Catalog status
Scope. "Available for inquiry" is not a stock claim. Operating tier is a catalog-merchandising priority. Development phase and program context are shown only where the reviewed catalog source provides a mapping; they describe the chemistry platform and do not claim that OROGO supplies the named program. Annual demand is a planning-model estimate from the reviewed demand dataset, not OROGO sales, inventory, a guaranteed market size or a supply commitment.
