Subheading 9607 11 of the Combined Nomenclature covers slide fasteners with teeth of base metals, commonly known as metal zippers. These are interlocking closure devices in which the interlocking elements — known as teeth or scoops — are made of base metals such as brass, aluminium or zinc alloy. They are widely used in garments, bags, leather goods, tents and textile articles. Classification under subheading 9607 11 requires distinction from subheading 9607 19, which covers slide fasteners with teeth of plastics, and from subheading 9607 20, which covers parts of slide fasteners. Metal teeth provide greater durability and load resistance compared to plastic alternatives, which is relevant to the product description in commercial invoices. Classification follows the General Rules for the Interpretation of the Combined Nomenclature, particularly Rules 1 and 6. In cases of doubt regarding material composition or mechanism, applying for Binding Tariff Information ruling is strongly recommended.

Importing slide fasteners with base metal teeth under subheading 9607 11 into the European Union requires compliance with the Union Customs Code (Regulation (EU) No 952/2013). The importer must hold an EORI number and submit a customs declaration with the correct CN code. Required documents include a commercial invoice specifying the material of the teeth, a transport document (CMR, B/L or AWB) and a product specification. Metal slide fasteners intended for consumer products may be subject to REACH requirements concerning chemical substances in base metal alloys, particularly nickel in articles intended for prolonged skin contact. For products intended for children, toy safety or child product safety regulations may apply. Current MFN duty rates should be verified in the European Commission's TARIC database.

MFN duty rates for goods under subheading 9607 11 should be verified in the European Commission's TARIC database, as they are subject to change. Preferential rates may be available under EU trade agreements, including CETA (Canada), the EU-Japan EPA, the EU-South Korea FTA, the EU-UK TCA, and the Generalised Scheme of Preferences (GSP) for developing countries. Preferential rates require compliance with rules of origin and presentation of a valid proof of origin. A significant share of metal slide fasteners originates from China — importers should check TARIC for any applicable anti-dumping or countervailing duties for that country of origin. Imports from Russia and Belarus may be subject to EU sanctions. VAT is applied at the domestic rate upon import. All current rates and trade measures must be verified in TARIC before each shipment.

Subheading CN 9607 11 covers slide fasteners metal teeth. When importing into the EU, verify applicable duty rates in TARIC, check CE marking requirements (if applicable), and prepare the required customs documentation. Tariff classification should be based on the General Rules of Interpretation (GIR) of the Combined Nomenclature. If classification is uncertain, applying for Binding Tariff Information (BTI) from the competent customs authority is recommended. Also verify whether the product is subject to import restrictions, sanctions, or licensing requirements.
