You can freely match and ship the goods "in the warehouse" in my order, and choose to send them all at once or in batches.
Reminder: The important basis for the customs of various countries to judge civilian and commercial packages is the weight of the package and the quantity of items. It is more likely to be regarded as a commercial package if it exceeds 10KG, so when submitting the waybill, please confirm the weight of the package. Excessive quantities of the same item are also regarded as one of the important basis for commercial parcels, so please try to avoid using the same package to send a large number of single products.
