Uruguayan Customs place a cap on the importation of personal packages to up to 3 packages of a nominal value of no more than US$200 which can be entered into the country without extra charge. For a package to be included in the 3 free slots, the addressee must register the package with the Uruguayan Postal Service linking the tracking code, their address, national ID number phone and email address. Should a package arrive prior to registration the package must pay the 60% tax and no less than US$10. Any personal package worth more than US$200 or after the 3 free packages, must pay a 60% tax. This severely limits the public's ability to buy products online. Due to Uruguay's small population and market, many popular and specialty products are unavailable in the regular marketplace, forcing Uruguayans to strategically pool several purchases together and max each one of their free slots.
