packaging capsules factory

Buyers must distinguish between Gelatin (Bovine/Porcine) and Vegetable-based (HPMC/Pullulan) capsules. For pharmaceutical or nutraceutical use, ensure the material is BSE/TSE-free and meets USP/EP (United States/European Pharmacopoeia) standards. If targeting eco-conscious markets, verify the availability of biodegradable or compostable polymers.

Technical compatibility is critical. You must confirm the standard sizing (000, 00, 0, 1, 2, 3, 4) and the locking mechanism design (e.g., Snap-Fit or Coni-Snap) to prevent splitting during high-speed filling. Request a technical drawing and a small batch of test samples to run through your specific encapsulation machine before placing a bulk order.

A professional factory should hold GMP (Good Manufacturing Practice) and ISO 9001 certifications at a minimum. For food-grade or supplement capsules, FDA registration, HALAL, and KOSHER certifications are often mandatory to meet international consumer requirements and customs regulations.

If your product is acid-sensitive, you must source Enteric-Coated or Delayed-Release capsules that bypass the stomach. For liquid fills, ensure the factory provides leak-proof sealing technology or 'banded' capsules. Always verify the moisture content (typically 13-16% for gelatin) to ensure stability during storage.

Capsules are highly sensitive to temperature and humidity. You should negotiate for climate-controlled shipping (Reefer containers) or use thermal blankets and desiccants within the packaging. Ensure the factory uses heavy-duty, moisture-barrier corrugated boxes with internal food-grade liners.

Avoid focusing solely on the unit price. Negotiate the defect rate tolerance (standard is usually <0.01%) and define clear compensation terms for brittle or deformed capsules. Use Made-in-China.com's Secured Trading services to ensure payment is only released after a successful third-party pre-shipment inspection.

Beyond the standard Invoice and Packing List, you will likely need a Certificate of Analysis (COA) for every batch, a Health Certificate, and a Non-GMO Statement. Check your local country's HS Code classification (often under Chapter 96 or 19) to determine specific import duties and VAT.

Utilize the 'Audited Supplier' reports on Made-in-China.com, which provide verified data on factory floor space, production capacity, and machinery. Request a live video tour of the cleanroom facilities (Class 100,000 or higher) to ensure they meet hygiene standards for pharmaceutical-grade production.
