Dear Ms. Dean:
This is in response to your April 4, 2005 letter regarding the appropriate shipping description for various fertilizer blends under the Hazardous Materials Regulations (HMR; 49 CFR Parts 171-180). Specifically, you ask about the appropriate shipping descriptions for two fertilizer blends. The first blend consists of 81% ammonium nitrate, 0-2% talc or conditioning agent, and 19% mono ammonium phosphate. The second fertilizer blend consists of 66% ammonium nitrate, 19% mono ammonium phosphate, and 15% potash.
Section 173.22 specifies that it is the shipper’s responsibility to properly class and describe a material in accordance with the HMR. This office does not perform that function. However, based on the information provided, it is our opinion that the first fertilizer blend specified should be described as “Ammonium nitrate based fertilizer, 5.1, UN2067” and the second fertilizer blend should be described as “Ammonium nitrate based fertilizer, 9, UN2071.”
I hope this information is helpful.
Sincerely,
Hattie L. Mitchell, Chief
