The US government has set a 23 August deadline to reach a preliminary injury determination in anti-dumping and countervailing duty (CVD) probes into imports of utility-scale wind towers from Canada, Indonesia, South Korea and Vietnam.

The International Trade Commission (ITC), a quasi-judicial federal agency of the US government, launched the investigations in response to petitions filed 9 July by the Wind Tower Trade Coalition (WTTC), an association of domestic manufacturers.
