Glass tea cup set

Professional buyers should prioritize High Borosilicate Glass (GG-17). This material is superior to soda-lime glass because it has a low coefficient of thermal expansion, allowing it to withstand extreme temperature shocks from -20°C to 150°C without cracking. Ensure the glass is lead-free and cadmium-free to meet food-grade safety requirements.

Look for sets featuring removable 304 stainless steel or glass infusers with fine mesh to ensure clear tea liquor. For double-walled designs, verify the presence of a silicone vent hole at the bottom, which manages air pressure between the glass layers. Ergonomic handle design and non-drip spouts are critical for user experience in hospitality and retail environments.

To ensure smooth customs clearance and consumer safety, products must comply with FDA (USA) or LFGB (Germany/EU) food contact regulations. For the European market, CE marking and REACH compliance are often requested. Always ask the supplier for SGS or TUV laboratory test reports specifically for heavy metal leaching.

Inspect for optical clarity; high-quality glass should be free of bubbles, scratches, or a greenish tint. Check the annealing process quality—poorly annealed glass has internal stress that leads to spontaneous breakage. The rims should be smooth and fire-polished, and the weight should feel balanced, neither too fragile nor excessively heavy.

Glass is a high-risk category for damage. Insist on 5-layer corrugated export cartons and individual bubble wrap or EPE foam packaging for each component. For bulk orders, palletization with shrink wrap is mandatory to prevent rough handling. You should negotiate a breakage allowance (typically 2-3%) or a replacement clause in your contract.

Focus on MOQ (Minimum Order Quantity) flexibility for customized logos or packaging. While a standard MOQ might be 1,000 sets, you can negotiate a lower trial order by paying a slightly higher unit price. Use Made-in-China.com's 'Diamond Member' or 'Audited Supplier' status as a filter to find reliable factories with proven export histories.

Always use secure payment methods such as Letters of Credit (L/C) for large volumes or Escrow-based services provided by reputable B2B platforms. Avoid direct wire transfers to private bank accounts. Conduct a pre-shipment inspection (PSI) through third-party agencies like V-Trust or QIMA to verify quality before the final balance is paid.

Due to the high volume-to-weight ratio, Sea Freight (FCL or LCL) is the most economical for bulk orders. For high-value or urgent samples, Air Express (DHL/FedEx) is suitable but expensive. Ensure the Incoterms are clearly defined; FOB (Free On Board) is generally preferred for buyers who want control over their logistics and shipping costs.
