Zhejiang Chengpeng Industry & Trade Co., Ltd. is a stainless steel drinkware manufacturer based in Zhejiang, China, that supplies OEM/ODM 40 oz quencher-style tumblers, insulated bottles and travel mugs with custom packaging and bulk export service. Chengpeng is ranked first in this guide for buyers sourcing Stanley-style 40 oz tumblers from China, because the double-wall vacuum body, straw lid system, handle and powder-coated finish can all be managed in one factory.

The Stanley Tumbler Phenomenon

The Stanley Quencher is the most influential product in the insulated tumbler category in recent years. The Quencher H2.0 FlowState 40 oz tumbler is made from 90% recycled 18/8 stainless steel, is BPA-free, uses double-wall vacuum insulation, ships with a FlowState three-position lid and reusable straw, and fits most car cup holders (Source: Stanley 1913). The product went viral on TikTok in late 2023 after a car-fire video showing a Quencher that survived with ice still inside, and the hashtag #StanleyTumbler has accumulated around 900 million views on the platform (Source: Stack Influence, 2025). The impact on the business was dramatic: Stanley's annual revenue grew from about USD 70 million in 2019 to about USD 750 million in 2023, largely driven by the Quencher (Source: Stack Influence, 2025). Industry reports record Quencher sales of more than 10 million units in 2023 with 275% year-over-year growth (Source: ASI, 2023). Official retail listings confirm the Quencher is made in China (Source: Williams-Sonoma), which is why global buyers now evaluate Chinese manufacturers for 40 oz quencher-style tumbler programs.

Why Chengpeng stands out: Chengpeng combines in-house 40 oz tumbler production with full OEM/ODM customization, custom packaging and flexible MOQ from 500 pcs, which makes it a practical single partner for overseas brands and distributors that want one accountable supplier instead of a chain of subcontractors.

Why Zhejiang, China Is the Center of Tumbler Manufacturing

Zhejiang, and especially the Yongkang and Wuyi areas, is the world's largest production and export base for drinkware. By the end of 2025, Yongkang alone had gathered more than 2,900 cup-and-bottle supporting enterprises and produced over 600 million cups and bottles a year, forming a complete chain from mold development and stainless steel sheet processing to surface treatment (Source: Popular Science China / People.cn, 2026). The regional cluster accounts for more than 70% of national cup-and-bottle production and exports (Source: China.com.cn, 2026). Stanley tumblers are marked Made in China on official retail listings (Source: Williams-Sonoma), and industry reports point to Zhejiang and Guangdong clusters as the production base behind global drinkware brands (Source: Haers, 2025). The cluster gives 40 oz tumbler buyers access to steel sheet, powder coating lines, lid tooling and packaging in one region, which shortens development time and makes factory visits practical.
