If you sell dietary supplements in the United States, child-resistant (CR) packaging isn't just a nice-to-have — for many products, it's required by federal law. The Poison Prevention Packaging Act (PPPA) mandates that certain household substances, including some supplements, must be packaged in CR containers.
1. What Is Child-Resistant Packaging?
Child-resistant packaging is designed to be significantly difficult for children under 5 years old to open, while remaining reasonably easy for adults. This is typically achieved through:
- Push-and-turn closures — similar to medicine bottles, requiring simultaneous pushing and twisting.
- Squeeze-and-turn closures — the cap must be squeezed on the sides while turning.
- Slide-and-lift mechanisms — common on carton-style boxes with a secondary locking tab.
2. Key US Regulations You Must Know
- 16 CFR §1700.20 — The CPSC standard that defines CR testing protocols. Packaging must pass tests with panels of children (50% failure rate) and adults (90% success rate).
- Poison Prevention Packaging Act (PPPA) — Federal law requiring CR packaging for hazardous household substances, including iron-containing supplements above 30mg per dose.
- State-level rules — Some states (e.g., California) have additional requirements for cannabis and CBD packaging.
3. How to Choose the Right CR Packaging
Consider these factors when selecting CR packaging for your supplement brand:
- Product type: Bottles, blister packs, and pouches each require different CR approaches.
- Target demographic: Senior-friendly CR options exist that remain compliant but are easier for elderly users.
- Brand experience: CR doesn't have to mean ugly. Custom-printed CR cartons with magnetic closures or hidden tabs maintain a premium feel.
- Cost: CR mechanisms add $0.02–$0.08 per unit. Factor this into your product margin.
