CN code 960350 covers brushes specifically designed and manufactured as integral components of industrial machinery, production equipment, and technological installations. These are not household or handheld tools but precision components integrated into mechanical systems. The category includes roller brushes used in printing, cleaning, and polishing machines, disc brushes fitted to machine tools and grinders, as well as brush modules built into surface treatment lines for metals, wood, and plastics. Bristle materials are selected according to technical function, including steel wire, brass wire, nylon filaments, and natural fibre. These brushes must meet strict dimensional and durability standards because they operate at high rotational speeds or under significant mechanical loads. Classification under 960350 requires confirmation that the product is an integral subassembly of a machine rather than a standalone tool. Documentation from the original equipment manufacturer is essential to support the correct tariff heading.

Machine brushes classified under 960350 are used across a wide range of industries. In metallurgy, roller brushes remove scale and clean steel sheets after hot rolling. In the woodworking industry, disc and roller brushes sand, profile, and distress wood surfaces to give finished products their final texture. The electronics industry uses delicate copper and carbon fibre brushes to clean printed circuit boards. In printing machines, brushes dissipate static charges and clean printing cylinders. Roller brushes are essential in automated vehicle washing and drying lines, while carbon brushes serve as electrical contacts in motors and generators. Selecting the correct CN code requires analysis of the product's intended use, since carbon brushes forming part of an electric motor may be subject to different regulations compared to mechanical cleaning brushes. Importers and exporters should verify classification with reference to the product's technical specification and its relationship to the host machine.

When clearing goods classified under 960350, complete technical documentation confirming the product's use as a machine part must be provided. The key document is the manufacturer's specification identifying the host machine and the brush mounting method. The country of origin affects applicable duty rates and tariff preferences arising from trade agreements concluded by the European Union. Importers should verify whether the product is subject to safeguard measures, quantitative restrictions, or registration obligations under machinery safety regulations. Customs value is determined in accordance with the Union Customs Code, taking into account the transaction price plus transport and insurance costs to the first point of entry into the EU customs territory. Where there is doubt about tariff classification, applying for Binding Tariff Information ruling is recommended. Proper classification avoids the risk of underpayment or overpayment of import duties.

Subheading CN 9603 50 covers industrial machine brushes. 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.
