How CPSC Testing Works: The 16 CFR 1700.20 Standard Explained for Consumers

When you buy medicine, supplements, household cleaners, nicotine products, or other items that could harm a child, the packaging is not supposed to be “safe-looking” by accident. In many cases, it must follow specific child resistant packaging testing requirements before it can be considered child resistant.

For parents, caregivers, and everyday shoppers, this matters because a safety cap is more than a design feature. It is meant to slow children down while still allowing adults to use the product properly. The U.S. Consumer Product Safety Commission explains that special packaging is designed to be significantly difficult for children under five to open within a reasonable time, while not being difficult for adults to use properly.

This guide breaks down how CPSC testing works, what 16 CFR 1700.20 means, and how consumers can use this information when choosing and storing products at home.

What 16 CFR 1700.20 Means for Shoppers

16 CFR 1700.20 is the testing procedure used for certain types of special packaging. In simple terms, it explains how child-resistant packages are tested with children and adults before they can be treated as compliant under relevant rules.

These child resistant packaging testing requirements are part of a larger safety system connected to the Poison Prevention Packaging Act. The goal is not to make packaging impossible to open. The goal is to reduce the risk that young children can quickly access harmful household substances.

For shoppers, this helps explain why some bottles, pouches, and containers feel harder to open than regular packaging. That extra step is intentional. It may be a push-and-turn cap, a squeeze-and-turn closure, a locking pouch, or another design that requires more coordination than most young children have.

The CPSC also notes that special packaging is commonly referred to as child-resistant and senior-friendly packaging. That balance matters because packaging must protect children without making essential products unusable for adults.

Why Child Resistant Packaging Testing Requirements Exist

The main reason child resistant packaging testing requirements exist is to reduce accidental poisoning and injury in the home. Many everyday products can be dangerous if a child opens them, swallows them, inhales them, or gets them on their skin.

These products may include:

• Prescription medicines
• Over-the-counter medicines
• Iron-containing supplements
• Certain cosmetics
• Household chemicals
• Cleaning products
• Pesticides
• Nicotine products
• Some cannabis or CBD products, depending on local laws

The PPPA applies to certain household substances, including hazardous substances, foods, drugs, cosmetics, and certain fuels stored for household use.

This is why child resistant packaging regulations are not just technical rules for companies. They directly affect the products families bring into their homes.

How the CPSC Child Test Works

The child portion of the test focuses on children between 42 and 51 months old. The testing procedure states that children are selected across three age ranges: 42–44 months, 45–48 months, and 49–51 months.

The test may begin with 50 children and, if results are inconclusive, continue with additional groups of 50 children, up to 200 children total.

During the child test, children are usually tested in pairs in a familiar setting, such as a nursery school or kindergarten. They are handed identical packages and asked to try to open them. The testing process is controlled so that children are not told the test is a game, are not offered rewards, and are not encouraged to race.

The first period lasts up to five minutes. If the child does not open the package, the tester demonstrates opening a separate package, then the child gets another five minutes to try again.

These CPSC testing requirements are designed to answer a practical question: can young children gain access to the contents within the test period?

What Counts as a Failure in Child Testing

In the child test, a package failure generally happens when a child opens the special packaging or gains access to the contents. For unit packaging, such as blister packs, a failure may occur if the child opens enough individual units to access a potentially harmful amount, or more than eight units, whichever number is lower.

This matters for consumers because “child resistant” does not mean “childproof.” It means the package passed a defined test under specific conditions.

For packaging to be child-resistant, at least 85% of tested children must not open the package during the first five minutes, and at least 80% must not open it during the full 10-minute test.

That is one of the most important child resistant packaging testing requirements for parents to understand. The standard reduces risk, but it does not guarantee that every child will be unable to open the package.

How the Adult Test Works

Child-resistant packaging also has to be usable by adults. This is important because medicine, cleaners, and other products still need to be accessible to the people who use them properly.

Under the adult testing process, adults are asked to open and, where appropriate, properly close the package according to the instructions that appear on the packaging. Senior adults in the test are given up to five minutes to open and close the first package, then one minute for a second identical package.

At least 90% of adults must be able to open the package within five minutes and, if applicable, properly resecure a second package within one minute.

This part of the CPSC testing requirements matters because packaging that protects children but cannot be used correctly by adults can create another safety problem. If adults struggle too much, they may leave caps loose, transfer products to easier containers, or avoid reclosing the package properly.

