Import 550ml Stainless Steel Sport Bottle — Buy in wholesale FOB from Supplier in China

This 550ml stainless steel sport bottle features a double-wall vacuum-insulated construction with a cola-shaped silhouette, manufactured by Yongkang Han Kun Industrial Co., Ltd. in Yongkang, Zhejiang Province. The inner liner uses SUS304 (18/8) austenitic stainless steel, while the outer shell employs SUS201, a manganese-substituted grade with lower nickel content that reduces material cost while maintaining forming characteristics. The vacuum insulation layer minimises conductive heat transfer, with stated design intent for temperature retention of both hot and cold beverages during sports and commuting use. Capacity is confirmed at 550ml, with additional variants of 350ml and 500ml referenced in the supplier's specification set.

The material breakdown extends beyond the steel shell to include imported PP polypropylene for the base guard, upper frame, cap, cup cover, stopper, water inlet, and lanyard, selected for colourability and heat resistance above 100°C. The compression chamber uses PE polyethylene for recovery resilience, while ABS forms the cap button, cap ring, and tap pressure bar due to surface hardness and chemical resistance. Sealing relies on SI silicone rubber with stated resistance to thermal cycling and atmospheric ageing. The product claims ROHS compliance with explicit exclusion of lead, cadmium, mercury, and bisphenol A, though buyers should request current test reports with laboratory accreditation status.

Target buyers include sporting goods retailers, corporate wellness programmes, and promotional merchandise distributors requiring custom logo integration. Decoration methods offered encompass paper insert, PET insert, silk screen printing, and heat transfer printing, with colour matching to Pantone references. The 550ml capacity aligns with standard bicycle cage and automotive cup holder dimensions, though exact outer diameter should be confirmed against specific holder geometries. Sample lead time is stated at 7 days, with production payment terms of T/T or L/C at sight, though MOQ and production lead time beyond sample phase require direct negotiation with the Yongkang facility.

Yongkang Han Kun Industrial Co., Ltd. is based at No. 38, Yingui South Road, Huachuan Industrial Zone, Jinhua, Zhejiang 321300, China. The company carries a 'harbor' trust tier on its platform profile, with a response rate of 0.00 percent and zero recorded average response hours, indicating that proactive direct contact is likely necessary for reliable communication. Yongkang city is historically significant within China's hardware and metalwork manufacturing cluster, particularly for stainless steel drinkware, though this geographic concentration does not alone verify any individual supplier's capability.

The supplier profile does not disclose year of establishment, factory floor area, employee count, annual revenue, or export destination history, and these metrics should not be fabricated. What the listing does communicate is a detailed material specification with explicit grade call-outs for SUS304, SUS201, PP, PE, ABS, and silicone rubber components, suggesting a degree of technical documentation that buyers can validate through factory audit and sample testing. The presence of custom decoration options and multiple capacity variants indicates a flexible production setup, though this should be confirmed through site visit or third-party verification.
