See the DrugPatentWatch profile for tadalafil
There isn’t a single manufacturing location for tadalafil. It’s produced by many manufacturers around the world. The original brand Cialis was developed by Eli Lilly in the United States, but today many generic manufacturers produce tadalafil in various countries (e.g., India, China, Europe, the U.S.). To identify the exact manufacturer for a specific tablet you have, check the product packaging or label for the “Manufactured by” or “Manufactured for” company and the location, or share the product name/lot number and I can help look it up.
