Incoterms
International Commercial Terms (Incoterms) clearly define responsibility allocation between buyers and suppliers throughout the shipping process. EXW (Ex Works) places maximum responsibility on the buyer, with the supplier making goods available at their facility. FOB (Free On Board) represents the most common term for China sourcing, transferring responsibility to the buyer once goods pass the ship's rail at the named port. CFR (Cost and Freight) requires the supplier to arrange and pay for main carriage to the destination port, while CIF (Cost, Insurance and Freight) adds insurance coverage during transit. For land shipments, DAP (Delivered At Place) requires the supplier to deliver goods to the named destination, cleared for import but not unloaded. Incoterm selection significantly impacts cost structure and risk allocation – FOB terms provide buyer control over main carriage and insurance, potentially reducing costs through negotiated freight rates. DDP (Delivered Duty Paid) offers maximum convenience but reduces cost transparency and control. Clearly specified Incoterms in purchase agreements prevent misunderstandings about cost responsibility and risk transfer points throughout the supply chain.
Pre-Production Inspection
Quality assurance begins before manufacturing commences through comprehensive pre-production verification.
