A short checklist before choosing one code over another.
These codes share C MANUFACTURING > 23 Manufacture of other non-metallic mineral products > 23.1 Manufacture of glass and glass products before they diverge.
23.11, 23.12, 23.13, 23.14, 23.15 already list another compared code as related or often confused.
23.11, 23.12, 23.13, 23.14, 23.15 include official exclusions that may point to a better-fitting code.
23.15 have non-exact Rev. 2 to Rev. 2.1 mappings; review old records before migration.
