Trade Data

Question

A prof is asking for the following:

- Canadian exports by country by 2 digit NAICS, for 1988-present, at a quarterly frequency; also similar data but for manufacturing at the 3 digit NAICS level

- Canadian exports at the 4-digit SIC level to the countries of the U.S., U.K., Japan, China, France, Germany, and the
Netherlands (there might be a few more later), from 1985 to the latest possible year as I think SIC data ends in 2002), at an
annual frequency.

I'm at a loss here; the prof said he was referred to me by someone at STC, which suggests that I should have access to what he wants, but I'm not finding anything. Suggestions would be welcomed!

Answer

Although data is not collected at the NAICS level, it is collected at the SCG/HS/CT code level. We do have an excel spreadsheet that offers the correspondence between HS/CT code and NAICS (it is found on the FTP under dli/standard_classifications/ct-naics). Documentation is available to explain it in a little more detail.

The spreadsheet maps to the five or six digit NAICS - not two as requested.
