We're responding to your RFQ with confidence on teh KM-SHC series — basically every batch ships with a COA from HPLC analysis and a full inspection report.

The 60L to 240L options (you'll likely go with 150L or 180L for standerd retail) pass our 1,000-hour salt spray test on the zinc coating and powder finish, so corrosion resistnce is solid even in high-moisture environments.

PVC and PU bearing wheels both wear tested at 500km of simulated floor traffic, and we'll retest any lot that shows more than 3% deviation form baseline — just send us a sample if you're concerned.
And our company can lock in a set MOQ of 200 units on any single color and plastic part spec, lead time typically runs 20 business days or so from PO — (custom logo on handlebar is included).

Actually, the herringbone design and single handle are fine for self-service aisles, but it's not suited for tight warehose picking where a folding cart would be better.

Purity on the steel alloy is verified via in-house XRF every 50 units, and we've got a batch consistency report from our last three if you want to compare tolerances before placing the order.
The MOQ varies by model and customization. For standard colors and sizes, we usually start at 50 units per model. Custom colors or plastic parts may require a higher MOQ, so just let us know what you need.
For a bulk order of 1000 units, expect around 20 to 30 working days after we confirm the order and specifications. This includes production and packing. If you need custom colors or locks, it might add a few extra days.
Yes, we can supply a material certificate for the steel and zinc coating upon request. It’s standard for our export orders, so just mention it when you place the order.
They’re physically different—the 60L is a smaller cart, while the 240L is larger with a bigger basket. The Herringbone design is consistent across all models, but dimensions change with capacity. We can send exact specs if needed.
Each trolley comes in a bubble bag for surface protection, and we pack them in sturdy cartons or on pallets depending on the order size. For large bulk orders, we usually palletize them to prevent shifting during transit.
