U.S. imports of methacrylic acid and its salts (HS 291613) totaled $1.8M in April 2026, traded with 7 countries.
Importers of Methacrylic Acid and Its Salts paid $218K in duties in April 2026 — an effective duty rate of 12% on $1.8M in dutiable value, based on actual customs collections rather than the published tariff schedule. Methacrylic Acid and Its Salts imports of $1.8M in April 2026 ran 15% below the year-to-date monthly average of $2.1M.
Last updated: April 2026 dataMethacrylic acid is the precursor monomer for polymethyl methacrylate (PMMA) and a range of specialty methacrylate polymers used in optical applications, dental materials, and high-performance coatings. South Korea and Germany are the leading US import sources, with Japan also a significant supplier — all three countries host integrated methacrylate production chains tied to major chemical groups. Classified under a single 10-digit line (2916130000), the heading covers both the free acid and its salts, with classification of downstream esters (such as methyl methacrylate) falling instead under heading 2916.14.
AI-written summary of the official U.S. Census Bureau trade figures on this page — verify before relying on it.
Methacrylic acid and its salts are classified under 2916130000, while methyl methacrylate (MMA) — the methyl ester of methacrylic acid — falls under heading 2916.14. This distinction is commercially important because MMA is one of the most widely traded methacrylate derivatives and has its own tariff treatment. Importers must ensure the commercial invoice clearly identifies whether the product is the free acid, a salt, or an ester to avoid misclassification.
Pure methacrylic acid and its aqueous or solvent solutions are generally classified under 2916130000 provided the methacrylic acid is the commercially significant component. However, if the solution is a prepared mixture formulated for a specific end use (e.g., a coating formulation), it may be reclassified under a preparation heading in Chapter 32 or 38. A certificate of analysis and a clear statement of commercial purpose on the invoice help establish the correct classification.
