9. Frequently Asked Technical Questions (FAQ)

Q1: What is Borosilicate Glass, and why is it used for double wall insulated glass coffee mugs?

Borosilicate Glass, defined by DIN ISO 3585, is a high-purity glass with excellent thermal shock resistance and chemical stability. It ensures these mugs are safe for rapid temperature changes—microwave, freezer, or boiling water—making them superior for both safety and durability compared to regular soda-lime glass.

Q2: Are these mugs truly vacuum insulated?

Yes, quality double wall insulated glass coffee mugs feature either a vacuum or air gap sealed between two glass walls, dramatically reducing heat conduction via physical separation. Some cost-down models may use an air gap only; always check for vacuum-sealed certification in specs.

Q3: What industry safety certifications do Yinto mugs offer?

All mugs conform to FDA, LFGB, and SGS food-contact standards. The manufacturing plant is ISO 9001:2015 quality system certified, with batch-level QA and destructive testing per ANSI Z97.1.

Q4: What's the recommended care—are the mugs dishwasher and microwave safe?

Double wall insulated glass coffee mugs (borosilicate) are safe for both dishwasher and microwave, provided there is no metal décor. The mugs have passed 20,000+ industrial dishwasher cycles without clarity loss or vacuum seal compromise.

Q5: Can personalised double wall coffee cups be made with photo or color graphics?

Absolutely. Using high-temperature decal/sublimation processes, virtually any color logo or photo can be permanently applied to the glass wall. Laser engraving is recommended for logo longevity in hospitality uses.

Q6: What's the typical lead time from order to delivery? Can I order smaller MOQs?

Standard lead time for non-customized mugs is 7-10 days for orders <2000 units. Customization (engraving/packaging/shape) adds 5-15 working days. MOQ drops to 60-100 pc for stock shapes, 200~500 pc for custom runs.

Q7: What is the warranty and aftersales support?

B2B customers enjoy a 12-month product warranty (Yinto Glassware), covering seal failure/delamination. Customer Care supports both Taobao/B2B channels via phone & web chat, and batch-traceability assures efficient problem resolution.

10. Delivery Cycle, Warranty, and Support—What To Expect

Standard lead time: 7-10 days (in-stock); 14-20 days (custom shapes, large volumes)
Warranty: 12 months, full return/replacement for vacuum seal or finish defects
Aftersales: Multilingual support, batch tracking, dedicated account manager
Certifications available on request: ISO, FDA, LFGB, EN standards compliance
