Gelatin hard capsule manufacturers

Selecting the right capsule requires a balance of material purity, dissolution rates, and mechanical stability. Buyers must prioritize BSE/TSE-free certification to ensure the gelatin is sourced from healthy, traceable bovine or porcine origins. For high-speed filling machines, ensure the capsules have reinforced dome structures and pre-locking features to prevent breakage or leakage during the manufacturing process.

Products must adhere to international pharmacopoeia standards such as USP (US Pharmacopeia), EP (European Pharmacopoeia), or ChP (Chinese Pharmacopoeia). Key metrics include moisture content (typically 13%-16%), disintegration time (usually <15 minutes), and microbial limits. Ensure the supplier provides a Certificate of Analysis (COA) for every batch and holds GMP (Good Manufacturing Practice) and ISO 9001 certifications.

Gelatin is highly sensitive to humidity and temperature. Ideal storage conditions are 15°C to 25°C with a relative humidity of 35% to 65%. If the environment is too dry, capsules become brittle and crack; if too humid, they become soft and sticky. Buyers should verify that suppliers use anti-static, moisture-proof packaging (such as aluminum foil bags) for international transit.

Suppliers on Made-in-China.com offer extensive customization, including size variations (000, 00, 0, 1, 2, 3, 4), color matching (using FDA-approved pigments), and axial or radial printing for brand identification. For light-sensitive fillings, request opaque capsules with titanium dioxide or natural opacifiers to protect the internal ingredients from UV degradation.

The biggest risk is customs rejection due to animal byproduct regulations. Many countries require a Health Certificate or Veterinary Certificate to prove the gelatin is free from Mad Cow Disease (BSE). Always confirm the specific import permit requirements of your local FDA or health authority before the goods leave the factory.

Utilize secured payment terms and consider hiring a third-party inspection agency (like SGS or Intertek) to perform a pre-shipment inspection. On Made-in-China.com, look for Audited Suppliers who have undergone rigorous on-site verification of their production facilities and financial standing.

For long-distance cross-border shipping, especially through tropical zones, use temperature-controlled containers (Reefer containers). If using standard shipping, avoid peak summer months or ensure the cargo is placed below the waterline on the vessel to minimize heat exposure. Always include data loggers in the shipment to monitor temperature and humidity fluctuations during transit.

Standard lead times are 10-20 days. For customized colors, the Minimum Order Quantity (MOQ) is usually higher (e.g., 1 million pieces). Negotiate for staggered delivery schedules if you have limited climate-controlled warehouse space, and ask for volume-based discounts—prices typically drop significantly when ordering in full container loads (FCL).
