Products classified under HTS 2910.90.10.00
Butylene Oxide (1,2-Epoxybutane)
Butylene oxide is a three-membered ring epoxide compound (1,2-epoxybutane) classified under HTS 2910.90.10.00 as it fits the chapter definition for separate chemically defined organic epoxides with a three-membered ring. It is primarily used as a reactive intermediate in organic synthesis for producing glycol ethers and surfactants.
2-Methyloxirane (Isobutylene Oxide)
2-Methyloxirane, also known as isobutylene oxide, is a branched epoxide with a three-membered ring, directly matching HTS 2910.90.10.00 for butylene oxide specifications. It serves as a key intermediate in manufacturing pharmaceuticals and polymer additives.
Butylene Oxide Technical Grade 99%
Technical grade butylene oxide at 99% purity is a chemically defined epoxide with a three-membered ring, qualifying under HTS 2910.90.10.00 per chapter note (a) allowing minor impurities. Commonly used in industrial production of propylene glycol ethers.
1,2-Epoxy-2-Methylpropane
1,2-Epoxy-2-methylpropane is a specific butylene oxide isomer featuring the required three-membered epoxide ring, classified under HTS 2910.90.10.00. It functions as a versatile alkylating agent in fine chemical manufacturing.
Butylene Oxide with Stabilizer
Stabilized butylene oxide contains added preservatives necessary for transport while maintaining its identity as a chemically defined three-membered ring epoxide under HTS 2910.90.10.00 per chapter note (f). Used in polymer initiator production.
