Products classified under HTS 2916.14.20.20
Methyl Methacrylate Monomer (MMA)
Pure methyl methacrylate (MMA) is a colorless, volatile liquid monomer classified under HTS 2916.14.2020 as an ester of methacrylic acid. It serves as the essential building block for producing polymethyl methacrylate (PMMA) plastics and resins. This chemically defined unsaturated acyclic monocarboxylic acid ester falls squarely within Chapter 29 heading 2916.
Stabilized Methyl Methacrylate for Transport
Methyl methacrylate containing minimal hydroquinone stabilizer (typically 10-100 ppm) to prevent polymerization during storage and shipping. Classified under HTS 2916.14.2020 per Chapter 29 note (f) as stabilizer necessary for preservation/transport. Remains a separate chemically defined compound despite added stabilizer.
High-Purity Methyl Methacrylate 99.9% Electronics Grade
Ultra-pure MMA monomer with 99.9% purity and <10 ppm moisture, used in optical lens and display manufacturing. Falls under HTS 2916.14.2020 as chemically defined methacrylic acid ester without excluded additives. Meets Chapter 29 requirements for separate organic compounds.
Industrial Methyl Methacrylate Bulk Drums
MMA monomer packaged in 440 lb steel drums with 25 ppm MEHQ inhibitor for industrial polymerization plants. HTS 2916.14.2020 classification as unsaturated acyclic monocarboxylic acid ester per Chapter 29 scope. Standard form for acrylic sheet/coating production.
Methyl Methacrylate Optical Grade for PMMA Lenses
Low-metal impurity MMA (<1 ppb Fe/Cu) specifically refined for cast acrylic sheet used in optical applications. Precisely classified under HTS 2916.14.2020 as pure methacrylic acid methyl ester. Meets stringent Chapter 29 chemical purity standards.
Methyl Methacrylate with 50 ppm Hydroquinone Inhibitor
Standard commercial MMA with precisely 50 ppm monomethyl ether hydroquinone (MEHQ) to maintain liquid state during global transport. HTS 2916.14.2020 per Chapter 29 note (f) allowance for transport stabilizers. Industry standard for resin manufacturers.
