A manufacturing partner, not just a vendor
You own the brand and the market; we own the factory floor.
Contract manufacturing means we take responsibility for your product end to end: formula development, raw material sourcing, production, quality control, packaging, and export logistics. You own the brand and the market; we own the factory floor.
What our contract covers
- R&D — recipe development by a team producing ~20 new products a year, backed by 20 invention patents
- Sourcing — herbal and functional ingredients with incoming QC
- Production — teas, capsules, tablets, gummies, powders, patches, and jelly on 13 lines in a 5,235 m² facility
- Quality — ISO9001, ISO22000, HACCP, GMP standards; HALAL; FDA-registered; 2 QA/QC inspectors; 100,000-class clean workshops
- Packaging — bags, bottles, boxes, tins with your branding
- Export — documentation and shipping to 30+ countries; 99.5% on-time dispatch record
Who we work with
Brand owners launching or scaling supplement and tea lines; retailers building store brands; wholesalers needing consistent contract supply; manufacturers outsourcing overflow. Our main export markets are Africa, North America, and Southeast Asia, with growing business in Europe and the Middle East.

The company behind the factory
Guangzhou Wansongtang Biological Technology Co., Ltd. is a wholly-owned subsidiary of Wansongtang Health Group, a health-products group founded in 1996. The Guangzhou company was established in 2011 and operates from Guangzhou, Guangdong, China, where it runs a 5,235 m² facility equipped with 13 production lines and 30 sets of equipment. Production takes place in 100,000-class clean workshops staffed with 2 dedicated QA/QC inspectors. The company holds ISO9001, ISO22000, HACCP and GMP standards certifications, HALAL certification, FDA registration, export food enterprise filing, and recognition as a National High-Tech Enterprise. It produces under its own brands — Winstown (the main export brand), Wansongtang, and Daynee — and offers OEM, ODM, private label, and wholesale services. Together these facts describe a supplier that manufactures for its own labels as well as for clients, which is a useful signal when you evaluate any contract manufacturer.
Product categories we manufacture
Understanding what a factory actually runs on its lines is the first filter in supplier selection. Our production covers:
- Functional, flavor, and herbal teas — pyramid bags, flat bags, string-and-tag bags, and loose leaf
- Instant powders — for drinks and functional blends
- Gummies
- Tablet candy
- Capsules
- Softgels
- Patches
- Jelly
That range matters for buyers planning more than one SKU: a single contract partner that can produce tea, a supplement format, and a functional confection removes the coordination cost of managing multiple factories, multiple quality systems, and multiple shipping schedules.
How a contract manufacturing project runs
Every project follows roughly the same path, though the details depend on whether you bring a formula or ask us to develop one.
- Brief and scope — you share the product concept, target format, packaging direction, target market, and volumes. This determines whether the project is full contract, your-formula, or private label.
- Development — for full contract work, our R&D team develops the recipe. The team produces around 20 new products a year and the company holds 20 invention patents, so formulation is a core in-house function rather than an outsourced step.
- Quotation — MOQs and pricing are quoted per project. Bulk OEM is priced according to the specific project, because ingredient costs, packaging, and run sizes vary widely by format.
- Sourcing and incoming QC — herbal and functional ingredients are sourced and inspected on arrival before they enter production.
- Production — manufacturing runs on 13 lines in 100,000-class clean workshops.
- Quality control — 2 QA/QC inspectors oversee quality through the run, within the ISO9001, ISO22000, HACCP and GMP standards frameworks.
- Packaging — bags, bottles, boxes, and tins are packed with your branding.
- Export — we prepare documentation and ship. The company exports to 30+ countries and regions across North America, Europe, the Middle East, Africa, and Southeast Asia, and records 99.5% on-time dispatch.
The average development cycle runs about 15 days from concept to finished product. Production lead times are confirmed at quotation.
Buyer FAQs
What are the minimum order quantities? MOQs depend on format. Tea in retail pack starts from roughly 100–120 bags or boxes. Gummies and tablets start from roughly 100–150 boxes. Bulk OEM is quoted per project.
Can you manufacture from my existing formula? Yes. The "your formula" engagement model exists exactly for this: you provide the recipe, and we handle production and packing. If you need formulation help instead, choose full contract and our R&D team develops the product.
What certifications does the factory hold? ISO9001, ISO22000, HACCP, GMP standards, HALAL, FDA registration, export food enterprise filing, and National High-Tech Enterprise status. These are the certification names; documentation is shared during supplier qualification.
Which markets do you export to? 30+ countries and regions, spanning North America, Europe, the Middle East, Africa, and Southeast Asia. On Alibaba, the main markets are Africa at 50%, North America at 20%, and Southeast Asia at 10%.
How long does development take? About 15 days from concept to finished product on average, for projects where we handle development. Timelines for your-formula projects are typically shorter because the recipe already exists.
What are your trade credentials? A 4.6/5 rating across 53 Alibaba reviews, response within 4 hours, 99.5% on-time dispatch, and US$140,000+ in online orders.
What to look for in a contract manufacturer
Whether you work with us or evaluate alternatives, the same checklist applies:
- Certifications, not claims. Ask for the specific certification names a factory holds — ISO9001, ISO22000, HACCP, GMP standards, HALAL, FDA registration, export food enterprise filing — and confirm they cover the product category you are buying.
- Format coverage. A factory that runs tea lines may not run softgels or patches. Match the supplier's line list to your roadmap, especially if you plan to extend a brand across formats.
- In-house R&D. A team that develops roughly 20 new products a year and holds patents is doing formulation as a discipline, not as an occasional favor.
- Cleanroom class. 100,000-class clean workshops are appropriate for supplement and tea production; ask any supplier what class their rooms are.
- Dedicated QC. Ask how many QA/QC inspectors work on production. Two dedicated inspectors is a concrete, checkable answer.
- Export experience. A supplier shipping to 30+ countries already knows the documentation, labeling, and logistics requirements for your destination.
- Trade track record. Response time, on-time dispatch rate, review scores, and online order volume are observable signals. Ours: response within 4 hours, 99.5% on-time dispatch, 4.6/5 from 53 Alibaba reviews, US$140,000+ in online orders.
- MOQ flexibility. Retail-pack MOQs (from ~100–120 bags/boxes for tea; ~100–150 boxes for gummies/tablets) suit brand launches; bulk OEM is quoted per project for scaling buyers.
