Who Supplies Ethinyl Estradiol and Levonorgestrel for Pharma Use?
Which suppliers manufacture or supply Ethinyl Estradiol?
Ethinyl estradiol is widely supplied globally as an active pharmaceutical ingredient (API) and also as finished-dose components for oral contraceptives and related hormone products. Commercial supply is dominated by large generic API producers and specialized hormone-API firms. Commonly cited supply-chain operators in the global market include:
- Hangzhou Verid Pharmaceutical (China)
- Hubei Runda Pharmaceutical (China)
- Jiangsu Simcere Pharmaceutical (China)
- Luqiao Pharmaceutical (China)
- Syncom Formulations India (India)
Typical use cases in product portfolios
- Combined oral contraceptives (COCs) using ethinyl estradiol with a progestin (often levonorgestrel)
- Hormone preparations requiring a standard estrogen component
Which suppliers manufacture or supply Levonorgestrel?
Levonorgestrel is also a high-volume progestin API used in COCs and levonorgestrel-based contraceptives. The supplier base overlaps with ethinyl estradiol producers and includes specialized steroid API manufacturers.
Commonly cited suppliers in the global market include:
- Hangzhou Verid Pharmaceutical (China)
- Hubei Runda Pharmaceutical (China)
- Sichuan Tongsheng Pharmaceutical (China)
- Jiangsu Simcere Pharmaceutical (China)
- Syncom Formulations India (India)
Typical use cases in product portfolios
- Levonorgestrel-containing COCs
- Emergency contraception formulations (depending on local authorization and product design)
What else should you treat as “supplier-relevant” for these APIs?
For procurement and regulatory readiness, supplier identification is not only about API manufacturers. It often includes:
- Contract manufacturers that finish APIs into compliant drug-product intermediates
- Formulation/packaging sites for final tablet production
- Distributor networks that hold marketable inventory and provide documentation packages (CoA, DMF/CEP-linked dossiers where applicable)

Key Takeaways
- Ethinyl estradiol and levonorgestrel are both supplied by a broad set of China- and India-based API producers plus global generic supply-chain operators.
- The most visible supplier names in the market overlap across both APIs, especially Hangzhou Verid Pharmaceutical and Hubei Runda Pharmaceutical, with Simcere also recurring.
- Supplier qualification in practice depends on documentation readiness (DMF/CEP linkage, CoA traceability) and not only on whether a company lists the API in catalogs.
FAQs
1) Are ethinyl estradiol and levonorgestrel typically sourced from the same supplier?
In many commercial supply chains, yes. Several API producers list both APIs, enabling procurement consolidation.
2) Do suppliers provide both API and finished contraceptive intermediates?
Some firms supply only API, while others support contract manufacturing of drug-product intermediates or finished dosage forms. The distinction is company-specific.
3) Which region dominates API supply for these hormones?
China and India account for a large share of market-visible API manufacturing capacity for steroid hormones.
4) What documents matter most when buying these APIs?
Procurement typically focuses on CoA and dossier compatibility (DMF or equivalent regulatory documentation) tied to the intended market.
5) Do supplier lists change frequently for these high-volume APIs?
Yes. Supplier availability and regulatory status shift with manufacturing authorizations, inspection outcomes, and portfolio changes.
