FDA Guidance on Child-Resistant Packaging: Testing and Exemptions

Child-resistant packaging in the United States is not an FDA program. The requirements come from the Consumer Product Safety Commission under the Poison Prevention Packaging Act of 1970, codified at 15 U.S.C. §1471–1476, with the implementing rules at 16 CFR Part 1700.¹ The FDA administered the PPPA only until 1973, when authority moved to the newly created CPSC, and the CPSC has been the sole federal authority for child-resistant packaging standards ever since.² If you are looking for FDA guidance on the subject, you are looking in the wrong place: the standards, the testing protocol, the exemptions, and the certification duties all live with the CPSC.

The PPPA defines “special packaging” as a container designed to be significantly difficult for children under five to open in a reasonable time, while remaining usable by normal adults.³ Everything else in the rulebook flows from that two-part definition.

Which Products Must Use Child-Resistant Packaging

The regulated substances are listed at 16 CFR 1700.14. The categories below are the ones that catch most manufacturers, pharmacists, and consumers.

Prescription Drugs

Nearly all oral human prescription drugs must be dispensed in child-resistant packaging, with a short list of specific exemptions discussed further down.⁴

Over-the-Counter Pain Relievers

Several common analgesics trigger the requirement once the total amount in the retail package crosses a threshold. The thresholds apply to the whole package, not per dose:

Aspirin: any oral aspirin-containing preparation, with limited exceptions for certain effervescent and unflavored powder formulations.
Acetaminophen: packages containing more than one gram total.
Ibuprofen: packages containing one gram (1,000 mg) or more.
Naproxen: packages containing the equivalent of 250 mg or more.
Ketoprofen: packages containing more than 50 mg.

Iron-Containing Drugs and Supplements

Prescription iron products and dietary supplements both fall under the rule when a single package holds the equivalent of 250 mg or more of elemental iron. The concentration must also meet a minimum: 0.025 percent weight-to-volume for liquids or 0.05 percent weight-to-weight for non-liquids.⁵

Household Chemicals

Thresholds vary by chemical form:

Methyl salicylate: liquid preparations containing more than 5 percent by weight, except pressurized spray containers.
Turpentine: liquid household substances containing 10 percent or more by weight.
Sodium or potassium hydroxide: dry granules, powder, and flakes at 10 percent or more by weight; all other forms, including liquid drain cleaners, at just 2 percent or more by weight.

The hydroxide rule catches people off guard. A liquid drain cleaner triggers the packaging requirement at 2 percent, while the dry-form threshold is five times higher.

Liquid Nicotine

The Child Nicotine Poisoning Prevention Act of 2016, at 15 U.S.C. §1472a, requires child-resistant packaging for any container from which nicotine in solution or other form is accessible through normal consumer use, regardless of concentration. Sealed, pre-filled disposable containers that plug directly into an e-cigarette device are excluded, so long as the nicotine inside stays inaccessible through normal handling, including foreseeable contact by children.⁶ These containers must meet the same performance standards as other PPPA products.

What “Child-Resistant” Means in Testing

The performance standard at 16 CFR 1700.20 has two parts, and packaging must pass both.

The child test starts with a panel of 50 children aged 42 to 51 months, split by prescribed age bands: 30 percent at 42–44 months, 40 percent at 45–48 months, and 30 percent at 49–51 months. Each child gets five minutes to try to open the package, then sees a demonstration, then gets another five minutes. Depending on the results, additional panels of 50 are tested up to a maximum of 200 children.⁷ At the full panel, the effective benchmarks work out to roughly no more than 15 percent of children opening the package in the first five minutes and no more than 20 percent across the full ten.

The adult test uses a panel of 100 senior adults, split 25 percent aged 50–54, 25 percent aged 55–59, and 50 percent aged 60–70. At least 90 percent must open the package within five minutes and, where applicable, properly resecure a second package within one minute.⁸ A separate younger-adult panel (100 people aged 18–45, 70 percent female) is also tested.⁷

One point manufacturers sometimes miss: the packaging must keep working for the life of the product. A closure that passes the initial test but loosens after a few open-and-close cycles does not comply.⁸

Exemptions

The law and regulations recognize that child-resistant packaging is not always appropriate.

Under 15 U.S.C. §1473(b), a prescription drug otherwise subject to the standard may be dispensed in a regular container when the prescribing physician, dentist, or other licensed practitioner directs it, or when the patient requests it. This is the broadest exemption in the law.⁹

The regulation itself exempts a defined set of drugs and dosage forms. The list includes sublingual nitroglycerin tablets, low-dose sublingual and chewable isosorbide dinitrate (10 mg or less), oral contraceptives in memory-aid dispensers, conjugated estrogen tablets in memory-aid packages of 32 mg or less, anhydrous cholestyramine powder, unit-dose potassium supplements at 50 milliequivalents or less per dose, certain low-dose prednisone packages, and pancrelipase preparations, among others.⁴ The rationale runs to small doses, forms that already limit access such as blister packs, or emergency-use drugs like nitroglycerin.

For regulated over-the-counter products, a manufacturer may market a single package size in non-compliant packaging as long as a compliant size is also offered. The non-compliant package must carry the statement “This Package for Households Without Young Children” on every principal display panel, in capital letters inside a bordered rectangle, at a letter height specified by panel area.¹⁰

Certification and Recordkeeping

Domestic manufacturers and importers must issue a General Certificate of Conformity attesting that the packaging meets 16 CFR 1700.15 and passed testing under 16 CFR 1700.20. The GCC must describe the product, cite the specific CPSC rule, and identify the manufacturer or importer, the date and place of manufacture, and the date and place of the supporting testing.¹¹ The party that actually packages the substance in special packaging issues the certificate; for imported products, that duty falls on the importer.¹²

Supporting test data must be retained. A copy of the GCC must be produced to the CPSC or U.S. Customs and Border Protection within 24 hours of a request.¹³

Importers should also mark their calendars for July 8, 2026. That is the full implementation date for the CPSC’s eFiling program, which will require certificate data to be submitted electronically through CBP’s Automated Commercial Environment system. Until then, importers must be able to produce certificates on request but are not required to file them proactively.¹⁴

When Packaging Fails: Reporting and Recalls

A manufacturer, distributor, or retailer that receives information reasonably suggesting its product could create a safety hazard must report to the CPSC within 24 hours. A company has up to 10 working days to investigate whether the information is reportable, but once it concludes that it is, the 24-hour clock starts immediately.¹⁵ A child-resistant closure that fails to resist children is treated the same as any other product defect for reporting purposes. You do not need actual injury reports to trigger the duty.

Once a product is reported or otherwise identified, the CPSC may pursue a voluntary or mandatory recall. Corrective actions can include refunds, replacements, packaging repairs, or public hazard notices.¹⁶ Companies that fail to report known defects, or that violate packaging requirements outright, face civil penalties that the CPSC adjusts annually for inflation, with recent late-reporting cases resolved in the millions of dollars.
