Manufacturing & Production Terms
- OEM (Original Equipment Manufacturer): A factory that manufactures a product entirely according to the buyer’s custom specifications and designs.
- ODM (Original Design Manufacturer): A factory that has pre-designed products that buyers can purchase and rebrand (white-label) as their own with minimal modifications.
- MOQ (Minimum Order Quantity): The lowest number of units a factory is willing to produce or sell in a single order.
- Tech Pack: A detailed document containing all specifications for a product, including materials, dimensions, CAD drawings, and packaging requirements.
- Golden Sample: The final, approved prototype that serves as the benchmark for all subsequent mass production.
- Lead Time: The total time it takes from placing an order to having the goods finished and ready for shipment.
Quality Control & Compliance

- QC (Quality Control): The process of inspecting products to ensure they meet the agreed-upon standards before they are shipped.
- AQL (Acceptable Quality Limit): A statistical measurement used during inspections to determine the maximum number of defective units allowed in a batch before the entire order is rejected.
- PSI (Pre-Shipment Inspection): An inspection conducted when production is 80-100% complete, right before the goods are packed for shipping.
- NNN Agreement (Non-Disclosure, Non-Use, Non-Circumvention): A legally binding contract drafted for Chinese jurisdiction to protect a buyer’s intellectual property from being stolen or copied by the factory.
Shipping & Logistics (Incoterms)

- EXW (Ex Works): The buyer is responsible for all shipping costs and risks from the moment the goods leave the factory doors.
- FOB (Free on Board): The supplier pays for transportation to the port and loading the goods onto the ship. Once on the ship, the responsibility transfers to the buyer.
- CIF (Cost, Insurance, and Freight): The seller pays for the freight and insurance to deliver the goods to the buyer’s destination port.
- DDP (Delivered Duty Paid): The supplier handles everything—shipping, insurance, and import duties—delivering the goods directly to the buyer’s warehouse.
- Bill of Lading (B/L): A legal document issued by a carrier to a shipper that details the type, quantity, and destination of the goods being carried. It serves as a receipt of shipment.
Financial & Payment Terms
- T/T (Telegraphic Transfer): A standard international bank wire transfer, commonly used to pay Chinese suppliers (typically 30% upfront, 70% before shipment).
- L/C (Letter of Credit): A secure payment method where the buyer’s bank guarantees payment to the supplier once specific shipping documents are presented.
- PI (Proforma Invoice): A preliminary bill sent to buyers in advance of a shipment or delivery of goods, outlining the terms of the sale.
