FAQs
What is colored sand and what are its main uses?
Colored sand is a sand product made by dyeing or processing natural/artificial sand, featuring stable color, good weather resistance and non-toxicity. It is widely used in architectural decoration (e.g., stone-like coatings, epoxy floors), craft making, landscape design, and children educational toys.
Which regions are the main exporters of colored sand?
The main exporting regions include China (abundant sand resources and large-scale processing capacity), the United States, India, and Spain. These areas dominate global supply due to mature coloring technologies and consistent product quality.
What quality standards should I pay attention to when importing colored sand?
Key parameters include: color fastness (no fading after 500+ hours of UV exposure), particle size distribution (common grades: D50=40-120μm), water resistance (no color bleeding after 24-hour immersion), and harmful substance content (compliant with EN71-3 for toy-grade products). Certifications like ISO 9001 may also be required.
How is colored sand packaged for international transportation?
It is usually packed in 25kg woven bags with inner plastic liners; for large orders, 500kg/1000kg bulk bags or bulk shipping are available. It is critical to mark product specifications, batch numbers, and safety labels (e.g., "non-hazardous goods") on the packages
What are the common trade terms in colored sand trade?
Common terms include FOB (Free On Board), CIF (Cost, Insurance and Freight), and EXW (Ex Works). The selection depends on negotiations between buyers and sellers regarding transportation responsibilities and costs.
What documents are required for importing colored sand?
Required documents include commercial invoice, packing list, bill of lading (B/L), certificate of origin, and quality inspection report. For toy-grade colored sand, additional certificates (e.g., EU CE certification) may be needed in some regions.
What payment terms do colored sand suppliers commonly accept?
Suppliers usually accept letters of credit (LC), telegraphic transfer (TT), or secure payment platforms (e.g., Alibaba Trade Assurance). The standard practice is to prepay 30% as a deposit, and the balance is paid before shipment.
Can colored sand be customized for specific industrial uses?
Yes, suppliers offer tailored grades based on client needs, such as:
High-weather-resistance colored sand (for outdoor architectural coatings).
Fine-grained colored sand (for delicate craft making).
Non-toxic colored sand (for childrens sand art toys).
