Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If containing significant acrylic acid free monomer (>1%)
Acrylic acid itself (not ester) classifies under 2916.11; excess free acid may trigger reclassification.
If technical grade with 2-5% methanol or polymerization byproducts
Impurities exceeding Chapter 29 tolerance shift classification to chemical mixtures.
If pre-polymerized into low MW liquid acrylic resin
Partially polymerized acrylic polymers (>MW 1000) classify under Chapter 39 primary forms.

Import Tips & Compliance
• HPLC chromatogram required to confirm isobutyl vs n-butyl isomer ratio for correct 'other esters' statistical reporting
• Inhibit with 25 ppm phenothiazine for long-term storage; declare on commercial invoice
• Segregate from amines and oxidizing agents in containers to prevent unwanted reactions

n-Butyl Acrylate
n-Butyl acrylate is the butyl ester of acrylic acid, a clear, colorless liquid with a characteristic odor used primarily as a monomer in polymerization reactions. It falls under HTS 2916.12.50.30 as an ester of acrylic acid, specifically the butyl ester variant, meeting Chapter 29 requirements for separate chemically defined organic compounds. Commonly employed in producing acrylic polymers for coatings and adhesives.
2-Ethylhexyl Acrylate (Monomer Grade)
Industrial-grade 2-ethylhexyl acrylate, a branched-chain ester of acrylic acid used in low-Tg polymers for pressure-sensitive adhesives. Classified under HTS 2916.12.50.30 as 'other' acrylic acid esters excluding methyl, ethyl, and specific isomers, per the unsaturated acyclic monocarboxylic acid esters heading. Meets Chapter 29 purity standards for chemically defined compounds.
Butyl Acrylate Monomer (Stabilized, 99.5% Purity)
High-purity butyl acrylate stabilized with 10 ppm hydroquinone, packaged in 200L drums for industrial polymerization. Falls squarely under HTS 2916.12.50.30 as the specific butyl ester of acrylic acid, a chemically defined unsaturated acyclic monocarboxylic acid ester per Chapter 29 scope. Excluded from Chapter 38 as it meets separate compound purity criteria.
