Product classification
HS code for ABS plastic: 3903.30
Styrene polymers, acrylonitrile-butadiene-styrene (ABS) copolymers, in primary forms.
Classification of ABS plastic under HS 3903.30
Acrylonitrile-butadiene-styrene (ABS) plastic is classified under HS code 390330 because the description explicitly identifies "Styrene polymers; acrylonitrile-butadiene-styrene (ABS) copolymers, in primary forms." This heading specifically targets ABS copolymers, distinguishing them from other styrene polymers. The term "primary forms" refers to the raw material state of the plastic, such as liquids, pastes, powders, granules, flakes, and similar bulk forms, before they are molded or processed into finished articles. This classification ensures that the raw polymeric material is correctly identified based on its chemical composition and physical state.

Codes often confused with 3903.30
Common mistake. Common misclassifications for ABS plastic in primary forms include confusion with other styrene polymers or finished plastic articles. HS code 390311 covers "Polystyrene, in primary forms," which is a homopolymer of styrene and distinct from the ABS copolymer. HS code 390390, "Other styrene polymers, in primary forms," is a residual category for styrene polymers not specifically enumerated; however, ABS is explicitly named in 390330, making it the more precise classification. Furthermore, a significant error can occur by classifying finished products made from ABS, such as plastic parts or components, under 390330. Finished articles of plastic are generally classified under Chapter 39, but in headings such as 392690 ("Other articles of plastics") or more specific headings depending on the article's function.
Top exporters and importers of HS 390330 (the code used for ABS plastic), 2025
In 2025, the largest exporter of HS 390330 (the code used for ABS plastic) in UN Comtrade data was South Korea, with 30% of world exports; the largest importer in UN Comtrade data was China, with 18% 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 390330, not only ABS plastic.

How these figures are built
109 countries reported 2025 trade to UN Comtrade in HS 2022, and their own totals are used. Countries marked * did not, so their figures add up what other countries recorded trading with them, and their exports are valued at buyers' CIF prices. 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. UN Comtrade records Taiwan as "Other Asia, not elsewhere specified". Saudi Arabia's exports under that code are left out: they are far too large to be trade with Taiwan, so mostly undisclosed partners. 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 ABS plastic
What is the HS code for ABS plastic?
The HS code for ABS plastic is 390330 (Styrene polymers; acrylonitrile-butadiene-styrene (ABS) copolymers, in primary forms). The HS code for acrylonitrile-butadiene-styrene (ABS) copolymers in primary forms is 390330.
How do I classify ABS plastic for customs?
ABS plastic is classified under HS code 390330 — Styrene polymers; acrylonitrile-butadiene-styrene (ABS) copolymers, in primary forms. This is a 6-digit subheading level code.
Does ABS filament for 3D printers fall under 390330?
Yes, ABS filament for 3D printers is considered a primary form (specifically, monofilament or rod) of ABS plastic and is therefore correctly classified under HS code 390330.
Which countries are the top exporters of ABS plastic (HS 390330)?
In 2025, the top exporters of HS 390330 (the code used for ABS plastic) in UN Comtrade data were South Korea ($1.7B, 30% of world exports), Taiwan (about $961M) and China ($594M). World exports came to about $5.8B, adding countries' reported figures and partner-based estimates for those that did not report (UN Comtrade data). Countries that did not report 2025 data are estimated from partner records, which can understate them.
Which countries are the top importers of ABS plastic (HS 390330)?
In 2025, the top importers of HS 390330 (the code used for ABS plastic) in UN Comtrade data were China ($1.2B, 18% of world imports), Vietnam (about $435M) and the United States ($416M). World imports came to about $6.5B, adding countries' reported figures and partner-based estimates for those that did not report (UN Comtrade data). Countries that did not report 2025 data are estimated from partner records, which can understate them.
Is the HS code for ABS plastic the same in all countries?
The base HS code 390330 for ABS plastic is internationally standardized for the first 6 digits across 200+ countries. Individual countries may add additional digits for national tariff lines and specific classifications.
What is the NCM code for ABS plastic in Brazil?
Brazil splits HS 390330 into 2 NCM codes, so the right one for ABS plastic depends on the product's details: 3903.30.10 (ABS copolymers with filler), 3903.30.20 (ABS copolymers without filler).
