What is kaolin, and what are its primary applications
Kaolin is a white, clay-like mineral composed mainly of kaolinite. It is widely used in ceramics, paper, paints, coatings, plastics, rubber, and environmental protection (e.g., wastewater treatment) due to its excellent whiteness, chemical stability, and adsorption properties.
What are the main export regions for kaolin
Major exporting countries include the United States, Brazil, China, India, and Australia. These regions dominate global production due to abundant reserves and advanced processing technologies.
What quality standards should I look for when importing kaolin
Key parameters include whiteness (brightness ≥85%), particle size distribution (D50 <2μm for premium grades), moisture content (<1%), and chemical purity (low iron/titanium content). Certifications like ISO 9001 or industry-specific standards (e.g., ASTM for ceramics) may be required.
How is kaolin packaged for international shipping?
Kaolin is typically packaged in 25kg or 50kg multi-layer paper bags, or in bulk (ton bags/flexitanks) for large orders. Proper labeling with product specs, batch numbers, and safety marks (e.g., "Non-Hazardous") is essential.
What are the common Incoterms used in kaolin trade
Frequently used terms include FOB (Free On Board), CIF (Cost, Insurance, Freight), and EXW (Ex Works). The choice depends on negotiation between buyer and seller regarding shipping responsibilities and costs.
What documents are required for customs clearance when importing kaolin?
Required documents include a commercial invoice, packing list, bill of lading (B/L), certificate of origin, and quality inspection report. Some countries may require additional permits (e.g., environmental compliance certificates)
How long does shipping take for kaolin from major export hubs?
o From the China (Tianjin) to Europe/Asia: 30 to 45 days (sea freight). o From China to Brazil: 25 to 40 days. o From China to Southeast Asia: 7 to15 days. Air freight is faster but costlier, typically used for urgent orders.
