hs code was dropped in 12.0 however it shouldn't have been (commit 2d738f8563). commit 498dbc548b created a new module in order to avoid losing hscode for existing database during migration.
This commit set it back as before.
closesodoo/odoo#29167
Purpose
=======
- product form is a bit disorganized with fields showing up at wrong place:
- inventory tab for services -> to remove
- subscription & events fields under Invoicing tab
- inventory tab is not structured
- invoicing and bill control fields are not grouped together
- etc.
HS Code is a standardized code used to describe products categories, and
facilitate customs clearance.
(https://en.wikipedia.org/wiki/Harmonized_System)
Some international transporters require HS codes and use them. We allow
users to store them on product.template's.
