Stench Packaging
Stench Packaging
Some hazardous materials can create an obnoxious, penetrating odor that may contaminate other packages and pose undue risks in transportation. For this reason, UPS requires a packaging system to protect against the release of odors in case of leakage from a primary receptacle. Stench Packaging must have at least the following.

  • No more than one primary receptacle of glass, metal, or plastic
  • Cushioning material
  • Two intermediate containment systems of metal or plastic (for example, a metal can in a sealed plastic bag)
  • Corrugated box of minimum 275 lb Burst Strength or 44 ECT certification.

These components are the minimum required for containment of odors. The development of a UN performance package may require additional packaging materials. Any package designed to ship a material requiring "Stench Packaging" must meet the requirements of 49 CFR for performance packaging. Stench packaging requirements do not apply if a packaging authorization exception is provided in the chemical table for the material being shipped and the requirements of the exception are met.

If you have any questions about shipping hazardous materials with UPS, please call the UPS Hazardous Materials Support Center 1-800-554-9964.
