BEIJING - China's Ministry of Commerce (MOC) said Tuesday it has found that the European Union (EU) and Japan have been dumping certain high-performance stainless steel seamless tubes into the Chinese market.

Investigations showed the dumping has "substantially harmed" Chinese producers, and importers of those products will have to pay anti-dumping deposits to China's customs authorities starting from Wednesday, the MOC said in a preliminary ruling released on its website.

The deposits will be charged in accordance with the dumping margins of different producers, at rates ranging from 9.7 percent to 39.2 percent of the customs value of the imported goods, according to the ruling.

Interested parties can submit their comments and evidence to the ministry within 20 days after the release of the ruling, the MOC said.

China launched anti-dumping probes into certain high-performance stainless steel seamless tubes made in the EU and Japan in September last year.
