Glass jug set factory

You should prioritize High Borosilicate Glass (3.3 expansion coefficient) if the jugs are intended for both hot and cold beverages, as it withstands thermal shock up to 150°C. For everyday cold beverage use, Soda-Lime Glass is more cost-effective but less resistant to temperature fluctuations. Ensure the glass is Lead-free and Cadmium-free to meet food safety standards.

For the US market, products must comply with FDA 21 CFR regulations regarding food contact surfaces. For the EU, LFGB (Lebensmittel- und Futtermittelgesetzbuch) and Regulation (EC) No 1935/2004 are essential. Always request Declaration of Compliance (DoC) and recent lab test reports from the factory to avoid customs seizures.

Focus on the annealing process; poorly annealed glass has internal stresses that lead to spontaneous breakage. Check for bubbles, stones, or mold marks which indicate low-quality control. For sets with lids, verify that 304 Stainless Steel or Food-grade Silicone is used for the seals to prevent leakage and rust.

Professional factories on Made-in-China.com usually offer decal printing, sandblasting, and color glazing. For high-end brands, you can request custom mold development for unique shapes. Ensure the factory provides 3D renderings or CNC samples before mass production to verify the design.

Glassware requires 5-layer corrugated outer cartons and individual EPE foam or bubble wrap packaging. Request a Drop Test Report (ISTA 1A or 2A) from the supplier. For bulk sea freight, ensure the use of pallets with plastic wrap to minimize manual handling shocks.

Negotiate based on Volume Tiers; glass production is energy-intensive, so larger runs significantly lower the unit cost. Discuss breakage allowance—standard agreements often include a 2-3% defect/breakage credit on future orders. Always clarify Incoterms (FOB vs CIF) early to avoid hidden logistics surcharges.

Utilize the Secured Trading Service on Made-in-China.com to protect your payments. Never transfer full payments upfront; a standard 30% deposit and 70% balance against the Bill of Lading (B/L) is the industry norm. Conduct a Pre-Shipment Inspection (PSI) via a third party like SGS or Intertek to verify quality before final payment.

When shipping to the US or EU, be aware of Anti-Dumping Duties that may apply to certain types of glassware. Work with a freight forwarder experienced in Fragile Cargo to ensure proper 'Top Load Only' labeling and container stuffing to prevent crushing.
