Dear Ms. Schaaf:

This is in response to your inquiry concerning the pressure rating required for plastic drums used to transport 30% ammonium hydroxide under the Hazardous Materials Regulation (HMR; 49 CFR Parts 171-180).  You submitted a Material Safety Data Sheet and a vapor pressure curve with your inquiry.

Under § 173.22, it is the shipper's responsibility to determine that the packaging or container is an authorized packaging, including part 173 requirements, and that it has been manufactured, assembled, and marked in accordance with part 178.  However, based on the information you provided, it is the opinion of this office that a hydrostatic test pressure of at least 300 kPa is required for the plastic drums.

I hope this information is helpful.

Sincerely,

John A. Gale
Transportation Regulations Specialist
Office of  Hazardous Materials Standards
