HS Codes for Steel Imports: A Buyer's Guide to Metal Trade Classifications

Published August 2026  ·  9 min read  ·  Import & Trade

Every tonne of steel that crosses an international border is classified by a Harmonised System (HS) code — a six-digit number that determines the applicable customs duty, anti-dumping measure, and import licence requirement at the destination. Using the wrong HS code is not a paperwork error; it is a customs offence that can result in delayed shipments, retroactive duty assessments, penalties, and in some jurisdictions, seizure of goods. This guide covers the most commonly used HS codes for steel and metal imports, explains the classification logic, and shows buyers how to verify the correct code before placing an order.

HS codes for steel and metal products are structured under Chapters 72 (iron and steel) and 73 (articles of iron or steel) of the Harmonised System, maintained by the World Customs Organization. Chapter 72 covers raw materials and semi-finished forms — ingots, flat-rolled products, bars, rods, profiles, wire, and tube. Chapter 73 covers manufactured articles — structures, tanks, wire products, fasteners, springs, and other fabricated steel items. The distinction between Chapter 72 and Chapter 73 is fundamental: the same steel in coil form (Chapter 72) and laser-cut to a finished part (Chapter 73) carries a different HS code, different duty rate, and potentially different anti-dumping status.

How the HS Code Structure Works for Steel

An HS code is built from left to right in increasing specificity. The first two digits identify the chapter (72 = iron and steel; 73 = articles of iron or steel). The next two digits identify the heading within that chapter (e.g., 7208 = flat-rolled products of iron or non-alloy steel, width ≥600mm, hot-rolled). The final two digits of the six-digit international code identify the subheading. Most countries then add two to four further digits for national tariff purposes, giving an eight or ten-digit commodity code used in customs declarations.

Chapter 72: Iron and Steel — Key HS Codes for Buyers

Chapter 72 covers primary steel products: flat-rolled coil and sheet, long products (bars, rods, wire rod), structural sections (beams, angles, channels), and tube and pipe. The classification within Chapter 72 depends on four variables: alloy content (non-alloy, stainless, or other alloy steel), product form (flat-rolled, long, hollow), width or diameter, and whether the product is hot-rolled, cold-rolled, or coated. Misclassifying between non-alloy and alloy steel, or between coated and uncoated flat products, is a frequent source of customs errors.

Long products (bars, rods, sections, wire)

Tube and pipe

Chapter 73: Articles of Iron or Steel — Key HS Codes

Chapter 73 covers manufactured and fabricated steel articles — products that have been processed beyond the primary forms of Chapter 72. Once steel is cut to shape, welded into a structure, formed into a fitting, or assembled into a component, it typically falls under Chapter 73 rather than Chapter 72. This chapter distinction matters significantly for anti-dumping duty purposes: a laser-cut steel blank may be classified under Chapter 73 and exempt from anti-dumping duties that apply to the equivalent uncut coil under Chapter 72.

HS Codes for the Most Common Steeling.net Product Categories

For buyers sourcing steel and metal products from Turkish manufacturers, the table below maps the most commonly ordered product categories to their typical HS heading. Note that the correct subheading — and the applicable duty rate — depends on additional variables such as alloy content, thickness, processing state, and end use. Always verify with a licensed customs agent or via your country’s tariff database before declaration.

How to Verify the Correct HS Code Before Importing

Verifying the correct HS code before placing a steel import order takes four steps: checking the product description against the official tariff schedule, consulting the explanatory notes for the relevant heading, using your country’s tariff lookup tool to confirm the duty rate, and — for high-value or recurring shipments — obtaining a binding tariff information (BTI) ruling that provides legal certainty. Self-classifying without these steps is the most common cause of customs penalties in steel imports.

1. Start with the product’s physical description. Identify the material (iron, non-alloy steel, stainless steel, alloy steel), the form (flat-rolled, bar, section, tube, fabricated article), and the processing state (hot-rolled, cold-rolled, coated, machined, welded). These three variables determine the chapter and heading.
2. Check the official tariff schedule for your import country. Use the EU’s TARIC database (ec.europa.eu/taxation_customs/dds2/taric) for EU imports, the UK Global Tariff tool for UK imports, or the USITC HTS database (hts.usitc.gov) for US imports. Search by product description or navigate the chapter structure.
3. Read the heading’s explanatory notes. The WCO publishes Explanatory Notes for each HS heading that clarify what is and is not included. These notes resolve most classification ambiguities. They are available through the WCO website and most national customs authority portals.
4. Check for anti-dumping measures on your specific code and origin. For EU imports, check TARIC for any additional duties, safeguard measures, or anti-dumping regulations linked to the specific subheading and country of origin. The same product from Turkey and from China may carry different duty rates on the same HS code.
5. Request a Binding Tariff Information (BTI) ruling for recurring imports. A BTI is a legally binding classification decision issued by your customs authority that gives certainty for three to five years. For high-volume steel imports where the duty rate difference between two plausible headings is significant, a BTI eliminates reclassification risk.

Turkey’s Customs Union and HS Classification for EU Buyers

Turkey operates within the EU Customs Union for industrial goods under Decision 1/95 of the EU–Turkey Association Council. This means that Turkish industrial goods — including most steel and metal products — benefit from zero customs duty when imported into EU member states, provided they are accompanied by an A.TR movement certificate confirming the goods are in free circulation in Turkey. Anti-dumping duties are applied separately from customs duties and are not covered by the Customs Union; buyers must check TARIC for any anti-dumping measures applicable to their specific HS subheading and product type even when importing from Turkey.

HS Classification Support for Buyers Sourcing from Turkey

Steeling.net provides buyers with the HS heading and export commodity code for all products quoted, as part of the standard supply proposal. For fabricated parts, processed components, and mixed orders covering multiple product types, our team coordinates with the Turkish manufacturer to ensure export documentation — including the commercial invoice, packing list, A.TR certificate, and EUR.1 where applicable — references the correct HS codes for both Turkish export and EU import declaration. Buyers are always advised to verify the applicable import duty and anti-dumping status with their own customs agent before placing an order.
