Dongyi
Top-rated vacuum insulated drinkware engineered for Vietnam's tropical climate, commercial hospitality, and active lifestyle segments.
An in-depth analysis of consumer shifts, climate-induced demand, and industrial procurement trends across Hanoi, Ho Chi Minh City, and Da Nang.
With Vietnam's average annual temperature exceeding 27°C and humidity often surpassing 80%, ice longevity is paramount. Urban commuters and outdoor workers require double-walled 18/8 vacuum insulation capable of maintaining sub-5°C liquid temperatures for up to 36 hours despite oppressive ambient heat.
Vietnam boasts one of Asia's most vibrant coffee cultures (Highlands Coffee, Phúc Long, Cà Phê Muối trends). The rapid transition toward reusable travel tumblers (30oz & 40oz Quenchers) is driven by environmental awareness and brand promotion via custom-printed corporate drinkware for local chains.
Platforms such as Shopee Vietnam, Lazada VN, and TikTok Shop VN have seen a 145% YoY surge in vacuum flask searches. Concurrently, industrial zones in Bắc Ninh, Bình Dương, and Đồng Nai are ordering massive volumes of branded hydration gear for workforce gifting programs.

Turnkey solutions for corporate events, industrial park anniversaries (Samsung Vietnam, Foxconn Vietnam supplier networks), and bank VIP gifts. Includes laser-etched corporate logos, custom sleeve packaging, and silk-screened gift sets.
For global brands seeking proprietary vessel shapes or innovative multi-drinking lids. Our in-house R&D team provides 3D CAD rendering, rapid prototyping within 7 days, and full production mold tooling within 25 days.
Pioneering sustainable metallurgical engineering, ultra-light vacuum structures, and eco-conscious coating solutions.
In response to global carbon tax initiatives and ESG mandates adopted by multinational corporations operating in Vietnam, our factory is transitioning toward Post-Consumer Recycled (PCR) 304 stainless steel. This cuts carbon footprint by 65% while retaining identical tensile strength, rust resistance, and thermal efficiency.
Through advanced spin-thinning manufacturing technologies, we have reduced the inner stainless steel wall thickness down to 0.4mm without sacrificing structural stability against drop impacts. This innovation delivers a 25% lighter bottle, perfect for high-mobility sports, hiking, and daily scooter commuting in Vietnam.
Ensuring zero-friction customs clearance and maximum tariff advantages under regional trade agreements.
Under the ASEAN-China Free Trade Area (ACFTA), we issue official **Form E Certificates of Origin**. This enables Vietnamese buyers to import stainless steel flasks and vacuum tumblers under HS Code 9617.00 with reduced tariff rates (typically 0% to 5%), significantly maximizing profit margins compared to standard MFN tariffs.
We provide full raw material traceability and heavy metal lab testing (Lead, Cadmium, Chromium release tests) required by the Vietnam Ministry of Health (Bộ Y Tế) for food-contact items. All plastics and silicone gaskets are strictly BPA-Free and food safe.
We manage direct sea freight shipments from Ningbo/Shanghai ports to **Hải Phòng Port** (North Vietnam, 4-7 days transit) and **Cát Lái Port / HCMC** (South Vietnam, 5-9 days transit), as well as direct cross-border trucking via Lạng Sơn / Móng Cái border gates for urgent production deadlines.
From initial technical inquiry to door-to-door delivery in Vietnam, our standardized workflow guarantees transparency and zero delays.

Our standard Minimum Order Quantity (MOQ) for stock colors with custom laser-engraved or screen-printed logos starts at 500 units. For custom Pantone color spraying, powder coating finishes, or customized retail packaging boxes, the MOQ is generally 1,000 to 2,000 units per model.
The Form E Certificate of Origin issued under the ASEAN-China Free Trade Agreement (ACFTA) allows Vietnamese customs authorities to grant preferential tariff rates on our stainless steel drinkware. Importing under HS Code 9617.00 reduces import duties down to 0% - 5%, significantly lowering your landed import costs.
All vessels produced by Wuyi Dongyi Dailysupplies Co., Ltd utilize food-grade SUS304 (18/8) or SUS316 stainless steel. Our products comply strictly with Vietnam's QCVN 12-3:2011/BYT health standards, US FDA 21 CFR regulations, European LFGB standards, and CE certification for food safety contact.
Standard mass production takes approximately 15 to 25 days post sample approval. Sea freight from Ningbo to Hải Phòng Port (for Hanoi) takes 4–7 days; to Cát Lái Port (Ho Chi Minh City) takes 5–9 days. Urgent orders can be dispatched via cross-border land freight within 3–5 days.
Yes. We offer complete custom packaging solutions, including rigid luxury gift boxes, printed cylinder tubes, craft paper cartons, and velvet bags. We can also include custom printed cards, instruction booklets, and co-branded accessories (straw cleaners, silicone boots).
Every single bottle undergoes a 3-stage automated temperature inspection before coating and assembly. Vessels pass through infrared thermal imaging testing to guarantee zero heat dissipation across the double wall vacuum structure before leaving our factory line.
