https://www.taxtmi.com/caselaws?id=81958 Tetramethyl Tetraphenyl Trisiloxane was treated as a chemically well-defined organo-silicon compound because the Chief Chemist's reports and technical literature showed a fixed molecular formula. On that basis, it did not fall within Heading 3910.00 as silicones in primary forms, which are non-chemically defined products. The product was instead classifiable under Heading 2931.00 as an other organo-inorganic compound, so the exemption under Notification No. 345/86-Cus. was unavailable. The classification dispute was therefore resolved against the concession claim. en-us Wed, 29 Jul 1992 00:00:00 +0530 Wed, 29 Jun 2011 18:56:05 +0530 TaxTMI RSS Generator https://www.taxtmi.com/caselaws?id=81958 Tetramethyl Tetraphenyl Trisiloxane was treated as a chemically well-defined organo-silicon compound because the Chief Chemist's reports and technical literature showed a fixed molecular formula.
