Products classified under HTS 2905.39.90.00
1,3-Propanediol
1,3-Propanediol is a colorless, viscous liquid diol with two hydroxyl groups on a three-carbon chain, classified under HTS 2905.39.90.00 as an acyclic diol other than ethylene glycol or glycerol. It is widely used as a monomer in polyester fiber production and as a solvent.
1,4-Butanediol
1,4-Butanediol (BDO) is an acyclic diol used primarily in polyurethane and spandex production, falling under HTS 2905.39.90.00 as a straight-chain diol other than the principal named diols. Its two terminal hydroxyl groups define its acyclic alcohol classification.
1,5-Pentanediol
1,5-Pentanediol is a linear five-carbon acyclic diol used in cosmetics, inks, and polymer synthesis, classified under HTS 2905.39.90.00. Its structure fits perfectly within the 'other acyclic diols' category excluding ethylene glycol and glycerol.
2-Methyl-1,3-Propanediol
2-Methyl-1,3-propanediol (MPDiol) is a branched acyclic diol used in polyester resins and coatings, classified under HTS 2905.39.90.00 as an 'other' diol. The methyl substitution maintains its acyclic alcohol character.
Neopentyl Glycol
Neopentyl glycol (2,2-dimethyl-1,3-propanediol) is a sterically hindered acyclic diol used in alkyd resins and plasticizers, falling under HTS 2905.39.90.00. Its gem-dimethyl structure provides hydrolysis resistance in coatings.
1,6-Hexanediol
1,6-Hexanediol is a long-chain acyclic diol used in polyurethane elastomers and acrylates, classified under HTS 2905.39.90.00. Its six-carbon chain provides flexibility in polymer applications.
Propylene Glycol Methyl Ether Diol
This ether-diol combines propylene glycol structure with methyl ether functionality, used as a coalescing aid in paints, under HTS 2905.39.90.00 as an acyclic diol derivative. The dual hydroxyl/ether nature fits the 'other' category.
Tripropylene Glycol
Tripropylene glycol is an acyclic triol oligomer used as a reactive diluent in polyurethanes and epoxy resins, falling under HTS 2905.39.90.00 as an 'other' acyclic alcohol derivative. Its propoxylated structure maintains diol-like reactivity.
1,2-Hexanediol
1,2-Hexanediol is an acyclic vicinal diol used as a preservative booster and humectant in cosmetics, classified under HTS 2905.39.90.00. Its adjacent hydroxyl groups provide antimicrobial synergy.
Diethylene Glycol
Diethylene glycol (DEG) is an acyclic diol formed by two ethylene glycol units linked by ether bonds, used as a building block in unsaturated polyester resins, classified under HTS 2905.39.90.00. Despite ether linkages, its primary diol nature prevails.
