Explore our flagship lineup of CE-marked, food-grade double-wall vacuum insulated tumblers, mug water containers, and travel flasks. Engineered for international retail brands, corporate buyers, and global distributors.
The global reusable hydration market has undergone a paradigm shift. Hydration hardware—encompassing stainless steel mug water vessels, vacuum insulated travel tumblers, and high-capacity hydration bottles—has transitioned from simple functional commodities to high-precision engineering products. Driven by stringent European environmental directives, strict food contact material safety frameworks, and modern consumer preferences for ergonomic, high-performance drinkware, global sourcing directors are prioritizing certified quality over baseline production cost.
For enterprise buyers across North America, Europe, the Middle East, and Asia-Pacific, securing a reliable OEM/ODM partner capable of producing CE-certified mug water containers is critical. CE certification serves as a baseline guarantee of physical safety, raw material compliance, and legal marketability within European and international regulatory landscapes. Modern manufacturing plants must integrate raw material traceability, advanced thermal barrier engineering, automated surface treatment, and clean-room assembly to meet the standards demanded by major global retail brands.
Understanding the regulatory architecture governing mug water products and stainless steel vessels is paramount for brand protection and frictionless international trade. When imported into the European Single Market or aligned global jurisdictions, stainless steel insulated drinkware must strictly conform to multi-tier safety standards covering chemical migration, heavy metal leaching, thermal stability, and structural safety.
Framework Regulation (EC) No 1935/2004 stipulates that materials coming into contact with drinking water and food must not transfer their constituents into food in quantities that endanger human health, bring about an unacceptable change in food composition, or cause deterioration in organoleptic characteristics.
Specific extractable heavy metal testing (Lead, Cadmium, Nickel, Chromium, Manganese) under dynamic thermal conditions. Austenitic 18/8 (SUS304) stainless steel inner liners undergo rigorous acid solution exposure to guarantee zero toxic element dissolution during prolonged hot beverage contact.
All plastic components (lids, handles, straws) and silicone sealing rings must be 100% BPA-Free, Phthalate-Free, and compliant with REACH SVHC (Substances of Very High Concern). Surface coatings undergo non-toxic powder coating validation to meet stringent EU safety norms.

Located in the industrial hardware hub of Wuyi County, Zhejiang Province, China, Wuyi Dongyi Dailysupplies Co., Ltd. stands as a premier manufacturer specializing in the research, development, and mass production of high-grade stainless steel tumblers, mug water containers, insulated sports bottles, travel mugs, and hydration jugs.
Our advanced facility integrates state-of-the-art metal hydroforming, precision laser welding, automated high-vacuum pumping lines, and eco-friendly powder coating clean rooms. Operating under a rigorous quality management framework, our professional R&D engineering team continuously innovates to deliver stylish, durable, and thermally efficient drinkware to the world's leading brands.
Our products are exported across key global commercial regions, including North America (USA, Canada), Western & Eastern Europe, South America, the Middle East, and Southeast Asia. We maintain long-standing supply partnerships with corporate importers, Amazon FBA brand aggregators, and retail chains.
From custom 3D industrial rendering, mold fabrication, and functional lid design to surface color matching (Pantone PMS, gradient sprays, water-transfer printing, 3D UV printing) and laser-etched branding, we turn client concepts into market-ready products.
Quality First, Service First. Every batch undergoes 100% two-stage thermal vacuum insulation testing, leak-proof pressure verification, coating cross-hatch adhesion testing, and dimensional tolerance inspection before leaving our factory floor.
Thermal insulation efficiency in modern mug water manufacturing relies on precision engineering principles. Below is an engineering overview of the double-wall vacuum structure manufactured at Wuyi Dongyi Dailysupplies Co., Ltd.
Austenitic grade 304 stainless steel containing 18% Chromium and 8% Nickel offers exceptional resistance against pitting corrosion, organic acid attack, and mechanical deformation. The inner wall is electropolished to prevent flavor retention and bacterial colonization.
Air between the inner and outer walls is extracted in high-temperature vacuum furnaces reaching 10-4 Pa pressure. A specialized chemical getter pill is inserted to absorb residual gas molecules over time, ensuring thermal stability across a 10-year lifespan.
To combat radiant heat transfer, the outer surface of the inner stainless steel wall is electroplated with a micro-thin copper coating. This copper layer acts as a thermal mirror, reflecting infrared radiation back into the vessel to preserve temperature.
We streamline international B2B procurement through a transparent, standardized manufacturing workflow that minimizes lead times and guarantees complete CE regulatory compliance.
As consumer preferences evolve and ESG (Environmental, Social, and Governance) commitments intensify worldwide, drinkware manufacturing is undergoing rapid technological innovation. Procurement managers must align with factories actively investing in next-generation manufacturing technology.
Transitioning to Post-Consumer Recycled (PCR) 304 and 316 grade stainless steel allows brands to reduce product carbon footprints by up to 60%. Certified recycled material chains guarantee eco-friendliness without compromising tensile strength or corrosion resistance.
To cater to specialty coffee and acidic tea drinkers, modern vacuum mugs feature micro-thin interior ceramic coatings. Applied via Plasma-Enhanced Chemical Vapor Deposition (PECVD), this layer eliminates metallic taste while remaining easy to clean.
Integration of low-power LED touchscreens in mug water lids allows real-time temperature sensing and hydration reminder alerts. Lids are built with IPX7 waterproof seals and rechargeable magnetic charging modules.

CE certification verifies that mug water products comply with mandatory European health, safety, and environmental protection standards. It ensures that materials coming into contact with food (EC 1935/2004) are chemically inert, free from harmful plasticizers (BPA/Phthalates), and structurally sound under everyday thermal stress.
18/8 stainless steel (304 grade) contains 18% Chromium and 8% Nickel, offering exceptional corrosion resistance and mechanical durability for water, coffee, and everyday beverages. Grade 316 stainless steel adds 2-3% Molybdenum, which increases resistance against chlorides and acidic liquids. Both materials are available for custom OEM production at Wuyi Dongyi Dailysupplies Co., Ltd.
We provide complete OEM/ODM customization options including matte/gloss powder coating, metallic electroplating, rubberized tactile paint, marble gradient water-transfer, high-definition 3D UV printing, silk-screen printing, and precision laser etching for corporate logos.
Our factory utilizes 100% automated two-step thermal testing. After vacuum furnace processing, every vessel undergoes infrared thermal imaging inspection to detect heat leakage. Units that fail to maintain specified thermal metrics are automatically rejected prior to surface finishing.
Standard production lead times range from 25 to 35 days post sample approval and deposit confirmation. MOQs vary from 500 to 3,000 units depending on the complexity of custom tooling, specialized color spraying, and packaging requirements.
