Explanatory Note

This Equivalency Certificate allows the applicant to transport a solution of 1H‑Tetrazole as a FLAMMABLE LIQUID. In a solution where the explosive properties are suppressed, it becomes a desensitized explosive meeting the classification criteria of a flammable liquid.

The Transportation of Dangerous Goods Regulations have been amended to add the new and more accurate shipping name, UN3379, DESENSITIZED EXPLOSIVE, LIQUID, N.O.S., Class 3, Packing Group I. Please note that Equivalency Certificate SU 5985 (Ren. 11), which authorizes the use of UN1993, FLAMMABLE LIQUID, N.O.S. to classify the solution of 1H‑Tetrazole, will not be renewed after its expiry date of January 31, 2019. Sigma-Aldrich Canada Co. will need to properly classify the dangerous goods as UN3379.
