The product is a liquid mixture of chemicals consisting by weight of the following: — 63 % of tetrahydro-1,1,2,3,3- pentamethylindane (THPMI; CAS RN 33704-59-5); and — 34 % of hexahydro-1,1,2,3,3- pentamethylindane (HHPMI; CAS RN 33704-60-8); and — 3 % of 1,1,2,3,3-pentamethylindane (PMI; CAS RN 1203-17-4). The mixture is obtained by catalytic hydrogenation of PMI (starting material). The products formed during the chemical reaction are THPMI (main product) and HHPMI (by-product). The mixture is
Classification is determined by general rules 1 and 6 for the interpretation of the Combined Nomenclature, Note 1(a) to Chapter 29 and the wording of CN codes 3824, 3824 99 and 3824 99 92. Due to the significant concentration of HHPMI, the product is a mixture that cannot be considered as a separate chemically defined organic compound consisting of one molecular species within the meaning of Note 1(a) to Chapter 29 (see the Harmonized System Explanatory Notes to Chapter 29, General, point (A), first paragraph). The mixture is therefore excluded from classification in Chapter 29. Consequently, the mixture is to be classified under CN code 3824 99 92 as other preparations of the chemical or allied industries, not elsewhere specified or included. Documented CN 2026 code: 38249992.
