Does a parent company certificate cover my factory?
Do not accept group ownership as proof of certificate coverage. Match the named holder, manufacturing address and activities against the complete certificate and annexes, then obtain issuer confirmation that your production site is included. Cambridge China Bridge can help check the factory identity with its own staff in China.
Start with the holder and the production site
A certificate in a parent company's name is a reason to investigate coverage, rather than automatically accept or reject it. Ask the supplier to identify the certificate holder, the company taking your order and the company operating the actual production site. Record their full names and addresses separately.
Ask what kind of evidence the document provides before assessing group coverage. Our certification guide explains the differences between management system certification, product conformity markings and test reports. This guide focuses on connecting the named holder to the factory making your order.
Read the complete certificate and annexes
Request the complete current certificate, every referenced scope annex and the manufacturing-site schedule. Compare the certificate reference, holder, issue details and revision across the documents. A cropped front page or an annex without a clear connection to the main certificate leaves the evidence incomplete.
Find the exact production address and read the activities assigned to that site. Look for your product family and the relevant manufacturing processes. An entry for sales, procurement or warehousing does not establish manufacturing coverage. Where wording is broad, ask the issuer whether the activity you intend to buy falls within it.
Resolve name and address differences
Ask for a written explanation of differences between the certificate, quotation and factory details. Keep the original Chinese names alongside translations, and distinguish a trading name from the company name. A group chart can explain relationships, but use it as supporting information rather than proof that a site is covered.
Check the proposed production location through factory records and an on-site visit where appropriate. Ask which processes happen there and which are subcontracted elsewhere. Our factory audit checklist covers the wider visit; here, the aim is to connect the certificate's site entry to the premises and activities actually used.
Get confirmation directly from the issuer
Find the issuer's contact details independently. Send the complete document pack, holder name, certificate reference, production address and proposed activities. Ask: Is this certificate current? Is this exact site included under this holder? Does its scope cover these manufacturing activities? Which annex or site entry establishes that coverage? Request a written reply identifying the documents checked.
Government guidance describes accreditation as assurance of the competence of bodies carrying out certification and other assessment activities. Keep that issuer check separate from your site-coverage enquiry. A genuine certificate or an accreditation logo alone does not answer whether your factory is included. Record an unanswered or ambiguous enquiry as unresolved.

Record a bounded purchasing decision
Treat coverage as confirmed only when the documents and issuer's reply agree on the holder, site and relevant activities. If they conflict, request corrected documents or clarification before relying on the certificate for supplier approval. If the site is excluded, ask for evidence covering that site or assess another supplier against your purchasing criteria.
Save the certificate, annexes, issuer correspondence and production-site details in the order file. Ask the supplier to notify you before changing the site or subcontracting arrangements, then review coverage again. Site coverage still leaves product-specific evidence to assess; use our test report verification guide for that separate check.
Frequently asked questions
Can I accept a certificate in the parent company's name?
Potentially, after checking the complete certificate and annexes and obtaining issuer confirmation of the actual site's coverage and activities. Shared ownership alone is insufficient evidence.
What if my factory is missing from the certificate?
Request all referenced site schedules and scope annexes. If the address remains absent, ask the issuer how coverage is documented. Keep it unresolved until the issuer provides a clear answer.
Does a genuine group certificate cover every subsidiary?
Do not assume so. Check the named holder, listed sites and activities, then ask the issuer about the specific subsidiary and production address making your order.
What should I ask the certificate issuer?
Ask whether the certificate is current, whether the exact production site is included, whether its manufacturing activities are covered and which annex or site entry supports the answer.
