Contract manufacturing for cosmetics means a brand hires a manufacturer to make its product, from formula and raw materials to filling, packaging and batch testing, and then sells it under its own name. The brand owns the brand and, on a custom formula, the formula. The manufacturer runs production under cosmetic GMP and documents every batch.
Most founders who write to us have the same problem: a product idea, sometimes a finished formula, and a launch date, but no factory, filling line or quality lab. A contract manufacturer closes that gap. What founders rarely get is a clear picture of who does what and what a quote should contain. This guide covers both.
What is contract manufacturing in cosmetics?
Contract manufacturing is when one company produces goods that another sells under its own brand; the producer is the contract manufacturer. In cosmetics, a skincare contract manufacturer typically compounds the batch, fills and assembles the units, applies packaging and labels, runs quality checks and ships the finished goods.
The brand launches without owning a plant and keeps the name, the positioning and the customer. The manufacturer brings the equipment, staff and quality system. As a cosmetic contract manufacturer, we take a project "whether you have a finished formula or just an idea" through to finished goods.
The models: full-service, private label, custom formula, and toll or fill-only
The common models are:
Full-service (turnkey). The manufacturer handles formula, raw materials, packaging components, filling, testing and shipping.
Private label. The brand picks one of the manufacturer's existing formulas and launches it in its own packaging. It is a fast path to launch and suits first launches and seasonal drops.
Custom formula (OEM/ODM). The manufacturer's R&D team builds a formula to the brand's brief, or takes over a formula the brand's own chemist already wrote.
Toll or fill-only. The client supplies the materials and the manufacturer processes them for a fee.
Hong Shin works in three of these ways: Private Label, OEM/ODM, and Wholesale (bulk finished or semi-finished goods for distributors and multi-store retailers). We source the raw materials ourselves, which is what puts our projects in the contract model rather than the toll model. For the full definitions, see our guide to OEM vs ODM cosmetics.
Contract manufacturing vs private label: which one do you need?
They are not opposites. Contract manufacturing is the wider arrangement, and private label is one way to use it, alongside custom OEM/ODM and toll production.
The choice comes down to the formula. If an existing one fits and speed matters, private label is usually enough. If the formula is your differentiation or you need exclusive IP, choose custom development. Our post on white label vs private label skincare covers the branding side of that decision.
How a cosmetics contract manufacturing project works, step by step
So what occurs in contract manufacturing once you sign up? At Hong Shin, every project runs through five steps.
Brief and NDA. We sign a mutual NDA. You share your SKUs, volumes, packaging, timeline and target landed cost.
Quote and spec. We send a costed quote and specification, with MOQs, lead times and indicative pricing, within five business days.
Sampling. Lab samples, stability testing and packaging mockups. You sign off before tooling.
Pilot run. The first commercial batch, with quality control and a certificate of analysis (COA) per batch.
Ship and scale. Finished goods ship FOB Taiwan or DDP to your destination, and you reorder when ready.
On our Taiwan lines, retail bottles, tubes and jars take 10 to 12 weeks from formula sign-off. Products that route to our Korea lines are quoted separately.
Who owns and does what: the brand vs the contract manufacturer
This is where projects go wrong. Here is how responsibility usually splits, stage by stage, and which document changes hands.
Formula
Brand: approves the formula, or supplies one for transfer from its own formulator.
Manufacturer: develops or adapts the formula in house (texture, scent, clean-ingredient and botanical work).
Document: the approved formula and specification.
Raw materials and packaging components
Brand: approves the packaging choice and supplies the artwork.
Manufacturer: sources and qualifies the materials and components.
Document: the specification each material is checked against.
Stability and compatibility testing
Brand: reviews the results and signs off on samples.
Manufacturer: runs stability, compatibility and preservative efficacy (PET) testing.
Document: test results and the sample sign-off.
Production and QC
Brand: approves the pilot run.
Manufacturer: produces under ISO 22716, runs batch QC and issues a COA per batch.
Document: the COA and the batch records.
Adverse event records
Brand: according to FDA, under MoCRA the responsible person reports serious adverse events to FDA and keeps records of them. To do that, it needs the manufacturer's batch records, so ask up front which ones you can request. Our ISO 22716 guide explains the clauses that matter to a brand.
Manufacturer: keeps the batch records and assesses any change to materials, suppliers or processes before it happens (change control).
US facility registration and product listing (MoCRA)
According to FDA, the work is split like this:
Facility registration: owners or operators of facilities that manufacture or process cosmetics for US distribution must register each facility with FDA, update changes within 60 days and renew every two years. A contract manufacturer needs one registration per facility, even when it makes products for several brands.
