We primarily offer custom services for inorganic chemical salts (such as high-quality barium carbonate, precipitated barium sulfate, and strontium carbonate) and mineral products (such as natural asphalt and chromite). We can customize chemical purity, particle size distribution (micronization/ultrafine grinding), moisture content, and specific physical parameters based on your application.
MOQ varies depending on the product and customization specifications (such as specific technical metrics or private labeling). Generally, the baseline for standard chemical products is one container load (approx. 20–25 metric tons). For new custom projects, we offer flexible trial order policies—please consult our sales team for details.
