Supporting Customers in 

North America

We support B2B buyers across the United States and Canada with product selection, quotations and coordination with our manufacturing team in China. Folding crates are a core focus of our reusable packaging range.

Our North American sales support helps buyers discuss dimensions, applications, quantities and customization. Manufacturing and export coordination take place in China. We do not currently operate a North American warehouse; delivery arrangements are agreed for each order.

Our standard minimum order is 500 units. Samples are free, with freight agreed case by case, and generally dispatch in about 3 business days. Confirm availability and any custom sample timing with our team. Production lead time and shipping arrangements are agreed during quotation.

Explore folding crates or custom packaging options, then send your requirements for a quotation.
