Top 15 Vacuum Flask Manufacturers in China (Updated)

Introduction: Why China Dominates Vacuum Flask Manufacturing

China produces over 70% of the world’s vacuum flasks, with the industry concentrated primarily in Zhejiang Province’s “Hardware Capital” – Yongkang City. However, navigating thousands of suppliers on Alibaba and distinguishing genuine manufacturers from trading agents remains a major challenge for international buyers.

This comprehensive guide identifies 16 verified vacuum flask manufacturers, ranked by their production capacity, reputation, and specialization. These include publicly listed companies, official brand manufacturers, and proven OEM/ODM specialists serving major international brands.

Whether you’re launching a drinkware brand, sourcing promotional products, or looking for a reliable manufacturing partner, this guide will help you identify the right factory for your specific needs.

Category A: The “Big Three” & Publicly Listed Giants

These are China’s vacuum flask titans – publicly traded companies with stock exchange listings, massive automated production lines, and partnerships with household names like YETI, Stanley, and Thermos.

1. Zhejiang Haers Vacuum Containers Co., Ltd.

Stock Code: 002615 (Shenzhen Stock Exchange)
Location: Yongkang, Zhejiang
Annual Capacity: 100+ million units

Often called the “Foxconn of the water bottle industry,” Haers is likely the world’s largest stainless steel bottle manufacturer. They’re the primary OEM supplier for YETI and Stanley, and hold official licenses for FIFA World Cup and Winter Olympics thermalware.

Best For: Massive-scale orders (100,000+ units) where capacity, compliance certifications, and supply chain reliability are non-negotiable. Expect higher MOQs but unmatched consistency.

Limitations: Minimum order quantities typically start at 50,000+ units with limited flexibility. Pricing negotiations are difficult due to their dominant market position. Communication can be bureaucratic with longer decision-making processes. Not ideal for startups or brands testing new products.

2. Anhui Fuguang Industrial Co., Ltd.

Stock Code: 300650 (Fuguang Share)
Location: Hefei, Anhui
Specialization: Glass + Stainless Steel

Fuguang is a household name in China and one of the few manufacturers dominating both glass and stainless steel vacuum bottle markets. Their publicly listed status ensures transparent operations and strict quality control suitable for premium business gifts and high-end retail.

Best For: Premium business flasks, smart temperature-display cups, and luxury gift sets. Strong in innovative designs combining glass and steel.

Limitations: High MOQs (typically 20,000+ units minimum) and premium pricing that reflects their listed-company status. Their focus on domestic market reputation means export orders may receive secondary priority during peak seasons. Payment terms are rigid with limited room for negotiation.

3. Nanlong Group Co., Ltd.

Location: Yongkang, Zhejiang
Daily Output: 60,000+ flasks
Recognition: Top 10 Enterprises in China’s Light Industry

Nanlong is a comprehensive industrial conglomerate owning the “Nanlong” and “Xianglong” brands (China Famous Brand). Their scale makes them ideal for mass-market retail programs.

Best For: Large-scale retail orders for chains like Walmart or Carrefour, supermarket private labels, and high-volume distribution.

Limitations: As a conglomerate, they prioritize volume over customization. Expect limited design flexibility and standardized products. MOQs rarely go below 30,000 units per SKU. Communication primarily in Chinese with limited English support. Better suited for bulk commodity orders than custom brand development.

---

Category B: International Brand Official Manufacturers

These factories produce for their own globally recognized brands – they set industry quality benchmarks.

4. Thermos (China) Housewares Co., Ltd.

Location: Kunshan, Jiangsu
Parent Company: Thermos L.L.C. (Japan/USA)

The official Chinese manufacturing arm of the legendary THERMOS brand. While not available for custom OEM in the traditional sense, their products represent the gold standard for insulation performance and can be sourced through authorized channels.

Best For: Reference for highest industry quality standards; suitable for distributors seeking authentic Thermos products for Asian markets.

