Nylon-Type Polyamides (PA-6, -11, -12, -6,6, -6,9, -6,10, -6,12), Primary Forms imports of $43.8M in August 2026 ran 16% above the year-to-date monthly average of $37.7M.
Last updated: August 2026 dataNylon-type polyamides — covering PA-6, PA-6,6, PA-11, PA-12, and related grades — are among the most widely traded engineering thermoplastics, serving automotive under-hood components, industrial tubing, textile fibers, and food-contact packaging. All US imports under this heading are classified under a single 10-digit line (3908100000), so grade and viscosity distinctions are documented commercially rather than through tariff splits. Canada is the top supplier, with Germany and Slovenia also significant sources, reflecting integrated North American supply chains and European specialty-grade production.

Because 3908100000 covers all enumerated nylon types without further tariff subdivision, grade identification is handled through commercial invoices, technical data sheets, and manufacturer certificates rather than separate HTS codes. Customs brokers may request this documentation to confirm the product falls within the heading's scope rather than under a specialty polyamide line in 3908.90.
Automotive (fuel lines, air intake manifolds, connectors), industrial (gears, bearings, cable sheathing), and textile fiber production are the primary demand drivers. PA-11 and PA-12 grades, often sourced from specialty European producers, are particularly valued for flexible tubing and offshore oil-and-gas applications due to their chemical resistance.
