Wholesale supermarket trolley bag manufacturers

When sourcing for wholesale, prioritize 600D or 900D Oxford cloth with a PVC or PU coating for water resistance and tear strength. For eco-conscious markets, look for RPET (Recycled Polyethylene Terephthalate) materials. Ensure the fabric weight is sufficient to handle loads of at least 15-20kg without seam failure.

The frame should be constructed from lightweight aluminum alloy or powder-coated steel to prevent rust. For wheels, EVA foam wheels offer a silent ride, while tri-wheels (stair-climber design) are highly sought after for urban consumers. Ensure the axle is made of solid steel rather than plastic to prevent snapping under heavy loads.

Suppliers should provide REACH or RoHS certification to ensure the plastics and dyes are free from harmful chemicals like phthalates. If exporting to the US, ensure compliance with California Proposition 65. For load-bearing claims, request GS (Geprüfte Sicherheit) certification or internal load-test reports.

Look for value-added features such as insulated thermal linings for frozen foods, foldable frames for easy storage, and ergonomic handles with soft-grip padding. High-quality bags should also feature reinforced baseboards and secure attachment points to the frame to prevent sagging.

Always request a pre-production sample (PPS) and conduct a third-party during-production (DUPRO) inspection. Focus specifically on the stitching density (at least 6-8 stitches per inch) and the smoothness of the folding mechanism. Using Made-in-China.com's Secured Trading Service can provide an extra layer of payment protection until the goods pass inspection.

Negotiate based on Total Cost of Ownership (TCO) rather than just unit price. Ask for tiered pricing (e.g., 500, 1000, and 5000 units) and inquire if the supplier can provide customized logo printing (OEM) included in the bulk price. For long-term partnerships, negotiate a 2-5% spare parts allowance for wheels and plastic clips.

Trolley bags are 'volumetric' cargo. To reduce shipping costs, request knocked-down (KD) packaging, where the bags and frames are packed separately or nested to maximize container utilization. Ensure the outer cartons are 5-layer corrugated fiberboard to prevent crushing during sea freight.

Verify the supplier's Business License and Export Qualification on Made-in-China.com. Use Incoterms 2020 clearly in your contract (e.g., FOB or CIF) to define where risk transfers. Be aware of Anti-Dumping duties that some regions may apply to specific textile or steel products originating from overseas.
