What should I do if the cup leaks?

First, check if the lid gasket is properly installed, intact, or if the lid is tightly screwed. If the gasket is damaged, contact customer service for replacement; if the leakage persists, apply for after-sales inspection.

AI-Powered supplier vetting

SummaryThe supplier is a limited company with 145 employees and a 65,252 m² manufacturing site, producing drinkware, barware, and related products. It has extensive production-line coverage, inventory capability, flexible customization, quality assurance procedures, complaint-handling and corrective-action records, and ERP-based operational management. Export orientation is strong, with 90% of sales from exports and 20 years of export experience. However, the supplier has no valid manufacturing-capacity contract with its related subcontractor, no valid import/export license, no overseas warehouses, agents, branches, or showrooms, and no offline trade-show participation. R&D and innovation evidence is weak: it does not provide ODM, SDK, 3D design, or professional technical services and reported no new products in the past year. Material traceability is also absent. Financial credibility, certifications, and customer cases cannot be adequately assessed from the provided information.

Supplier typeThe supplier is identified as a limited company, independent of a larger corporate group, with 145 employees and a manufacturing site of 65,252.0 m². Its stated commercial activities cover sporting goods and recreation, bags, cases and boxes, and light industry and daily-use products, with product keywords centered on drinkware and pet bowls.

After-Sales capabilityThe supplier has documented and followed procedures for handling customer complaints and corrective/preventive actions, and it offers inventory capability and multiple quotation and payment options. Its service reach is limited because it has no overseas warehouse, overseas agents or branches, overseas showroom, or stated overseas-service countries.

R&D capabilityInnovation-related capability is explicitly limited: the supplier does not provide ODM services, SDK support, 3D software design, or professional technical-supplier services, and it reported no new products during the previous year. Flexible customization is available, but the evidence does not demonstrate strong independent innovation.

Production capacityThe supplier has a broad production setup including pipe pulling, injection molding, metalworking, welding, grinding, polishing, vacuum, spray painting, spray coating, and packing lines, supported by a 65,252.0 m² facility and 145 employees. It has inventory capability, finished-product inspection instructions that are uniformly followed, quality assurance, ERP integration, and 20 years of export experience, although no valid manufacturing-capacity contract exists with its related subcontractor and no valid import/export license is reported.

Customization capabilityThe supplier explicitly offers flexible customization through its design and R&D-related services. However, it does not provide 3D software design, ODM, SDK, or professional technical services, indicating that customization is available but may not include advanced product-development support.

Product Q&A

Q:How long is the heat/cold retention time?

Regular models provide 6-12 hours of heat retention and 12-24 hours of cold retention. The specific duration may vary slightly depending on the product model, capacity, and usage environment.

Q:What kind of stainless steel is used? Is it safe?

The core material is food-grade 304 or 316 stainless steel, which meets national food contact safety standards. It is odorless, does not leach harmful substances, and is safe and reliable.

Q:Does the plastic material meet food-grade standards?

All plastic cups are made of food-grade safe materials such as PP and Tritan, which have passed food contact plastic testing. They are high-temperature resistant, not easy to deform, and can be used with confidence.

Q:How should I handle the cup before first use?

First, clean the inner liner and outer surface with warm water and a small amount of neutral detergent, then rinse thoroughly with clean water repeatedly, and use it after drying.

Q:Can the product be heated in a microwave or cleaned in a dishwasher?

Stainless steel cups/bottles cannot be heated in a microwave oven. Most styles are not recommended to be cleaned in a dishwasher to avoid damaging the coating or seals; hand washing is recommended.
