Dear Ms. Guffain:
This is in reference to your letter submitted on behalf of the Jimmy Sanders Company of Macon,
Mississippi. You inquired whether a particular fertilizer mixture would be considered a Class 9
material under the Hazardous Material Regulations (HMR; 49 CFR Parts 171-180). You state the
fertilizer is a blend of 31.25% ammonium nitrate; 20.83% phosphate and 47.91% potash by mass.
You also enclosed copies of a citation issued by Alabama Department of Public Safety's Motor
Carrier Safety Unit (Report No. ALJWQC002895) and the shipping paper for the shipment.
We hope you understand that RSPA cannot substitute our judgment for that of a judge or
magistrate that conducts a hearing on the citation. Any opinion we provide is based solely on the
information provided by you without an opportunity for the authority issuing the citation to present
its views and any additional information.
The answer to your question is yes, the material is listed in the §172.101 Table as "Ammonium
nitrate fertilizer; uniform non-segregating mixtures of nitrogen/phosphate or nitrogen/potash types
or complete fertilizers of nitrogen/phosphate/potash type, with not more than 70 percent
ammonium nitrate and not more than 0.4 percent total added combustible material or with not
The letters "A" and "W" in column 1 of the § 172.101 Table indicate the material is subject to the
more than 45 percent ammonium nitrate with unrestricted combustible material," 9, UN2071, III.
requirements of HMR only when transported by air or water.
It appears, however, on the shipping paper the material was described as "Ammonium nitrate
fertilizer, 5.1, NA2072, PG III (Oxidizer)". Under this description, the material would be subject
to the requirements of the HMR when transported by all modes.
I hope this information is helpful. Please contact us if we can be of further assistance.
Sincerely,
