Supplementary Agreement

A Supplementary Agreement is a written document executed by both parties after the signing of a foreign trade contract to address matters not covered in the original contract, amend clauses, or add new content. Its core purpose is to modify or supplement the original contract, not to replace it. Use cases include: price adjustments, changes in delivery schedules, modifications to payment terms, supplementary provisions on quality standards, and refinement of force majeure clauses. Precautions: 1. Must explicitly reference the original contract number and signing date to avoid ambiguity; 2. The supplementary agreement should state that in case of conflict with the original contract, the supplementary agreement shall prevail; 3. Must be signed and sealed by authorized representatives of both parties, with an effective date noted; 4. If major changes are involved, it is advisable to re-sign the contract rather than use a supplementary agreement. Difference from an 'Amendment': A supplementary agreement focuses on adding new content, while an amendment focuses on changing existing clauses, though in practice they are often used interchangeably. Difference from a 'Memorandum': A memorandum is usually not legally binding, whereas a supplementary agreement has the same legal effect as the original contract.
