Child-Resistant Packaging for Pesticides

To protect children from poisonings around the home, the law requires that certain household pesticides be in child-resistant packaging (Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) section 25 (c)(3)). EPA's pesticide regulations for Child-Resistant Packaging (CRP) are located at 40 CFR 157 subpart B.

Does Your Pesticide Product Require Child-Resistant Packaging?

If a pesticide product triggers the CRP toxicity criteria and is used in a residential setting, then it is subject to CRP. A pesticide product triggers the CRP toxicity criteria when, based upon testing with an appropriate test species, it meets anyone of the following:

  • Acute oral LD50 of 1.5 g/kg or less.
  • Acute dermal LD50 of 2000 mg/kg or less.
  • Acute inhalation LC50 of 2 mg/ liter or less.
  • Is corrosive to the eye (causes irreversible destruction of ocular tissue) or causes corneal involvement or irritation persisting for 21 days or more.
  • Is corrosive to the skin (causes tissue destruction into the dermis and/or scarring) or causes severe skin irritation (severe erythema or edema) at 72 hours.
  • The pesticide or device has such characteristics that, based upon human toxicological data, use history, accident data or such other evidence as is available, the Agency determines there is serious hazard of accidental injury or illness which child-resistant packaging could reduce.

What is Necessary if Your Product Requires CRP?

Questions and Answers about Implementing Child Resistant Packaging:

What is CRP?

CRP is defined in 40 CFR 157.21(b) as packaging that is designed and constructed to be significantly difficult for children under 5 years of age to open or obtain a toxic or harmful amount of the substance contained therein within a reasonable time, and that is not difficult for normal adults to use properly.  

Can CRP be used voluntarily?

Yes, per 40 CFR 157.30, but all the requirements for CRP must be met.  

What happens if I want to change the CRP?

You must submit to EPA:
  • an application to amend the product registration; and
  • a new CRP certification.

What CRP does EPA require for unit dose packaging?

The CRP generally may be either the outer retail package or the individual unit package. However, prefilled, nonrefillable insecticide bait stations not designed or intended to be opened or activated in a manner that exposes the contents to human contact must be in CRP rather than the outer package (PR 97-9).

What does “opened” in the Senior Adult Use Effectiveness (SAUE) mean to EPA?

EPA will consider a package successfully “opened” in SAUE testing only if the contents of the package can be removed in a condition suitable for their intended use, and the process of opening and removing the contents would not result in significant exposure to the pesticide.

When does my product require CRP?

  • When it meets the toxicity criterion in 40 CFR § 157.22(a) and the product’s labeling either directly recommends residential use or reasonable can be interpreted to permit residential use [40 CFR § 157.22(b)].
  • Exemptions are clearly described in 40 CFR§ 157.24

What is required for unit-dose packaging?

  • For the purposes of CRP testing, a child failure is opening or access to a toxic or harmful amount or more than 8 units, whichever number is lower, based on an 11.4kg child. Testing that demonstrates safety below a toxic or harmful dose is required.
  • We are planning on putting various fill volumes inside identical CRP packaging. Can I bracket test?
    • To align regulatory practices with CPSC, EPA is accepting bracket testing to satisfy testing requirements for unit-dose packaging which houses various fill volumes. The smallest, largest, and a middle quantity for each container size must be tested.
    • Bracketed tests do not need to come in under PRIA, but the certification statement must differentiate which fill volumes were tested and which were waived due to bracket testing.
    • Example:

Fill Volume

Container Size

Child Testing Required?

SAUE Testing Required?







Bridging could be used to satisfy these fill volumes

Bridging could be used to satisfy these fill volumes















Bridging could be used to satisfy these fill volumes

Bridging could be used to satisfy these fill volumes









Note: Additional testing may be required at EPA discretion

  • Can I use existing data to support different packaging?
    • EPA will entertain data bridging proposals beyond the bracket testing on a case by case basis.
    • These must be submitted to the Agency under PRIA Code R272 which include data summary sheets for all supporting CRP and SAUE studies.

When is a CRP Certification Appropriate?

  • A certification statement must be submitted with each application for new registration, if applicable.  If EPA determines that a currently registered product is required to be packaged in CRP, a certification must be submitted within 6 months after the Agency notifies the registrant of the requirement.

What information needs to be included in a certification statement?

  • The product name and EPA registration number
  • A description of the package tested
  • Whether CRP for this product voluntary or required
  • For each package: Testing information for the child-resistant effectiveness
    • Number of children tested
    • Number of children opening/accessing contents in full 10 minutes
  • For each package: Testing information for senior adult use effectiveness:
    • Number of adults tested
    • Number of adults unable to access package contents
  • Include the certification statement (I certify that the packaging used for this product meets the standards of 40 CFR 157.32 including the revised standards in 16 CFR 1700.15(b) when tested by the revised testing procedures in 16 CFR 1700.20 as published in 60 FR 37710 (July 21, 1995)) and your signature

What do I need to submit to the Agency?

  • New products or products newly fitting the criterion for CRP requirements – include the CRP certification in their initial application package to the Agency.
  • Revisions to CRP packaging – submission of CRP certification may be submitted as a fast-track amendment, submission of CRP data must be submitted as a PRIA R340.
  • Bridging rationales – PRIA R272 code for products within the Registration Division and A385 or A540 for products within Antimicrobials Division.
  • Exemptions which require Agency approval – PRIA R340, including all the information from 40 CFR 157.24(b).
  • Full data is not required as part of your Agency submission, but if requested, must be provided to the Agency within 6 weeks.

What records pertaining to CRP do I need to keep?

  • Follow 40 CFR 157.36 recordkeeping requirements – “For as long as the registration of a pesticide product required to be in CRP is in effect, the registrant must retain the records listed in this section.  The registrant must, upon request by the Agency, make them available to the Agency representatives for inspection and copying, or must submit them to the Agency.”
  • Upon request, the registrant must submit a description of the package, certification statement, and test data.
  • EPA will be performing product audits to ensure compliance with CRP recordkeeping.

Do I need to submit anything now?

We will be updating our records based on previously submitted data and certifications, but to expedite this process, please include a copy of the certification statement in your next Agency submission.
