5pcs glass bowl set manufacturers

When sourcing glass bowl sets, the primary material choice is between Soda-Lime Glass and Borosilicate Glass. Soda-lime is cost-effective for general food storage, while High-Borosilicate Glass is essential if the product needs to be microwave, oven, and dishwasher safe due to its superior thermal shock resistance. Ensure the glass is lead-free and cadmium-free to meet food safety standards.

The lids are typically made of PP (Polypropylene) or PE (Polyethylene). For airtight requirements, look for lids with silicone sealing rings and four-sided locking mechanisms. Ensure the lids are BPA-free. If the set is intended for nesting, the lids must be designed to stack securely without cracking under pressure.

For the US market, products must pass FDA (Food and Drug Administration) testing. For the EU, compliance with LFGB (Lebensmittel- und Futtermittelgesetzbuch) and EC 1935/2004 is required. These certifications verify that no harmful substances migrate from the glass or lids into food. Always request third-party lab reports (SGS, TUV, or Intertek) from the supplier.

A standard 5pcs set usually follows a nested design to save shipping space. Typical capacities range from 150ml, 250ml, 450ml, 600ml, to 1000ml. Verify the wall thickness (ideally 2mm to 3mm) to ensure durability during transit and daily use.

Glassware is high-risk for damage. You must mandate 5-layer corrugated export cartons and individual bubble wrap or EPE foam for each set. Request a Drop Test Report (ISTA 1A or 2A). For bulk sea freight, ensure the use of pallets with plastic wrap to prevent shifting and moisture ingress.

Focus on Tiered Pricing based on volume; for 5pcs sets, a 2000-set order can often reduce the unit price by 10-15% compared to the MOQ. Negotiate for customized color box packaging included in the price for orders exceeding 3000 units. Always clarify the Incoterms (FOB is recommended) to maintain control over freight costs.

Utilize Secured Trading Services on Made-in-China.com to protect your payment until delivery. Before the final payment, hire a third-party inspection agency to perform a Random Sampling Inspection (AQL 2.5/4.0) to check for bubbles, scratches, or ill-fitting lids. Never skip the pre-shipment sample approval phase.

Glass is heavy and relatively low-value, making Sea Freight (LCL or FCL) the only economically feasible option for bulk orders. Calculate the CBM (Cubic Meter) carefully; because these sets are nestable, they offer excellent space efficiency, which can significantly lower your landed cost per unit.
