Phillips\nSenior Regulatory Affairs Manager - Americas\nICL Americas\n622 Emerson Rd.\nSuite 500\nSt. Louis, MO 63141\nReference No. 20-0045\nDear Mr. Phillips:\nThis is in response to your May 26, 2020, letter requesting clarification of the Hazardous\nMaterials Regulations (HMR; 49 CFR Parts 171-180) applicable to lading density and the\nmaximum weight of lading when loading cargo tanks. Specifically, you ask whether a previous\nLetter of Interpretation (LOI) issued under Reference No. 96-0182 on September 25, 1996,\nremains valid.\nThe answer is yes. As stated in the LOI, a hazardous material with a density which exceeds the\nmaximum lading density for the cargo tank indicated on the name plate may be loaded in to a\ncargo tank as long as the maximum weight of the lading marked on the specification plate is not\nexceeded. See § 173.24b(d)(2).\nI hope this information is helpful. Please contact us if we can be of further assistance.\nSincerely,\nT.

PRODUCT LOAD\" (weight).\nSeveral recent rejections have occurred at a terminal due to the product density (Phosphoric Acid - density = 14.15\nLbs./gal.) exceeding the \"MAX. PRODUCT WT. 13 LBS/GALS XX\" on the specification plate. The intended load net\nweights were below the \"MAX. PRODUCT LOAD 53,810 LBS.\" on the plate.

GALS\n1pslc\nA prior September 25, 1996 interpretation from Delmer Billings to McKenzie Tank Lines (attached) states \"A\nhazardous material with a density which exceeds the maximum lading density for the tank indicated on the\nspecification plate may be loaded into a cargo tank if the maximum weight of lading marked on the specification\nplate is not exceeded. See provision in 49 CFR 173.24b(d)(2).\". Neither 173.24b in general nor this specific\nprovision refer to the material density as a limiting factor for lading.\nWe seek confirmation that the prior interpretation letter includes tank trailers, that it is still valid, and that the\nspecification plate weight limit is the load limiting factor for liquid materials with densities higher than the stated\nmaximum density.\nI hope this sufficiently summarizes our inquiry. Please contact me if you require clarification. Thank you in\nadvance and | look forward to your response.\nSincerely,\nGap 8. Phillips\nGregory S.
