CPA Certification for Measuring Instruments

Since November 1, 2020, several measuring instruments require CPA certification (China Pattern Approval) to be imported into China. Manufacturing and sale of these products in China is also only possible with a valid CPA certificate.

China Pattern Approval Logo

The responsible certification authority is the Chinese market regulation authority SAMR (State Administration for Market Regulation).

There are two surveillance modes for CPA registration:

P (type approval) or P+V (type approval + mandatory verification)

Type Approval P must be conducted by the manufacturer of the product before importing into China. Mandatory Verification V must be performed annually by the user of the product in China.

CPA Registration Guidelines

The implementation of CPA certification (China Pattern Approval Certification) is prescribed by the following legal texts:

Rules for the Implementation of the Metrology Law of the People’s Republic of China
Measures of the People’s Republic of China for the Supervision and Administration of Imported Instruments of Measurement
Detailed Rules for the Implementation of the Measures of the People’s Republic of China for the Supervision and Administration of the Imported Measuring Instruments
