For brands that need small-dose filling support for skincare, scalp care, spot care, cleansing oil, nail, lash, brow or oral-care liquid samples.
Review formula source, benefit story, label route, secondary pack and pilot quantity before committing to a larger commercial run.
Turn a broad idea into a supplier-ready brief with product type, formula status, fill volume, format route, timing and market use case.
Use a controlled pilot to test filling behavior, pack-out, handling, channel response and reorder logic before scaling.
Filling route
A cosmetic filling RFQ should explain what the liquid is, how it will be used, which channel it serves and whether your team needs only filling or full OEM/ODM support.

For approved formulas that need compatibility review, small-dose filling planning and sample pack-out support.
For teams that need factory formula direction, sample rounds, benefit positioning and packaging fit before quotation.
For proprietary cosmetic formulas that should be reviewed confidentially before factory-side preparation.
For teams moving from sachets, mini bottles, vials, droppers, glass ampoules or bottle plus applicator into a cleaner sample route.

Format fit
BFS ampoules for serum, essence, booster, mask essence and small-dose cosmetic liquids.
Plastic ampoules for teams comparing glass ampoules, mini bottles, vials and premium sample formats.
Mixed trial kits for skincare, scalp, spot care, nail prep, lash and brow or channel-specific sample programs.
RFQ checklist
A useful RFQ connects category, formula status, sample format, pilot quantity, documents and the next commercial decision before price negotiation starts.
Product category: skincare, serum, essence, booster, cleansing oil, scalp liquid, spot-care liquid, nail prep, lash and brow, oral care or other cosmetic liquid.
Formula status: ready formula, NDA transfer, factory formula direction, formula modification needed or no formula yet.
Contract filling scope: bulk preparation, small-dose filling, pilot run, sample kit assembly, labeling, pouch, carton or full turnkey review.
Packaging route: BFS ampoule, plastic ampoule, sachet, mini bottle, vial or mixed sample kit.
Commercial details: target fill volume, unit count, pilot quantity, artwork timing, launch market, channel and document needs.
Buying trigger: distributor approval, GWP campaign, professional handoff, retail buyer review, influencer seeding, travel kit or private-label launch.
Quality, delivery, after-sales
Steridose Labs helps your team connect formula readiness, category fit, small-dose format, quality documents, lead-time variables and after-pilot scale-up planning.
Review the evidence behind the proposal
Identity and scope
Confirm the document holder, production site and applicable product scope.
Relevant records
Review available quality-system references and project-specific requirements.
Pilot evidence
Agree on compatibility, quality checks and acceptance records before scale-up.
Document access depends on project qualification and confidentiality.
We first check the liquid type, use case and target channel so the filling route is not chosen only by lowest unit cost.
Qualified B2B sourcing teams can review project-relevant factory proof, cleanroom references and quality documents before launch planning.
After the pilot, review filling behavior, pack-out feedback, user handling, channel response and the next production quantity.
FAQ
Cosmetic contract filling samples are small-dose or sample-format cosmetic liquid units filled by a factory for trials, GWP, distributor demos, professional channels, private-label presentations or pilot runs.
Agree whether you are reviewing the formula, container compatibility, opening and dispensing, or the complete labelled pack. Record the version and the questions being assessed. A development sample does not by itself confirm production readiness or the final manufacturing schedule.
Qualified projects can review ready formulas, NDA formula transfer, factory formula directions, small-dose formats, secondary packaging and pilot-to-scale planning together.
Standard BFS commercial pilot production usually starts from 10,000+ units. A 5,000-unit BFS run is not currently confirmed; written factory approval is required before it can be quoted.
Next step
We will review whether your cosmetic sample filling project belongs in BFS ampoules, sachets, mini bottles or a mixed sample kit, then outline the RFQ details needed for a practical pilot.
