Before finalising an order for 2,4-Dihydroxy-6,7-Dimethoxy Quinazoline with Shanghai Extd Sci And Tech Co., Ltd, obtain a detailed quotation that breaks down the price per kilogram, packaging costs, and the chosen shipping term. Verify the supplier's ability to provide a full set of export documents, including a Certificate of Analysis, MSDS, and a commercial invoice that accurately describes the chemical for customs clearance.
Discuss and agree upon the production lead time and payment terms in writing. For a specialty chemical, lead times can be variable. Consider using a secure payment method that offers buyer protection, such as a letter of credit or an escrow service, especially for initial orders. Clarify the process for handling any quality discrepancies upon delivery.
Upon receiving the shipment, conduct an incoming quality check. This should include verifying the material's appearance against the description and, if critical to your process, sending a sample for independent assay testing to confirm the stated 99.0% purity. Establish a clear line of communication with the supplier's technical team to resolve any issues promptly and to facilitate future orders based on proven quality.
