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 Canadian International Trade Tribunal (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 to Importers.

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

The import documentation should clearly indicate the following:

  • Confirmation whether the product is subject to anti-dumping duty and/or countervailing duties
  • Exporter ID
  • Country of origin
  • Country of export
  • Name and address of producer/manufacturer, if known (mandatory where the vendor is not considered the exporter for SIMA purposes)
  • Location of plant/mill of production, if known
  • Place from which direct shipment to Canada began
  • Name and address of vendor (if different from producer)
  • Customer's name and address
  • Canadian importer's name and address (if different from the customer)
  • Full product description including:
    • Model ID
    • Model description
    • Type of fitting: Indicate model name in terms of one of the following:
      • Female Adapter, Male Adapter or Other Adapter
      • Bushing
      • Coupling
      • Elbow
      • Flange
      • Pressure Tee
      • Union
      • P Trap
      • DWV TY
      • DWV Y
      • Cap and Cleanout
    • Additional information for product type: Where applicable, provide additional product description for each product. For example, identify female adapters that are female street, female drop ear and female hi ear.
    • Configuration or Connection of the Fitting: Indicate each configuration or connection (e.g., C, M, FE, FTG identified in the Abbreviation Chart for copper pipe fittings). For example, a female street adapter has a connection consisting of FTG X FE.
    • Size of the fitting: Indicate the nominal size(s) of the fitting. The nominal size of each connection is to be shown in "inches".
    • Additional information for the size of the fitting: Plumbing and heating fittings are marked according to nominal sizes that correspond to the inside diameters, while fittings for air conditioning and refrigeration are based on the actual outer diameter sizes. To determine the nominal size of a fitting that is measured in terms of its outside diameter size, always subtract 1/8" from the outside diameter size. If the size of the fitting is identified in "metric" but not made specifically to metric dimensions, indicate the equivalent measurement in inches.
    • Application of the fitting:
      • Indicate "WO" for Wrought Pressure
      • Indicate "WD" for Wrought Drainage
      • Indicate "CP" for Cast Pressure
      • Indicate "CD" for Cast Drainage
      • Indicate "PH" if this product was sold for a plumbing and heating application
      • Indicate "ACR" if this product was sold for an air-conditioning and refrigeration application
      • Indicate "ALL" if you are not aware of the application
    • Match to the list of fittings identified in the Tribunal's finding: Using the list of copper pipe fittings, indicate the description which is identical to the product that was shipped to Canada. Please note that a cast (wrought) model shown with an asterisk is a match for a wrought (cast) model you shipped to Canada if it has all of the other model characteristics, i.e. configuration and size.
  • Date of sale, date of shipment
  • Quantity (including the unit of measure)
  • Unit selling price, total selling price
