HS Code 3903.30 – Styrene polymers; acrylonitrile-butadiene-styrene (ABS) copolymers, in primary forms
HS code 3903.30 is the 6-digit subheading for styrene polymers, acrylonitrile-butadiene-styrene (ABS) copolymers, in primary forms. It is used for ABS pellets, high-impact ABS, flame-retardant ABS, UV-resistant ABS and electroplating grade ABS.
What HS 3903.30 covers
This code covers acrylonitrile-butadiene-styrene (ABS) copolymers in primary forms, such as pellets or granules. ABS is a widely traded engineering thermoplastic known for its excellent balance of toughness, rigidity, and impact resistance, making it suitable for a vast array of applications. Major petrochemical companies and polymer producers are significant exporters, supplying industries like automotive (e.g., interior trim), electronics (e.g., computer housings), consumer appliances (e.g., refrigerator liners), and construction. Key trade considerations include the fluctuating prices of its three monomers (acrylonitrile, butadiene, styrene), the increasing demand for lightweight and durable materials, and the development of specialized grades (e.g., flame-retardant, UV-resistant, electroplating grade) for specific high-performance requirements.

Codes often confused with 3903.30
Common mistake. Often confused with 390320 (SAN copolymers) if the butadiene component, which provides impact resistance, is not identified, or with 390319 (HIPS) due to similar applications but different chemical structures.
Top exporters and importers of HS code 390330, 2025
In 2025, the largest exporter of HS code 390330 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.

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).

What products fall under HS code 390330?
ABS pellets, high-impact ABS, flame-retardant ABS, UV-resistant ABS, electroplating grade ABS, transparent ABS, general-purpose ABS
What are common misclassifications for HS code 390330?
Often confused with 390320 (SAN copolymers) if the butadiene component, which provides impact resistance, is not identified, or with 390319 (HIPS) due to similar applications but different chemical structures.
Which countries are the top exporters of goods under HS code 390330?
In 2025, the top exporters of HS code 390330 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 goods under HS code 390330?
