From MFG Calcs data: Tanks, vessels, and gas cylinders

U.S. imports of tanks, vessels, and gas cylinders (headings 7309, 7310, 7311) came to $1.34B in 2025, with $301M in calculated duty: an effective duty of 22.4%, every duty included.

Effective duty in Sep 2026: 42.8%, against 33.3% in Sep 2025.

Largest sources in 2025: Mexico $267M at 10.0% effective duty; China $181M at 59.2% effective duty; Canada $177M at 9.6% effective duty; India $106M at 23.8% effective duty; South Korea $92.1M at 13.1% 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.
