What is the difference between DID and QDID?

Last Updated on：2024-12-11 09:57:22

QDID: Qualified Design ID, is the number assigned to a design scheme.

DID: Declaration ID, is the declaration number, similar to a certificate number.

For each technical scheme of a design company, when applying for BQB certification, the alliance will assign a number QDID to this technical scheme and obtain a certificate number DID. Each DID will indicate which technical scheme (QDID) this product uses. Downstream products can reference the test results of the technical scheme, which is the role of QDID. Our QDID is also based on the test results of the chip manufacturer's QDID, with additional testing of the differences to obtain a new QDID. Since the customer has not made any changes to the design, they can directly refer to Tuya's QDID to apply for the product's DID certificate.
