Introduction
China and India are the two global powerhouses when it comes to the production of sildenafil citrate powder. Together, they account for more than 80% of worldwide API exports (China Customs & India Export Data, 2024). For B2B buyers—whether pharmaceutical companies, nutraceutical OEMs, or regional distributors—the choice of supplier can determine both the success of product launches and compliance with regulatory requirements.
This guide highlights the top sildenafil citrate powder suppliers in China and India, how they differ, and what you should check before signing a contract.

Why China and India Dominate the Market
China’s Leadership
China produces an estimated 70% of global sildenafil API exports. Provinces like Zhejiang and Jiangsu house state-of-the-art GMP factories that operate at massive scale.
- Advantages: lowest production costs, flexible MOQ (1–25 kg), fast lead times.
- Considerations: buyers must carefully verify documentation (DMF, GMP).
India’s Strength
India contributes less volume but is strong in regulated market compliance. Many Indian manufacturers hold US DMF and EMA CEP filings, making them reliable for pharmaceutical companies targeting Western markets.
- Advantages: robust compliance, WHO-GMP approvals, strong documentation support.
- Considerations: prices are generally $50–$100/kg higher than Chinese factories.

How to Verify Supplier Legitimacy
- Cross-Check DMF/CEP Filings
Search FDA’s DMF database or EMA’s CEP list to ensure the supplier’s documents are valid. - Request Third-Party Test Results
Always ask for HPLC purity reports from independent labs. - Audit via Video or On-Site
Many buyers request virtual factory tours to verify production facilities. - Check Trade Records
Use customs data (e.g., Panjiva, ImportGenius) to see if the factory has exported sildenafil before.

Pricing Comparison: China vs. India
- China (FOB): $450–$600/kg for ≥99% purity. MOQ often flexible (1–5 kg).
- India (FOB): $500–$700/kg for ≥99% purity. MOQ typically ≥25 kg.
- US/EU Distributors: $800–$1200/kg due to regulatory overhead.
In summary:
- Choose China if price and speed are your main concerns.
- Choose India if compliance and Western market regulatory approval are priorities.
Risks and Red Flags
- Unrealistically low prices (<$300/kg) → often indicates counterfeit or low-purity batches.
- No documentation provided upfront → high compliance risk.
- Unwillingness to send samples → lack of confidence in product quality.
