Q

What is your Minimum Order Quantity (MOQ) and typical production lead time?

For standard items in regular production, we offer flexible, low MOQ options to support both growing brands and large-scale enterprises.

How are the products packaged, and how is the shipping cost calculated?

We typically use cardboard boxes for packaging, but direct container loading is also an option.

CIF includes product cost, insurance, and freight, while FOB covers product cost and shipping charges. The specific packaging and shipping cost will be adjusted based on your order and location.