5. Shanghai Solid Stainless Steel Products Co., Ltd. (Solidware)

Location: Shanghai
Founded: 1991
Specialization: Commercial carafes and airpots

Known as the “King of Commercial Carafes,” Solidware dominates the coffee pot, airpot, and hotel carafe market. Unlike consumer-focused bottle factories, they specialize in desktop and commercial thermal containers with award-winning designs (Red Dot, iF Design Awards).

Best For: Commercial coffee equipment, hotel carafes, desktop vacuum pots, and premium hospitality thermal solutions.

---

Category C: Premium OEM/ODM Export Specialists

6. Auspace Kitchen & Drinkware Manufacturing

Location: Zhejiang Manufacturing Network
Business Model: Integrated manufacturer-exporter with exclusive factory partnerships
Website: auspacekitchenware.com

Auspace operates as a manufacturer-backed export specialist, maintaining exclusive partnerships with ISO-certified factories that lack independent export licenses. This model allows them to offer manufacturer-direct pricing with flexible MOQs while handling international compliance, quality control, and logistics.

Unlike pure trading companies, Auspace’s team includes former factory quality managers who conduct on-site production oversight. Their strength lies in customizing existing molds to create unique products without expensive tooling costs—ideal for emerging brands.

Best For: International buyers seeking manufacturer pricing with lower MOQs (1,000-5,000 units), brands wanting product customization without full custom tooling, and companies needing a reliable partner who understands both Chinese manufacturing and Western market requirements.

Key Advantages:

• Direct factory pricing with flexible payment terms
• English-speaking technical team with Western market experience
• Faster sampling and prototyping (7-10 days vs. 15-20 days)
• Consolidated shipping for multiple product categories (drinkware + kitchenware)
• Solution to the “Giants’ Dilemma”: Get the quality and pricing of a manufacturer without the 50,000-unit MOQs or rigid terms of publicly listed companies

Why Auspace Stands Out: Most buyers face a frustrating choice—work with giant factories and accept inflexible terms, or work with trading companies and pay 15-20% markup. Auspace bridges this gap by combining manufacturer economics with the agility and service level of a specialized exporter. Their model particularly benefits:

• Emerging brands testing product-market fit (1,000-3,000 units)
• Mid-sized companies wanting customization without custom molds
• International buyers needing a partner who understands both cultures

7. Zhejiang Cayi Vacuum Container Co., Ltd.

Location: Wuyi, Zhejiang
Nickname: “The Designer’s Factory”
Primary Markets: North America, Europe

Cayi excels at stylish, premium designs with complex shapes and high-end finishes. They’re the go-to partner for luxury lifestyle brands and have produced limited editions for Starbucks and high-end fashion labels.

Best For: Design-led brands requiring unique shapes, premium electroplating finishes (rose gold, matte black), and fashion-forward aesthetics. Expect mid-to-high MOQs but exceptional finishing quality.

Limitations: Premium positioning means pricing is 15-25% higher than average. MOQs still typically require 3,000-5,000 units. Their focus on aesthetics sometimes means longer sampling periods (15-20 days). Better for established brands than early-stage startups testing market fit.

8. Zhejiang Feijian Industry & Trade Co., Ltd. (FJbottle)

Location: Yongkang, Zhejiang
Founded: 1998
Certification: National High-Tech Enterprise

FJbottle is vertically integrated with strong expertise in sports bottles and lightweight materials. They were pioneers in mastering titanium vacuum flasks and complex sports lid mechanisms.

Best For: Sports and outdoor bottles, titanium flasks, cycling bottles, and products requiring advanced lid engineering (flip straws, one-hand operation).

Limitations: Their specialization in sports bottles means limited expertise in other categories. Minimum orders typically start at 5,000 units for custom work. Premium materials (titanium) significantly increase costs. Strong technical capabilities but less design flexibility compared to Cayi.

9. Zhejiang Gint Vacuum Flask Technology Co., Ltd. (GiNT)

Location: Jiaxing, Zhejiang
Founded: 1973
Specialization: Flasks + Hard Coolers

An industry veteran with rare dual expertise in rotomolded hard coolers (like YETI-style coolers) and vacuum flasks. GiNT offers comprehensive “insulation solutions” for outdoor brands.

