Each market now shows one aggregated status: a market counts as on sale if it has any active record; individual record statuses are shown in the details. The same market can also have several registration records with different statuses, so each market appears only once here; that is a record fact, not a safety judgement.
A missing name is marked in its row only when it is the exception; when most names lack it, the list stays unmarked.

Notes & licences
Status badges summarise the product records held for each ingredient (active / discontinued / withdrawn / unknown), and the market codes after each badge show where that status is recorded. Only some registers publish a status column: CA, ES and MX do; AU and HK have no status column and are recorded as unknown; CN, US, GB, TW and SG records are on the register and marked active.
Class and category names are editorial or AI-assisted translations; only the ATC code and the WHO hierarchy are authoritative.
ATC codes and hierarchy reference the WHO Collaborating Centre for Drug Statistics Methodology ATC/DDD Index (copyright WHOCC; the index itself is not reproduced). Ingredient/strength facts come from the regulator records listed on About.
