Broad St.\nPhillipsburg, NJ 08865\nDear Ms. Curcio:\nThis is in response to your letter requesting clarification of the Hazardous Materials\nRegulations (HMR; 49 CFR Parts 171-180) pertaining to the transportation of various\nconcentrations of silver nitrate. You ask whether diluted forms of silver nitrate are\nregulated under the HMR.\nUnder the HMR, if diluted solutions of silver nitrate (composition of solutions were not\nincluded in your letter) do not meet the definition for Division 5.1 (oxidizers) materials in\n§ 173.127, and do not meet the definition of any other hazard class, hazardous substance\nor hazardous waste, the material is not regulated under the HMR.\nI hope this information is helpful. Please contact this office should you have additional\nquestions.\nSincerely,\nHith Till\nHattie L.

We currently classify our concentrated silver nitrate products as listed\nin the 49 CFR under the UN1493 classification. However, we also carry some very\ndiluted forms of silver nitrate that we feel is not hazardous enough to be a regulated\nitem. We have been using a previously issued exception letter, Ref. No. 00-0249,\naddressing a similar concern regarding an exception for shipments of water samples\nis with some quidance for the hazard determination of some of our Hvdrochloric\nontaining various limited quantities of Class 8, corrosive materials. This letter provide\nSulfuric and Nitric Acid solutions.\nI would appreciate it if you can please reply back with an official interpretation from the\nhazmat administration as to whether or not there can be a similar exception made for\nsilver nitrate (UN1493) with specific concentration cut-offs or limitations.\nMallinckrodt Baker, Inc.\n600 N.
