Lead Time

Lead Time refers to the total time from the date the buyer places an order or signs a contract to the date the seller completes production, prepares the goods, and actually delivers them (usually referring to FOB at the port of shipment or EXW at the factory). In foreign trade, it directly affects the buyer's inventory planning, sales rhythm, and capital turnover, and is one of the core terms in quotations and contract negotiations. Usage scenarios include inquiry replies, proforma invoices, sales contracts, and shipment period provisions in letters of credit. Notes: 1) The starting point (e.g., after receiving advance payment or confirming samples) and the ending point (e.g., shipment date or arrival date) must be clearly defined; 2) Peak production seasons, raw material procurement, and holidays (such as Spring Festival and Christmas) may extend the lead time; 3) It is different from 'Shipment Date,' which is a specific date, whereas lead time is a time period; it is also different from 'Transit Time,' which only refers to the time spent on sea or air transportation. Therefore, foreign trade practitioners should precisely stipulate the lead time in contracts and allow for a buffer to avoid breach of contract.
