 mils thick) — a tamper-evident label does not by itself make a container child-resistant. Licensees are responsible for verifying their full packaging meets DCC standards before product reaches a retail shelf.

Colorado

Colorado's marijuana regulations (1 CCR 212-3) require regulated marijuana product to be in a child-resistant container by the time it's transferred to a retail or medical marijuana store. The rules also recognize tamper-evident "Marketing Layers" — sealed outer packaging that lets a receiving store confirm a product hasn't been opened without breaking that seal, which is where a tamper-evident label is typically applied in the supply chain.

Where tamper-evident labels fit

Intertronix's CBD and Marijuana Labels — including tamper-evident seals, VOID stickers, and exit bags — are designed to provide the visible tamper indication that states like California and Colorado call for. They're one part of a compliant package, alongside a child-resistant container that meets your state's specific standard. If you're not sure which combination fits your license type, our team can help you find the right label — final compliance sign-off is always your call and your regulator's.

Tamper Evident Labels & Security Seals Glossary

Clear definitions for the materials, mechanisms, and terminology used across the tamper evident label and security seal industry. Use this glossary to understand the difference between label types, substrates, and security features before choosing a solution for your application.

Anti-Counterfeiting

The use of security features such as holograms, serialized labels, and tamper evident seals to make it difficult or commercially unviable to replicate or fraudulently reproduce a product, package, or document.

Asset Identification Label

A durable label used to permanently mark equipment, tools, or inventory with a unique identifier, often combined with tamper evidence and a barcode or serial number for tracking purposes.

Barcode (Code 128)

A high-density 1D (linear) barcode format capable of encoding letters, numbers, and symbols. Commonly used on security labels for inventory tracking, asset management, and sequential serialization.

Barcode (Data Matrix)

A 2D barcode format that stores data in a small square or rectangular grid of dots. Data Matrix codes can hold more information than 1D barcodes in a smaller footprint, making them useful on compact security labels.

Barcode (QR Code)

A 2D barcode format readable by smartphone cameras, often used on labels to link to product authentication pages, warranty registration, or verification portals.

Brand Protection

Strategies and physical security features - including holographic labels, serialization, and tamper evident seals - used by manufacturers to prevent counterfeiting, gray market diversion, and unauthorized reproduction of branded products.

Calibration Seal

A tamper evident label applied to equipment such as fuel pumps, scales, or meters after calibration, providing visible proof if the equipment has been accessed or adjusted since the last inspection.

Chain of Custody

A documented and verifiable record of who has handled or had access to an item, often supported physically by tamper evident or serialized seals that show whether a container or package has been opened between custody transfers.

Custom Print

Labels manufactured with buyer-specified artwork, logos, text, colors, or serialization, as opposed to blank or generic stock labels.

Delaminating Label

A tamper evident label that separates into visibly distinct layers when removal is attempted, permanently exposing a warning pattern or message. Intertronix's TamperFlex® line uses delaminating construction.

Demetalization (Laser Demetalized)

A manufacturing process that uses a laser to selectively remove a thin metallic layer from a label's surface, creating custom text, logos, or patterns with high precision. Laser demetalized labels are difficult to replicate, making them useful for authentication and brand protection.

Destructible Label

A label made from brittle, ultra-thin vinyl that physically shatters into small fragments when removal is attempted, making it impossible to lift the label intact and reapply it to another item.

Frangible Film

A thin, brittle plastic film engineered to break apart or fracture into small pieces under stress, rather than stretching or peeling cleanly. Frangible films are the base material used in destructible security labels.

Hologram (Security Hologram)

An optical security feature that displays a three-dimensional or iridescent image when tilted under light. Security holograms are embossed or laser-etched onto labels to provide visual authentication that is difficult to counterfeit with standard printing.

Jewelry Security Tag

A small tamper evident tag, often loop-style or adhesive-backed, designed for attaching to rings, watches, eyewear, and other high-value retail items without damaging delicate finishes, used for loss prevention and price/SKU tracking.

