From MFG Calcs data: Plastics in primary forms

U.S. imports of plastics in primary forms (headings 3901, 3902, 3903, 3904, 3906, 3907, 3908) came to $12.49B in 2025, with $674M in calculated duty: an effective duty of 5.4%, every duty included.

Effective duty in Sep 2026: 7.6%, against 7.5% in Sep 2025.

Largest sources in 2025: Canada $4.15B at 0.3% effective duty; South Korea $1.51B at 5.1% effective duty; Mexico $1.17B at 0.3% effective duty; Germany $921M at 8.4% effective duty; Japan $863M at 7.9% effective duty.

These are family totals from U.S. import statistics published through USITC DataWeb, not this heading's rate alone; effective duty is calculated duty as a share of customs value, an estimate, not a ruling.

About these rates

The rates are those printed in the 2026 HTS Revision 23, published by the U.S. International Trade Commission. A 10-digit statistical line takes the rates printed on the 8-digit line above it. Chapter 99 duties (Section 232, Section 301, IEEPA) depend on the product, the origin and the date, are charged on top, and are not included. A code here is a strong lead, not a ruling: confirm it with a customs broker or a CBP binding ruling.
