The direct answer
Price and lead time are easy to compare; the harder check is whether the factory can hand over the documents the destination market expects. These questions separate a repeatable supplier from a quote-only contact.
The product information file
Ask whether a product information file and safety assessment exist for the formula, and whether it reflects the exact ingredient version you are ordering. A file built for another product should not be reused without updating.
The responsible party and registration
For an EU-bound order, confirm the responsible person; for a US-bound order, confirm establishment registration posture; for other markets, ask which local filing applies. The brand should know who holds each role.
Stability, compatibility and input changes
Request packaging compatibility and stability records for the actual component and formula. Ask how the factory handles a pigment, fragrance, component or supplier change and whether a re-approval sample is required.
Frequently asked questions
Can a shared safety file cover multiple brands?
Only if it reflects the exact formula, packaging and destination; otherwise it must be rebuilt.
Who is the responsible person in the EU?
Ask the factory which role it can support and who acts as the EU responsible person.
What triggers a new dossier?
Formula, ingredient, fragrance, component or supplier changes can each require updated documentation.
