empty gelatin capsules

When sourcing empty gelatin capsules, the most critical factor is compliance with international pharmacopoeia standards such as USP (US Pharmacopeia), EP (European Pharmacopoeia), or ChP (Chinese Pharmacopoeia). You must ensure the supplier holds GMP (Good Manufacturing Practice) certification and ISO 9001. For specific markets, verify Halal and Kosher certifications, as these are essential for religious compliance and broader consumer acceptance.

Empty gelatin capsules come in standard sizes ranging from 000 (largest) to 5 (smallest). You should select the size based on the bulk density of your powder and the required dosage weight. While standard gelatin is derived from bovine bone or hide, ensure the supplier provides a BSE/TSE-free certificate to guarantee the raw materials are safe and free from bovine spongiform encephalopathy.

To prevent machine downtime, focus on the disintegration time (typically <15 minutes) and moisture content (standard is 13%-16%). If the moisture is too low, capsules become brittle; if too high, they soften. Additionally, check the locking force and brittleness rating to ensure they can withstand the high-speed mechanical stress of industrial filling lines without cracking or dimpling.

Gelatin is highly sensitive to environmental changes. They must be stored in a controlled environment with a temperature between 15°C and 25°C and a relative humidity (RH) between 35% and 65%. Failure to maintain these conditions during transit or storage will lead to capsule deformation, sticking, or brittleness, rendering them unusable for filling.

Since capsules are temperature-sensitive, you should insist on refrigerated containers (Reefer containers) for long-distance sea freight, especially when crossing tropical zones. Ensure the packaging includes anti-static liners and heavy-duty corrugated boxes. It is highly recommended to place temperature and humidity data loggers inside the shipment to monitor conditions throughout the journey for insurance and quality claims.

Customs authorities often categorize empty capsules under strict regulatory codes. Ensure the supplier provides a comprehensive Certificate of Analysis (COA) for every batch and a Health Certificate. Incomplete documentation can lead to lengthy customs seizures or mandatory laboratory testing at the port of entry, significantly increasing your lead time and costs.

When using Made-in-China.com, prioritize Audited Suppliers who have undergone third-party onsite inspections. Negotiate a contract that includes a pre-shipment inspection (PSI) clause. Request a retention sample from the specific production lot you are buying, so you have a benchmark for quality if a dispute arises regarding the filling success rate or chemical composition.

For large-scale B2B orders, use Secured Trading services provided by the platform or Letter of Credit (L/C) for high-value transactions. This ensures that payment is only released upon the presentation of valid shipping documents and compliance certificates, protecting your capital against non-delivery or sub-standard goods.
