Products classified under HTS 2914.12.00.00
Methyl Ethyl Ketone (MEK)
Butanone, commonly known as methyl ethyl ketone (MEK), is a colorless volatile liquid organic compound with the formula CH3C(O)CH2CH3. It falls under HTS 2914.12.00.00 as an acyclic ketone without other oxygen function, specifically named butanone. Primarily used as an industrial solvent for resins, gums, and coatings.
MEK 99.5% Technical Grade
High-purity technical grade methyl ethyl ketone at 99.5% concentration, supplied in industrial drums. Classified under HTS 2914.12.00.00 as pure butanone, an acyclic ketone without additional oxygen functions. Used in adhesive manufacturing and paint thinning.
Butanone ACS Reagent Grade
ACS-grade butanone meeting American Chemical Society standards for laboratory use, with impurities <0.5%. Falls under HTS 2914.12.00.00 as chemically defined acyclic ketone. Essential for analytical chemistry and extractions.
Methyl Ethyl Ketone Stabilized
Stabilized MEK with minimal anti-oxidant to prevent peroxide formation during storage. Classified HTS 2914.12.00.00 as butanone with stabilizer necessary for preservation per Chapter Note 6(f). Used in nitrocellulose lacquers.
Industrial MEK Solvent Drums
Bulk methyl ethyl ketone packaged in 55-gallon steel drums for industrial solvent applications. Pure butanone under HTS 2914.12.00.00 as acyclic ketone without other functions. Key solvent in printing inks.
MEK for Paint Thinner
High-evaporation rate MEK specifically marketed for paint thinning and cleanup. Remains HTS 2914.12.00.00 as pure butanone; end-use doesn't affect chemical classification. Used in automotive refinishing.
Distilled Recovery MEK
Recovered and redistilled methyl ethyl ketone from solvent recycling operations, meeting virgin specifications. Classified HTS 2914.12.00.00 as chemically defined butanone. Used in cost-effective adhesive production.
Pharma-Grade Butanone USP
USP/NF grade butanone meeting United States Pharmacopeia standards for pharmaceutical solvent use. Pure acyclic ketone under HTS 2914.12.00.00 without other oxygen functions. Used in drug extraction processes.
MEK Printing Ink Solvent
Special MEK grade low in water content (<0.05%) for flexographic printing inks. Classified as pure butanone HTS 2914.12.00.00. Provides fast drying in high-speed presses.
Anhydrous MEK Laboratory Grade
Water-free (<0.01%) anhydrous methyl ethyl ketone for moisture-sensitive reactions. HTS 2914.12.00.00 as pure acyclic butanone. Used in Grignard reagent preparations.
