A Contract Quality Guarantee Letter is a common ancillary document in foreign trade contracts, issued by the seller or manufacturer, promising that the supplied goods comply with the quality standards, specifications, and technical requirements stipulated in the contract. It usually serves as a contract annex or an independent guarantee letter and is valid for a certain period after delivery (e.g., 12 months). Usage scenarios include: export of large equipment, bulk commodity transactions, OEM manufacturing, etc. Buyers often require the seller to provide this document to protect their rights. Precautions: The scope of guarantee, period, inspection standards (e.g., ISO, ASTM), claim procedures, and liability limits should be clearly specified; it differs from a 'Quality Inspection Certificate,' which is a third-party inspection result of delivered goods, whereas the guarantee letter is the seller's promise for the future; compared with a 'Warranty Card,' the guarantee letter focuses more on contractual performance guarantee and may involve return, replacement, or compensation. The difference lies in: a quality guarantee letter is a unilateral promise, a quality inspection certificate is a factual proof, and a warranty card is an after-sales repair promise. Foreign trade practitioners must ensure the guarantee letter terms are consistent with the contract, avoid vague expressions, and pay attention to applicable law and dispute resolution clauses.
📝 Examples

(Note: Used for equipment export, specifying standards and period)
2. The buyer requires the seller to issue a Contract Quality Guarantee Letter, promising that if quality defects occur within 12 months, the seller will replace or refund free of charge. (Note: Used for bulk commodities, specifying claim methods)
