FAQ:

Q: What is the difference between green silicon carbide and black silicon carbide?

A: First of all, Green silicon carbide has higher purity of SiC(99%), black silicon carbide SiC purity is min 98%. Secondly, green silicon carbide is harder than black silicon carbide.

Q: Is the green silicon carbide powder from you by air flow sieving or water sieving?

A: Our green silicon carbide powder is made by water sieving process. So the particles are of high consistency.

Q: What are the HS code and CAS NO. of silicon carbide?

A: HS code is 2849200000. CAS NO. is 409-21-2.

Q: Is there any restriction to export silicon carbide material from China?

A: Yes, it has to get an export license to export. We will provide it to custom.

Q: How many kgs of free samples can we get?

A: We provide free samples less than 1 kgs. Clients have to bear the express cost and DGM certificate cost.

Q: How do you inspection products before delivery?

A: We will check items of chemical, density, particle size distribution and packing before delivery. After delivery, we keep samples of each batch for 3 months.

Q: Do you demand MOQ?

A: MOQ is 1 bag, always goes 25kgs. The transportation cost will be higher than that of 1MT.
