Methyl Methacrylate Monomer (MMA)
Methyl methacrylate monomer (MMA) is a colorless, volatile liquid used as the primary building block for polymethyl methacrylate (PMMA) resins and cast acrylic sheets. As a pure ester of methacrylic acid, it falls under tariff item 2916.14.00, which covers esters of methacrylic acid in the Customs Tariff of Canada.

More Specific Codes
This product may fall under a more specific subheading:
Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If the product is an ester of acrylic acid rather than methacrylic acid
Acrylic acid esters are classified separately under 2916.13.00, and the two are not interchangeable.
If importing finished PMMA sheets or plates rather than the monomer
Once polymerized into acrylic sheets, the product moves to Chapter 39 (plastics).
If the product is a mixture of monomers or contains additives beyond stabilizers
Mixtures not meeting Chapter 29's purity requirements may fall under residual chemical products.

Import Tips & Compliance
• Ensure the MMA is stabilized (e.g
• with hydroquinone) to prevent polymerization during transport; unstabilized material may be rejected at the border
• Declare the exact purity and any additives, as Chapter 29 allows only stabilizers necessary for preservation or safety
• Verify whether your shipment qualifies for a free trade agreement (e.g
• USMCA) to potentially reduce or eliminate duty
Related Products under Tariff item 2916.14.00
2-(2-Ethoxyethoxy)ethyl Methacrylate
2-(2-Ethoxyethoxy)ethyl methacrylate is a methacrylic acid ester with a polyether side chain, offering high flexibility and low glass-transition temperature for soft-touch coatings and plasticizers. As an ester of methacrylic acid, it is classified under tariff item 2916.14.00, even though the alcohol moiety contains ether linkages.
2-Ethylhexyl Methacrylate
2-Ethylhexyl methacrylate is a branched-chain ester of methacrylic acid used in pressure-sensitive adhesives and elastomers. As a separate chemically defined organic compound, it falls under this tariff item covering all esters of methacrylic acid.
2-Hydroxyethyl Methacrylate
2-Hydroxyethyl methacrylate (HEMA) is a hydrophilic methacrylic ester essential for contact lenses, dental composites, and hydrogel coatings. The hydroxyl group provides water solubility and hydrogen bonding, but the product remains an ester of methacrylic acid under tariff item 2916.14.00.
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. It is a separate chemically defined ester of methacrylic acid, classified under this tariff item.
Benzyl Methacrylate
Benzyl methacrylate is an aromatic ester of methacrylic acid used in optical resins. Despite the aromatic benzyl group, it is classified under this tariff item as an ester of methacrylic acid, since the acid is acyclic and unsaturated.
Butyl Methacrylate
Butyl methacrylate is the butyl ester of methacrylic acid, used as a reactive diluent in radiation-curable coatings and printing inks. It is a separate chemically defined compound and falls under this tariff item as an ester of methacrylic acid.
