Products classified under Tariff item 2916.14.00
2-Ethylhexyl Methacrylate
>- 2-Ethylhexyl methacrylate is a branched-chain ester of methacrylic acid, used in pressure-sensitive adhesives and elastomers. It is a separate chemically defined organic compound, and as an ester of methacrylic acid, it falls under tariff item 2916.14.00. The branched alkyl chain imparts flexibility and low glass transition temperature.
2-Hydroxyethyl Methacrylate (HEMA)
>- 2-Hydroxyethyl methacrylate (HEMA) is a functional monomer with both an ester and a hydroxyl group, used in hydrogels and contact lenses. As an ester of methacrylic acid, it is classified under tariff item 2916.14.00. The hydroxyl group does not alter its classification as a methacrylic acid ester.
Benzyl Methacrylate
>- Benzyl methacrylate is an aromatic ester of methacrylic acid, used in optical resins and coatings. It is a chemically defined organic compound and falls under tariff item 2916.14.00 as an ester of methacrylic acid. The aromatic ring provides high refractive index and hardness.
Butyl Methacrylate
>- Butyl methacrylate is the butyl ester of methacrylic acid, used as a reactive diluent in radiation-curable coatings and printing inks. As a separate chemically defined compound, it is classified under tariff item 2916.14.00. The butyl group provides flexibility and hydrophobicity.
Dicyclopentenyloxyethyl Methacrylate Monomer
>- Dicyclopentenyloxyethyl methacrylate is a chemically defined organic compound and an ester of methacrylic acid. It contains a bulky dicyclopentenyl group linked via an oxyethyl chain, which imparts low shrinkage and high adhesion in radiation-curable coatings. As a separate chemically defined ester, it falls under tariff item 2916.14.00.
Ethylene Glycol Dimethacrylate (EGDMA)
>- Ethylene glycol dimethacrylate (EGDMA) is a difunctional ester of methacrylic acid, used as a crosslinking monomer in resins. Although it has two methacrylate groups, it is still an ester of methacrylic acid and falls under tariff item 2916.14.00. It is a chemically defined organic compound.
Ethyl Methacrylate
>- Ethyl methacrylate is an ester of methacrylic acid, used in coatings, adhesives, and specialty resins. It is a separate chemically defined organic compound and falls under tariff item 2916.14.00. The ethyl group provides good balance of reactivity and flexibility.
Glycidyl Methacrylate
>- Glycidyl methacrylate (GMA) features an epoxide ring and a methacrylic acid ester group, used in powder coatings and composites. As an ester of methacrylic acid, it is classified under tariff item 2916.14.00. The epoxide group allows crosslinking reactions.
Industrial Grade Dicyclopentenyloxyethyl Methacrylate (DCPMA-IG)
>- Industrial grade dicyclopentenyloxyethyl methacrylate is a lower-purity version of the methacrylic acid ester, but it still qualifies as a chemically defined organic compound under Chapter 29. The presence of impurities does not exclude it from heading 2916 as long as it is not rendered particularly suitable for a specific use. It is used in bulk resin production for adhesives and coatings.
Isobornyl Methacrylate
>- Isobornyl methacrylate is an ester of methacrylic acid with a cyclic isoborneol group, used in UV-curable coatings and dental composites. As a chemically defined organic compound, it falls under tariff item 2916.14.00. The bulky cyclic group provides hardness and low shrinkage.
Lauryl Methacrylate
>- Lauryl methacrylate is a C12 alkyl chain ester of methacrylic acid, used in comb polymers and lubricant additives. As a separate chemically defined compound, it is classified under tariff item 2916.14.00. The long alkyl chain reduces volatility and provides hydrophobicity.
Methyl Methacrylate Monomer
>- Methyl methacrylate (MMA) is the methyl ester of methacrylic acid, a clear, volatile liquid used primarily in the production of acrylic polymers and resins. As a separate chemically defined compound, it falls under tariff item 2916.14.00. It is the most common methacrylic acid ester.
n-Butyl Methacrylate
>- n-Butyl methacrylate is the straight-chain butyl ester of methacrylic acid, used in low-odor architectural paints and clear coats. As a chemically defined organic compound, it is classified under tariff item 2916.14.00. The n-butyl group provides good flexibility and weatherability.
Purified Dicyclopentenyloxyethyl Methacrylate (DCPMA)
>- Purified dicyclopentenyloxyethyl methacrylate (CAS 79752-12-0) is a high-purity ester of methacrylic acid, used in radiation-curable inks and adhesives. Its reactive double bond and bulky dicyclopentenyl group provide low shrinkage and good adhesion. As a separate chemically defined compound, it is classified under tariff item 2916.14.00.
Stabilized Dicyclopentenyloxyethyl Methacrylate Resin Precursor
>- Stabilized dicyclopentenyloxyethyl methacrylate contains MEHQ inhibitor to prevent polymerization during transport. Chapter 29 note (f) permits added stabilizers necessary for preservation or transport, so the product remains classified as an ester of methacrylic acid under tariff item 2916.14.00. It is used as a resin precursor in UV-curable systems.
