Dear Dr. Wang:

This is in response to your September 12, 2005, letter requesting clarification of the Hazardous Materials Regulations (HMR; 49 CFR Parts 100-185). Specifically, you request confirmation from this Office that a product that contains 1-4% triphenylphophate in combination with tert-butylated triphenylphosphates is neither a marine pollutant nor a severe marine pollutant and therefore, is not subject to the HMR.

Under § 173.22, it is the shipper’s responsibility to properly classify and describe a hazardous material. This Office does not normally perform that function. However,
based on the information submitted, it is the opinion of this Office that a triphenyl phosphate/tert-butylate triphenyl phosphates mixture containing 1% to 4% triphenyl phosphates is not a marine pollutant nor a severe marine pollutant according to Appendix B in § 172.101. Therefore, provided your product does not otherwise meet the definition of a hazardous material (§ 171.8), it is not subject to the HMR.
