Canadian international merchandise trade by industry for all countries
Detailed information for September 2023
Canadian international merchandise trade by industry for all countries provides Canada's merchandise imports and exports by industry and partner country on a customs basis. The data published is based on the concordance of Harmonised System (HS) codes to the North American Industry Classification System (NAICS) codes of the NAICS 2017 v. 2.0 structure.
Data release - November 7, 2023
Statistics Canada has updated the concordance between Harmonised System (HS) codes and North American Industry Classification System (NAICS) codes to the most recent industry classification, i.e., NAICS 2017 v. 2.0. Canadian international merchandise trade by industry for all countries provides Canada's merchandise imports and exports by industry and partner country on a customs basis according to that concordance.
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 few codes HS codes grouped into 5-digit NAICS codes. 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. Hence, with few exceptions, manufactured goods are mapped to the manufacturing industries which primarily produce these goods, and agricultural or other primary goods are assigned to agricultural, mining or other primary industries which primarily produce those goods.
For imports, each good is deemed to be the principal product of a single industry as the Customs Tariff is deemed to have enough detail, at respectively 19,189 codes in 2002 and 10,771 in 2017, to warrant assignment of all classes to only one NAICS, rather than assigning weights, without losing a great deal of industry of origin detail.
For exports, there are distribution factors meaning that the weight of one HS code may be distributed to more than one NAICS code. In general, most goods have a one to one correspondence. For example, only 5.9% of unique export HS8 codes have distribution factors in 2017.
For imports, other options of mapping HS codes to NAICS codes such as industries that only import the goods or industries that wholesale or retail the goods are not retained as they are not consistent with the production-oriented principles of NAICS.
For exports, other options of mapping HS codes to NAICS codes such as industries that only export the goods or industries that wholesale the goods are not retained as they are not consistent with the production-oriented principles of NAICS. They can lead to situations where head offices and brokers are exporters.

Data sources and methodology
Canadian merchandise import and export data are recompiled according to the industry of origin. The term "industry" refers to a group of businesses that produce the same or similar products. These groups are defined by the NAICS codes. For example, the industry group 3361 comprises establishments primarily engaged in manufacturing motor vehicles. Establishments that manufacture chassis and then assemble complete motor vehicles (including truck cab and chassis assemblies) and those that only manufacture motor vehicle chassis are both classified in this industry group.
This methodology does not apply.
The administrative data are collected for all units of the target population, therefore no sampling is done.
Data are extracted from administrative files.
Import data are collected via electronic transmission of Canada's Border Service Agency (CBSA) B3 forms to Statistics Canada on a weekly basis. When goods are imported into Canada, B3 forms must be submitted to the Canada's Border Services Agency (CBSA) and include the description and value of the merchandise, the country of origin, port of clearance, the mode of transport used, etc. The country of origin is the country where the goods are mined, grown, or manufactured or where the final stage of transformation takes place.
Data for exports to the United States are collected via electronic transmission of the United States Census Bureau data according to a 1987 Memorandum of understanding between Canada and the Unites States. Since 1990, Canada and the United States have exchanged import data; the import data of one partner country are used to derive the export data of the other. Exports to the Unites States account for three quarters of Canada's export trade. This procedure is used for all of Canada's exports to the United States except exports of natural gas and electricity. These two commodities are recorded directly from Canadian sources in both Canadian and U.S. customs data.
Data for Canada's exports Non-U.S. destinations are compiled by Statistics Canada from B13A forms and G7 Electronic Data Interchange Export Reporting program received via the Canada's Border Services Agency and from Summary Reports and Canadian Automated Export Declarations (CAED) submitted directly to Statistics Canada.
The program is based on a concordance of HS codes to NAICS codes. Every year for exports and every month for imports, HS codes are birthed or terminated. The history of HS codes and their association to NAICS codes was validated through time with the successive amendments to the two classifications.
Business rules were performed on both import and export HS to NAICS concordances. For example, where there are distribution factors, they must sum to one.
The values obtained by NAICS groupings were confronted with the HS chapters with the largest trade value to verify consistency.
No imputation was done.
This methodology type does not apply to this statistical program.
Totals of imports and exports by industry must match totals of imports and exports by HS and by North American Product Classification System (NAPCS).
Statistics Canada is prohibited by law from releasing any information it collects which could identify any person, business, or organization, unless consent has been given by the respondent or as permitted by the Statistics Act. Various confidentiality rules are applied to all data that are released or published to prevent the publication or disclosure of any information deemed confidential. If necessary, data are suppressed to prevent direct or residual disclosure of identifiable data.
Revisions and seasonal adjustment
Since Canadian imports and exports by industry is a recompilation by NAICS of Canadian imports and exports by commodity, the data are submitted to the same revision process.
The statistical program is derived from a mapping of HS codes to NAICS codes. Every effort is made to ensure that each HS in the concordance is assigned to the right NAICS grouping. The administrative data used to recompile imports and exports by industry are considered to be complete and accurate. Any anomalies or inconsistencies detected are verified with the source, and where necessary, adjustments are made to reconcile data with the conceptual framework of the series. The administrative agencies used are considered to be the best source available.
