About Wuyi Ronchine

A Drinkware Manufacturing Partner Built for Global Buyers

Wuyi Ronchine Industry & Trade Co., Ltd. is based in Wuyi County, Jinhua, Zhejiang, a region with a long tradition of cup and household goods production. The company was founded to take our affiliated manufacturers directly to international markets, so buyers deal with the factory team rather than layers of middlemen.

We own the Jass Life and YAMI brands, and every product starts from one brief: good-looking, easy to use and fun. That retail-first mindset is what our OEM and ODM clients rely on when they need designs that sell through on shelves and social media.

Contact Our Team

Are you a manufacturer or a trading company?

Wuyi Ronchine Industry & Trade Co., Ltd. is the export company founded to serve our affiliated drinkware factories in Wuyi, Zhejiang. You work with one English-speaking team that coordinates molds, production and QC directly on the factory floor. On-site visits and live video audits are welcome.

What customization options do you offer?

Logo printing, Pantone color matching, gradient spraying, electroplating, rhinestone (drill sticker) decoration, custom lids and straws, set combinations, and branded gift boxes or retail packaging.

What is your minimum order quantity?

MOQ depends on the model and decoration method. Existing models in stock colors with a logo print allow lower quantities than fully custom molds. Share your target quantity and market, and we will suggest the most efficient option.

How long do sampling and mass production take?

Custom samples generally take 7–15 days. Mass production generally takes 25–45 days after sample approval, depending on quantity, decoration complexity and season. Exact timelines are confirmed in writing before production starts.

Are your cups food-safe for export markets?

We use food-contact materials such as PP, AS, Tritan copolyester and 304 stainless steel, with BPA-free options. Third-party testing to FDA, LFGB or EU 10/2011 requirements can be arranged through accredited laboratories, and certificate copies are available on request.

Every Detail Reflects Quality. Let's Build Your Next Bestseller.
