Capsule inhaler

When evaluating capsule inhalers (Dry Powder Inhalers - DPIs), you must prioritize the Fine Particle Fraction (FPF) and Emitted Dose (ED), as these determine drug delivery efficiency to the lungs. Ensure the device is compatible with specific capsule sizes (typically Size 3) and features a high-quality piercing mechanism (stainless steel needles) to prevent capsule fragmentation. The internal airflow resistance should be calibrated to the target patient demographic (e.g., low resistance for elderly or pediatric use).

As a medical device, the supplier must hold ISO 13485 certification for medical device quality management. For the US market, FDA 510(k) clearance is essential, while the EU market requires CE Marking (MDR 2017/745). Additionally, ensure the plastic materials used are medical-grade (USP Class VI) and BPA-free to prevent chemical leaching during inhalation.

Request a Life Cycle Test report; a high-quality inhaler should maintain consistent performance for at least 500 to 1,000 uses. You should also ask for In-vitro Bioequivalence studies if the inhaler is intended for a generic drug. Conduct a drop test (usually 1 meter onto a hard surface) to ensure the casing does not crack and the capsule chamber remains functional.

Suppliers on Made-in-China.com often provide OEM/ODM services, including custom color-coding for different medication types (e.g., blue for rescue, green for maintenance). You can also request integrated dose counters, custom logo silk-screening, and specialized blister packaging or retail box designs to meet local pharmacy requirements.

The biggest risk is Customs Seizure due to lack of proper medical registration documents. Always ensure the HS Code (typically 901920) is correctly declared and that the supplier provides a Certificate of Free Sale (CFS). Another risk is contamination during transit; ensure the supplier uses double-layered moisture-proof packaging to maintain device sterility.

Focus on Total Cost of Ownership (TCO) rather than just the unit price. Negotiate for staggered delivery schedules to manage inventory and request a 2-5% defect allowance or replacement clause in the contract. For large orders, aim for a 15-20% discount compared to sample pricing, and use Trade Assurance via Made-in-China.com to secure your payment until quality inspection is passed.

For medical devices, Air Freight is preferred to minimize the time spent in uncontrolled environments, although Sea Freight is more economical for large volumes. If shipping by sea, specify 'Top Loading' to prevent crushing and ensure the containers are climate-controlled if the inhalers are pre-loaded with temperature-sensitive capsules. Always purchase Marine Insurance covering 110% of the cargo value.

Always verify the supplier's Business License and Export Permit through the Made-in-China.com audit reports. Conduct a Pre-Shipment Inspection (PSI) by a third party like SGS or Intertek to verify that the batch meets the agreed-upon AQL (Acceptable Quality Level) standards before the final balance is paid.
