Tractors are classified under HS Code 870193. Ensure the supplier provides a Clean Bill of Lading, Commercial Invoice, and Packing List. For countries with strict biosecurity (like Australia or the USA), the tractor must be steam-cleaned and free of soil to pass quarantine. If shipping to landlocked regions, confirm multimodal transport arrangements. Always clarify Incoterms; CIF (Cost, Insurance, and Freight) is common, but FOB (Free On Board) gives you more control over the shipping timeline and costs.
