BEIJING - China will levy anti-dumping duties on imports of iron based amorphous alloy ribbon from the United States and Japan by requiring deposits for such imports, the Ministry of Commerce said on Thursday.

The move came after the initial findings of an investigation launched late last year showed evidence of dumping, according to the ministry's website.

Importers will be required to pay customs deposit fees ranging from 25.9 percent to 48.5 percent according to the level of dumping.

The ministry did not specify when the measure will take effect.

In November, when China announced its investigation into the sales of iron based amorphous alloy ribbon from US and Japan, it said the probe was likely to end before Nov 18, 2016, but could be extended to May 18, 2017.
