China will impose five-year anti-dumping tariffs, ranging from 5 percent to 35.4 percent, on imports of adipic acid from the United States, the European Union and the Republic of Korea, the Ministry of Commerce (MOC) said on Sunday.

The tariffs will take effect on Monday this week, the ministry said.

The ministry said its investigation department had ruled that the three economies had dumped adipic acid on the Chinese market and had caused substantial damage to the domestic industry.

The ministry started an anti-dumping investigation into adipic acid imports last November.

In June this year, the ministry started to levy a security deposit, as a temporary anti-dumping measure, on adipic acid imported from the three countries.

Adipic acid is primarily used in the production of nylon 6-6 and for manufacturing polyurethane foam and polyester resins.
