Explore our flagship double-walled vacuum tumblers and sports flasks engineered to rigorous EU compliance and food-grade quality standards.
A comprehensive technical evaluation of food-grade safety, vacuum insulation engineering, compliance standards, and OEM supply chain integration.
In the evolving landscape of global retail and institutional procurement, verifying safety, durability, and non-toxicity in personal drinkware has shifted from a competitive edge to an absolute legal prerequisite. When importing stainless steel water cups, insulated tumblers, and sport flasks into the European Economic Area (EEA) and associated international markets, compliance with CE Standards and European Food Contact Regulations (such as Regulation EC No 1935/2004 and Regulation EU No 10/2011) ensures that the products do not endanger human health or bring about an unacceptable change in the composition of the beverage.
A verified CE Certification Water Cups Manufacturer must demonstrate strict quality governance across all manufacturing stages—from raw metal slitting and deep drawing to vacuum pumping, electro-polishing, and final lid assembly. Wuyi Dongyi Dailysupplies Co., Ltd operates at the forefront of this industrial sector, serving global brands, retail chains, and Amazon private-label sellers with compliant, high-performance insulated vessels.
Information Gain Insight: Genuine CE compliance for stainless steel drinkware covers not only the metal shell but also the entire closure system (BPA-free Tritan/PP lids, silicone sealing rings, and decorative powder coatings), guaranteeing zero migration of heavy metals (such as Lead, Cadmium, or Nickel) into hot or acidic liquids.
Located in Wuyi County, Zhejiang Province, Wuyi Dongyi Dailysupplies Co., Ltd leverages the world's most concentrated and sophisticated stainless steel hardware supply chain. The Zhejiang drinkware manufacturing cluster accounts for over 70% of global thermal bottle production due to unparalleled vertical integration, advanced metallurgical engineering, and robust infrastructure.
Our facility integrates full-spectrum manufacturing capabilities that substantially reduce lead times and production costs while maximizing quality control:
Automated hydraulic deep-drawing and hydro-forming processes maintain consistent wall thickness (0.4mm to 0.6mm), eliminating structural micro-cracks and ensuring maximum impact resistance.
Our multi-stage continuous vacuum furnaces operate at temperature levels exceeding 1000°C, extracting gas molecules down to 10^-4 Pa for unmatched double-wall thermal insulation performance.
Robotic electrostatic powder coating, 3D UV printing, laser engraving, and thermal sublimation capabilities deliver vibrant, scratch-resistant finishes that conform to REACH and RoHS chemical standards.

Understanding shifting consumer behaviors, ESG compliance requirements, and OEM procurement workflows.
Driven by worldwide initiatives banning single-use plastics, consumer demand for durable stainless steel tumblers, skinny tumblers, and large-capacity outdoor flasks (such as 30oz, 40oz, and 64oz models) has surged exponentially. Global brands and importers require factory partners capable of continuous design innovation, such as multi-functional 2-in-1 sip/straw lids, ergonomic handles, and car-cup-holder friendly tapered bases.
Professional procurement teams prioritize manufacturers who deliver high information gain, transparent audit trails, and consistent production scalability. At Wuyi Dongyi Dailysupplies Co., Ltd, we accommodate diverse international procurement structures:
Custom Pantone color matching, 3D laser-engraved branding, customized retail packaging (color boxes, eco-friendly cylinder tubes), and seasonal aesthetic colorways.
FBA-compliant packaging, barcoding, high-demand trending designs (e.g., egg-shaped wine tumblers, skinny tumblers, hydra quencher insulated mugs), and rapid turnaround times.
Bulk logo customization, certified non-toxic food-grade compliance, high-volume capacity, and consolidated global shipping solutions.
A structured, quality-controlled process guaranteeing seamless delivery from concept to batch production.

Receive detailed transparent pricing, tooling estimates, and 3D-printed or physical stainless steel prototypes for fit, finish, and ergonomics evaluation.
Finalize technical data sheets (TDS), color codes (Pantone), logo placement (laser, silk-screen, UV), and custom artwork for retail packaging.
Automated pipe cutting, expand forming, double-wall welding, vacuum baking, electro-polishing, and surface spray coating under strict ISO9001 supervision.
100% online vacuum temperature testing, liquid leak verification, drop tests, and third-party laboratory sample verification for CE/LFGB compliance.
Palletization, FBA prep, global freight management (FOB, CIF, DDP), and ongoing technical support for future product revisions.
Direct answers regarding CE compliance, stainless steel metallurgy, minimum order quantities, and OEM capabilities.
CE certification for water cups and drinkware verifies that all raw materials (304/316 stainless steel, polypropylene, silicone gaskets, pigments) satisfy EU food safety requirements, specifically Regulation (EC) No 1935/2004 and German LFGB standards. It ensures zero toxic heavy metal leaching, BPA-free compliance, and safe contact with hot, cold, and acidic liquids.
Grade 304 (18% Chromium, 8% Nickel) offers superior corrosion resistance against oxidation, organic acids, coffee, and tea. Grade 201 contains higher manganese and lower nickel, making it prone to pitting corrosion and rust over extended use. Wuyi Dongyi uses 18/8 (304) or premium 316 steel for all inner walls to ensure lifetime food safety.
We provide full customization: custom Pantone color matching, powder coating, rubberized paint, gradient finishes, 3D printing, laser engraving, silk-screen logos, custom molded silicone boots, custom lid designs (straw, sip, flip-top), and custom packaging boxes.
Every single product passes through automated 100% online thermal insulation testing twice during manufacturing. The cups are exposed to infrared temperature sensors after vacuum baking; non-conforming units with heat dissipation issues are automatically rejected from the line.
Our standard MOQ is typically 500 to 1,000 pieces per color/design for custom orders, while stock models with custom logos can be accommodated in smaller quantities. Mass production lead time ranges between 20 to 35 days depending on design complexity and order volume.
Yes. By utilizing specialized high-adhesion powder coating technology and electro-polished interior walls, our premium tumblers withstand commercial dishwasher cycles without paint peeling, logo fading, or seal degradation.
