Perhaps 'Approved third parties' would be better.

The inspections can be conducted by the Health Authority or by a Third Authorized Party.

COFEPRIS also accepts certificates issued by the following countries, meaning that inspection by Mexico is not required if certification by these high-sanitary surveilliance countries is submitted: USA, Brazil, Canada, countries of the EU, Japan and Australia.

Authorized Third Parties
Starting in 2012, the possibility of having submission dossiers pre-revised by private parties especially authorized by COFEPRIS in order to reduce revision times later was introduced.

How does it work?

The pharmaceutical company that intends to register a drug product, contacts an authorized third party, which is an independent professional or company that has gone through an exam to be especially authorized by the health authority to pre-revise dossiers. The relations (conditions of confidentiality, timings, prices, communication arrangements) are specified in a contract between the Authorized Third Parties (ATPs) and the client, and COFEPRIS doesn’t have any inference into that.
