According to new Customs dispositions in Bolivia : all bill's of lading should mention the cargo packing details. For example:
1 Pallet: with 25 carton boxes stc: 80 books 1 Pallet: with 2 boxes stc: personal effects
No more will they accept specifications as just: One pallet, One bundle, etc. If cargo will arrive without the packing specifications there will be Bolivian customs fines, which will be invoiced to origin office.
