Incoterms are a set of standardized trade terms published by the International Chamber of Commerce that define the responsibilities of the seller and buyer for the delivery of goods under sales contracts. Some key Incoterms include EXW (seller's minimum responsibility), FCA (seller delivers to a carrier), CPT (seller pays for carriage to destination), and DDP (seller bears all costs and risks to deliver the goods to the destination). Incoterms help clarify important issues like timing and allocation of costs and risks for international commercial transactions.
