In short

Hangzhou Di Tong Biological Technology Co., Ltd. is a cosmetics manufacturer in Xiaoshan, Hangzhou, China, trading for export as Meier Spa. The plant holds a GMPC-compliant production base with 100,000-class and 10,000-class cleanrooms, keeps more than 10,000 mature formulas on file, quotes samples in 3 to 7 days and bulk production in 8 to 15 days, and fills skincare, hair care, body care and colour cosmetics under clients' own trademarks.

Four ways a brand can work with the plant

Most projects start on one route and move to another as volume grows. The formula owner does not have to change when the route does.

OEM: your formula, our line

You bring the formulation, the reference sample or the target claim. We scale the batch, validate stability and microbiology, and fill it in your packaging.

You own
The formula and the brand
We own
Compounding, filling, QC, documents

ODM: our formula, your brand

Pick from the stock library, then change texture, active dose, scent or packaging. You get a product that is genuinely yours without paying for development from zero.

Packaging and artwork

Bottles, droppers, airless pumps, tubes, sachets and cartons are sourced, matched and scheduled against the fill date, with artwork checked against your market's labelling rules.

Scope
Sourcing, matching, artwork review

Runs parallel to sampling

Export documentation

Every batch ships with the paperwork your importer asks for: certificate of analysis, safety data sheet, stability and microbiological records, and a product information file.

Notes from the plant

Short, practical writing for brand owners: how to vet a factory, how MOQ is really set, and what a freeze-dried project involves.

From brief to container in five stages

Sampling and packaging sourcing run in parallel, because the pack is usually the longest lead time in the project.

Brief

Category, target market, claims, volume, packaging and price band. One call is usually enough to define the route.

1–2 days

Formula match

We shortlist stock formulas or build a match against your reference sample, then send samples with a specification sheet.

3–7 days

Validation

Stability, compatibility with your chosen pack, microbiological testing and artwork review against local rules.

2–4 weeks

Bulk production

Compounding, filling, labelling and in-process checks in the cleanroom, batch by batch.

8–15 days

QC and dispatch

Finished-goods testing, retention sampling, certificate of analysis and export documents, then booking.

3–5 days

What the paperwork covers

A batch is only export-ready when the documents travel with it. These are the data points a quality team or an importer will ask for, and the ones the plant holds for every batch.

Production and quality control at the Hangzhou site
Production standardGMPC-compliant cosmetics production base, with documented process control from raw material intake to finished goods.
Cleanroom class100,000-class primary filling rooms and 10,000-class secondary suites for open-product handling.
Microbiological controlRoutine testing of bulk and finished goods, with environmental monitoring in the filling rooms.
Stability programmeAccelerated and real-time stability on every new formula and every new pack combination.
Batch traceabilityBatch records link raw material lots to fill date, line and QA release, so a complaint can be traced back.
Export documentsCertificate of analysis, safety data sheet, product information file and market-specific declarations on request.
Microbiology testing of cosmetic samples: petri dishes, pipette and balance on a stainless steel bench

Formula development: texture first, then active dose, then pack compatibility.

Development is where the shelf life is decided

A formula that feels right in a beaker can fail in your bottle. Every new combination of formula and pack goes through compatibility and stability testing before it is quoted as production-ready, which is why we ask for the pack before the sample.

The stock library shortens this work: more than 10,000 formulations already carry an ingredient list, a process sheet and stability history, so an ODM brief often starts from a tested base rather than a blank page.

How the plant is organised

Questions brands ask before ordering

Short answers, written for a first-time brand owner rather than a procurement department.

What is the difference between OEM and ODM cosmetics manufacturing?

In OEM, the brand owns the formula and the factory manufactures it. In ODM, the factory owns a stock formula and licenses it to the brand, usually with adjustments to texture, actives or fragrance. Meier Spa runs both routes on the same filling lines, and most first-time brand owners start with ODM because sampling is faster and development cost is lower.

What is the minimum order quantity?

There is no single number, because the minimum is set by the packaging rather than the formula: a stock bottle may run from a few thousand units, while a custom mould may need considerably more. Send your target volume and pack preference and we will return the lowest workable combination.

How long do samples and bulk production take?

Stock-formula samples are typically dispatched in 3 to 7 days after the brief is agreed. Bulk production runs 8 to 15 days after artwork and pre-production sample are signed off, with stability testing scheduled alongside rather than in series.

Do you supply brands outside China?

Yes. The plant is built for export and the document set is prepared for the destination market. Tell us the selling country at briefing, because labelling, ingredient naming and notification requirements differ and they change what we put on the carton.

Can you handle packaging, cartons and artwork as well as the fill?

Yes. We source and match bottles, pumps, tubes and cartons, and we review artwork against the labelling rules of your market before plates are made. Many clients hand us a logo and a colour reference and take the full turnkey package from there.

What documentation comes with a batch?

A certificate of analysis for the finished batch, the safety data sheet, stability and microbiological records, and a product information file covering the formulation. Additional declarations, such as heavy-metal or prohibited-substance statements, are added when the destination market requires them.
