HS Code 3904.61 – Halogenated olefin polymers; fluoro-polymers, polytetrafluoroethylene, in primary forms
HS code 3904.61 is the 6-digit subheading for halogenated olefin polymers, fluoro-polymers, polytetrafluoroethylene, in primary forms. It is used for PTFE granular resin, PTFE fine powder, PTFE aqueous dispersion, PTFE micropowder and PTFE pellets.
What HS 3904.61 covers
This specific HS code targets polytetrafluoroethylene (PTFE), commonly known by its brand name Teflon, in its primary, raw forms. PTFE is a high-performance fluoropolymer renowned for its exceptional non-stick properties, chemical inertness, high-temperature resistance, and low friction coefficient. These characteristics make it indispensable across a wide array of demanding applications, from industrial gaskets and seals to medical implants and aerospace components. Major importers are typically industrialized nations with advanced manufacturing sectors, including the United States, Germany, Japan, and China, which require high-performance materials for their specialized industries. Leading exporters are countries with sophisticated chemical production capabilities, such as the US, Japan, and European nations. Key aspects of trading PTFE include ensuring specific grades (e.g., granular, fine powder, dispersion) meet application requirements, and adhering to strict quality and safety standards. Its high value and specialized uses make it a critical, albeit niche, commodity in global trade.

Codes often confused with 3904.61
Common mistake. This code is specifically for PTFE. It can be confused with other fluoropolymers under 390469 if the specific "polytetrafluoroethylene" distinction is missed, or with other non-fluorinated halogenated polymers. The "PTFE" designation is critical.
Top exporters and importers of HS code 390461, 2025
In 2025, the largest exporter of HS code 390461 in UN Comtrade data was China, with 24% of world exports; the largest importer in UN Comtrade data was Germany, with 13% 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).
