Duty liability
(Anti-dumping & Countervailing duties)

Country of origin or export: China

Effective on imports of subject goods released by the CBSA on or after 2011-02-14:

No exporters in China received normal values or a specific amount of subsidy in the most recent re-investigation, please consult CBSA Notice of Conclusion of Re-investigation.

The liability for anti-dumping and countervailing duty results from the proceedings conducted under SIMA and from the CITT order. Given that no exporters or producers provided a response to the CBSA’s RFI, normal values and amount of subsidy will therefore be determined by a ministerial specification under SIMA.

For importations of subject goods originating in/or exported from China, the anti-dumping duty is equal to 179% of the export price, as specified by the Minister.

For importations of subject goods originating in/or exported from China, the countervailing duty is equal to 5,280 Renminbi per metric tonne, as specified by the Minister.

For information on duty assessment, refer to the Guide for self-assessing SIMA duties.
