U.S. imports of zinc-plated or zinc-coated wire of iron or nonalloy steel (HS 721720) totaled $13.4M in April 2026, traded with 29 countries.
Importers of Zinc-Plated or Zinc-Coated Wire of Iron or Nonalloy Steel paid $5.2M in duties in April 2026 — an effective duty rate of 49% on $10.7M in dutiable value, based on actual customs collections rather than the published tariff schedule.
Last updated: April 2026 dataGalvanized steel wire — coated with zinc for corrosion resistance — is a widely traded industrial input used in fencing, armoring cables, agricultural applications, and construction tie wire. The US tariff schedule subdivides this heading by carbon content bracket and wire diameter across more than a dozen 10-digit lines, reflecting the commercial importance of these specifications to downstream processors. Mexico and Canada lead US import supply, with China and Vietnam also among the top sources; Chinese-origin zinc-coated wire may carry Section 301 exposure in addition to Section 232 obligations.
AI-written summary of the official U.S. Census Bureau trade figures on this page — verify before relying on it.
A mill test certificate (MTC) from the producing mill is the standard document, as it reports the chemical composition including carbon percentage. CBP may request the MTC to verify classification into the correct carbon-content bracket (under 0.25%, 0.25–0.6%, or 0.6% and above), so importers should obtain and retain MTCs for all shipments.
Potentially yes. Certain steel wire products from Vietnam have been subject to antidumping and circumvention investigations. Importers should check current Commerce Department order and scope ruling lists at the time of entry to determine whether the specific product and origin combination carries additional duty liability beyond Section 232.
