Plastics Materials & Resins imports of $1.5B in July 2026 ran 16% above the year-to-date monthly average of $1.3B.
Last updated: July 2026 dataPlastics materials and resins — polyethylene, polypropylene, PVC, polystyrene, and engineering polymers among them — serve as primary inputs for virtually every US manufacturing sector, classified in HTS Chapter 39 by polymer chemistry and physical form. Duty treatment varies by polymer type and whether the material is in primary form (granules, powders, liquids) versus semi-fabricated shapes. Section 301 tariffs have affected imports of certain resins from China, making origin documentation and HTS precision critical for cost management.

'Primary forms' under HTS Chapter 39 refers to liquids, pastes, powders, granules, flakes, and similar undifferentiated bulk forms — as opposed to plates, rods, tubes, or other semi-fabricated shapes. The distinction is fundamental: primary-form resins are classified in headings 3901–3914, while fabricated forms move into later headings with different duty rates.
Many plastics resin HTS lines sourced from China are subject to Section 301 tariffs. The applicable list and rate tier depend on the specific 10-digit HTS code; importers should consult USTR's Section 301 product lists and verify current exclusion status, as exclusions have been granted and revoked on a rolling basis.
