HS Codes for Fabricated Steel Parts: 7216 vs 7308 vs 7326 Explained

Published November 2026  ·  10 min read  ·  Buyer's Guide  ·  Trade & Customs

A drilled beam, a welded frame and a laser-cut bracket are all "steel parts". At the border, however, they can fall under three different HS headings. Each heading can have its own duty, quota, CBAM and origin rules. Buyers lose time and money when an invoice says one code, the customs broker picks another, and the CBAM report uses a third. This guide explains where sections, structures and other steel articles are classified, with practical examples and a quick classification helper.

Why the Right Code Matters More in 2026

Until recently, many fabricated steel parts were classified loosely because the duty difference was small. Three changes have raised the stakes:

• EU steel quotas: since 1 July 2026, many Chapter 72 and tube products are subject to quarterly quotas with a 50% out-of-quota duty. Most Chapter 73 articles are not. See the EU's new steel import regime.
• CBAM: the carbon border tax covers Chapter 72 and listed Chapter 73 headings, including 7308, 7318 and 7326. The CN code decides whether you must report and pay. See CBAM in 2026.
• Origin documents from Türkiye: steel products covered by the former ECSC Treaty are outside the EU–Türkiye customs union and need a preferential origin proof such as EUR.1. Most other industrial goods travel with an A.TR movement certificate. A wrong code can mean the wrong document and an unexpected duty.

How Steel Classification Works

The first six digits of a code are the international Harmonized System (HS). The EU adds two digits for the Combined Nomenclature (CN) and two more for TARIC. Classification follows the General Interpretative Rules (GIR). In practice, three of them do most of the work:

1. GIR 1: the wording of the headings and the section and chapter notes decide first.
2. GIR 3: when two headings could apply, the more specific description wins over the general one.
3. GIR 6: the same logic is then applied at subheading level.

The Explanatory Notes to the HS are not legally binding, but customs authorities rely on them heavily. Most of the distinctions below come from them.

The Main Headings for Steel Products and Parts

For the classification of raw materials such as coils, bars and tubes, see our main HS codes guide for steel imports.

7216 vs 7308: When Does a Section Become a Structure?

Heading 7216 covers sections that have been rolled or formed. The Explanatory Notes allow sections in 7216 to be drilled, punched or twisted, provided that they do not thereby take on the character of articles of other headings. Heading 7308 covers structures, parts of structures, and sections "prepared for use in structures".

Customs practice draws the line at added structural elements. For example, US Customs ruled in HQ 965792 that H-beams that were cut to length, coped, drilled and punched remained in heading 7216. Beams with plates, stiffeners or other structural elements bolted or welded onto them are "prepared for use in structures" and fall in 7308.

7308 vs 7326: Structure or "Other Article"?

Heading 7326 is the residual heading for articles of iron or steel that are not covered more specifically elsewhere. The Explanatory Notes describe structures in 7308 as products that, once put in position, generally stay in position. They are usually built from bars, sections, tubes and plates by welding, bolting or riveting.

• Platform gratings used as floors, walkways or stair treads in a structure are typically classified in 7308.
• Drainage grates for gullies and channels are usually not part of a structure. US Customs, for example, classified welded steel drain grates in 7326 (ruling H258806). Cast iron grates and manhole covers go to 7325.
• Brackets, clips, base plates and connectors sold separately are often classified in 7326, unless they are clearly identifiable as parts of a specific structure.

Laser-Cut, Bent and Machined Parts

Cut sheet and plate

Under the Chapter 72 notes, flat-rolled products cut to a shape other than rectangular or square stay in the flat-rolled headings (7208–7212), provided they do not take on the character of articles of other headings. A plain laser-cut blank can therefore still be a flat product. Once the blank is bent, punched for a specific function, or assembled, it becomes an article, usually in 7326.

Sheet metal components and enclosures

Bent, welded and painted sheet metal parts without a more specific heading go to 7326 90. Complete products often have their own headings, for example electrical enclosures and boxes in Chapter 85, or furniture in Chapter 94. See our sheet metal fabrication guide.

Machined parts and gears

Parts suitable solely or principally for a particular machine are classified as parts of that machine in Chapter 84, for example gears and shafts in 8483 or parts of cranes and excavators in 8431. However, "parts of general use", such as bolts, nuts, chains and springs, stay in their Chapter 73 headings even when made for a machine. See CNC machining and gear manufacturing and industrial fastener types.

Castings and forgings

Cast articles go to 7325, and forged or stamped articles not further worked go to 7326 19. Once a casting or forging is machined into a recognisable part of a machine, it normally moves to the parts heading of that machine.

Quick Classification Helper

This helper gives a first indication only, based on the general rules described above. Final classification depends on the full product description and the national tariff. Confirm it with your customs broker or apply for Binding Tariff Information.

Origin Documents for Steel from Türkiye

The ECSC product list is defined by product, not by chapter, so check each CN code. Agree the code before shipment, so that the invoice, the origin document, the customs declaration and the CBAM report all match.

Practical Tips for Buyers

• Agree the CN code on the proforma invoice, not only on the final invoice.
• Describe the goods precisely: material, shape, processing (cut, drilled, welded), coating and function. "Steel parts" is not enough for customs.
• Send drawings to your customs broker for fabricated items before the first shipment.
• Use Binding Tariff Information (BTI) for repeat products. An EU BTI is binding on all EU customs authorities for three years.
• Check quota, CBAM and anti-dumping measures for the exact code in TARIC before you sign the contract.
• Keep the classification consistent across invoice, origin document, customs declaration and CBAM report.

How Steeling.net Helps

Steeling.net sources sections, structures and fabricated parts from selected Turkish manufacturers. With each quotation we state the proposed HS code, the production processes and the origin document, so that your customs broker can confirm the classification before shipment. When we can, we deliver fabricated assemblies rather than raw sections. This can simplify logistics and, depending on the product, keep the goods outside the steel quota categories.
