Heading 3908

Polyamides in primary forms

3 declarable lines

Heading 3908 covers polyamides in primary forms: resins, granules, pellets, powders, flakes and similar unformed masses, before they are made into film, fiber or finished parts. It splits three ways: a line for the named polyamide types (nylon 6, 11, 12, 6,6, 6,9, 6,10 and 6,12), a duty-free line for one specified copolymer, and a residual line for all other polyamides and polyamide blends.

Products in this heading

  • Nylon 6 resin pellets for injection molding
  • Nylon 6,6 molding compound in granule form
  • Nylon 12 powder for coating or sintering
  • Nylon 11 granules for extrusion
  • Polyamide hot melt adhesive resin in pellet form
  • Reprocessed nylon resin in flake or pellet form
  • Polyamide copolymer resin in primary form

How to choose the right subheading

  • Identify the exact polyamide type: nylon 6, 11, 12, 6,6, 6,9, 6,10 or 6,12 falls in the named line; anything else goes to the residual line.
  • Check whether the product is the specified bis(4-amino-3-methylcyclohexyl)methane-isophthalic acid-laurolactam copolymer, which has its own free line.
  • Confirm the goods are in a primary form such as liquid, paste, powder, granule, flake or lump, not a semi-manufactured shape.
  • For blends or copolymers of polyamides, decide whether the named-type line applies or whether the residual line is the correct fit.
  • Check whether the goods are scrap or a finished plastics article, since both are excluded from this heading.

Often confused with

  • Nylon monofilament, rods and sticks

    Once the polyamide is drawn or shaped into a profile with any cross-section over 1 mm, it leaves the primary forms of 3908.

    Heading 3916
  • Nylon tubes, pipes and hoses

    Hollow extruded tubing is a finished plastics article, not a primary form.

    Heading 3917
  • Nylon film and sheet, noncellular and not reinforced

    Flat shapes of plastics are classified by form, not by the resin they came from.

    Heading 3920
  • Polyurethane and other amino-resins

    Polyurethanes are a separate resin family and are not polyamides.

    Heading 3909
  • Nylon waste, parings and scrap

    Scrap of plastics has its own heading even when the material is a polyamide.

Frequently asked questions

What is the HTS code for nylon 6 pellets?

Nylon 6 in primary form is classified under 3908.10.00.00, which carries a general (MFN) rate of 6.3%.

What is the duty on polyamide resin?

The named polyamide types under 3908.10.00.00 pay a general (MFN) rate of 6.3%. Other polyamides and blends fall under 3908.90.70.00 at a general (MFN) rate of 6.5%.

How do I classify a polyamide that is not nylon 6, 11, 12, 6,6, 6,9, 6,10 or 6,12?

It goes in the residual line 3908.90.70.00 at a general (MFN) rate of 6.5%, unless it is the specified copolymer of 3908.90.20.00, which is free.