Metallic Void Label

The most common type of tamper evident label, constructed with a thin metallized layer over an adhesive base. When peeled, the label splits between layers, permanently revealing a hidden VOID message on both the surface and the removed label.

Non-Residue Label

A tamper evident label designed to show clear evidence of removal on the label itself, while lifting cleanly from the applied surface without leaving adhesive residue behind. Used when surface cleanliness after removal is required, such as returnable packaging.

Oriented Polypropylene (OPP)

A plastic film substrate stretched during manufacturing to increase strength and clarity in one or more directions. OPP is used as a base material for certain label types requiring durability and a smooth print surface.

Pressure-Sensitive Adhesive (PSA)

An adhesive that forms a bond when pressure is applied, without requiring heat, water, or solvent activation. Most tamper evident labels use pressure-sensitive adhesives engineered to bond aggressively enough that removal triggers the label's tamper-evident mechanism.

Sequential Serialization

The practice of printing a unique, incrementing number or code on each label in a production run, allowing individual units to be tracked, authenticated, or tied to specific orders, batches, or customers.

Substrate

The base material a label is printed and constructed on, before adhesive and any additional layers are applied. Common substrates for security labels include polyester (durable, chemical- and moisture-resistant) and vinyl (flexible, cost-effective, suited to curved surfaces).

Tamper Evident

A property of a label or seal that causes it to visibly and permanently change - through a VOID message, pattern break, color shift, or physical fragmentation - when removal or tampering is attempted, without necessarily preventing removal itself.

Tamper Proof (Tamper Resistant)

A property of a label, seal, or mechanism designed to physically resist or prevent removal or access entirely, rather than simply showing evidence after the fact. True tamper-proofing is difficult to achieve with adhesive labels alone, which is why most security applications use tamper evident rather than tamper proof solutions.

VOID Pattern

A repeating word, message (typically "VOID"), or graphic pattern printed on the underside of a tamper evident label's face layer, which becomes visible on the surface and/or the removed label once the label is peeled or disturbed.

Void Sticker

A common term for a tamper evident label engineered to reveal a hidden VOID message when peeled, using a multi-layer adhesive construction that separates on removal, leaving permanent evidence on both the surface and the label itself.

Warranty Seal

A tamper evident label placed over a seam, screw, or access panel on a product to void the manufacturer's warranty and indicate unauthorized disassembly if the seal is broken or removed.

Security Tape

Tamper evident adhesive tape used to seal boxes, cartons, and shipping containers, which leaves a visible "VOID" or "OPENED" message on the surface beneath if cut or peeled, providing evidence of tampering during transit.

Holographic Security Labels & Brand Protection

Fake versions of real products are a bigger problem than most brands realize — and counterfeiting is against the law, not just bad for business. A good security label makes it easy for customers, retailers, and investigators to tell your real product from a knockoff.

General information, not legal advice — talk to a trademark attorney about protecting your specific brand.

Holographic Security Labels

Intertronix's Holographic Security Labels and Custom Security Labels use holograms, serial numbers, and other details that are hard to copy, so people can check at a glance whether a product is genuine. Stock and custom designs are available, including serial numbers for tracking.

Why it matters

Selling fake products under someone else's brand is a federal crime, with serious penalties for the people doing it. A security label won't stop counterfeiters on its own, but it gives your customers and retailers an easy way to spot a fake, and it gives you something concrete to point to if counterfeit product does show up.

Sources: 18 U.S.C. § 2320 (Trafficking in Counterfeit Goods or Services)

Holographic Security Seals for Authentication & Warranty Protection

A tamper-evident seal only protects a warranty or a piece of equipment if the seal itself can't be faked. A plain paper VOID sticker can be photographed and reprinted — a hologram is much harder to reproduce convincingly, which is why holographic seals are used anywhere both tampering and counterfeit replacement of the seal itself are a concern.

