Contract Manufacturing for Supplements: How to Choose the Right Facility
The short answer
Compare factories by authorised scope, capability for the intended dosage form, Good Manufacturing Practice (GMP), supplier controls and testing. Define the minimum order quantity (MOQ), intellectual-property terms, deviation handling and who prepares SFDA evidence and a Certificate of Free Sale (CFS) where applicable.
Three actions to take
- Verify the facility, production line and scope, not only a general certificate.
- Ask for a quotation separating development, materials, tests, packing and freight.
- Confirm ownership of the formula, files and artwork tooling before payment.
1. Technical and regulatory fit
The manufacturer should be able to produce the intended form, dose and pack within its scope and explain how materials, suppliers and finished specifications are controlled.
- Request the available lines, dosage forms and pack sizes.
- Review supplier approval, change, deviation and recall processes.
2. The real order economics
Unit price is not total cost. Include development, samples, tests, tooling, packaging, storage, minimum quantities and possible rework.
- Compare MOQ, lead-time and cash-flow scenarios.
- Separate one-time fees from per-batch cost.
3. Contract and file ownership
State who approves the formula, label and specifications and who supplies analyses, certificates and responses. A private-label model does not remove the brand owner’s duty to verify.
- Attach a responsibility and deliverables matrix to the agreement.
- Define data, sample and tooling ownership and an exit process.
