Last updated: September 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.

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.
