Sourcing Insights
Frequently Asked Questions About Capsule Manufacturing
Essential information for procurement professionals and brand managers evaluating our contract encapsulation services.
Our standard production MOQs for custom capsule encapsulation start at 25,000 units per bottle run or equivalent bulk batch sizes. Pilot batches for launch-stage brands can be evaluated individually depending on raw material costs and formulation parameters.
We stock and process two-piece hard shell capsules in both HPMC (Vegetarian) and traditional gelatin (Bovine/Porcine). Available sizes range from 000 (largest) down to 4. We also offer acid-resistant delayed-release shells, liquid-filled hard capsules, and softgels.
Our formulation scientists calculate realistic ingredient overages based on scientific stability data. All filling occurs in humidity- and temperature-controlled cleanrooms to prevent active ingredient degradation during encapsulation.
Yes. We specialize in clean-label formulations utilizing natural excipients (such as organic rice flour, organic acacia gum, and sunflower lecithin) and non-GMO vegetable HPMC shells, avoiding synthetic binders or magnesium stearate when requested.
We supply comprehensive export documentation packages including Certificates of Analysis (COA), Certificates of Free Sale (CFS), GMP Compliance Certificates, Allergen & Non-GMO Statements, BSE/TSE-Free Declarations, and Master Manufacturing Flow Charts.