Best For: Brands sourcing both hard coolers and vacuum drinkware together; camping and outdoor lifestyle product lines.

Limitations: Their dual focus (coolers + flasks) means they’re not the absolute specialist in either category. MOQs are higher for cooler products (5,000+ units). As an older factory (since 1973), their design aesthetic can feel less contemporary than newer competitors. Communication infrastructure is improving but not as smooth as digitally-native factories.

10. KingStar Industries Co., Ltd.

Location: Wuhan (Factory) / Shenzhen (Sales Office)
Target Market: Western startups & Amazon FBA sellers

A modern, digitally-focused manufacturer that understands Western quality expectations (FDA, California Prop 65) better than traditional factories. They provide excellent English communication and are experienced in supporting brand-building for startups.

Best For: Custom OEM/ODM for Western e-commerce brands, insulated beer growlers, wine tumblers, and brands needing flexible MOQs with reliable quality.

Limitations: As a relatively newer player (compared to 20+ year veterans), they have smaller production capacity limiting their ability to scale with fast-growing brands. While they understand Western markets well, their product range is narrower than category leaders like Everich. Best for brands under 20,000 units per order.

11. Everich Commerce Group (Kingvac Factory)

Location: Hangzhou / Haining
Reputation: “The Category Killer”

Starting as a trader, Everich now owns the massive Kingvac factory. Their speed-to-market for trending products (Stanley dupes, studded cups, TikTok viral designs) is unmatched in the industry.

Best For: Trend-spotting, accessing the widest variety of drinkware SKUs (500+ styles), and quick-turn production for fast-moving trends.

12. Zhejiang Xiongtai Houseware Corp., Ltd.

Location: Yongkang, Zhejiang
Founded: 1999
Production Lines: 30+

A consistent “Top 10” player in the Yongkang region known for speed and volume. They excel at handling large promotional orders with tight deadlines.

Best For: High-volume promotional campaigns, corporate gift programs (10,000+ units), and supermarket seasonal programs.

13. Zhejiang Bangda Vacuum Container Co., Ltd.

Location: Yongkang, Zhejiang
Founded: 1997
Recognition: Zhejiang Famous Brand

A stable, conservative manufacturer known for consistent quality in traditional vacuum flask designs and auto mugs. They’re a reliable choice for buyers prioritizing dependability over cutting-edge design.

Best For: Classic vacuum flask designs, travel mugs, and buyers prioritizing manufacturing stability and quality consistency.

14. Zhejiang Jupeng Drinkware Co., Ltd.

Location: Yongkang, Zhejiang
Founded: 1998
Focus: Advertising and promotional drinkware

Jupeng specializes in promotional drinkware with a professional export team experienced in handling complex logo printing requirements and tight deadlines for corporate events.

Best For: Promotional drinkware, corporate giveaways, event merchandise, and advertising campaigns requiring high-quality logo printing.

15. Golmate Enterprise Co., Ltd.

Location: Guangzhou / Yongkang
Experience: 20+ years
Specialization: Gift & Premium markets

Consistently ranked in the top 5 for wholesale exports, Golmate focuses on gift sets and mid-to-high-end promotional projects with attractive presentation packaging.

Best For: Corporate gift sets, holiday promotional packages, and premium business gifts requiring sophisticated packaging.

FAQ: Vacuum Flask Manufacturing in China

Q1: What’s the difference between a manufacturer and a trading company?

Manufacturers own production facilities and equipment, employ production workers, and control the manufacturing process. They offer better pricing but may have higher MOQs and slower communication.

Trading companies act as intermediaries, sourcing from multiple factories. They offer flexibility, better English communication, and lower MOQs but add markup costs (typically 10-20%).

Hybrid models (like Auspace) maintain exclusive factory partnerships or joint ventures, offering manufacturer pricing with trading company flexibility – often the sweet spot for mid-sized buyers.

