CN code 730110 of the Combined Nomenclature covers sheet piling of iron or steel, whether or not drilled, punched or made from assembled elements. Sheet piles are interlocking steel profiles driven into the ground to form a continuous barrier against water or earth pressure. They are used extensively in hydraulic engineering, port construction, flood defences, deep excavations, retaining walls and coastal protection structures. Sheet piles are produced as hot-rolled U, Z or omega profiles with interlocking joints (clutches) that ensure watertight connections between adjacent piles. The base material is structural steel of enhanced strength, typically grades S240GP, S270GP, S320GP or S390GP in accordance with EN 10248. Classification under subheading 730110 is distinguished from welded angles and shapes (730120) by the presence of interlocking joints designed for forming continuous walls. From steel profiles of Chapter 72, sheet piles are distinguished by their advanced degree of processing and specific constructional purpose. Correct classification requires analysis of the cross-section profile and the interlocking mechanism.

Importing steel sheet piling under CN code 730110 into the European Union is subject to the Union Customs Code (Regulation (EU) No 952/2013). As iron and steel articles under Chapter 73, sheet piles may fall under the CBAM (Carbon Border Adjustment Mechanism) from 1 January 2026 as defined in Annex I of Regulation (EU) 2023/956. Importers must verify whether subheading 730110 is covered by the obligation to report embedded emissions and purchase CBAM certificates. Required documentation includes a commercial invoice with technical specifications (profile type, steel grade, lengths, weight), material certificate EN 10204 type 3.1 with chemical analysis and mechanical properties, transport document and certificate of origin. Sheet piles must comply with EN 10248 (hot-rolled profiles) or EN 10249 (cold-formed profiles). Products intended for load-bearing construction are subject to CPR Regulation (EU) No 305/2011 and require CE marking with a Declaration of Performance (DoP) in accordance with harmonised standard EN 10248.

Steel sheet piling classified under CN code 730110 is subject to EU safeguard measures on steel products, operating as tariff rate quotas (TRQ) with an additional 25% duty above the quota. Importers should verify in the TARIC database which product category applies to subheading 730110 and the current quarterly quota utilisation level. Anti-dumping duties (AD) may apply to sheet piling from China, India or Turkey - the current status and rates should be checked in TARIC for the specific code and country of origin combination. Imports of steel products from Russia and Belarus are subject to prohibitions under EU sanctions packages. Preferential rates may be available under EU free trade agreements such as CETA (Canada), EU-Japan EPA or the EU-Korea FTA, provided rules of origin are met and a valid EUR.1 certificate, invoice declaration or REX entry is presented. Total import costs include MFN duty, any AD/CVD duties, safeguard duty, CBAM charges and VAT. All current trade measures should be verified in TARIC.

Products classified under CN code 7301 10 (sheet piling of iron or steel) 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.
