From MFG Calcs data: Springs, chain, and wire mesh

U.S. imports of springs, chain, and wire mesh (headings 7314, 7315, 7320) came to $2.27B in 2025, with $699M in calculated duty: an effective duty of 30.8%, every duty included.

Effective duty in Sep 2026: 33.8%, against 42.2% in Sep 2025.

Largest sources in 2025: Mexico $801M at 18.8% effective duty; China $398M at 63.8% effective duty; Germany $188M at 30.8% effective duty; Japan $186M at 28.3% effective duty; Canada $178M at 21.2% 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.
