Pure ethyl methacrylate (CH2=C(CH3)COOCH2CH3) is a colorless liquid unsaturated acyclic monocarboxylic acid ester used primarily as a monomer in polymerization reactions. It falls under HTS 2916.14.2010 as a specific ester of methacrylic acid, chemically defined per Chapter 29 note (a). Stabilizers may be added for safety and transport without changing classification.

Import Tips
• 1
• Provide Certificate of Analysis confirming ≥98% purity as ethyl methacrylate to avoid reclassification; 2
• Include stabilizer disclosure (e.g
• MEHQ <0.01%) per Chapter 29 note (f); 3
• Ship in UN-approved drums due to polymerization hazard, avoiding bulk tankers
