The choice of material is critical for product stability. Type I Borosilicate glass is preferred for injectables due to its high chemical resistance. For oral solids, High-Density Polyethylene (HDPE) is the industry standard because of its excellent moisture barrier properties and impact resistance. If transparency is required with break resistance, Polyethylene Terephthalate (PET) is the ideal choice.

Buyers must verify that suppliers hold ISO 15378 certification, which specifically addresses primary packaging materials for medicinal products. Ensure the products comply with USP <661> (United States Pharmacopeia) for plastic packaging or USP <660> for glass. For child-resistant packaging, look for ASTM D3475 standards to ensure the safety of the closure systems.

Key features include UV protection, typically achieved through amber-colored materials which filter out harmful light wavelengths. Additionally, evaluate the Child-Resistant Closures (CRC) and Tamper-Evident (TE) bands to ensure patient safety and product integrity. For liquid medicines, ensure the neck finish is compatible with standardized droppers or pump inserts.

Request a Vacuum Leak Test report from the supplier to confirm the seal integrity. For bulk orders, it is essential to check the wall thickness consistency using ultrasonic gauges to prevent weak spots that could lead to breakage during high-speed filling lines. Always request a Certificate of Analysis (CoA) for every batch produced.

The primary risk is contamination during transit. Ensure the supplier uses double-layer PE bag inner packaging within a clean-room environment (Class 100,000) before sealing the outer cartons. Another risk is deformation of plastic bottles due to high temperatures in shipping containers; specify temperature-controlled shipping or avoid peak summer routes if using thin-walled PET.

Focus on mold ownership and maintenance. If you require a custom shape, clarify that the intellectual property of the mold belongs to you. Negotiate a staged payment plan (e.g., 30-40-30) where the final payment is only released after a third-party pre-shipment inspection confirms the dimensions and microbial limits meet your specifications.

Medicine bottles are often classified under HS Code 392330 (Plastics) or 701090 (Glass). Ensure your supplier provides a Food Grade Declaration or Drug Master File (DMF) number, as customs in many regions (like the US or EU) may flag these items for medical compliance checks. Using Palletized Shipping is highly recommended to reduce manual handling and minimize the risk of crushing.

Utilize the Secured Trading services on Made-in-China.com to protect your funds. Always conduct a Factory Audit—either virtually or via a third-party agency like SGS—to confirm the supplier actually operates a GMP-compliant facility and isn't a middleman trading company, which is vital for pharmaceutical supply chain traceability.
