In the US and European markets, "Flash Chilling" (pouring boiling water directly over ice) is a standard brewing practice. Our 3.3 Borosilicate glass is the only material that guarantees safety under these extreme thermal shocks (ranging from -20℃ to 150℃). Unlike soda-lime glass, it remains lead-free, cadmium-free, and won't cloud over time, maintaining a crystal-clear display for your cold brew products.

In a saturated global market, differentiation is the cornerstone of success for any brand. We offer comprehensive OEM/ODM services, supporting deep customization—from lid materials (such as 304 stainless steel, eco-friendly bamboo, or high-clarity silicone) to custom-colored silicone seals. Whether it’s laser-etched logos, silk-screen branding, or fully personalized gift packaging, our flexible Low MOQ solutions allow you to rapidly launch a distinctive product line and capture the competitive iced tea market.

For Amazon and Shopify sellers, shipping breakage is the biggest threat to margins. Our packaging is ISTA drop-test certified and compact, specifically designed to lower your FBA storage and fulfillment fees. We provide turnkey services, including SKU labeling and compliance marking, ensuring your inventory is ready for sale the moment it clears customs, enabling rapid turnover.

The heart of a high-performance iced tea maker lies in its filtration. Our 304 stainless steel infusers feature precision laser-cut micro-mesh, allowing for maximum flavor extraction while completely blocking fine sediment. Paired with an ergonomic "V-shaped" spout, we ensure a drip-free pouring experience, providing strong product support for your brand’s premium positioning.

Guan International is more than just a manufacturer; we are your dedicated quality control center. Every batch undergoes rigorous inspection for glass stress annealing, lid seal integrity, and material compliance audits. We provide the full certification support you need to shield your brand reputation and build long-term trust in a competitive global market.
