Explore our enterprise-grade product catalog engineered with food-grade 304/316 stainless steel, double-wall vacuum isolation, and stylish ergonomic aesthetics tailored for international wholesale distributors and brand owners.
The international beverage container market is experiencing a profound paradigm shift. Traditional ceramic and glass tea cups, while aesthetically pleasing, present distinct vulnerabilities in commercial scaling: high breakability, zero thermal isolation, and significant supply chain loss rates. Today’s international corporate buyers—spanning retail brands, hospitality conglomerates, and corporate gifting specialists—are demanding beautiful tea cups that fuse aesthetic elegance with high-performance thermal insulation.
According to global retail market intelligence, demand for double-walled, vacuum-insulated stainless steel tea cups and tumblers has surged by 14.2% year-over-year. Buyers across North America, Europe, South America, the Middle East, and Southeast Asia are shifting sourcing operations toward certified Chinese manufacturers capable of offering turn-key OEM/ODM custom solutions, strict food-grade compliance, and scalable automated production.
Utilizing copper-coated double-wall vacuum barrier technology to maintain hot tea temperatures above 68°C for 12 hours and cold brews below 8°C for 24 hours.
Manufactured strictly with 18/8 (SUS304) and medical-grade SUS316 stainless steel, totally free of BPA, phthalates, lead, and toxic heavy metals.
Offering high-durability powder coating, UV gradient printing, 3D laser engraving, matte tactile finishes, and custom ergonomic lid systems.
To assist global procurement officers and brand directors in making data-driven sourcing decisions, our engineering team has benchmarked key material specifications used across various insulated tea cup manufacturing processes.
