Use Tares, TARIC, Explanatory Notes and decision rules for machines, electronics and vehicle parts. 19 September 2026 ## Quick answer Quick answer: To determine the HS code, first describe the spare part precisely (function, materials, weight), then narrow chapters and positions in the Harmonized System and Swiss Tares. Use Tares, EU TARIC, the HS Explanatory Notes and, if needed, a binding tariff decision (BTI/VZTA). ## 1. What is an HS code and why it matters The HS (Harmonized System) is the global classification for goods. It determines duties, controls and trade statistics. In Switzerland, Tares adds national subheadings. Correct classification affects customs, duties and compliance. ## 2. Step 1: Describe the part in detail Record name, function, main materials, dimensions, weight, electrical features and whether it is a replacement or a complete unit. Example: “12 V starter motor for commercial engine, copper windings, 3.2 kg.” ## 3. Step 2: Narrow by chapter and heading Scan HS chapter titles to limit options. Spare parts may fall under machinery/electrical chapters (84/85) or vehicles (87). Narrowing chapters makes it faster to find the correct code. ## 4. Step 3: Check if it is a part, accessory or complete device Some headings list parts or accessories. Decide if the item is classified as a component of a larger good or as a standalone product. This affects the selected subheading. ## 5. Step 4: Use Tares, TARIC and Explanatory Notes Use Switzerland’s Tares database for national headings. TARIC and the HS Explanatory Notes help interpret terms and examples. Watch for exclusions and special rules in the notes. ## 6. Step 5: Apply material and function rules For composite parts, determine the essential character by material, function or value. The Explanatory Notes explain which element governs classification. Keep documentation to justify your choice. ## Frequently asked questions When should I request a binding tariff decision? Request a binding decision (BTI/VZTA) when classification is uncertain or financial risk is high. It gives legal certainty from Swiss customs. Are HS codes the same across countries? HS headings are harmonized internationally, but countries add national subheadings. Use Tares for Swiss customs and TARIC for EU checks. How do I classify assembled spare parts? Identify the component that gives the assembly its essential character by function, material or value. Follow the HS rules and document your analysis. What documentation should accompany the classification? Provide technical datasheets, photos, material lists, supplier info and the suggested code. This helps customs and carriers process imports smoothly. ## Plan a courier trip in Switzerland x25pronto Switzerland carries small and well packed shipments by car.
