From MFG Calcs data: Steel pipe and tube

U.S. imports of steel pipe and tube (headings 7304, 7305, 7306) came to $6.93B in 2025, with $1.78B in calculated duty: an effective duty of 25.6%, every duty included.

Effective duty in Sep 2026: 44.3%, against 39.1% in Sep 2025.

Largest sources in 2025: South Korea $1.12B at 25.5% effective duty; Canada $902M at 20.6% effective duty; Mexico $652M at 23.2% effective duty; Germany $460M at 23.0% effective duty; Japan $400M at 20.1% 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.