HoloStrip® Holographic Security Labels

Intertronix's HoloStrip Holographic Security Labels combine a holographic strip with built-in security slits, so any attempt to remove the seal tears it apart rather than lifting cleanly. The complex, multi-layer geometric holographic pattern is difficult to reproduce, which helps a genuine seal stand out from a counterfeit one. Custom printing supports logos, sequential serial numbers, barcodes, and QR codes, so each seal can be tied to a specific unit, service record, or warranty. Available in two sizes (1.3"x0.7" and 2"x1") in quantities from 250 to 10,000.

Why it matters

A hologram isn't just there to show that a seal was removed — its complexity is also what makes the seal itself hard to fake. That matters anywhere a security or warranty seal could be a target for both tampering and forgery: someone attempting an unauthorized repair, part swap, or access could try to hide it by replacing the seal with a plain reprint, but a multi-layer holographic pattern with serialization is far harder to reproduce convincingly. Pairing a hard-to-copy seal with a unique serial number, barcode, or QR code also lets a manufacturer or service center check a seal against records, not just check that it's intact.

Liquid Contact Indicators for Warranty and Shipping Damage Claims

Water damage is one of the most disputed reasons a warranty or damage claim gets denied — a product that failed on its own, spoiled in transit, or arrived compromised can look identical to one that was exposed to liquid along the way. Liquid contact indicators are how manufacturers and shippers close that gap: a small label that changes color permanently on contact with liquid, so there's a visible record either way.

Tamper H2O® Water Indicating Labels

Intertronix's Water Indicating Labels are white until they contact water or a liquid containing water, then turn a permanent red. They're built to resist high humidity, so the color change reflects actual liquid contact — a spill, submersion, or condensation that has formed into standing moisture against the label — rather than ambient moisture in the air. They also resist UV light and common chemicals, and ship in a printable format for branding or tracking. Available in quantities from 250 to 10,000 for electronics, pharmaceuticals, food and beverage, medical devices, and logistics/shipping applications.

Why it matters

Liquid contact indicators are a standard tool across many product categories for warranty and damage-claim determination: once activated, an indicator gives a technician, claims handler, or receiving inspector a quick, visible way to check whether liquid exposure — not a manufacturing defect or mishandling elsewhere in the supply chain — caused a failure or spoilage. Because a compromised indicator could otherwise be swapped out unnoticed, many manufacturers add tamper-resistant details to the indicator itself.

Tamper-Evident Area Seals for Restricted Doors & Equipment Rooms

Hotels, restaurants, and other hospitality properties have plenty of doors that are supposed to stay closed between inspections or service calls — electrical panels, mechanical rooms, pool equipment closets, storage areas. When a door like that is sealed, anyone can tell at a glance whether it's been opened since the last check.

General information, not legal advice — confirm current requirements with your facilities, safety, or compliance team.

Area Seals

Intertronix's TamperGuard® area seal labels apply across a door, panel, or access point and leave a clear void or torn mark if someone opens it, so staff or an inspector can tell at a glance whether it's been disturbed since it was last checked. Available in multiple sizes and colors, in stock quantities from 250 to 10,000.

Why it matters

OSHA's lockout/tagout standard (29 CFR 1910.147) is the best-known federal example of this idea: any employer servicing equipment with hazardous energy has to keep the isolating device untouched, and the tags used for that have to be non-reusable and non-releasable once attached (29 CFR 1910.147(c)(5)(ii)(C)(2)) — tamper-evident by design. The same logic applies more broadly to any restricted door or panel a hospitality property needs to keep closed: a torn or missing seal is the tell that something changed.

Sources: OSHA 29 CFR 1910.147(c)(5)(ii)(C)(2)

Tamper-Evident Calibration Seals for Test & Measurement Equipment

Gauges, meters, and scales that are periodically calibrated need a way to show whether they've been opened or adjusted since that last calibration. A tamper-evident calibration seal placed over an access panel or adjustment screw gives an immediate, visible signal if the instrument has been tampered with — protecting both the accuracy of the reading and the record of when it was last verified.

