N018528 October 22, 2007 CLA-2-39:OT:RR:E:NC:SP:237 CATEGORY: Classification TARIFF NO.: 3911.90.9050 Mr. Mark D. Pinchok Trade Compliance Specialist Bayer Corporate and Business Services LLC 100 Bayer Road Pittsburgh, Pennsylvania 15205-9741 RE: The tariff classification of two cyclohexanone-formaldehyde based ketone copolymer resins from Germany. Dear Mr. Pinchok: In your letter dated October 15, 2007 you requested a tariff classification Desmophen 1145 is a cyclohexanone-formaldehyde based ketone copolymer resin consisting of cyclohexanone-formaldehyde polymer (CAS-25054-06-2), derived from the condensation of cyclohexanone CH2(CH2)4CO (a saturated, alicyclic ketone) with formaldehyde CH2O (a reactive aldehyde), trimethylolpropane polypropylene glycol ether polymer (CAS-25723-16-4), and castor oil (CAS-8001-79-4). The resin is primarily used with aromatic polyisocyanates for the production of two-component low solvent content coating compositions and joint sealants. It can also be used in casting resin applications. Desmophen 1150 is a cyclohexanone-formaldehyde based ketone copolymer resin consisting of cyclohexanone-formaldehyde polymer (CAS-25054-06-2), derived from the condensation of cyclohexanone CH2(CH2)4CO (a saturated, alicyclic ketone) with formaldehyde CH2O (a reactive aldehyde), and castor oil (CAS-8001-79-4). The resin is primarily used with aromatic polyisocyanates for the production of two-component low solvent content coating compositions and joint sealants. It can also be used in casting resin applications.
