How to verify a cosmetic packaging supplier before you order
By the Good Partner production and sourcing team. 11 min read.
Why verification matters in this industry
Cosmetic packaging sourcing has an unusually wide gap between a manufacturer and a trading company. A trading company can present a factory, quote competently and deliver. Nothing in the transaction tells you which one you have. The checks below do.
Step 1 — check the legal entity, not the website
Get the registered company name and the registration number. In China that number is the Unified Social Credit Code, and it is a public record: look it up on the National Enterprise Credit Information Publicity System, or in any corporate-registration database. You should be able to see the legal representative, registered capital, registered address and founding date. A supplier whose website facts contradict their registry record is telling you something. Note that a mismatch is not automatically fraud — outdated marketing material is common — but it should be explained.
Step 2 — ask for certificates with a number and a scope
Any competent supplier is registered in some government scheme. Beyond that, ask for the certificate number and the scope. An ISO certificate has a number, a scope and an expiry. A supplier who cannot produce a number has a certificate in name only. Compare that against suppliers who list certifications without numbers — it is common and it tells you what you are dealing with.
Step 3 — establish whether tooling is theirs or bought in
This one question separates a manufacturer from an assembler. Ask who designs and maintains the mould. In-house tooling means repeat orders land consistently and modifications can be made. Outsourced tooling means consistency depends on a supplier you have never visited and cannot control.
Step 4 — ask where the moulding happens
Follow it with a question about where moulding actually happens. A manufacturer will answer plainly and tell you where the equipment is. A trading company will answer vaguely.
Step 5 — make approval samples the gate, not email
Insist that first-article approval happens on physical parts before the production run. Renders and photographs are not specifications. If a supplier resists physical approval, you are buying on trust rather than on evidence.
Step 6 — settle tooling ownership in writing
Confirm in writing who owns customer-specific tooling and whether it can be used for anyone else. This is a short clause and it matters more later than it does at the start.
Step 7 — audit before the second order, not the tenth
Once you have a working relationship, a site visit becomes possible and much more useful. Do it before volume grows, while the relationship is still easy to be direct with.
The one-page version
Registry data consistent with the website. Certificate numbers supplied on request. Tooling in-house. Moulding location stated plainly. Physical approval before production. Tooling ownership in writing. If a supplier fails any of these, that is not automatically a reason to reject them — but it is a reason to get an answer before you commit.
