New American Capsule Duties Raise Pharma Sourcing Costs
Unfilled water-soluble hard empty capsules from Brazil, China, India, and Vietnam face stacked duties up to 88 percent.
Hpmc Capsules
Plant Polymer
Semi-synthetic shells derived from wood pulp or cotton fibers offer a non-animal alternative for the encapsulation of dietary supplements and pharmaceuticals. Health-conscious consumers often prefer hpmc capsules due to their vegetarian origin and lack of preservatives. These units maintain low moisture levels, which makes them suitable for hygroscopic ingredients that might degrade in gelatin.
The material remains stable across a wide range of temperatures and humidity levels.
Material Advantage
Low water content prevents the shell from stealing moisture from the filling, which protects sensitive compounds from oxidation. Manufacturers use hpmc capsules to house probiotics and herbal extracts that require a dry environment to remain effective. Unlike animal-based shells, these containers do not undergo cross-linking, ensuring a predictable dissolution rate even after long periods of storage.
This stability simplifies the global distribution of products to regions with diverse climates. The absence of allergens and religious restrictions further expands the market reach for products using this delivery format.
Thermal Stability
Resistance to heat allows these containers to withstand the rigors of high-speed filling and packaging without deforming. While gelatin might melt or soften, hpmc capsules retain their structural integrity in challenging environments. This property is particularly useful during the friction-heavy process of mechanical capping.
