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.

Submitting Data Electronically

EPA requests that CRP protocol test data be made available to the Agency on a CD-R rather than a 3.5-inch floppy disk (per PR Notice 97-9), as the Agency has replaced the 3.5-inch floppy disk drives with CD/DVD readers on its computers. Any questions not covered in PR Notice 97-9 should be addressed to Lisa Pahel by telephone at (703) 347-0459, fax (703) 308-9382, or e-mail

Quick Reference Guide to Child-Resistant Packaging

This Quick Reference Guide to Child-Resistant Packaging is intended for use by pesticide registrants, product manufacturers, and others who are legally required to meet the EPA standards for child-resistant packaging of pesticide products. It describes various types of child-resistant packaging, along with their photographs, and how to obtain them.

Using the sortable table, Guide to CRP for Pesticides, you may search for a child-resistant package by one of the following topics. The table contains links to the child-resistant packaging descriptions and photographs in the fourth column.

  1. Package Type (e.g., aerosol overcap)
    The Package Type column lists the various packages alphabetically by their package type. Once you have selected a particular package you can see view the package description and photographs in the fourth column.

  2. ASTM Type
    The ASTM Type column lists the various packages by their ASTM classification of the package type (e.g., reclosable packaging – continuous thread closure). Once you have selected a particular package you can view the package description and photographs in the fourth column. If you are not familiar with the ASTM classification of CRP, use one of the other columns to locate the package.

    The following ASTM Classifications are included in the guide:

    • ASTM Type I - Reclosable Packaging Continuous Thread Closure
    • ASTM Type II - Reclosable Packaging Lug Finish Closure
    • ASTM Type III - Reclosable Packaging Snap Closure
    • ASTM Type IV - Unit Non-Reclosable Packaging Flexible (Strip/Pouch)
    • ASTM Type V - Unit Non-Reclosable Packaging – Rigid  
    • ASTM Type VII Aerosol Packages
    • ASTM Type VIII - Non-Reclosable Packaging Semi-Rigid (Blister)
    • ASTM Type IX - Dispensers (Not Intended To Be Removed)
    • ASTM Type X - Box Or Tray Package
    • ASTM Type XI - Reclosable Packaging Flexible
    • ASTM Type XIII - Reclosable Packaging Semi-Rigid (Blister)

  3. CRP Manufacturer
    The CRP Manufacturer column lists the various packages alphabetically by their manufacturer. Once you have selected a particular package you can view the package description and photographs in the fourth column.

  4. CRP Name
    The CRP Name column provides links to the package descriptions and photographs of each type of CRP.
