Model Rocket Motor and Toy Propellant Device (USPS)

Basic Description: Model Rocket Motor, NA0323 or Articles Pyrotechnic, UN0432

1.2 HAZARDOUS INGREDIENTS / IDENTITY INFORMATION

Model rocket motors consist of a pyrotechnic composition (Black powder consisting of
74% KNO3 as an oxidizer and a combination of 15.6% C and 10.4% S as a fuel plus
binder) encased in a paper tube capped at each end with inert clay material. No
chemical composition is exposed during normal handling and storage. All percentages
are by weight.

The U.S. Department of Transportation (D.O.T.) classifies these items as UN I.4S
explosives. The D.O.T. classification reference numbers that may apply include the
