    FAQ：

    Q: Are you a manufacturer?

    A: We are a manufacturer of both black silicon carbide and green silicon carbide materials. We began to produce silicon carbide powder since 1999.

     

    Q: What grade of silicon carbide do you have?

    A: We have several grades of silicon carbide powder including refractory grade, abrasive grade,etc.

     

    Q: How will you check silicon carbide quality before delivery?

    A: We will check the chemical composition and cleanness of the carborundum grain and powder. And inspect the gradation, bulk density of SiC grain and powder.

     

    Q: Do you support third-party quality inspection?

    A: Yes, we are open to getting a third-party quality test before delivery.

    Q: Is the silicon carbide you supply reclaimed material?

    A: No. We do the melting process by ourselves and don’t have reclaimed silicon carbide.

     

    Q: What is the HS code of silicon carbide abrasive powder?

    A: The HS code is 2849200000.

     

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

    A: Yes, it needs to provide an export license to Chinese customs. We could provide it and make customs clearance in China.

     

    Q: Are free samples available?

    A: Yes, we provide free samples within 1 kg. Customers only need to bear the logistic cost.
