Certifications & Quality Assurance

We prioritize color consistency, safety, and durability, with every tumbler undergoing rigorous testing to meet global standards:

● Food Safety Certifications: FDA (U.S.) and LFGB (EU) compliance for lead-free glass, ensuring no harmful chemicals leach into beverages or candle wax.

● Material Testing: Soda-lime glass is certified for thermal shock resistance (surviving 80°C temperature changes) and color fastness (resisting fading after 100+ dishwasher cycles).

● Factory Standards: Our production facility is ISO 9001 certified, with strict quality control from glass melting to color coating and finishing.

● Quality Control Process:

1. Color Uniformity Test: Each tumbler is inspected for consistent color saturation and transparency across the entire surface.

2. Seam Integrity Check: The one-piece construction is verified to eliminate sharp edges or manufacturing defects.

3. Stack Load Test: Tumblers are stacked with 7kg of weight to confirm stable stacking performance.

4. Final Audit: A 5% sample of each batch is inspected for dimensional accuracy, color fastness, and durability.

Customization & Production Process

We offer flexible customization tailored to decor, retail, and brand needs, with a focus on preserving color integrity:

● Custom Options:

o Visual Customization: Sandblasting (subtle logos/text), full-color UV printing, or matte glaze accents for bold contrast.

o Color Matching: Custom Pantone color development for bulk orders (minimum 3000 units).

o Packaging: Branded foam-lined gift boxes (for retail) or bulk stackable cartons (for commercial use).

● Production Workflow:

1. Design Confirmation: Our team reviews your artwork/color specs and provides free digital mockups to test customization placement.

2. Sample Making: Pre-production samples (tumbler + customization) are ready in 6–8 business days (custom samples incur a fee, refundable on orders ≥3000 units).

3. Mass Production: Glass is melted, colored, and formed into seamless cylinders, then customized via sandblasting or printing.

4. Final Quality Check: All units are verified for color consistency, customization durability, and thermal resistance.

5. Packaging & Shipping: Securely packed in foam-lined cartons to protect color surfaces and customization during transit.
