Empty color capsules

Buyers must choose between Gelatin (Animal-based) and HPMC (Vegetable-based). Gelatin is cost-effective and has a long history of use, but HPMC capsules are essential for Vegan, Halal, or Kosher certifications. Additionally, HPMC is better for moisture-sensitive ingredients as it has a lower water content (4-6%) compared to Gelatin (13-16%).

Ensure the supplier complies with GMP (Good Manufacturing Practice) standards. For international trade, look for FDA registration, ISO 9001, and COA (Certificate of Analysis) for every batch. If targeting specific markets, verify Halal or Kosher certifications to ensure the coloring agents and base materials meet religious dietary laws.

Request a detailed pigment list to ensure all dyes are food-grade or pharmaceutical-grade (e.g., Titanium Dioxide-free options are increasingly popular in the EU). To prevent batch-to-batch color variation, ask the supplier for their Delta E color tolerance specifications and request physical samples before placing a bulk order.

The locking mechanism (e.g., dual-ring or dimple locks) is critical to prevent leaking or premature opening during high-speed filling. Ensure the size (000, 00, 0, 1, 2, 3, 4) is compatible with your specific encapsulation machinery and that the weight variation is within the standard range (usually ±7.5%).

Capsules are highly sensitive to temperature and humidity. Shipping must be done in temperature-controlled containers (Reefer) maintained between 15°C and 25°C with humidity at 35-65%. Failure to do so can lead to brittleness, stickiness, or deformation, rendering the product unusable.

Utilize secure payment terms and consider third-party factory audits to verify the supplier's production capacity. For reliable sourcing, platforms like Made-in-China.com offer verified supplier profiles and Secured Trading services to protect your payment until the goods are confirmed.

Empty capsules are often classified under HS Code 190590. Be aware that some countries require BSE/TSE-free certificates for gelatin capsules to prevent animal-borne diseases. Always check the import tariffs and Health Department regulations of the destination country to avoid shipment seizures.

Focus on Annual Volume Commitments rather than one-off orders to secure 10-20% discounts. Negotiate for customized printing (logo/brand) to be included in the unit price for large volumes, and request buffer stock agreements to ensure a stable supply chain during peak seasons.
