Audited Supplier The silicon carbide segment sand processed by Baotong has good particle size and fluidity. Content from 92% to 98%.
Q: What is the difference between green silicon carbide and black silicon carbide?
A: First of all, the SiC purity of green silicon carbide is higher (99%), and the purity of black silicon carbide SiC is at least 98%. Second, green silicon carbide is harder than black silicon carbide.
Q: Is your green silicon carbide powder an air sieve or a water sieve?
A: Our green silicon carbide powder is made by water sieving process (suspension treatment). The granules thus have a high consistency.
Q: What are HS codes and CAS NOs? Silicon carbide?
A: The HS code is 2849200000. CAS NO. is 409-21-2.
Q: Are there any restrictions on exporting SiC materials from China?
A: Yes, it must obtain an export license to export. We will provide it to customs.
Q: How many kilograms of free samples can we get?
A: We provide free samples less than 1kg. Customers have to bear the courier fee and DGM certificate fee.
Q: How do you inspect the products before delivery?
A: We will check items such as chemistry, density, particle size distribution and packaging before shipment. After delivery, we store each batch of samples for 3 months.
Q: Do you require MOQ?
A: The MOQ is 1 bag, always 25kg. Shipping cost will be higher than 1MT.
