What is HS 721310?
HS 721310 covers hot-rolled deformed steel bars and rods in irregularly wound coils, commonly referred to as wire rod rebar or coil rebar. The deformations – surface ribs or indentations – are rolled into the bar during production to enhance mechanical bonding with concrete, distinguishing this product from plain wire rod (HS 721391) for classification purposes.
End uses are concentrated in construction and civil infrastructure: reinforced concrete slabs, columns, foundations, and precast elements. The coil format offers a handling and processing advantage for downstream fabricators who cut and bend rebar to specification on-site or in rebar fabrication shops. It is a direct input into housing, bridges, tunnels, and industrial facilities globally.
When classifying, note that the deformed surface profile is the critical differentiator. Smooth rod in coils falls outside 721310. If the product is not in coils, standard straight deformed rebar classifies under heading 7214. Always confirm with the specific national tariff schedule, as some jurisdictions apply subheading splits based on carbon content or cross-sectional dimensions.
Top Sourcing Countries for Deformed Steel Rebar in Coils (Wire Rod Rebar)
Supply of HS 721310 is highly concentrated, with five origins accounting for the overwhelming majority of global export volumes.
- China (CN): The dominant global producer, with structurally advantaged cost positions derived from scale, integrated supply chains, and historically subsidised energy and raw material inputs. Chinese export volumes are the single largest swing factor in global rebar pricing. However, Chinese-origin product faces anti-dumping and countervailing duty measures in the US, EU, and numerous other markets, severely limiting access to premium destinations.
- Turkey (TR): A major electric arc furnace (EAF) producer with strong access to scrap steel from regional markets. Turkish rebar is cost-competitive and widely accepted in European, Middle Eastern, and African markets. Turkey's EAF route makes its cost structure more sensitive to scrap prices and electricity costs than blast furnace producers.
- India (IN): A growing exporter with both BF-BOF and EAF capacity. Indian producers are competitive on price and increasingly targeting Southeast Asian and African markets. Watch for evolving quality certification requirements when specifying Indian-origin material.
- Ukraine (UA): Pre-conflict, Ukraine was a significant low-cost exporter to the EU and MENA. Export capacity remains constrained by ongoing conflict and infrastructure damage, but Ukrainian-origin material continues to move through available logistics corridors.
- Russia (RU): Sanction regimes have redirected Russian rebar away from Western markets toward South and Southeast Asia, Africa, and the Middle East. Procurement teams in sanctioned-jurisdiction markets must conduct rigorous compliance screening before engaging Russian-origin supply chains.
Import Duty Rates and Trade Agreements
Duty exposure on HS 721310 varies significantly by destination and origin. Always verify current rates with the relevant customs authority, as trade remedy measures can change with limited notice.
In the United States, Chinese-origin rebar carries substantial anti-dumping (AD) and countervailing duties (CVD) on top of Section 232 steel tariffs, making direct Chinese-origin procurement economically non-viable for most US importers. The EU applies AD measures on Chinese rebar and monitors other origins under its Steel Safeguard framework, which imposes tariff-rate quotas on imports exceeding country-specific thresholds.
Free trade agreements can materially reduce MFN duty burdens. Importers in GCC countries benefit from preferential access for Turkish-origin goods under bilateral arrangements. ASEAN-origin product may qualify for reduced rates in several Asia-Pacific markets, though rules-of-origin compliance must be verified carefully given elevated transshipment risk in the region.
Always request binding tariff rulings for large procurement contracts and factor trade remedy exposure into landed cost modelling before committing to an origin.
Cost Drivers and Price Outlook
Rebar pricing under HS 721310 is driven by a layered set of feedstock, energy, and policy variables. As of March 2026, key signals include:
- Iron ore: Spot prices are up approximately 6.6% month-on-month, applying upward pressure on BF-BOF producer costs in China and India.
- Coking coal: Up 14.6% month-on-month – a significant input cost increase for integrated blast furnace producers. This narrows the cost advantage of BF-BOF routes relative to EAF producers like Turkey.
- Energy (crude oil): Brent and WTI both up approximately 7.4% over the prior month, increasing transport and production energy costs across the supply chain.
- Chinese export policy: Export rebate adjustments, production curbs, or demand stimulus in China can shift global rebar availability rapidly. Monitor Chinese policy announcements as a leading indicator.
- Scrap steel: Critical for Turkish and EAF-route producers. Regional scrap availability and pricing in Turkey and South Asia directly influences offer prices from those origins.
The current feedstock environment suggests near-term cost support for rebar prices globally. Procurement teams locking in forward volumes should factor rising input costs into price negotiations and consider indexed pricing mechanisms where possible.
Compliance and Sourcing Considerations
HS 721310 carries an elevated transshipment risk profile. To circumvent AD and CVD measures – particularly those targeting Chinese-origin rebar – material is frequently routed through intermediary countries in Southeast Asia (Vietnam, Malaysia, Thailand) and the Gulf before re-export to the US or EU. Customs authorities in these markets have increased origin verification scrutiny, and importers found to have received circumvented goods face retroactive duty liability regardless of declared origin.
Due diligence requirements should include: mill test certificates traceable to the producing facility, proof of substantial transformation in the declared origin country, and supply chain mapping at least two tiers deep. For US importers, CBP Enforce and Protect Act (EAPA) investigations have resulted in significant duty deposits on rebar shipments from multiple origins.
Russian-origin material requires sanctions compliance screening under OFAC, EU, and UK regimes. Do not rely solely on the bill of lading country of origin – verify the producing mill and any intermediate trading entities.
How to Source Deformed Steel Rebar in Coils (Wire Rod Rebar) Efficiently
Efficient procurement of HS 721310 requires integrating trade intelligence into your sourcing workflow, not just price comparison.
- Qualify origins against your destination market's duty schedule before issuing RFQs. A lower ex-works price from a sanctioned or AD-affected origin can result in a materially higher landed cost.
- Request mill certificates and origin documentation upfront. Do not accept generic certificates of origin. Verify the producing mill is listed on relevant approved supplier registers where applicable.
- Monitor feedstock price indices. Iron ore, coking coal, and scrap steel movements are leading indicators of where rebar offer prices are heading. Build price review clauses into contracts for orders exceeding 90 days.
- Assess transshipment flags in shipping documentation. Unusual routing through third countries, short transit times inconsistent with declared origin, or unfamiliar trading intermediaries are all red flags.
- Use trade data platforms to benchmark supplier volumes, verify declared origins, and identify alternative supply corridors before your current contract expires.
