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

Information Required on Customs Documents

The import documentation should include the information listed below. Failure to provide this information may result in the application of penalties to the importer, pursuant to the Administrative Monetary Penalty System (AMPS).

The import documentation should clearly indicate the following:

  • Country of origin
  • 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:

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

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 on the CBSA's Web site at: https://decisions.citt-tcce.gc.ca/citt-tcce/a/en/item/354636/index.do). 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". 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 found in https://decisions.citt-tcce.gc.ca/citt-tcce/a/en/item/354636/index.do, 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.
