Stainless colander

For B2B sourcing, prioritize 304-grade stainless steel (18/8) as it offers superior corrosion resistance and food safety. While 201-grade is more economical, it is prone to rusting in high-moisture environments. Ensure the supplier provides a Material Test Report (MTR) to verify the nickel and chromium content.

Focus on the perforation pattern; micro-perforated holes (approx. 1.5mm to 2mm) prevent small grains like quinoa from escaping while allowing rapid drainage. The base design is also critical—look for a solid pedestal base or welded feet rather than a simple ring to ensure stability and hygiene by preventing water trapped underneath.

Products must be BPA-free and comply with FDA (US) or LFGB (Germany/EU) food contact regulations. For the European market, ensure the product meets Regulation (EC) No 1935/2004. Always request Migration Testing reports from accredited third-party labs like SGS or TUV.

The most common failure point is the handle attachment. Specify riveted handles for heavy-duty commercial use, as they are more durable than spot-welded ones. If choosing welded handles, ensure they are argon-arc welded with a smooth finish to prevent bacterial buildup and ensure a load-bearing capacity of at least 10kg.

Implement a Pre-Shipment Inspection (PSI) and specifically request a Salt Spray Test (usually 24-48 hours) to verify rust resistance. Use Made-in-China.com's Secured Trading services to ensure payment is only released after the quality inspection report is approved.

Negotiate based on raw material price indexes. Since stainless steel prices fluctuate, ask for a price validity period (e.g., 15-30 days). For bulk orders exceeding 5,000 units, aim for a 5-8% volume discount or request customized laser-etched branding included in the unit price.

Colanders are bulky and prone to denting. Require nested packaging with PE foam inserts between each unit to prevent scratching. Ensure the outer cartons are 5-layer corrugated fiberboard with a bursting strength suitable for sea freight to avoid deformation during stacking.

Verify the HS Code (typically 7323.93) to determine import duties in your country. For large volumes, FOB (Free On Board) terms are recommended to maintain control over shipping costs. If sourcing from Made-in-China.com, look for Audited Suppliers who have experience with consolidated shipping (LCL) to reduce landed costs.
