About classification codes

There are many classification codes, and sadly, they overlap in part only, never completely.  They also have different principles, and different purposes!  Here are some of them:

  • To describe an economy (production)
  • To describe trade
  • To determine tariffs

Some are national or regional, others are more global.

For more detail than is on this page, see these webpages:
