Dishwasher rack

The most critical factor is the coating and base metal. You should prioritize 304 or 316 Stainless Steel for high-end durability, or Low-Carbon Steel wire with a thick Nylon (Rilsan) or PVC coating. Nylon coating is superior as it offers better heat resistance (up to 150°C), chemical stability, and prevents the wire from rusting, which can damage the dishwasher pump.

Dishwasher racks are not universal. You must verify the exact dimensions (Width x Depth x Height) and the wheel/roller assembly spacing. For B2B sourcing, request CAD drawings or 3D models from the supplier to confirm the tine layout (fixed vs. foldable) and ensure the rack accommodates specific dishware sizes common in your target market.

Since the rack comes into contact with foodware, it must meet FDA (USA) or LFGB (Germany/EU) food-grade contact standards. Additionally, ensure the coating material is BPA-free and complies with RoHS to guarantee no heavy metals or toxic chemicals leach out during high-temperature wash cycles.

Demand a Salt Spray Test report (minimum 500-1000 hours) to verify corrosion resistance. You should also ask for Adhesion Testing (Cross-cut test) for the coating to ensure it won't peel, and a Load-Bearing Capacity test to confirm the rack can hold a full load of ceramic plates (typically 15-25kg) without sagging or structural failure.

Implement a Pre-Shipment Inspection (PSI) focusing on coating integrity. Even a pin-sized hole in the nylon coating will lead to rapid oxidation during transit in humid sea containers. Ensure the supplier uses VCI (Volatile Corrosion Inhibitor) packaging or moisture-absorbent silica gel packs within the master cartons.

Focus on Tooling Costs and Volume Rebates. If you require a custom design, negotiate the Mold Fee; many suppliers on Made-in-China.com will refund the tooling cost once a certain order volume (e.g., 5,000 units) is reached. Always clarify the Incoterms (FOB is recommended) to maintain control over your freight costs.

Use Secured Trading Services provided by reputable platforms like Made-in-China.com to ensure your payment is held in escrow until shipping documents are verified. Avoid 100% upfront payments; a standard 30% deposit / 70% balance against Bill of Lading (B/L) is the industry norm for established B2B relationships.

Dishwasher racks are 'light cargo' (high volume, low weight). To optimize shipping costs, request stackable designs or knock-down (KD) versions if the tines are removable. Calculate the CBM (Cubic Meter) carefully, as shipping costs may be calculated based on volumetric weight rather than actual weight.
