VI. TRADE REGULATIONS AND STANDARDS The Latvian customs tariff system is still evolving. Under an interim tariff system introduced in March 1994, Latvian customs tariffs on manufactured products are generally low, with higher tariffs on agricultural products reflecting the desire of Latvian farmers for protection. While a tariff bill was defeated in the Saeima (Parliament) in July 1994, political pressure for protectionist tariffs from farmers can be expected to remain high. Latvia currently has no quantitative constraints on food imports. Latvia extends MFN treatment to U.S. Products. Latvian tariff classifications are based on the harmonized commodity description and coding system (HCDC). In addition to tariffs, imports are subject to excise taxes and the 18 percent turnover tax. The turnover tax may be waived for the import of fixed investment goods upon application to the Latvian development agency. Excise taxes are applied to alcoholic beverages, tobacco and jewelry. Import documentation required by Latvian customs authorities are a copy of the contract, an invoice, a bill of lading indicating the amount, weight and value of goods, and an original copy of a certificate of origin (form Eur.1 or Form a). At the border, an importer or his agent must complete a customs declaration and a customs freight delivery note. For meat imports, the state veterinary department provides border inspection controls for bovine spongiform encephalopathy, classical swine fever, and salmonella. Effective June 1, 1994, imported food products were required to have conformity certificates to guarantee quality and wholesomeness of food products. Latvia is still formulating food safety standards. Transit freight (mainly to and from Russia) can either be organized in special customs convoys if they involve the shipment of non-ferrous metal or metal scrap or hazardous cargoes such as chemical, explosives, ammunition, or drugs. The convoy fee is 100 lats per truck or per truck with trailer. Shipments of alcohol, tobacco, food products and perfume are also convoyed, for which the convoy fee is 50 lats. A high security deposit may be paid at the border in lieu of using a convoy. The security deposit is transferred to the customer's bank account two months after the shipment has left Latvian territory. Some Latvian exports (mainly raw materials, metals, antiques and art works) are subject to an export tax. Latvia is pursuing foreign-trade policies consistent with market reforms and the need to diversify the country's trade partners beyond the former Soviet Union. Latvia has free-trade agreements with Sweden, Finland, Norway and Switzerland. On January 1, 1995, a free-trade agreement with the European Union will begin a phased implementation. In April 1994, a trilateral free-trade agreement between the three Baltic countries was implemented, abolishing all tariffs on industrial products. A separate protocol on agricultural, forestry, and fishery products is still being negotiated. Latvia's application for GATT membership is currently undergoing review.
