The Tariff Assistant works through the GRI rules on your specific product to reach the right tariff item — and can price the duty on it in the same conversation.
Import Tips & Compliance
• Confirm the powder is not in dispersion form (i.e
• suspended in a liquid), as that would be classified differently
• Provide evidence of coagulation and drying to show it is in primary form
• If used in coatings, declare the end use but classify based on the product

Extrusion-Grade PTFE Resin
Extrusion-grade polytetrafluoroethylene (PTFE) resin in granular primary form, engineered with controlled particle size distribution for ram extrusion into rods and profiles. This pure PTFE polymer, with monomer units exceeding 95% by weight, is classifiable under tariff item 3904.61.00 as polytetrafluoroethylene in primary forms.
High-Bulk Density PTFE
High-bulk-density polytetrafluoroethylene (PTFE) resin with engineered density (0.8+ g/cc) for automated molding processes. This pure, unfilled PTFE polymer in granular primary form meets the 95% monomer content rule, qualifying for tariff item 3904.61.00.
High-Purity PTFE Granules
Pharmaceutical-grade polytetrafluoroethylene (PTFE) granules with ultra-high purity (>99.9% PTFE), used in medical device molding. The product is in primary granular form and meets the strict 95% monomer content rule for named polymers, falling under tariff item 3904.61.00.
Low-Temperature PTFE Resin
Modified polytetrafluoroethylene (PTFE) resin with reduced sintering temperature for energy-efficient processing. Despite the modification, the polymer remains chemically unmodified PTFE, as the lower sintering temperature is achieved through physical or morphological changes, not chemical reaction. It is classifiable under tariff item 3904.61.00.
