Just to clarify:

Buyers pay import charges (including tax and customs fees) when purchasing items from another country. Import charges are generally based on the item's price, shipping weight, dimensions, country of origin, and taxes, duties, and fees of the destination country.

Applicable listings show an estimated import charge because the seller is in ebay's Global Shipping Program, which lets buyers pay the import charge up front and receive items faster. The import charge in a listing is only an estimate that's based on the current or maximum bid, current Best Offer or counteroffer, or Buy It Now price. The actual import charges you'll pay will be shown at checkout