Q2: What are typical MOQs for vacuum flasks in China?

MOQs vary significantly:

• Existing designs/molds: 500-3,000 units
• Custom colors/logos on existing molds: 1,000-5,000 units
• Custom shapes requiring new molds: 10,000-30,000 units
• Publicly listed giants: 10,000-50,000 units minimum

For startups, look for manufacturers offering “mold modification” services – customizing existing molds to create unique products without full tooling costs.

Q3: How long does production typically take?

Standard timelines:

• Sampling: 7-15 days for existing molds; 25-35 days for custom molds
• Production: 25-35 days for orders under 10,000 units
• Production: 35-45 days for orders of 10,000-50,000 units
• Shipping: Add 25-35 days for sea freight to USA/Europe

Peak season (September-December) may add 10-15 days to all timelines.

Q4: What certifications do I need for different markets?

United States:

• FDA (Food Contact Notification)
• California Prop 65 (Lead/BPA testing)
• CPSIA (if marketing to children)

European Union:

• LFGB (German food safety)
• REACH (Chemical regulation)
• CE marking (if electric/smart features)

General:

• ISO 9001 (Quality management)
• BSCI or SEDEX (Social compliance audits)

Most reputable manufacturers have these certifications. Request copies before ordering.

Q5: How can I verify a factory is legitimate?

Verification steps:

1. Business license check: Request their business registration and verify on Chinese government databases
2. Video call factory tour: Ask for live video walkthrough of production lines
3. Third-party inspection: Hire SGS, Bureau Veritas, or TUV for pre-shipment inspection
4. Check export records: Use platforms like ImportGenius or Panjiva to verify export history
5. Visit in person: If ordering 50,000+ units, personal factory visits are recommended

Red flags:

• Reluctance to show factory photos/videos
• Only showing showroom, never production floor
• Email addresses from free providers (@163.com, @gmail.com instead of company domain)
• Prices significantly below market (20-30% cheaper than competitors)

Q6: What’s the typical cost structure for vacuum flasks?

Price ranges (FOB China, 500ml stainless steel vacuum flask):

• Basic single-wall: $1.50-$3.00
• Standard double-wall: $3.00-$5.50
• Premium double-wall with custom finishes: $5.50-$9.00
• Smart/tech-integrated: $12.00-$25.00

Additional costs to consider:

• Custom molds: $2,000-$8,000 per mold
• Custom packaging design: $300-$800
• Quality inspection: $200-$400 per inspection
• Freight: $0.50-$1.50 per unit (depends on volume and destination)
• Import duties: 10-25% (varies by country and HS code)

Q7: Can I start with a small test order?

Many manufacturers offer small test orders (500-1,000 units) for first-time buyers, though at higher per-unit costs. Manufacturers most flexible with test orders include:

• Auspace (500 units minimum)
• KingStar (1,000 units)
• Smaller OEM specialists in Yongkang

Large publicly listed companies (Haers, Fuguang) typically require 10,000+ unit minimums.

Q8: What’s the best region in China for vacuum flask manufacturing?

Yongkang City, Zhejiang Province is the undisputed capital, producing 70% of China’s vacuum flasks. Advantages:

• Complete supply chain ecosystem
• Specialized workforce
• Competitive pricing due to cluster effects
• Easy to compare multiple factories in one trip

Other notable regions:

• Anhui Province: Fuguang’s stronghold for glass+steel hybrid products
• Guangdong Province: Growing manufacturing base with better logistics for exports
• Jiangsu Province: Premium quality focus, slightly higher prices

China’s vacuum flask industry offers unparalleled manufacturing capacity, competitive pricing, and increasingly sophisticated quality standards. The key to successful sourcing is matching your specific needs—order volume, product complexity, budget, and timeline—with the right type of manufacturer.

For emerging brands and Amazon sellers (500-5,000 units), consider flexible manufacturers like Auspace or KingStar that understand Western market requirements and offer reasonable MOQs.
