The government of Uzbekistan restricts foreign imports in many ways, including high import duties. Excise taxes are applied in a highly discriminatory manner to protect locally produced goods, although the excises taxes were removed in for foreign cars in 2020. Official tariffs are combined with unofficial, discriminatory charges resulting in total charges amounting to as much as 100 to 150% of the actual value of the product, making imported products virtually unaffordable. Import substitution is an officially declared policy and the government proudly reports a reduction by a factor of two in the volume of consumer goods imported. A number of CIS countries are officially exempt from Uzbekistan import duties. Uzbekistan has a Bilateral Investment Treaty with fifty other countries.
