Product classification
HS code for Acrylic polymer: 3906.90
Acrylic polymers, (other than polymethyl methacrylate), in primary forms.
Classification of acrylic polymer under HS 3906.90
HS code 390690 is specifically designated for "Acrylic polymers; (other than polymethyl methacrylate), in primary forms." Chapter 39 of the Harmonized System covers plastics and articles thereof, with 3906 focusing on acrylic polymers. "Primary forms" refers to the raw, unprocessed state of the polymer, such as liquids, pastes, powders, granules, flakes, lumps, or similar bulk forms, ready for further manufacturing or processing. This classification is appropriate for acrylic polymers that are not polymethyl methacrylate (PMMA) and are presented in their initial, bulk state, serving as fundamental raw materials for various industries. It accurately distinguishes the raw polymer from finished articles made from it.

Codes often confused with 3906.90
Common mistake. Common misclassifications for acrylic polymers often involve distinguishing between specific types of acrylics and between raw polymers and finished products. HS code 390610 is specifically for "Polymethyl methacrylate" in primary forms. The distinction is crucial: if the polymer is PMMA, it falls under 390610; otherwise, if it's another acrylic polymer, 390690 applies. Confusion can also arise with other polymer types covered in Chapter 39, such as polyethylenes (3901) or vinyl polymers (3904), which are chemically distinct. Furthermore, it is important not to confuse raw acrylic polymers with finished articles made from them, such as 392059, which covers "Of acrylic polymers (excluding polymethyl methacrylate), plates, sheets, film, foil and strip." The latter refers to manufactured goods, not the primary polymer material.
Top exporters and importers of HS 390690 (the code used for acrylic polymer), 2025
In 2025, the largest exporter of HS 390690 (the code used for acrylic polymer) in UN Comtrade data was China, with 15% of world exports; the largest importer in UN Comtrade data was China, with 12% of world imports. Countries that did not report 2025 data are estimated from partner records, which can understate them.
Figures cover everything classified under HS 390690, not only acrylic polymer.

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).

Questions about acrylic polymer
What is the HS code for Acrylic polymer?
The HS code for Acrylic polymer is 390690 (Acrylic polymers; (other than polymethyl methacrylate), in primary forms). The HS code for Acrylic polymer, specifically those other than polymethyl methacrylate and in primary forms (e.g., granules, powders, liquids), is 390690.
How do I classify Acrylic polymer for customs?
Acrylic polymer is classified under HS code 390690 — Acrylic polymers; (other than polymethyl methacrylate), in primary forms. This is a 6-digit subheading level code.
What does "in primary forms" mean for HS classification?
"Primary forms" refers to the raw, unprocessed state of a polymer, such as liquids, pastes, powders, granules, flakes, lumps, or similar bulk forms. These are materials ready for further manufacturing or processing into finished articles, rather than being finished products themselves.
Which countries are the top exporters of acrylic polymer (HS 390690)?
