Products classified under HTS 2905.39.10.00
1,3-Butylene Glycol
1,3-Butylene glycol (1,3-butanediol) is a chemically defined acyclic diol with two hydroxyl groups on a four-carbon chain. It falls under HTS 2905.39.10.00 as a specific butylene glycol isomer used in cosmetics and pharmaceuticals. This classification applies to pure forms without impurities altering its chemical definition.
1,4-Butylene Glycol
1,4-Butylene glycol (1,4-butanediol) is an acyclic diol serving as a solvent and chemical intermediate. Classified under HTS 2905.39.10.00 for its specific chemical structure as butylene glycol. Used in polyurethane production and humectants.
Cosmetic-Grade Butylene Glycol
Pharmaceutical/cosmetic-grade 1,3-butylene glycol with >99.5% purity for skincare formulations. Meets HTS 2905.39.10.00 as a separate chemically defined diol per Chapter 29 note (a). Stabilized only for transport safety.
Industrial 1,4-Butanediol
Technical-grade 1,4-butanediol for plasticizer and polymer synthesis, classified as butylene glycol under HTS 2905.39.10.00. Chemically defined acyclic diol meeting Chapter 29 purity standards.
Humectant Butylene Glycol USP
USP-grade butylene glycol used as humectant in pharmaceuticals and cosmetics. Falls under HTS 2905.39.10.00 as a pure acyclic diol without excluded additives.
2,3-Butylene Glycol
2,3-Butylene glycol, a less common diol isomer used in fermentation products and chiral synthesis. Classified under HTS 2905.39.10.00 as a chemically defined butylene glycol.
