WHERE PRODUCTION HAPPENS

Suzhou Xilin: Manufacturing and R&D

Production for WUMO projects runs at Suzhou Xilin Technology Co., Ltd., WUMO’s own production site. Suzhou Xilin runs an industrialisation base in Suzhou and an R&D centre in Beijing, with over 3,000 m² of production space, approximately 600 m² of Class 10,000 cleanroom production areas, cosmetic production equipment, and in-house filling and packaging lines. The cleanroom areas were tested in October 2025 by a CNAS/CMA-accredited laboratory — 25 rooms, including the filling room and sterile room, covering airborne particles, air changes, pressure differentials, settle plates and active air sampling — and all items passed. The ISO 22716 certificate shown below is held by Suzhou Xilin Technology Co., Ltd. and covers cosmetic finished goods; it is not a pharmaceutical GMP certificate and does not cover peptide synthesis, lyophilization or vial filling.

Buyers evaluating a WUMO project can see the facility, read the certificate, and request the batch documentation that comes with it — the same evidence an on-site audit would start from.

FACILITY CAPABILITY

Facility and Production Capabilities

Over 3,000 m² of production space

A Suzhou industrialisation base and a Beijing R&D centre, covering formulation development, production, filling, packaging, and quality control on one site.

Approx. 600 m² of third-party tested Class 10,000 cleanroom areas

In October 2025 a CNAS/CMA-accredited laboratory tested 600 m² across 25 rooms — including the dedicated filling room and sterile room — for airborne particles, air changes, pressure differentials, temperature and humidity, settle plates and active air sampling. All items passed. The test report is available on request.

Emulsification and production equipment

Cosmetic production equipment covering the liquid and cream/emulsion categories named in the ISO 22716 certificate scope, plus semi-finished bulk.

Filling and packaging lines

In-house filling and packaging, so the packaging format is decided together with the formulation and documented batch by batch.

Sample, pilot, and commercial batches

A project can start as a sample batch and scale to pilot and commercial volume at the same site. Capacity for a given project depends on the formulation and the schedule.

R&D and technical review

Formulation development and peptide technical review sit alongside production, so specification questions are settled before a batch is scheduled.

BUYER FAQ

Manufacturing and Documentation Questions

What manufacturing capabilities are available for WUMO projects?

Production runs at Suzhou Xilin Technology Co., Ltd., WUMO’s own production site: over 3,000 m² of production space including approximately 600 m² of Class 10,000 cleanroom areas — third-party tested in October 2025 by a CNAS/CMA-accredited laboratory across 25 rooms, all items passed — plus emulsification and production equipment, in-house filling and packaging, and QC laboratory work. Cosmetic production is covered by an ISO 22716:2007 management system; that certificate covers cosmetic finished goods and does not extend to peptide synthesis, lyophilization or vial filling.

What quality documents can buyers request?

The COA for the batch you would receive, SDS/MSDS, specification sheet, HPLC and MS data for the batches on file, batch and release records, and the ISO 22716 certificate. Tell us which documents your QA team requires and we will confirm what is available before you order.

Can buyers review the ISO 22716 certificate?

Yes. The certificate is shown in full on this page and can be downloaded as a PDF. It is held by Suzhou Xilin Technology Co., Ltd., covers ISO 22716:2007, and is valid from 20 October 2025 to 19 October 2028.

What formulations and packaging formats can be produced?

The certificate scope covers general liquid and cream/emulsion cosmetics, including permitted children’s skincare and eye-care categories. Filling and packaging are handled in-house, so the packaging format is agreed together with the formulation. Send your target format and volume and we will confirm feasibility.

Can you support sample, pilot, and commercial production planning?

Yes. A project can start with a sample batch, move to a pilot run for market testing, and scale to commercial production at the same site. We plan the schedule, documentation, and packaging for each stage with you.

What information is needed for a manufacturing quotation?

The product concept or formula, target format and fill size, packaging direction, order volume and reorder expectation, the market you are selling into, required documentation, and your timeline. With that we can quote or tell you what still needs to be defined.
