Dear Mr. Rornach:

This responds to your November 3, 2003, letter requesting clarification on packaging under the Hazardous Materials Regulations (HMR; 49 CFR Parts 171-180).  You ask whether a sift-proof bulk bin may be used as both a bulk package for a Division 4.1 material and a freight container for limited quantity packages of a Class 3 material.  Specifically, you ask if it is permissible to ship limited quantity packages of “Flammable liquid, n.o.s. (toluene, xylene), UN 1993, PG II”, each marked with the proper shipping name and UN number and “Ltd.  Qty.” in a leakproof, sift-proof bulk bin containing otherwise unpackaged “Solids containing flammable liquid, n.o.s. (toluene, xylene), 4. 1, UN 3175, PG II” material.

The answer to your question is no.  A freight container that is the bulk packaging for an unpackaged hazardous material may not be used simultaneously as a freight container for the shipping of packaged hazardous material.  Such usage is inconsistent with the definition for “bulk packaging” and would result in incongruous quantity descriptions on the shipping paper.  Therefore, the limited quantity Class 3 material packages must be shipped separately from the package containing the bulk solid Division 4. 1 material.

I hope this answers your inquiry.
