"Article 48. For the purposes of Article 33 of the Act, centrally planned economies, regardless of the name by which they are designated, shall be deemed, subject to contrary evidence, to be those whose cost and price structures do not reflect market principles, or in which the enterprises of the sector or industry under investigation have cost and price structures which are not determined in accordance with such principles, and hence, in both cases, sales of the identical or like product in the country in question do not reflect the market value or the value of the factors of production used in manufacturing an identical or like product in a third country with a market economy. In order to determine whether an economy is a market economy, the following criteria, inter alia, shall be taken into account: the currency of the foreign country under investigation must be generally convertible in the international currency markets; salaries in the said foreign country must be established through free negotiation between workers and employers; decisions relating to prices, cost and supply of inputs, including raw materials, technology, production, sales and investment, in the sector or industry under investigation, must be taken in response to market signals without any significant State interference; the industry under investigation must have only one set of accounting records which it uses for all purposes and which is audited according to generally accepted accounting criteria; and the production costs and financial situation of the sector or industry under investigation must not be distorted in relation to the depreciation of assets, bad debts, barter trade and debt compensation or other factors considered relevant.