Product listing: the responsible person, which FDA defines as the manufacturer, packer or distributor whose name appears on the label (usually the brand), must list each marketed product with FDA, including its ingredients, and update the listing annually.
Order: each listing must include the registration number of every facility where the product is made, so the facility registers first.
What it does not mean: FDA says it does not issue certificates of registration or listing, and a registration or listing number does not mean FDA approval. FDA notes that MoCRA exempts certain small businesses from registration and listing, though not for some product types.
Hong Shin holds US FDA facility registration. For the wider picture, read our MoCRA explainer.
Label, claims and other markets
Brand: owns its label content and claims.
Manufacturer: supports regulatory filings. We support Health Canada NPN and cosmetic notification, US FDA OTC and 25(b), EU CPNP and UKCA work.
Who owns the formula, the IP and the packaging tooling?
Custom OEM/ODM formulas. On a custom development project with Hong Shin, you own the IP. That covers formulas built from the ground up by our R&D teams in Taiwan and South Korea and formulas transferred from your own chemist.
Private label formulas. These are the manufacturer's existing formulations, and at Hong Shin there are more than 130 across twelve categories. You sell the product under your brand, but the stock formula stays the manufacturer's.
Packaging tooling. If your packaging needs a custom mold, get in writing who owns that tooling and that the design stays yours before any tooling is cut. Changes after tooling are the most expensive kind, and a quote with no line for one-off setup work usually hides those costs somewhere else.
What is on a cosmetics contract manufacturing quote
From the factory side, expect these lines:
Formula and sampling. At Hong Shin, sampling is tiered: USD 120 for private label (an existing formula as is), USD 300 to build on an existing formula adjusted to your brief, and USD 500 for full custom development.
Raw materials. In the contract model, these are sourced by the manufacturer and included in the quote.
Packaging components. Bottles, jars, tubes, pumps and caps, plus any decoration.
Filling and assembly. Including sachet sampling (1 to 10 mL) and kit assembly if you need them.
Quality control and the COA. Batch testing and a certificate of analysis per batch.
Shipping terms. FOB Taiwan, or DDP to your destination.
Minimum order. A first order starts from 1,500 units per SKU made in Taiwan and 3,000 units per SKU made in Korea. SPF serums and cream serums are made on our Korea lines, so they start at 3,000.
Be careful with a quote that looks cheap because it leaves out testing or documentation. For more on order sizes, read our private label skincare MOQ explainer.
The contract manufacturing agreement: what to get in writing
This is general guidance, not legal advice, and you should have a lawyer review the agreement before you sign. At a minimum, get these in writing:
The NDA and the product specification.
Who owns the formula and any custom tooling.
Quality and testing responsibilities, and whether a COA comes with every batch.
Change control for materials, suppliers and processes.
Lead time milestones and payment terms.
Benefits and risks of using a cosmetic contract manufacturer
Benefits for a brand
No factory to build, staff or certify.
Access to GMP production, R&D, testing and regulatory support.
Risks, and the control for each
Quality drift: choose a manufacturer certified to ISO 22716 and require a COA per batch.
Schedule slips: tie lead time to a milestone in the agreement, such as formula sign-off.
IP exposure: sign an NDA first and set formula ownership in writing.
Documentation gaps: agree which batch records you can request before production starts.
Compliance and silent changes: confirm who files in each market, and insist on change control.

FAQ
What does a cosmetic contract manufacturer do?
It makes products another company sells under its own brand: formula work, material sourcing, compounding, filling, packaging, QC with batch documentation, and shipping.
What is the difference between toll manufacturing and contract manufacturing?
The difference is who supplies the raw materials. In contract manufacturing, the manufacturer sources the materials and includes them in its quote. In toll manufacturing, the client supplies the materials and pays a processing fee.
Do I own my formula if I use a contract manufacturer?
It depends on the model. On a custom OEM/ODM project with Hong Shin, you own the IP. With private label, the stock formula remains the manufacturer's.
What is the minimum order for cosmetic contract manufacturing?
At Hong Shin, a first order starts from 1,500 units per SKU made in Taiwan and 3,000 per SKU made in Korea, where SPF serums and cream serums are made. Our MOQ explainer covers how MOQs work.
Who registers with the FDA under MoCRA, the brand or the contract manufacturer?
According to FDA, the facility's owner or operator registers the facility, and the responsible person (the company named on the label, usually the brand) lists each product. FDA notes that registration and listing do not mean FDA approval.
