Disclosure of normal values and amounts of subsidy

The liability for anti-dumping and countervailing duty results from the proceedings conducted under SIMA and from the finding of the CITT. Information regarding the normal value and amount of subsidy of the subject goods in question and the amount of anti-dumping and countervailing duty payable should be obtained from the exporter. Related information may be made available to importers on a need-to-know basis in accordance with the provisions of Memorandum D14-1-2: Disclosure of Normal Values, Export Prices, and Amounts of Subsidy Established Under the Special Import Measures Act.

General information for CBSA assessment and revenue management (CARM)

CARM is the official system of record for the assessment and collection of duties and taxes on imported commercial goods. In most circumstances, the CARM system will automatically calculate the amount of SIMA duties payable based on information provided; however, it is still your responsibility to verify that the amounts assessed are correct and, if necessary, self-declare correct amounts. For additional information relating to CARM and self-assessing SIMA duties, please refer to the Guide for self-assessing Special Import Measures Act duties and applicable D-Memorandums.

Requests for re-determination information for CARM

Requests for re-determination relating to SIMA duties must be filed by the importer or the importer's agent via the CARM Client Portal (CCP), through the Statements of adjustment and appeals. Failure to submit correctly may result in rejection and/or delayed processing.

Summary decisions made by the CBSA respecting whether an imported good is subject to this measure in force can be found on President-level re-determinations.

Information required on customs documents

Listed below is the information that must be provided to the Canada Border Services Agency regardless of whether the documentation is provided as paper or electronically (e.g. through the use of ACROSS). Please note that if the following information is not provided, then the normal value will be determined based on the export price advanced by 170% and the amount of subsidy for goods originating in or exported from the People's Republic of China will be equal to 1.25 Renminbi/kilogram. Failure to provide this information may also result in the application of penalties to the importer, pursuant to the Administrative Monetary Penalty System (AMPS). The Customs Act applies, with any modifications that the circumstances require, with respect to the accounting and payment of anti-dumping or countervailing duties.
