The government has announced it will impose anti-dumping tariffs on imports of a chemical additive used in livestock feed and medicine from the U.S., China, India and Canada.

The Korean Trade Commission says it will soon recommend immediate anti-dumping action to the Finance Ministry.

The commission's final ruling is based on its 10-month investigation following complaints by local manufacturers in December last year that choline chloride imports damage the industry since they are imported at below-market prices.

Earlier in May, Seoul imposed preliminary anti-dumping duties after it concluded that choline chloride imports from the countries had unfairly undercut prices.
