Large items often require dispatch via Less-Than-Truckload (LTL) or specialized freight services, and they may be split into multiple separate packages when necessary. 

This practice is essential due to:

1) International Transportation Policies: 

Strict limitations imposed by international shipping regulations on the maximum volume, size, and weight permitted for a single parcel.

2) Customs Clearance: 

Large shipments typically undergo more thorough inspection and processing at customs, which may necessitate specific handling requirements that favor divided shipments.
