Sourcing Optical Brightening Agent Ob-1 from Shandong Raytop Chemical Co., Ltd. - China Import Guide
Before committing to a purchase, verify that Shandong Raytop Chemical Co., Ltd. holds a valid business licence and matches the harbour trust tier shown in the marketplace. Request a recent Certificate of Analysis that details purity, particle size and any residual solvents. Because the listing does not provide certification details, ask the supplier to supply safety data sheets and any applicable regulatory compliance documents.
Discuss logistics early by confirming the preferred Incoterm, whether FOB Jinan port or CIF Shanghai, and the expected lead time for bulk drums or bags. Clarify the minimum shipment size, as the supplier has not disclosed a MOQ, and arrange freight forwarding arrangements that accommodate the 25 kg or 500 kg packaging. Agree on payment terms such as T/T or L/C and ensure they are reflected in the pro‑forma invoice.
Plan a quality assurance step by organising a third‑party inspection of the powder before loading, focusing on purity, moisture content and particle‑size distribution. Request that the supplier provide a batch‑wise test report and retain samples for in‑house verification of fluorescence performance. Documentation should include a Material Safety Data Sheet, a Certificate of Analysis and any export‑related certificates required by the importing country.
