In practice, where you think you should use 003, you should probably
use 021 instead.

Indeed: in UNSD usage it means "the former ruble zone", without regard
to the actual membership of the actual CIS, which is quite unstable:
the Baltics never joined, Ukraine is a de facto but not de jure
member, and Georgia has withdrawn.
