From MFG Calcs data: Plastic semi-finished products

U.S. imports of plastic semi-finished products (headings 3916, 3917, 3920, 3921) came to $13.16B in 2025, with $1.29B in calculated duty: an effective duty of 9.8%, every duty included.

Effective duty in Sep 2026: 10.6%, against 13.0% in Sep 2025.

Largest sources in 2025: Canada $3.02B at 0.3% effective duty; Mexico $1.68B at 1.0% effective duty; China $984M at 47.4% effective duty; Germany $928M at 11.4% effective duty; South Korea $850M at 8.5% 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.
