wholesale empty gelatin capsules Manufacturers

When sourcing gelatin capsules, the most critical factor is compliance with pharmaceutical and food safety standards. You must ensure the supplier holds GMP (Good Manufacturing Practice) certification and ISO 9001. For international trade, products should meet USP (United States Pharmacopeia) or EP (European Pharmacopoeia) standards. Additionally, if you are targeting specific markets, verify Halal or Kosher certifications to ensure the bovine or porcine gelatin used meets religious dietary requirements.

Focus on the disintegration time, which should typically be less than 15 minutes in gastric juice. Check the filling rate efficiency; high-quality capsules should have a loss rate of less than 0.01% on high-speed filling machines. Also, verify the moisture content, which for gelatin capsules should strictly stay between 13% and 16% to prevent brittleness or softening. Request a Certificate of Analysis (COA) for every batch to confirm these parameters.

Empty capsules come in standard sizes ranging from 000 (largest) to 5 (smallest), with Size 0 and Size 00 being the most popular for supplements. Suppliers on Made-in-China.com often offer customization such as axial or radial printing (logo/dosage info) and a wide array of custom colors (opaque, transparent, or pearlescent). Ensure the pigments used are FDA-approved or reach-compliant food-grade colorants.

Gelatin is highly sensitive to temperature and humidity. You must confirm that the supplier uses temperature-controlled warehousing and specialized packaging, such as antistatic plastic bags inside 5-layer corrugated cartons. The ideal storage condition is 15°C to 25°C with a relative humidity of 35% to 65%. Failure to maintain these conditions during transit can lead to capsule deformation or sticking.

The biggest risk is Customs Seizure due to animal byproduct regulations. Since gelatin is derived from animal collagen, many countries require a Veterinary Health Certificate. Always check if your country has restrictions on bovine-derived products from specific regions due to BSE (Bovine Spongiform Encephalopathy) concerns. Using a reputable platform like Made-in-China.com allows you to vet suppliers who are experienced in providing the necessary export documentation.

To mitigate financial risk, utilize secured payment terms and consider third-party pre-shipment inspections. Request a production sample before the bulk run and a shipping sample from the actual lot being sent. This ensures the 'Wholesale' quality matches the 'Sample' quality. For long-term stability, negotiate a Quality Assurance Agreement that defines compensation protocols for defective rates exceeding 0.3%.

For large wholesale volumes, Sea Freight with Reefer Containers (Refrigerated) is highly recommended to prevent the gelatin from melting in tropical transit zones. For smaller trial orders via Air Freight, ensure the pallets are wrapped in thermal insulation blankets. Avoid shipping during peak summer months if climate-controlled logistics are not available, as high heat can ruin an entire shipment of empty capsules.
