During the first technical discussion, the buyer and supplier should exchange:

• Product specifications and requirements
• Quality standards and testing methods
• Required purity, grade, and certifications
• Packaging, storage, and handling conditions
• MOQ, lead time, and delivery requirements
• Regulatory and compliance documentation
• COA/SDS and sample availability
• Traceability and batch-control information

This helps both sides confirm technical compatibility, quality expectations, and compliance requirements before proceeding.
