CN code 7308 90 of the Combined Nomenclature covers other structures and parts thereof of iron or steel not classified under codes 7308 10 through 7308 40. This is a residual heading encompassing a wide range of structural steel products including industrial halls, hangars, canopies, roof structures, elevated walkways, steel staircases, scaffolding, guard rails, lighting columns, support structures, loading ramps and other load-bearing steel elements. This heading represents one of the most frequently used classifications for prefabricated steel structures in international trade. Classification under CN 7308 90 requires the product to constitute a steel structure or identifiable structural element processed beyond the form of basic rolled products from Chapter 72. Profiles, plates and angles not fabricated into structural elements remain classified under Chapter 72. The Construction Products Regulation (CPR) No 305/2011 applies to steel structures placed on the EU market, requiring a Declaration of Performance and CE marking in accordance with EN 1090-1. Classification follows the General Rules for Interpretation, Rules 1 and 6.

Importing steel structures under CN code 7308 90 into the EU is governed by the Union Customs Code. Since 1 January 2026, products under heading 7308 fall within the scope of the CBAM mechanism under Regulation (EU) 2023/956, obliging importers to register as authorised CBAM declarants, submit quarterly embedded emissions declarations and purchase CBAM certificates. Construction steel structures must comply with CPR No 305/2011 and bear CE marking based on EN 1090-1. The execution class (EXC1-EXC4) depends on the consequence class and use category. Required import documents include a commercial invoice with detailed technical description, design and fabrication documentation, material certificates per EN 10204, CE Declaration of Performance, welding documentation (WPS, WPQR), NDT test reports and certificate of origin. Welding must conform to EN ISO 3834 and be performed by certified welders. Products must comply with REACH. Current MFN duty rates and trade measures should be verified in the TARIC database of the European Commission.

Steel structures under CN code 7308 90 may be subject to EU trade defence measures. Steel safeguard measures under the TRQ system may cover structures under heading 7308, with an additional 25 percent duty above the quarterly quota limit. Imports of steel structures from Russia and Belarus are prohibited under EU sanctions. Anti-dumping duties may apply to prefabricated steel structures from China - the current status and rate should be verified in TARIC. The EU market for prefabricated steel structures is significant, with major non-European suppliers from China, Turkey and India. Steel structures are a key component of industrial and logistics construction where the price-quality ratio of execution is decisive. Preferential rates under EU FTAs (CETA, EU-Japan, EU-Korea, EU-Vietnam) may reduce import costs subject to documented preferential origin. Total import cost includes customs value, conventional duty, AD and safeguard measures, CBAM obligations and VAT. Current trade measures are available in TARIC.

Products classified under CN code 7308 90 (other steel structures and parts) must comply with applicable EU technical standards. Depending on their intended use, these may include harmonised EN standards for construction products (CPR Regulation 305/2011), the Machinery Directive or the Pressure Equipment Directive (PED). Construction products require CE marking and a Declaration of Performance (DoP). Customs authorities verify compliance with technical requirements during clearance and may withhold release of goods where required documentation or certificates are missing.
