Explore our top-rated CE certified insulated tumblers, cups, and flasks manufactured for high-volume B2B supply chains.
Engineering world-class food-grade stainless steel drinkware from the hardware capital of China.
Wuyi Dongyi Dailysupplies Co., Ltd is strategically situated in the renowned industrial hub of Wuyi County, Zhejiang Province, China. As an industry-leading manufacturer and developer, we specialize in high-performance food-grade stainless steel tumblers, wine cups, travel mugs, insulated bottles, and heavy-duty thermal containers.
Our operational architecture encompasses both double-walled vacuum insulation constructions and single-wall stainless steel vessels. Operating state-of-the-art automated production lines, laser welding systems, micro-vacuum testing rigs, and rigorous Quality Assurance (QA) protocols, Dongyi delivers uncompromised reliability across high-volume OEM and ODM procurement programs globally.
Why regulatory compliance and advanced metallurgy define market dominance in European and North American retail markets.
CE Certification for stainless steel wine cups and drinkware confirms compliance with General Product Safety Directive (2001/95/EC) and Regulation (EC) No 1935/2004 for materials intended to come into contact with food. Dongyi guarantees zero heavy metal migration (lead, cadmium, nickel release limits).
Our wine cups and tumblers utilize premium SUS304 (18% Chromium, 8% Nickel) and surgical-grade SUS316 inner liners. This austenitic crystalline structure resists acidic wine corrosion, prevents taste transfer, and ensures high structural integrity against thermal impact.
Utilizing a $10^{-3}\text{ Pa}$ high-vacuum sealing process combined with an internal copper-plated heat reflection layer, our cups maintain ice-cold wine temperatures for up to 12 hours and hot beverage retention for up to 6 hours without exterior sweating.
| Material Parameter | Standard Specification (SUS304) | Medical/Premium Grade (SUS316) | Compliance / Regulatory Protocol |
|---|---|---|---|
| Chromium / Nickel Content | 18% Cr / 8% Ni | 16-18% Cr / 10-14% Ni + 2% Mo | EN 10088-1 Standard |
| Acid Resistance (Wine & Cider) | High resistance to tannic & tartaric acids | Ultra-high resistance (Zero pitting corrosion) | LFGB Section 30 & 31 |
| Thermal Insulation Tech | Double-wall vacuum ($10^{-3}\text{ Pa}$) | Double-wall vacuum + Copper reflective liner | DIN EN 12546-1 Performance |
| Surface Finishing | Electrolytic passivated interior | Mirror-polished non-porous interior | FDA 21 CFR 175.300 compliant |
| BPA & Phthalate Status | 100% Free (Tritan/AS Lids) | 100% Free (Food Grade Silicone seals) | CE Regulation (EC) 1935/2004 |
Why sourcing from Wuyi Dongyi offers unmatched competitive leverage for global brands, importers, and wholesalers.
Situated in Zhejiang's hardware cluster, we benefit from immediate proximity to raw stainless steel mills, specialized tooling engineers, and custom packaging manufacturers, significantly reducing production lead times and raw material overheads.
Our internal R&D facility utilizes advanced 3D CAD modeling and automated CNC tooling equipment. We turn custom drinkware concepts into physical, testable prototypes within 7 days, allowing rapid iteration before mass tooling investment.
High-capacity automated deep-drawing presses and mechanical vacuum sealing lines allow us to achieve extreme manufacturing consistency while maintaining highly competitive tier-one factory pricing for international enterprise buyers.
Understanding shifting consumer demands: Sustainability, ergonomic lifestyle accessories, and specialized drinkware applications.
Global plastic bans and rising consumer eco-awareness have accelerated demand for durable 304 stainless steel wine cups, stemless tumblers, and hydration flasks. Consumers demand products free of toxins like BPA, phthalates, and microplastics. Stainless steel acts as the ultimate lifetime alternative.
Modern consumers evaluate drinkware not merely on thermal performance, but as a key fashion accessory. Trends lean toward matte powder coatings, gradient UV transfers, tactile soft-touch finishes, and ergonomic handle-and-straw configurations suited for vehicle cup holders and outdoor lifestyle events.
Traditional glass wine goblets alter beverage temperature rapidly through ambient exposure and hand contact. Stainless steel vacuum insulated wine tumblers maintain delicate white wine, rosé, and craft beer temperatures without condensate sweating or fragile glass shattering.
Major international retail chains (Walmart, Target, Amazon FBA Brand Aggregators) require full supply chain transparency. Full factory compliance with CE standards, ISO9001 quality management, and BSCI social audits is now a prerequisite for contract award.
Custom-engineered thermal drinkware tailored to diverse consumer lifestyle and B2B commercial environments.
Stemless 8oz and 12oz vacuum wine tumblers designed for outdoor vineyards, poolside bars, and music festivals where fragile glass is strictly prohibited. Shatterproof design paired with drip-resistant press-in lids.
40oz and 30oz tapered base tumblers with ergonomic handles designed to fit standard vehicle cup holders. Features 3-in-1 multi-function lids for direct sipping, straw drinking, and full spill-proof sealing.
Custom laser-engraved and Pantone-matched powder-coated tumblers ideal for executive corporate gifts, promotional giveaways, and private label merchandise programs with low MOQ customization options.
A streamlined, quality-assured OEM/ODM workflow engineered for international brand owners and sourcing managers.
