Bodies that certify products, processes or services need accreditation to ISO/IEC 17065. A manufacturer does not: it is the client of such a body, not the body itself.
The scope provision names bodies certifying products, processes and services. Those are the organisations that need accreditation to ISO/IEC 17065, and the people who run their quality, accreditation and technical functions. A manufacturer or service provider that holds a product certificate is the client, not the certification body, and does not need 17065 accreditation for that certificate. A scheme owner writes the rules and may require its bodies to be accredited. An accreditation body assesses against the standard. A regulator may designate or recognise a body that meets it. The free check on this site is written for the certification body, and it says so when the answer describes another role.
We are a scheme owner. Does this apply to us?
The requirements are written for certification bodies. A scheme owner can use the record to write scheme rules, but the free check is not written for that role and says so.
We certify management systems. Is 17065 right?
If the object is a management system, ISO/IEC 17021 is the usual standard. Some bodies hold both.
Where this comes from
The clause record states each requirement in our own words and cites the clause. The revision page separates the public FDIS record from the edition in force. The official record is ISO standard 94443.
Not legal advice; does not certify. The FDIS requirement wording is not held and is not stated.
