Products classified under HTS 2914.40.10.00
Diacetone Alcohol (4-Hydroxy-4-methylpentan-2-one)
Diacetone alcohol is a colorless liquid ketone-alcohol compound used as a solvent in lacquers, paints, and varnishes. It falls under HTS 2914.40.10.00 as a specific ketone-alcohol with the chemical structure 4-hydroxy-4-methylpentan-2-one, fitting Chapter 29's scope for separate chemically defined organic compounds with oxygen functions.
Technical Grade Diacetone Alcohol 99% Pure
Technical grade diacetone alcohol at 99% purity serves as an industrial solvent for wood stains and synthetic resins. Classified under HTS 2914.40.10.00 as the specific chemically defined ketone-alcohol, containing minor impurities permitted by Chapter 29 note (a).
Diacetone Alcohol Solvent for Lacquer Thinners
High-purity diacetone alcohol used specifically in lacquer thinner formulations for automotive refinishing. HTS 2914.40.10.00 applies to this separate ketone-alcohol compound, distinguished from mixtures by its chemical definition.
Pharmaceutical Grade Diacetone Alcohol USP
USP-grade diacetone alcohol meets pharmaceutical standards for use in drug synthesis and extraction processes. Falls under HTS 2914.40.10.00 as the pure ketone-alcohol compound per Chapter 29 definitions, separate from formulated medicinals.
Stabilized Diacetone Alcohol with Antioxidant
Diacetone alcohol stabilized with <0.1% antioxidant for extended shelf life in industrial storage. Remains under HTS 2914.40.10.00 per Chapter 29 note (f) as stabilizer necessary for preservation does not change principal classification.
