Specifically, you state that a freight forwarder refused to process your shipment because the words “US DOT” were on the shipping paper in association with the hazardous materials description. You state that the description on the shipping paper appeared as “US DOT: UN1760, Corrosive Liquid, N.O.S. (Nitrilotrimethylenetris (Phosphoric Acid)), 8, III, ERG 154, Danger Label: 8.” Lastly, you seek confirmation that your understanding is correct that the basic description is in the correct sequence and is not interspersed with additional information. Based on the information you have provided, it appears that your understanding is correct. As specified in § 172.202(b), the basic description specified in § 172.202(a)(1) through (4) must be shown in sequence with no additional information interspersed. It appears that the basic description you have provided is in the correct sequence and the additional information is outside of that description. I hope this information is helpful. Please contact us if we can be of further assistance. Sincerely, Shane C.

The following is the completed description on the BOL US DOT: UN 1760 CORROSIVE LIQUID, N.O.S.(NITRILOTRIMETHYLENETRIS(PHOSPHORIC ACID), 8, III, ERG 154, Danger Label: 8 49 CFR 172.202 states that the basic shipping descriptions contains the: (a) The shipping description of a hazardous material on the shipping paper must include: (1) The identification number prescribed for the material as shown in Column (4) of the § 172.101 table; (2) The proper shipping name prescribed for the material in Column (2) of the § 172.101 table; (3) The hazard class or division number prescribed for the material, as shown in Column (3) of the § 172.101 table and the subsidiary hazard class when applicable; and (4) The packing group in Roman numerals, as designated for the hazardous material in Column (5) of the § 172.101 table.

DE204803343 www.master-builders-solutions.com » » <<>> Page 2 of 2 Except as provided in this subpart, the basic description specified in paragraphs (a)(I), (2), (3), and (4) of this section must be shown in sequence with no additional information interspersed. For example, "UN2744, Cydobutyl chloroformate, 6. I, (8, 3), PG II." Shipping descriptions for hazardous materials offered or intended for transportation by rail that contain all the information required in this subpart and that are formatted and ordered in accordance with recognized electronic data interchange standards and, to the extent possible, in the order and manner required by this subpart are deemed to comply with this paragraph. In my opinion on this occasion the freight forwarder is incorrect in their determination because the basic description that is included above is in the correct sequence and it is not interrupted or interspersed. Am I correct in my determination? Hom Stak Vorm Stollber Global Dangerous Goods Expert Master Builders Solutions »» - **truncated:** false - **body characters:** 4549
