This reduces rework, customs holds and unexpected charges. ## Why correct HS classification matters The HS code affects duties, statistics and import rules. Misclassification can delay shipments and cause extra costs. Swiss importers in Zurich, Basel or Geneva should aim for traceable and defendable classifications. ## Prepare: collect data and technical details Start with a precise part description: commercial name, material, dimensions, net weight, function, OEM and use case. Add photos and exploded drawings. The clearer the data, the easier the match to tariff headings. ## Hands‑on method to find the HS code 1) Define the part by function (e.g. "brake pad", "spark plug", "hydraulic pump"). 2) Check HS chapters—chapters 84–90 often cover machines and parts. 3) Narrow by material and manufacturing stage. 4) Compare with existing customs documents, supplier data or similar product entries. ## Official Swiss sources and tools Use the Swiss TARES tariff database for codes and preferences. The World Customs Organization provides HS nomenclature and explanatory notes. For EU cross‑checks, TARIC can help. The Federal Customs Administration (FCA) publishes guidance and forms. ## Requesting binding tariff information (BTI) If classification remains unclear, request a BTI from the Swiss customs authority. A BTI provides legal certainty for imports. Submit technical specs, photos and a clear product description. Expect lead time—prepare for weeks rather than days. ## Practical notes for vehicle and machine parts Watch for: - interchangeable vs new parts: treatment can differ. - electronic modules: often fall in chapter 85. - small metal items: screws, bearings and pins have specific headings. Keep a rationale for your choice in your internal records for audits. ## Frequently asked questions Which matters more, material or function? Check whether the part is defined mainly by material or by its function. For example, a rubber hose is classed by material/use, while an assembled hydraulic unit is classed by function. Use chapter notes to guide the decision. How much does a BTI cost? BTI fees are set by the Swiss customs authority and depend on processing. Check the Federal Customs Administration website for current fee details and submission rules. Can my supplier give the HS code? Suppliers may provide a suggested code. The importer in Switzerland remains legally responsible for customs declarations. Verify any supplier suggestion against your technical data. What if customs disputes our classification? Provide documentation and technical data supporting your choice. If needed, apply for a BTI or consult a customs specialist. Early clarification limits delays and extra costs. ## Plan a courier trip in Switzerland x25pronto Switzerland carries small and well packed shipments by car.
