GENZYME INTERNATIONAL HOLDINGS UNLIMITED COMPANY
GENZYME INTERNATIONAL HOLDINGS UNLIMITED COMPANY is a Private limited company (Ltd.) registered in Ireland under IE409980, and its current status with Companies Registration Office (CRO) is inactive. The company was incorporated on 26 October 2005 and lists its registered address as Ireland. 1 shareholder is on record for GENZYME INTERNATIONAL HOLDINGS UNLIMITED COMPANY, and since every one of them is a company rather than an individual, this particular filing does not on its own establish an ultimate beneficial owner (UBO) — identifying one would mean tracing the ownership of each shareholding company in turn. This profile is sourced directly from Companies Registration Office (CRO) and was last updated on 21 October 2026.
