U.S. imports of iron & steel barbed wire and fencing wire (HS 731300) totaled $650K in August 2026, imported from 18 countries.
Importers of Iron & Steel Barbed Wire and Fencing Wire paid $344K in duties in August 2026, an effective tariff rate of 52.96% of the $650K imported — duty actually collected as a share of that value, not the published tariff schedule. Iron & Steel Barbed Wire and Fencing Wire imports of $650K in August 2026 ran 26% below the year-to-date monthly average of $881K.
Last updated: August 2026 dataBarbed wire, twisted hoop wire, single flat wire (barbed or plain), and loosely twisted double wire used for fencing — all of iron or steel — are classified here, with agricultural, border-security, and perimeter-fencing applications driving demand. Mexico is the leading US supplier, a position reinforced by geographic proximity and integrated North American steel fabrication networks, while China and Vietnam are also significant sources. This heading collapses to a single 10-digit line (7313000000), so classification disputes typically involve distinguishing fencing wire from woven wire fencing products (heading 7314) or from plain wire (heading 7217). Section 232 steel tariff treatment applies.

Barbed wire and twisted fencing wire (7313) consists of one or two strands twisted together, with or without barbs, and is not woven into a mesh or grid pattern. Woven wire fencing — where wires are interlaced at right angles or in a hexagonal pattern — falls under heading 7314. The distinction matters because the two headings carry different duty rates and may have different Section 232 treatment.
Beyond standard entry documentation (commercial invoice, packing list, bill of lading), importers should be prepared to provide a certificate of origin to support USMCA preferential treatment if applicable, a mill certificate confirming steel composition, and country-of-origin marking on the product or packaging. CBP may also request documentation to verify that the goods are not subject to any active antidumping or countervailing duty orders.
