12 criteria for choosing a contract cosmetics manufacturer

Why price alone is not a sufficient measure

Price differences between contract manufacturing quotes are usually small; when a large gap appears, there is a reason for it. A cheaper quote often means less testing, less documentation or a weaker quality system. That difference is not paid for at production — it is paid for after the product reaches the field.

The criteria below let you assess a manufacturer beyond the quotation.

1. ISO 22716 (cosmetic GMP) certification

This certificate shows the production system has been audited on site by an independent body. "We manufacture under GMP conditions" and "we hold ISO 22716 certification" are not the same statement. Ask to see the certificate, and check its number and validity date.

2. An in-house quality control laboratory

Analysis can be outsourced, but an on-site laboratory enables fast decisions during production. Being able to check pH and viscosity before filling stops a faulty batch from reaching the field.

3. Raw material traceability

When an issue appears in a finished product, the raw material batch used must be traceable. Ask the manufacturer: "Can you find the supplier batch number of the glycerine used in a batch you produced six months ago?" How quickly they answer tells you a great deal.

4. Retention sample discipline

A reference sample should be taken from every batch and kept for the shelf life of the product. When a consumer complaint arrives, being able to assess a sample from the same batch as the product in the field protects the brand owner.

5. Scope of regulatory support

Some manufacturers only manufacture; the responsible technical person, ministry notification and product tracking registration remain your responsibility. Running those through a separate consultant adds both cost and coordination load. Establish exactly where the scope ends before signing.

6. Formula confidentiality guarantees

It should be in writing that a formula developed for you, or supplied by you, will not be offered to another brand. A verbal assurance is not enough. Equally, clarify whether a formula you select from a library is exclusive.

7. Transparency on MOQ and lead times

A manufacturer that will not give a clear answer on minimum order quantity and lead time will not be clear later either. Ask to see how unit price changes across volume scenarios — it lets you make the scale decision properly.

8. Packaging sourcing capability

Packaging is the longest item in most projects. Experience working with packaging suppliers, whether compatibility testing is performed, and the capacity to propose alternatives all speed the process markedly.

9. Capacity and headroom

A facility that is adequate for today's volume may fall short when your product succeeds. Assess capacity against your target two years out, not today's. Line count, tank capacity and daily filling volume are the numbers to ask for.

10. Verifiable references

For competitive reasons not every manufacturer can share a client list, and that is normal. You can, however, ask for anonymised case accounts: which category, how many SKUs, in what timeframe. Concrete accounts inform more than general statements.

11. Openness to site visits

Do not work with a manufacturer reluctant to show you the plant. On a visit, look at clean-room layout, the order of the raw material store, record-keeping discipline and how well staff know their processes.

12. Contract clarity

Intellectual property, confidentiality, liability for defective production, delivery delay, minimum order commitments and price revision terms should all appear explicitly. These clauses are always harder to discuss afterwards.

A short checklist

• Have you seen current copies of the certificates?
• Have you visited the facility in person?
• Is the boundary of regulatory scope in writing?
• Is formula confidentiality in the contract?
• Have you received price scenarios at different volumes?
• Have you assessed the product from a physical sample?
