Doors, windows and their frames and thresholds for doors

Subheading 7610 10 of the Combined Nomenclature covers doors, windows and their frames and thresholds of aluminium, commonly referred to as aluminium joinery or aluminium fenestration products. Heading 7610 covers structures and their parts of aluminium used in construction, and subheading 7610 10 identifies within that heading the elements of doors and windows, including complete frame sets, door and window leaves (sashes), thresholds, window frames, curtain walling and glazed systems with aluminium subframes. Aluminium joinery is manufactured from extruded profiles of 6000-series alloys (most commonly 6060-T5 or 6063-T5 per EN 755), fitted with thermal breaks (warm-edge systems), EPDM gaskets and hardware. This subheading covers both complete finished products and knock-down sets intended for on-site assembly, provided the tariff heading is appropriate for the set as a whole under GRI 2(a). The key classification criteria are the predominant material (aluminium) and the intended use (doors, windows, frames, thresholds). Distinction from subheading 7610 90 (other aluminium structural products for construction) requires an assessment of whether the products constitute elements of doors and windows or thresholds. For import purposes, the importer should hold a detailed product specification including technical documentation, applicable EN standards (e.g. EN 14351-1 for external windows and doors) and the building requirements applicable in the destination country.

From 1 January 2026, aluminium doors, windows and frames covered by subheading 7610 10 are fully subject to the CBAM mechanism under Regulation (EU) 2023/956. The CBAM obligation is particularly significant for this subheading given the intensity of imports of aluminium joinery from China and other Asian countries. The importer must hold authorised CBAM declarant status and submit quarterly CBAM declarations containing embedded emissions data in tonnes of CO2 per tonne of product for each shipment, separately accounting for primary and secondary aluminium in the production input. CBAM certificates must be purchased by 31 May of the following year at a price corresponding to EU ETS allowances. Additional TARIC Q-series codes must be indicated in the customs declaration. The importer must hold an EORI number and lodge a complete customs declaration. Required import documentation includes: a commercial invoice with product description, dimensions and technical specification, transport document (CMR, B/L or AWB), product technical documentation including any declaration of performance and CE marking, and proof of origin for preferential rates. Aluminium joinery intended for the EU market is subject to the Construction Products Regulation (CPR, 305/2011) and must carry CE marking with a declaration of performance (DoP) under EN 14351-1. Current duty rates should be verified in the EU TARIC database.

Aluminium joinery of subheading 7610 10 imported into the EU may be subject to anti-dumping measures applied by the European Commission, particularly with regard to imports from China, where production of aluminium extrusions and aluminium construction products is intensive. Importers are required to verify the current status of AD measures in the TARIC system for the specific CN code and exporting country code before each transaction - AD duty rates can significantly affect the total cost of import. Imports from Russia and Belarus are subject to EU sanctions restrictions. Preferential rates under EU FTAs (CETA with Canada, JEFTA with Japan, agreements with South Korea, the UK, Vietnam and Ukraine) can significantly reduce the duty burden, provided rules of origin are met and a valid proof of preferential origin is submitted. Importing aluminium joinery from third countries involves a combined fiscal burden comprising MFN or anti-dumping duty, CBAM certificates and VAT. Importers must also verify that the imported joinery meets EU and national construction standards (EN 14351-1, thermal performance regulations) and applicable building regulations in the country of destination. All applicable trade measures must be verified exclusively in the EU TARIC system.

Aluminium classified under CN code 7610 10 (aluminium doors, windows and frames) may be subject to the EU Carbon Border Adjustment Mechanism (CBAM). From 2026, importers of unwrought aluminium must purchase CBAM certificates corresponding to CO2 emissions in the production process. Additionally, aluminium products must comply with REACH Regulation requirements and may be subject to restrictions on hazardous substances. Customs authorities verify environmental documentation during clearance. Aluminium recycling is particularly significant as secondary aluminium uses 95% less energy than.
