Is a production license the same as a design license?

Production and design are separated in the domestic market; two different certifications are required. ASME is a certification.

You can take a look at the Regulations on Special Equipment; the production of special equipment includes design, manufacturing, installation, modification, and maintenance, and in China these licenses are valid for four years.