TamperColor® Security Color Labels

Intertronix's TamperColor® Security Color Labels are available in over 10 colors, making them well suited to calibration programs that use color-coding to track inspection intervals, departments, or equipment lines at a glance. Like all Intertronix tamper-evident labels, TamperColor reveals a permanent VOID pattern on both the label and the surface beneath if removal is attempted. Labels are available blank or custom printed with sequential serial numbers, logos, and 1D/2D barcodes for integration with calibration tracking systems, in sizes from 0.5" diameter up to 2.75" x 1", starting at quantities of 250.

Why It Matters

Once a calibration seal is broken, it can't be pressed back into place or reprinted to look untouched — the VOID pattern is permanent on both the label and the surface underneath. That makes it a reliable way to confirm an instrument hasn't been opened or adjusted since it was last calibrated, without needing to check a separate log. Assigning a color to a calibration date or interval adds a second layer: technicians can spot an overdue or tampered instrument visually, at a glance.

Not sure which color or size fits your equipment? Request a free sample pack and test it on your own surface before placing a production order.

Tamper-Evident Electoral Labels for Ballot Drop Boxes

Ballot drop boxes sit unattended between pickups, so election officials need more than a lock — they need a way to tell whether anyone got past it. Federal election security guidance recommends sealing every drop box with a tamper-evident seal in addition to its lock, and logging that seal's number each time the box is opened and re-sealed.

TamperGuard® Non-Residue Electoral Labels

Intertronix's TamperGuard® Non-Residue Security Labels are built for exactly this kind of chain-of-custody use: attempting to peel one triggers a permanent VOID pattern across the label itself, so it can't be pressed back down and resealed, while the label lifts cleanly without leaving adhesive residue on the box. As electoral labels, custom printing supports company logos, sequential serial numbers, and 1D/2D barcodes or QR codes, so each drop box's seal can carry a scannable ID and be logged and matched against a chain-of-custody record. They're also available in 10+ colors for agencies that want their seals to match existing signage or color-code by location, in quantity tiers from 250 to 10,000.

Why it matters

Guidance from CISA's Elections Infrastructure Government Coordinating Council recommends that, "in addition to locks, all drop boxes should be sealed with one or more tamper evident seals," and calls for election staff to record the security seal number both when a box is opened and again when it's locked and re-sealed. Uniquely numbered, scannable electoral labels are what make that chain-of-custody record possible.

Tamper-Evident Labels for OTC Drugs & Cosmetics

Unlike general food packaging, tamper-evident packaging for over-the-counter drugs — and a narrower set of cosmetics — is a specific federal requirement, not just good practice.

General information, not legal advice — confirm current requirements with FDA guidance or your compliance counsel.

Tamper Evident Labels

Intertronix's Tamper Evident Labels, Void Stickers & Security Seals are used by pharmaceutical companies and pharmacies to seal bottles, cartons, and caps so any opening leaves visible, permanent evidence. No artwork approval required on stock items, and custom sizes/printing are available for regulated packaging runs.

Why it matters

FDA requires OTC drug packaging to carry a visible tamper-evident indicator or barrier (21 CFR 211.132), with a few exemptions (dermatologics, dentifrices, insulin, lozenges) — and the package must say what the tamper-evident feature is. Cosmetics carry a narrower version of the same rule: it applies specifically to liquid oral hygiene products and vaginal products (21 CFR 700.25), not cosmetics generally.

Not sure if your product falls under either rule? Our team can help you find the right seal — the compliance determination is always yours and your regulator's.

Tamper-Evident Labels for Payment Terminals & POS Devices

Retailers and other businesses that accept card payments have to periodically inspect their card readers and payment terminals for signs of tampering or unauthorized swapping — it's one of the standard security requirements built into the rules that govern how card payments are handled.

General information, not legal advice — confirm current requirements with your acquiring bank, payment processor, or Qualified Security Assessor (QSA).

Terminal Security Labels

Intertronix's tamper-evident labels apply over a device's seams, screws, or access panels, so any attempt to open a card reader or swap it out leaves a torn or "VOID" mark behind. Sequential numbering options make it easy to log and verify that a specific device hasn't been touched since it was last checked.

