AWhy you should not do customs clearance of your own?
Given the constant changes in legislation, strict requirements for paperwork, and a rather complicated chain of the process itself, customs clearance on its own is quite difficult. A hindrance to the quick implementation of clearance can be:
Lack of proper experience and knowledge
Human factor (illness, fear, etc.)
As a rule, proper customs clearance takes about 24 hours, after which the cargo is completely ready for sale or use. In case of independent customs clearance, the final date of shipment is quite difficult to predict.
