Packages sent internationally may incur import duties, custom fees, and/or handling charges by the destination country. These charges are typically due once the package arrives in that country.
Generally, the buyer is responsible for paying these additional fees. These charges can vary widely and are often based on the price and type of item, package weight and dimensions, origin country, and the duty laws of the destination country.
Your seller will not be able to tell you in advance how much you may need to pay in additional fees. Neither the seller nor Depop are responsible for these fees.
To be sure of avoiding these fees, shop locally and check that your seller is based in your own country before purchasing.
