Westpak is certified to conduct product/package integrity testing to help guarantee successful delivery of products worldwide by any means of transportation.

Westpak is accredited to ISO/IEC 17025-2005, one of the most rigorous standards available for a mechanical testing laboratory.

Hazardous Materials

Some hazardous materials require special handling and extra care. Westpak has the expertise and capability to handle almost any type of material for the purpose of package HazMat testing and analysis.

The shipment of hazardous materials has long been recognized as a potential problem area, conceivably creating significant harm to the general public if incorrectly or haphazardly conducted. To help correct this potential problem, the United Nations established guidelines for individual countries to adopt in order to make codified regulations similar throughout the world, thus initiating a “UN certified package”.

In the United States, the Department of Transportation (DOT) established procedures that were subsequently published in 49-CFR (Code of Federal Regulations) and serve as the primary test protocols for “Hazmat” package testing.

UN Certification Symbol is necessary to ship packages containing Dangerous Goods; Westpak San Jose lab Identification Code is +CJ, and Westpak San Diego's code is +CL.

Hazardous materials packaging is highly regulated to protect both living beings and the environment. Regulations require that certification be obtained prior to shipping any packages containing hazardous goods in non-exempt quantities. The regulations resulted in procedures that require packages containing hazardous or dangerous goods to be subjected to Performance Oriented Package (POP) testing. This testing typically consists of a series or combination of impacts, stacking, vibration and pressure differential testing, among others.

To determine whether or not a product or material requires a UN certified package, one must first consult the 49-CFR standard to identify any requirements or special packaging instructions. Once it has been determined that a certified package is required, Westpak can assist in the process of providing the necessary testing and interpretation of the test results.

Westpak is certified to test the following non-bulk package types:

San Jose Facility                  San Diego Facility
Drums Drums
Metal Metal
Plastic Plastic


Wood (All Types)
Metal Wood (All Types)
Plastic Metal
Fiberboard Plastic

Paper Bags

Composite Packaging Paper
All Types  Textile
Large Packaging  Composite Packaging
Metal  All Types

In order to initiate a UN Certification Test, please click on the link below and download the UN Certification Sample Submission Form. The DOT requires that all specification, drawings and manufacturer’s identification/address be provided for all components of the package system. This includes the product, outer package, any inner packaging, tape, etc.

UN Certification Sample Submission Form

Once filled out, please email the submission form to proposals@westpak.com and you will receive a formal proposal for testing. Typically, a minimum of 8 package systems are needed for testing. Once the proposal is approved, please submit samples to Westpak for testing. Testing will be initiated and you will be contacted with a timeline of when the project will be completed.

Once testing is completed, a full test report will be issued documenting the test procedures, packages tested, results, along with a UN Certification Mark which can be printed on the outside of the package system per the guidelines of 49-CFR. 

Westpak facilities are certified to offer this type of testing and stand ready and able to assist you in the area of hazardous packaging certifications. If there are any questions regarding the form, sample size, or testing, please contact us.
