Financial security is paramount in foreign trade transactions. Common payment methods include Telegraphic Transfer (T/T), Letter of Credit (L/C), and Collection. T/T is simple but carries higher risk; for new clients, it is generally recommended to use a "30% deposit + balance before shipment / against copy of B/L" model to mitigate risk. L/C provides a bank credit guarantee and is highly secure, but involves complex procedures requiring strict term review to ensure document compliance. Collection (such as Documents against Payment, D/P) relies on the bank only as an intermediary without assuming payment liability, carrying higher risk; it should only be used when the buyer's credit is fully understood. Additionally, companies should actively utilize export credit insurance and other tools to hedge against buyer default risks.
