The Instruction Manual: Nomenclature for Diisocyanates TDI, MDI and Derivatives was written to assist those persons that manufacture, import, process, or distribute various forms of toluene diisocyanate (TDI), methylene diphenyl diisocyanate (MDI), and their derivatives. The manual is intended to help clarify the Toxic Substances Control Act (TSCA) Inventory listings for these substances, decrease the number of unnecessary premanufacture notices (PMN) that are submitted under TSCA, and encourage harmonization of terms. Note, however, that the manual is provided for guidance purposes only. Each reader is solely responsible to ensure compliance with the requirements set forth in TSCA and its regulations. EPA, working with the Chemical Abstracts Service (CAS) and the Diisocyanates Panel of the American Chemistry Council (formerly the Chemical Manufacturers Association), developed the uniform nomenclature scheme that forms the basis of the manual, which was published October 9, 1993, by the Chemical Manufacturers Association and Polyurethane Division of the Society of the Plastics Industry, Inc. To obtain the CD-ROM of the manual, please contact us at isofacts@americanchemistry.com.

Note that, because the manual was published in 1993, the contact information in it may not be current. Also, Part II of the Manual was written primarily to assist with a one-time opportunity EPA offered to participate in a simplified Inventory correction procedure to bring then-current listings into accordance with the nomenclature rules. The deadline for that opportunity was December 1, 1993 (any additional Inventory corrections must now use the regular EPA procedure). The Manual appendices that related to that one-time opportunity are not included on the CD-ROM. Nevertheless, the information in Part II may help readers to understand the nomenclature rules that are set out in Part I of the Manual.
