Certificate Register
Numbers, issuing bodies and the register each one is checked in, so a buyer can confirm scope and current status independently rather than take our word for it.

Why the certificates carry a different company name
These certificates were issued to Shandong Longgang Silicon Technology Co., Ltd., the company’s former registered name. The name changed to Shandong Zhongzhi Chemical Technology Co., Ltd. on 2026-04-10. It is the same legal entity: the unified social credit code is unchanged, and appears on both the certificates and the current business licence. A company’s credit code does not change on a rename, which is what makes the two names checkably the same company.
