An example of DOT guidance for classification of materials for shipping is availableat http://www.drs.illinois.edu/transportationandshipping/definitions.html.  As shown at this source (see Division 5), nitrates are among the class of "oxidizers" in accordance with 49 CFR 173.127 and 173.128.   These federal regulations are at edocket.access.gpo.gov/cfr_2009/octqtr/pdf/49cfr173.127.pdf .  In accordance with the regulations, an oxidizer other than an organic peroxide is Class 5, Division 1.

The details regarding the percent composition and amount ina package define a packagomg requirement.  There is a small quantity exception -- which often applies to research samples transported for analysis.  The quantity in a single package is a very important factor.  

I strongly recommend a phone call to the PHMSA's Hazardous Materials Information Center at (800) 467-4922.  Describe the specific situation, and potential situations in the future.  The regulations are very detailed and "tricky" with respect to specific situations. Interpretation by a trained expert is highly advised.   Preferably, your institution has a trained/certified packaging and transportation expert who will assure that  (a) the interior/exterior packaging, the (b) external labels and markings, and (c) the shipping manifest ALL conform with the detailed requirements.  Transferring responsibility to an expert who is responsible to the institution as a whole relieves an amateur of liability.   An MSDS(s) may be required in the package.  Making an effort to do it correctly is much better than paying a stiff fine for non-compliance.

Subject: [DCHAS-L] Testing company for oxidizer determination

We have a colleague with the following question.  Can anyone point him in the direction of a testing lab or other expert that can make the determination?

You can reply directly to me and Iwill collate the responses and post them to the list in a single post.

Thanks,

Rob Toreki

Where can I send a sample of liquid to have a determination done as toclassification for shipping/storage/handling purposes as to whether it is an oxidizer?
 
It is essentially a suspension of zinc oxide, withsome sodium nitrate.
