The US is conducting an antidumping (AD) and countervailing duty (CVD) probe into imports of steel nails from seven countries, including Vietnam.

According to the Vietnam Competition Authority(VCA), the US firm is accusing the imports of having a dumping margin of 323.99% and an estimated subsidy that surpasses the minimum level.

As scheduled, the US International Trade Commission (ITC) will issue its preliminary determination of material injury or threat of material injury within 45 days, or no later than July 14, 2014.

The DOC will then announce preliminary countervailing duties in 85 days and preliminary antidumping duties in 160 days, though both deadlines may be extended.

This is the fourth AD and CVD lawsuit the US has filed against Vietnamese products since 2011, following similar suits involving P.E plastic bags, carbon welded steel pipes and steel wire garment hangers.

US Customs statistics show that last year Vietnam earned about US$43.7 million from exporting 39,000 tonnes of steel nails to the US, accounting for approximately 17% of the US market share.
