About Welong
We are a bubble tea ingredient manufacturer based in Chengdu, China. Our mission is to reset the standard for bubble tea's core ingredient — the pearl.
Specialising in pearl milk tea innovation
Welong International Trading (惠尔隆国际贸易(成都)有限公司) was founded in Chengdu, a city with one of the world's most competitive beverage and food-innovation scenes. We focus on a single category and go deep: the tapioca pearl.
Our instant tapioca pearls are the result of seven years of dedicated research into texture, shelf life and convenience, carried out by a team of more than 30 specialists including five food-science PhDs. The work has produced six national invention patents and an independently developed automated production line.
Everything we make is designed for one purpose: to let businesses anywhere serve genuine, chewy, shop-quality bubble tea without the cooking step that traditional pearls demand.
The Facts Behind the Brand
Pharmaceutical-grade cleanrooms
Our cleanroom production workshops are built to GMP (Good Manufacturing Practice) standards, with hygiene levels reaching pharmaceutical-grade requirements. We control air cleanliness, personnel hygiene and equipment sanitation throughout production, so the microbiological standards of our ready-to-use tapioca pearls significantly exceed conventional food-industry benchmarks.
- ISO Class 8 cleanroom (Class 100,000 pharmaceutical-grade)
- Independently developed automated production line
- Regularly audited by internationally recognised third parties
- Batch traceability and COA available per shipment
Three Commitments
Research first
We do not reformulate to chase cost. Texture, safety and shelf life are decided in the lab before they reach the production line.
Partner, not just supplier
From flavour selection to artwork in your market's language, we work as an extension of your product team.
Built for export
Documentation, certification and logistics support are part of the product, not an afterthought.
