These charges are separate from your shipping charge, and you will be billed directly for them by your local customs office. Please contact your local Customs office for more details.
There are two different types of customs clearance for imported parcels:

The recipient pays the customs fees, VAT and handling costs upon delivery. Swiss Post collects the money upon delivery (COD), while private forwarders such as General Parcel Switzerland send the invoice afterwards.
