- For Canadian international merchandise trade by industry, the concordance between the HS and NAICS codes is a mapping of import HS10 codes and export HS8 codes to six-digit NAICS 2017 V. 2 structure codes using the industry of origin (or supply side), with a few codes HS codes grouped into 5-digit NAICS codes, for both imports and exports. Although straightforward for exports, the industry of origin approach for imports means that import data are compared to the Canadian industries that would be the primary producers and competitors of these imported goods.
- The TEC linkage uses the industry of origin and the industry of exporter concept. For example, a producer in the oil and gas extraction industry would be the appropriate company to extract and export oil. If the original producer cannot be found, the linkage is made to the business who files export declaration forms to Canada’s Border and Services Agency (CBSA), most likely a wholesaler. TIC linkage uses the industry of ultimate user and the industry of importer concept.
- For value added in exports by industry, the exports measurement is based on domestic producing industry and inter-industry purchases. Imports are measured based on the foreign producing industry (industry of origin) as well as the industry of use.
