Explore our flagship 18/8 food-grade stainless steel vacuum insulated coffee mugs, tumblers, and sports flasks engineered for global wholesale and OEM distribution.
Located in the renowned hardware manufacturing hub of Wuyi County, Zhejiang Province, China, Wuyi Dongyi Dailysupplies Co., Ltd. stands as a premier global benchmark in the production, research, and technical development of food-grade stainless steel tumblers, oversized coffee mugs, vacuum bottles, and industrial-grade drinkware containers.
Our industrial complex integrates advanced automated double-walled vacuum insulation lines, micro-plasma laser welding systems, and rigorous robotic QA testing setups. Specializing in high-capacity vessels ranging from 20oz to 64oz, we empower global brands, Amazon sellers, outdoor outfitters, and corporate clients with market-leading OEM and ODM solutions.
Empirical evidence of enterprise manufacturing excellence, international supply capacity, and quality management performance.
The global oversized hydration market is undergoing a structural transformation driven by wellness economics, ergonomic innovation, and sustainable consumer shifts.
Modern consumer behavior in North America, Western Europe, and Australasia has pivoted from single-serve disposable cups to high-capacity (30oz to 64oz) reusable thermal vessels. Driven by active lifestyle trends, desk-side coffee replenishment reduction, and all-day outdoor activities, the demand for high-capacity insulated mugs equipped with handles and straw lids has grown exponentially year-over-year.
International importers must strictly adhere to food contact regulations. Our production matrix strictly complies with US FDA 21 CFR 175.300, European LFGB, EC 1935/2004, and CE standards. All raw materials undergo heavy metal leaching assays, ensuring zero lead content in copper vacuum sealing processes and 100% BPA-free polymer accessories.
E-commerce platforms like Amazon, Shopify, and TikTok Shop have created aggressive demand cycles for unique visual aesthetics—such as pastel powder coatings, gradient electroplating, 3D laser engraving, and custom silicone boot accessories. Wuyi Dongyi provides agile OEM/ODM customization with low MOQs and rapid prototyping.

Critical insights for wholesale procurement managers, product development directors, and enterprise importers.
SUS304 stainless steel contains 18% chromium and 8% nickel, creating an ultra-stable austenitic crystalline structure. This metallurgic composition resists acidic beverages (such as black coffee, citrus infusions, and tea) without leaching metallic ions into liquids. Combined with our electropolished interior finish, it prevents bacteria accumulation and eliminates residual taste transfer between drinks.
Heat transfer occurs through conduction, convection, and radiation. Our double-walled manufacturing process evacuates air between the inner and outer stainless steel walls to a high-vacuum state (10^-4 Pa), eliminating conduction and convection. Furthermore, we coat the exterior of the inner wall with a micro-thin layer of copper, which acts as a thermal mirror to reflect infrared radiation back into the vessel.
We offer extensive OEM/ODM customization options including thermosetting powder coating (matte, glossy, or textured), electroplating (metallic/mirror effect), 3D UV digital printing, silk-screen printing, and high-precision laser engraving. Furthermore, custom pantone color matching is supported alongside custom molded silicone boots, custom handle grips, and custom retail gift boxes.
Yes, all lid components are manufactured using virgin, food-grade Tritan (Eastman copolymer) or polypropylene (PP), paired with food-grade silicone seals. Our multi-functional 2-in-1 sip and straw lids undergo 100% pressure leak testing and are fully certified under US FDA 21 CFR, EU LFGB, and CE compliance frameworks.
Standard catalog production orders start at low MOQs (typically 500 to 1,000 units depending on color requirements). Custom tooling or bespoke lid development projects take approximately 15-20 days for mold engineering and sample confirmation, followed by mass production lead times of 25-30 days.
