Machine Tool Industry Import and Export Policy in 2010

On August 20, 2009, the Ministry of Finance, the Development and Reform Commission, the Ministry of Industry and Information Technology, and the General Administration of Customs jointly issued the "Notice on Adjustment of the Import Tariff Policy for Major Technical Equipment" (hereinafter referred to as the "Notice").

The "Notice" pointed out that starting from July 1, 2009, key imported spare parts and raw materials that are necessary for domestic enterprises to produce major technical equipment and products that support the development of the country are exempted from import duties and import value-added tax ( The import tax policy released on March 26, 2008 was implemented for the first time, and the tax refund was treated as a national investment and transferred to the state capital, which was mainly used for the development and production of new products for enterprises and the capacity for independent innovation. These include 12 large-scale, precision, high-speed CNC machine tools, numerical control devices and 6 key functional components.

The "Notice" stipulates that the import tax exemption policy for complete machines and complete sets of equipment shall be abolished. The "Notice" also stipulates that manufacturing companies that enjoy the preferential tax policies of this regulation must undergo qualification certification. From March 1 to March 31 each year, they submit their application documents to the Ministry of Industry and Information Technology through their local provincial industrial and information management department, and copy the application documents. Send the local Customs and Finance Department to the local financial Ombudsman office. After verification, the Ministry of Industry and Information Technology shall notify the Ministry of Finance of the company’s qualification confirmation and related factor verification results by May 10 of each year. The Ministry of Finance, together with the General Administration of Customs and the State Administration of Taxation, clearly specify the list of enterprises enjoying annual preferential policies and the list of duty-free import quotas.