Why it matters

The Payment Card Industry Data Security Standard (PCI DSS) requires businesses that handle card payments to periodically inspect point-of-interaction devices — payment terminals, PIN pads, and card readers — to detect tampering and unauthorized substitution (Requirement 9.5.1.2). Guidance on that inspection specifically calls out checking for missing or altered security labels as one of the signs of a compromised device. A tamper-evident seal gives staff something concrete to check at each inspection.

Sources: PCI DSS v4.0.1, Requirement 9.5.1.2

Tamper-Evident Seals for Dietary Supplements

Dietary supplements aren't held to the same tamper-evident rule as OTC drugs — but FDA still requires packaging that protects the product, and a tamper seal is the simplest way to prove it wasn't opened before it reached the customer.

General information, not legal advice — confirm current requirements with FDA guidance or your compliance team.

Tamper Evident Labels

Intertronix's Tamper Evident Labels, VOID Stickers & Security Seals close bottles, jars, and pouches so any opening is immediately visible. They're a stock item, no artwork approval needed, and ship in bulk for supplement brands and co-packers.

Why it matters

FDA's manufacturing rules for dietary supplements (21 CFR 111.70 and 111.410) require packaging that protects the product and matches quality specifications, but they don't spell out a tamper-evident feature the way the rule for OTC drugs does. Most supplement brands add one anyway — it's treated as standard industry practice, and it's one of the easiest ways to reassure a customer that a bottle wasn't opened before it got to them.

Tamper-Evident Seals for Food & Beverage Packaging

Food and beverage packaging isn't held to the same tamper-evident mandate as OTC drugs or cosmetics — but a tamper-evident seal is still one of the simplest ways to show a customer their order wasn't opened in transit, and it's required outright in some cases.

General information, not legal advice — confirm current requirements with your state or local health department.

Food Tamper Seals

Intertronix's Food Tamper Seals are narrow tear-strip labels built to close bags, containers, and lids so any opening is immediately visible — torn or broken the moment someone tries to get in. They're a stock item, no artwork approval needed, and ship in bulk quantities for restaurants, delivery kitchens, caterers, and food producers.

Why they matter

FDA requires tamper-evident packaging by regulation for OTC drugs and cosmetics; general packaged food doesn't carry that same federal mandate, though tamper-evident sealing is recognized as good practice under FDA's food defense guidance. California goes further: AB-3336 requires restaurants to seal ready-to-eat food with a tamper-evident method before handing it to a third-party delivery driver, effective since 2021.

Not sure what your state or platform requires? Our team can help you pick the right seal — final compliance is always your call and your regulator's.

Tamper-Evident Seals for Gas Pumps, Utility Meters & Calibrated Equipment

Gas pumps, utility meters, and other equipment regulated under state weights-and-measures laws all have to be sealed after calibration or inspection, so it's obvious if someone tampers with them afterward. That requirement traces back to a national model standard used by regulators across the country.

General information, not legal advice — confirm current requirements with your state weights and measures office or calibration authority.

Calibration & Meter Seals

Intertronix's Secure.It sequentially numbered stickers are built for exactly this: tamper-evident labels with permanent adhesive and consecutive serial numbers you can log at the time of calibration, so a missing or broken seal is an immediate flag that a device may have been opened since. Available in multiple colors and stock quantities, ready to ship without artwork approval.

Why it matters

NIST Handbook 44 — the model weights-and-measures code adopted in whole or in part by all 50 states — requires that any weighing or measuring device with an adjustable component be built with a way to apply a security seal that must be broken before that adjustment can be made (General Code, Section G-S.8). Once a device passes calibration or inspection, an intact, sequentially numbered seal is what lets an inspector or operator confirm it hasn't been touched since.

Sources: NIST Handbook 44, General Code §G-S.8

Tamper-Evident Seals for Medical Device Packaging

A device that arrives in an altered or opened package isn't just bad for business — FDA rules say packaging has to protect against that from the moment it leaves the manufacturer.

General information, not legal advice — confirm current requirements with your quality team or regulatory counsel.

