Key Processes and Core Requirements for chemical supply

1. Production Link: Compliance as the Premise

• Qualification Requirements: Manufacturing enterprises must hold relevant certificates such as the "Hazardous Chemical Production License" (if hazardous chemicals are involved) and ISO 9001 quality management system certification.
• Quality Control: Inspections must be conducted in accordance with standards, including Incoming Quality Control (IQC) for raw materials, In-Process Quality Control (IPQC), and Final Quality Control (FQC) for finished products. A Certificate of Analysis (COA) must be issued and archived.
• Environmental Protection Requirements: Industrial wastewater and waste gas must be discharged up to standard, complying with national "three wastes" (wastewater, waste gas, solid waste) treatment standards (e.g., China’s GB 18484-2020).

2. Distribution Link: Demand Matching as the Core

• Hierarchical Distribution: First-tier distributors cooperate with large enterprises to provide "bulk centralized procurement"; second-tier distributors focus on small and medium-sized customers, offering services such as "small-batch splitting" and "multi-category integration".
• Compliance Support: A Safety Data Sheet (SDS) must be provided to downstream parties, specifying the chemical’s hazardous properties, first-aid measures, and leakage handling plans.
• Import and Export Services: For cross-border chemical supply, a "Hazardous Chemical Import/Export License" must be obtained, and compliance with the target country’s regulations (e.g., EU REACH, US TSCA) is required.

3. Warehousing and Logistics: Safety as the Bottom Line

• Warehousing Management:
  • Ordinary chemicals: Only well-ventilated and dry warehouses are required.
  • Hazardous chemicals: Must be stored in classified areas (e.g., flammable substances in separate explosion-proof warehouses, corrosive substances on anti-corrosion floors, highly toxic substances in cabinets with double locks managed by two persons), with fire-fighting equipment and emergency shower facilities installed.
  • Special chemicals: Need temperature-controlled storage (e.g., 2-8℃ for biological reagents) and protection from light.
• Logistics and Transportation:
  • Hazardous chemicals must be transported by specialized vehicles that meet the standards of the UN Recommendations on the Transport of Dangerous Goods (TDG), and escorted throughout the journey by personnel holding a "Hazardous Goods Escort Certificate".
  • Cold-chain chemicals (e.g., some biological reagents) must be transported by refrigerated trucks with temperature monitoring to ensure stable temperatures during transportation.
