Thirty years of one thing, done well
Shenzhen Oriental Pharmaceutical Co., Ltd. was established in 1995 as the API arm of Happy Industrial (Hong Kong) Investment Group. We research, manufacture and export specialty active pharmaceutical ingredients and advanced intermediates, with a focus on sympathomimetic, antihistamine, CNS and metabolic molecules for regulated markets.
Real GMP production and quality control
Every photograph below was taken at our Shenzhen manufacturing site — final-form packaging in the cleanroom, the QC laboratory and the synthesis floor.










A group behind every order
Oriental is backed by an integrated group covering manufacturing, trade and investment.
Shandong Weifang Happy Pharmaceutical
A modern GMP production base, providing capacity and innovation support.

What we stand for
Compliance first
We only sell what we can document and defend in an audit.
Quality as product
For an API, the quality system is what the customer actually buys.
Long-term partnership
We grow with a handful of serious partners, not a thousand one-off deals.
