SITCSection 5
U.S. imports of other acrylic polymers, primary forms (n.e.s.) (SITC 57529) totaled $93.3M in April 2026, traded with 55 countries.
Importers of Other Acrylic Polymers, Primary Forms (N.E.S.) paid $5.7M in duties in April 2026 — an effective duty rate of 8.2% on $69.6M in dutiable value, based on actual customs collections rather than the published tariff schedule. Other Acrylic Polymers, Primary Forms (N.E.S.) imports of $93.3M in April 2026 ran 15% above the year-to-date monthly average of $81.4M.
Last updated: April 2026 dataAcrylic polymers other than polymethyl methacrylate in primary forms encompass a wide range of acrylate and methacrylate homopolymers and copolymers — including polyethyl acrylate, polybutyl acrylate, and acrylic acid copolymers — that serve as binders in water-based coatings, pressure-sensitive adhesives, textile finishing agents, and superabsorbent polymers. The N.E.S. designation means this heading captures the residual acrylic polymer universe after PMMA is excluded, making it a commercially diverse and high-volume category. Emulsion polymers (latex form) and solution polymers are both traded under this heading, and the physical form — aqueous dispersion vs. dry powder vs. solution — can affect both classification and logistics planning. Importers should verify that the polymer's principal monomer is an acrylic or methacrylic acid ester to support classification here rather than under vinyl or other polymer headings.

Acrylic polymers in aqueous dispersion (emulsion or latex form) are generally still classified as polymers in primary forms, as the 'primary forms' definition in most nomenclatures includes dispersions and emulsions. However, if the product has been formulated with significant non-polymer additives (thickeners, coalescents, biocides), it may shift classification toward a prepared coating or adhesive heading. The degree of formulation is the key classification variable.
The principal monomer identity is the determining factor: acrylic polymers are based on acrylic acid, methacrylic acid, or their esters, while vinyl polymers are based on vinyl acetate, vinyl chloride, or related vinyl monomers. For copolymers containing both acrylic and vinyl monomers, classification typically follows the monomer present in the greatest proportion by weight, though the specific nomenclature rules of the applicable schedule should be consulted.
