U.S. imports of welded link chain of iron or steel (nesoi) (HS 731582) totaled $7.8M in August 2026, imported from 34 countries.
Importers of Welded Link Chain of Iron or Steel (NESOI) paid $4.7M in duties in August 2026, an effective tariff rate of 60.69% of the $7.8M imported — duty actually collected as a share of that value, not the published tariff schedule.
Last updated: August 2026 dataWelded link chain not elsewhere specified covers a broad range of general-purpose and industrial chains whose links are formed by welding, spanning both alloy steel and non-alloy (iron or ordinary steel) constructions. The US tariff schedule further subdivides by material — alloy versus non-alloy steel — and by link wire diameter relative to 10 mm, yielding six distinct 10-digit lines (7315821000 through 7315827000). China leads US imports, with Germany, Japan, and Sweden supplying higher-specification alloy grades used in lifting, conveying, and mining applications. Section 232 and, for Chinese-origin goods, Section 301 measures apply across this heading.

The 10 mm wire diameter cutoff is a hard tariff-line boundary within 7315.82. Chain with link wire diameter not over 10 mm and chain over 10 mm are assigned separate 10-digit HTS codes for both alloy steel and non-alloy steel variants. Importers should measure the wire cross-section of the link itself — not the overall chain width — to determine the correct line.
Alloy steel chain contains deliberate additions of elements such as manganese, chromium, nickel, or molybdenum above the thresholds defined in the HTS General Rules of Interpretation and Chapter 72 notes. Mill certificates showing chemical composition are the standard supporting document; without them, CBP may require laboratory analysis to confirm the steel grade and correct subheading.
