Product classification
HS code for PMMA resin: 3906.10
Acrylic polymers, poly(methyl methacrylate), in primary forms.
Classification of PMMA resin under HS 3906.10
Poly(methyl methacrylate) resin, or PMMA, is classified under HS code 3906.10. This classification falls under Chapter 39 (Plastics), specifically heading 3906, which encompasses acrylic polymers in primary forms. PMMA is a synthetic resin produced through the polymerization of methyl methacrylate monomers. The classification is determined by the chemical composition of the polymer; if the methyl methacrylate monomer units predominate by weight over any other single monomer unit, the resin is classified under 3906.10. Per Note 6 to Chapter 39, the term 'primary forms' applies only to materials in bulk shapes such as granules, pellets, powders, or liquids. PMMA is valued for its optical clarity and UV resistance, and in its resin form, it serves as the raw material for manufacturing acrylic sheets, automotive lenses, and medical devices. The classification process follows GRI 1, which prioritizes the terms of the headings and chapter notes, ensuring that acrylic polymers are distinguished from other plastic types like polyesters or vinyl polymers.

Codes often confused with 3906.10
Common mistake. PMMA resin is often confused with PMMA sheets, which are classified under 3920.51. The distinction lies in the physical form: 3906.10 is for raw material (primary forms), while 3920.51 is for semi-finished flat products. Another misclassification occurs with 3906.90, which is the 'other' category for acrylic polymers. If the resin is a copolymer where methyl methacrylate is not the predominant monomer, 3906.90 would be the correct code. Importers also occasionally use 3208.20 for acrylic solutions, but that code is reserved for paints and varnishes, not raw resins.
Top exporters and importers of HS 390610 (the code used for PMMA resin), 2025
In 2025, the largest exporter of HS 390610 (the code used for PMMA resin) in UN Comtrade data was South Korea, with 18% of world exports; the largest importer in UN Comtrade data was China, with 21% of world imports. Countries that did not report 2025 data are estimated from partner records, which can understate them.

How these figures are built
109 countries reported 2025 trade to UN Comtrade in HS 2022, and their own totals are used. Countries that did not report are estimated from what other countries recorded trading with them. Those estimates miss trade with other non-reporting countries, so they can be low, and a non-reporting country can rank higher than shown or be missing from the list. World totals add both and leave out trade between two non-reporting countries. Figures are in current US dollars; reported imports are mostly valued CIF and exports FOB, and exports include re-exports. The UN Comtrade links show the underlying records; they can also list a few reporters left out here (regional groups and older HS editions).
