According to the joint announcement released by the Ministry of Commerce and the General Administration of Customs on October 9, 2025, China has decided to implement export controls on some superhard materials and related items
I came across news about the regulation of superhard materials early this morning, and I feel quite uneasy. After all, once regulated, it may affect existing businesses.
Now let me share the relevant information I found online.

The table below summarizes the specific items and their key parameters subject to export control this time, with an effective date of November 8, 2025

* After carefully reading the regulatory items, the ones that have the greatest impact on our company are the 680421 diamond grinding wheel and CBN grinding wheel. However, in terms of entries, currently the most common is still ultrafine powder. Our company currently produces products in the field of people's livelihood, all of which are coarse-grained superhard materials. It should not be affected by this
