BR 1208 Polybutadiene Rubber is described as 100% polybutadiene (CAS-9003-17-2) imported for use in manufacturing packings, shoe products, chemically blown sponge, oil field products, industrial and automotive molded parts. NBR 6240 Acrylonitrile-Butadiene Rubber is described as 100% acrylonitrile-butadiene copolymer (CAS-9003-18-3) imported for use in manufacturing packings, shoe products, chemically blown sponge, oil field products,…
H063639 · 2009-09-03 — Request for Binding Ruling; Classification; Factice/Synthetic Rubber
Insofar as those entries have already been liquidated under subheading 3812.10.5000, we will consider your letter as a request for a binding ruling. FACTS: The subject material, referred to as “Rhenopren C” (C.A.S. 68153-37-7), is described as being a factice made from sulfurized rape-seed oil ( a heavy unsaturated oil) which is used as a rubber replacement and processing aid for improving the form and handling of uncured rubber compounds. It is said to increase the resistance to deformation of uncured rubber. Rhenopren C factice consists of finely ground granules derived from refined…
N047737 · 2008-12-30 — The tariff classification of NISSO-PB-B2000 synthetic rubber from Japan.
You submitted dumbbell samples vulcanized with sulfur and prepared in accordance with ASTM D412-98a Test Method and MSDS sheets with information on the chemical composition.