Tamper Evident Labels

Intertronix's Tamper Evident Labels, VOID Stickers & Security Seals seal device packaging, kits, and shipping containers so any opening or alteration is easy to spot before a device reaches the user. No artwork approval needed on stock items, and custom sizes are available for regulated packaging runs.

Why it matters

FDA's Quality System Regulation (21 CFR 820.130) requires device packaging and shipping containers to protect against alteration or damage during normal shipping, storage, and handling. For sterile devices, packaging also has to meet ISO 11607, the standard for keeping the sterile barrier intact until the device is opened for use. Neither one names a specific sticker or seal — but a tamper-evident label is a simple way to show that barrier wasn't broken before it got to the user.

Sources: FDA 21 CFR 820.130 · ISO 11607-1

Tamper-Evident Tags for Jewelry Returns

A ring or necklace that's been worn isn't the same item a jeweler sold — but once a tag comes off, there's often no way to tell whether a "like new" return was actually worn. A tamper-evident tag closes that gap.

Jewelry Security Tags

Intertronix's Custom Jewelry Security Tags attach securely to a ring, chain, or other piece and can't be reattached once removed, so a returned item still wearing its tag is one a customer never actually took off the counter. Custom printing and quantity tiers from 250 to 10,000 are available, ready to ship without artwork approval.

Why it matters

Return fraud costs retailers billions of dollars a year, and "wardrobing" — buying an item, wearing or using it, then returning it for a refund — is one of the practices the National Retail Federation specifically tracks in its annual returns research. For jewelry, a worn piece often can't be resold as new, which is why many jewelers condition returns on the security tag still being attached: no tag, no return.

Sources: National Retail Federation, 2025 Retail Returns Landscape

Tamper-Evident Tape for Secure Shipping & Packaging

A package that arrives looking untouched isn't the same as one that arrived unopened. Whether it's a box of electronics, a shipment of jewelry or other valuables, or anything else that needs to reach its destination with proof it wasn't opened along the way, tamper-evident tape gives everyone downstream a simple way to check.

Security Tape (Tamper-Evident Tape)

Intertronix's Security Tape ships as a stock item in 2" wide rolls — 55 or 110 yards, in red or blue — so it can be cut to whatever length a package needs, from a small parcel to a full pallet. Any attempt to peel it back reveals a visible VOID pattern that can't be hidden or smoothed over. For larger-volume orders, custom printing is also available — logos, company or agency names, warning text, or other markings.

Why it matters

Organizations that handle sensitive or high-value shipments use tamper-evident tape as a simple, visible safeguard: a broken or void-marked seal on arrival is immediate proof that a package was opened somewhere in transit. The FBI Laboratory, for example, recommends sealing evidence containers with "tamper-evident or filament tape" in its own guidance for evidence handling — the same underlying idea that applies to electronics, jewelry, pharmaceuticals, and any other shipment where knowing a package arrived unopened matters.

VOID Stickers & Warranty Seals: What You Can (and Can't) Do

A broken VOID sticker is good proof that someone opened a product — but by law, it can't be the only reason you deny a warranty claim.

General information, not legal advice — check your own warranty terms with a lawyer.

VOID Stickers & Warranty Seals

Intertronix's VOID Stickers, Tamper Evident Labels & Security Seals tear or leave a visible "VOID" mark the moment a case, cover, or bottle is opened. That makes them a simple way to catch unauthorized tampering, cut down on warranty fraud, and give your service team a clear record of what happened. Stock and custom sizes ship without artwork approval.

Why it matters

Federal law (the Magnuson-Moss Warranty Act) says a company can't require customers to use one specific brand of part or repair service just to keep their warranty valid, unless that part or service is free. The FTC has warned manufacturers more than once that slapping a "warranty void if removed" sticker on a product isn't enough on its own to deny a claim — doing that can be treated as misleading customers.

You can still use a tamper seal. It just can't be your only reason for turning down a claim. It works best paired with warranty wording that says what the seal actually does — flags that something was opened, rather than automatically canceling coverage.