Child Test Compared With Adult Test

Why Child Resistant Does Not Mean Childproof

One of the biggest misunderstandings about child resistant packaging testing requirements is the belief that passing the test means no child can ever open the package.

That is not true.

Children learn by watching adults. Some children are stronger, more patient, or more curious than others. Older siblings may also open packages that younger children cannot. This is why the safer mindset is to treat child-resistant packaging as a backup layer, not the main safety system.

Even when a product meets child resistant packaging regulations, it should still be stored:

• High up
• Out of sight
• Out of reach
• In its original container
• Away from food and snacks
• Behind a cabinet lock when possible

The packaging helps. Your storage habits matter more.

What CPSC Requirements Mean When You Buy Products

For consumers, CPSC requirements are most useful when they help you make better buying and storage decisions.

When buying a potentially harmful product, check for:

• A child-resistant closure
• Clear opening instructions
• A cap that locks back into place
• Packaging that does not look damaged
• Tamper-evident seals where appropriate
• Warning labels about children or household storage

Also pay attention to products that say “not child resistant” or “for households without young children.” Some regulated products may have one non-complying package size if properly labeled, while compliant popular-size packages are also supplied.

That warning is not just fine print. If you have children at home or children visit your home, choose the child-resistant option whenever possible.

Common Products That May Need Extra Attention

Several household products deserve extra caution, even when they appear ordinary.

Medicines are the most obvious category. Pain relievers, sleep aids, allergy tablets, cough syrups, and prescription drugs should always be closed and stored immediately after use.

Supplements also matter. Vitamins, iron supplements, and high-dose formulas can be harmful if a child takes too much.

Cleaning products should be treated as high-risk. Bright colors, pleasant smells, and spray bottles can attract children.

Cosmetics and personal care items can also be risky. Some products may contain ingredients that are unsafe if swallowed.

Nicotine and vape products require serious caution because small amounts of nicotine can be dangerous for children.

Understanding child resistant packaging regulations helps shoppers recognize that many ordinary-looking products may still need strict storage at home.

What to Do After Opening a Child-Resistant Package

A package only helps if it is closed properly after every use. Many home safety risks happen after an adult opens a product and forgets to resecure it.

After every use:

• Twist the cap until it locks
• Check for a click or resistance
• Reseal locking pouches fully
• Keep blister packs inside the original box
• Put the product away immediately
• Never leave medicine on counters, beds, or side tables

The CPSC requirements behind the packaging assume that the package is used correctly. A child-resistant cap left loose on a counter is no longer performing its safety role.

Conclusion

Understanding child resistant packaging testing requirements helps consumers see safety packaging more clearly. A push-and-turn cap, locking pouch, or blister pack is not just inconvenient packaging. It is part of a tested safety system designed to reduce the chance of children accessing harmful products.

At the same time, no packaging can replace careful storage. Even products that meet child resistant packaging regulations, follow CPSC testing requirements, and satisfy relevant CPSC requirements should be closed properly and stored away immediately after use.

For parents, caregivers, and everyday shoppers, the safest approach is simple: choose child-resistant packaging when available, read warning labels, check seals, close products fully, and keep anything risky out of reach every time.

Frequently Asked Questions

What Are Child Resistant Packaging Testing Requirements?

Child resistant packaging testing requirements are the testing rules used to check whether young children can open certain packages and whether adults can use them properly. Under 16 CFR 1700.20, testing includes child panels and adult-use testing for qualifying special packaging.

What Are CPSC Testing Requirements?

CPSC testing requirements are the procedures used to evaluate whether packaging meets child-resistant and adult-friendly standards. For special packaging, these procedures are outlined in 16 CFR 1700.20.

Do CPSC Requirements Mean a Package Is Completely Childproof?

No. CPSC requirements help determine whether packaging is child-resistant, not childproof. Parents and caregivers should still store risky products out of sight and reach.

Why Do Child Resistant Packaging Regulations Matter for Parents?

Child resistant packaging regulations matter because they help reduce the chance that young children can quickly open harmful products. They are especially important for medicines, supplements, cleaners, nicotine products, and other household items that may cause injury or poisoning.

Should I Still Lock Products Away if They Meet Child Resistant Packaging Testing Requirements?

Yes. Even if a product meets child resistant packaging testing requirements, it should still be locked away or stored high, out of sight, and out of reach. Packaging is only one layer of protection.
