Child-Resistant Packaging Requirements Explained

What special packaging means in practice

Under the Poison Prevention Packaging Act, special packaging is defined as packaging that is significantly difficult for children under 5 to open yet relatively easy for an adult to open. CPSC also calls this child-resistant and senior-friendly packaging. The PPPA special packaging requirements are codified at 16 CFR part 1700. CPSC administers the PPPA and EPA administers FIFRA, and regulations under both laws require special packaging for certain products.

This is a package performance concept, not a label or a single closure feature. A package can look secure and still fail the child test, or pass a test and still be unsuitable if the contents interact with the closure, liner or seal. CPSC does not perform pre-market approval and does not approve, certify or endorse a specific package or design. The end product manufacturer is responsible for selecting suitable packaging and ensuring compliance.

The regulated package is usually the primary package

The PPPA requirement applies to the primary or immediate package, meaning the package in direct contact with the regulated substance. Using special packaging only for secondary packaging, such as an outer carton holding individually wrapped products, would not satisfy that requirement. Start by mapping every child-access path: bottle, pouch, blister, tube, closure, liner and inner seal.

For a kit, ask which immediate container holds the regulated substance and whether each container needs its own review. Do not assume the outer box, display tray or shipper does the work. Those components may carry warnings or instructions, but they are not a substitute for a compliant immediate package. Confirm the exact configuration with your converter and qualified counsel.

The two performance gates: child test and adult test

The child test has two gates. At least 85 percent of tested children must not open the package during the first 5 minutes, and at least 80 percent must not open it during the full 10 minutes. The adult test requires at least 90 percent of adults to open the package within 5 minutes and, if applicable, properly resecure a second package within 1 minute. The protocols are in 16 CFR 1700.20.

A hypothetical percentage exercise illustrates the arithmetic, not a test design or regulatory acceptance rule. For 50 children, 85 percent is 42.5: 43 of 50 is 86 percent, while 42 of 50 is 84 percent. Likewise, 40 of 50 is 80 percent and 39 of 50 is 78 percent. For adults, 45 of 50 is 90 percent, but that calculation alone does not establish compliance with opening and applicable resecuring requirements. Actual panel composition, participant success criteria and acceptance decisions must follow 16 CFR 1700.20.

Additional requirements can attach to the substance

Additional requirements can attach to the substance. CPSC notes that a package may need to keep functioning for the life of the product, avoid being rendered ineffective by interference or reaction with the contents, not be reused, and include a restricted-flow mechanism. These requirements are outlined at 16 CFR 1700.15, and the applicability of each one is stated under each regulated substance at 16 CFR 1700.14. Review the package and the formulation together.

Treat compatibility as a technical question, not a guess. Ask the supplier for compatibility data covering the intended formulation and package components. We recommend having qualified specialists define compatibility and functional testing for the production configuration, including fill level and closure torque where relevant. Separately, human-panel testing must use the contents and preparation specified by the applicable protocol. If the package is designed for refilling, flag that for review rather than assuming it is acceptable.

Package types and ASTM D3475 vocabulary

ASTM D3475 is a voluntary standard that classifies special packaging by the type of closure and the action needed to open it. CPSC lists the following general types: - Reclosable continuous thread closures - Lug finish closures - Snap closures - Unit non-reclosable flexible strip or pouch formats - Unit non-reclosable rigid formats - Unit reclosable packages - Aerosols - Non-reclosable semi-rigid blisters - Dispensers not intended to be removed - Box or tray packages - Reclosable flexible packages - Dispensers that may be removed - Reclosable semi-rigid blisters Use this vocabulary to brief suppliers, converters and test labs.

The CPSC Special Packaging Index lists manufacturers that have self-identified to CPSC, but it is not a comprehensive list and CPSC staff has not verified the manufacturers' test data. Treat the index as a starting point for supplier conversations, not as an approval list. With any packaging supplier, we recommend agreeing on the intended ASTM type and opening action before samples are made, because those choices affect the package and the user instructions.

A practical review checklist

Keep the checklist as a living record. Update it after any material, closure, liner, supplier or content change.

• List every SKU, substance, concentration, package format and closure.
• Confirm the primary package and every child-access path.
• Obtain current regulatory text and the substance-specific listing.
• Ask the packaging supplier for the ASTM type, prior test reports, compatibility data and use restrictions.
• Ask the test lab for the protocol under 16 CFR 1700.20 and whether the sample matches production.
• Test worst-case contents, fill level, torque, liner and aging conditions as advised.
• Review opening and resecuring instructions because adult-friendly performance matters.
• Keep drawings, specifications, test reports, the GCC and change records in one file.
• Separate arithmetic estimates from validation testing.
• Separate commercial terms from compliance evidence. Teal's standard MOQ is 50 units and specialty rigid MOQ is 100, and Teal does not charge setup, plate or tooling fees. Those terms do not replace testing or a GCC.

Scope limits and what this guide does not decide

This guide is Teal's editorial planning framework, not legal advice or a compliance determination. It does not decide whether your substance is regulated, which protocol applies, whether a package passes, or what your channel requires. CPSC does not approve, certify or endorse packages, designs, consultants or testing firms. Confirm current requirements with qualified counsel, a qualified test lab, your converter and your own GCC process. If a retailer or marketplace asks for documentation, confirm the exact requirement in your own agreement.

Do not carry a test result from one package to another size, closure, liner, content or supplier without review. Do not treat a supplier's statement, a stock component or a marketing term as proof of performance. Teal does not certify child resistance and does not issue a GCC for your product. Keep drawings, specifications, test reports and change records in one review file.
