The HS code (the FEACN or TN VED TS code) for polymeric methylene diphenyl isocyanate, also called " polymeric MDI" was set as 3909 30 000 0 "other amino-aldehyde resins", in accordance with Decision of the Eurasian Economic Commission No. 159 of 16 September 2014.
The chemical represents a compound with a non-defined chemical composition. It consists of a mixture of one or more methylene diphenylisocyanate isomers and homologues, a pre-polymer - a product the molecules of which are characterized by a repetition of one or more types of monomer units and a reactive functional group contributing to the transformation of the pre-polymer into a high polymer of different structure.
The chemical is used in the industrial manufacture of polyurethane foams, coatings, adhesives, elastomers, sealants, etc.
