HS Code 3902.90 – Propylene, other olefin polymers; n.e.c. in heading no. 3902, in primary forms
HS code 3902.90 is the 6-digit subheading for propylene, other olefin polymers, n.e.c. in heading no. 3902, in primary forms. It is used for polybutene-1, poly(4-methyl-1-pentene), ethylene-propylene-diene monomer (EPDM) in primary forms, metallocene polyolefins and cyclic olefin copolymers (COC).
What HS 3902.90 covers
This 'not elsewhere specified' code encompasses a broad range of other olefin polymers beyond just propylene homopolymers or copolymers, in their raw, primary forms (pellets, powders). It's crucial for specialized applications where unique properties are required, often involving advanced chemical structures. Major chemical producers and petrochemical giants are key exporters, while manufacturers across various sectors (specialty films, adhesives, automotive components, electrical insulation, medical devices) are the primary importers. Key aspects include the diverse chemical structures, performance-driven applications, the need for precise material specifications for high-tech uses, and the continuous development of novel olefin polymers for niche markets.

Codes often confused with 3902.90
Common mistake. Often confused with 390210 (polypropylene homopolymers) or 390230 (propylene copolymers) if the specific 'other olefin' nature is not clearly identified, or even 3901 for ethylene polymers if the olefin type is misidentified.
Top exporters and importers of HS code 390290, 2025
In 2025, the largest exporter of HS code 390290 in UN Comtrade data was the United States, with 18% of world exports; the largest importer in UN Comtrade data was China, with 23% 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).

Key aspects include the diverse chemical structures, performance-driven applications, the need for precise material specifications for high-tech uses, and the continuous development of novel olefin polymers for niche markets.
What products fall under HS code 390290?
Polybutene-1, poly(4-methyl-1-pentene), ethylene-propylene-diene monomer (EPDM) in primary forms, metallocene polyolefins, cyclic olefin copolymers (COC), polyisobutylene, ultra-high molecular weight polyethylene (UHMWPE) in primary forms
What are common misclassifications for HS code 390290?
Often confused with 390210 (polypropylene homopolymers) or 390230 (propylene copolymers) if the specific 'other olefin' nature is not clearly identified, or even 3901 for ethylene polymers if the olefin type is misidentified.
Which countries are the top exporters of goods under HS code 390290?
In 2025, the top exporters of HS code 390290 in UN Comtrade data were the United States ($550M, 18% of world exports), Belgium ($305M) and Germany ($304M). World exports came to about $3.0B, 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 390290?
In 2025, the top importers of HS code 390290 in UN Comtrade data were China ($743M, 23% of world imports), Germany ($314M) and the United States ($176M). World imports came to about $3.3B, 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.
How is HS code 390290 structured?
HS code 390290 is a 6-digit subheading under the Harmonized System. The first 2 digits (39) identify the chapter, digits 3-4 (02) identify the heading, and digits 5-6 (90) specify the subheading. This code is standardized globally by the World Customs Organization.
What is the Brazil NCM code for HS code 390290?
In Brazil, HS code 390290 is NCM 3902.90.00. The last two digits are 00 because Brazil does not split this HS code further.
