Tamper-Evident Packaging for Supplements: What FDA Actually Requires (and Doesn't)

The rule most people assume exists doesn't, not for supplements

Over-the-counter drugs carry a specific federal tamper-evident packaging mandate under 21 CFR 211.132. Dietary supplements do not have an equivalent, specific tamper-evidence regulation. Supplements are instead governed by 21 CFR Part 111, FDA's current good manufacturing practice rule for supplements, which requires quality control processes and packaging that protects the product's identity, purity, strength, and composition, but doesn't specify a tamper-evident seal, band, or induction liner the way the OTC drug rule does.

Why brands build it in anyway

Major retailers, Target, Walmart, most national chains, require tamper-evident packaging as a vendor condition regardless of what federal law technically mandates for the product category, because retailers carry their own liability exposure and consumer trust considerations independent of FDA's minimum requirements. In practice, this means the retail floor requirement is often stricter than the regulatory floor, and packaging built to only the letter of Part 111 without tamper-evidence will fail vendor onboarding at most major chains before it ever becomes an FDA compliance question.

FDA's broader authority still applies

Even without a specific tamper-evidence mandate, a supplement product involved in an actual tampering incident, or sold in packaging that misleads consumers about its condition, can still trigger FDA action under the Federal Food, Drug, and Cosmetic Act's general adulteration and misbranding authority. The absence of a specific packaging mandate isn't the same as an absence of consequence if something goes wrong.

What this means for packaging decisions

Don't treat tamper-evidence as optional just because DSHEA and Part 111 don't spell out a specific mechanism, treat it as a retail-access requirement that happens to also be good practice. An induction seal under the closure, a shrink band, or a frangible tamper ring are all common, inexpensive ways to satisfy this in practice.

How we build it in

We spec tamper-evident features as standard on supplement bottle programs, not as an upsell, because it's functionally required for retail distribution even without a specific FDA packaging rule behind it. For closure sealing methods specifically, see Induction Sealing for Supplement Bottles.
