2916.14.20/Methyl Methacrylate Monomer/China

Methyl Methacrylate Monomer from China

Methyl methacrylate (MMA) is the methyl ester of methacrylic acid, a clear, volatile liquid used primarily in the production of acrylic polymers and resins. It falls under HTS 2916.14.20 as an 'other' ester of methacrylic acid, being an unsaturated acyclic monocarboxylic acid derivative. This chemically defined organic compound is essential for manufacturing PMMA plastics like Plexiglas.

Import Tips

• Verify purity levels and provide certificate of analysis (COA) to confirm classification as chemically defined compound per Chapter 29 notes

• Ensure proper hazardous material documentation (UN 1247) for transport as flammable liquid; include stabilizer content details

• Avoid misclassification as polymer by confirming <99% polymerization; test samples if bulk shipments vary
