Urine container

B2B buyers should prioritize Polypropylene (PP) for the container body due to its excellent chemical resistance and shatterproof durability. The caps are typically made of High-Density Polyethylene (HDPE) to ensure a leak-proof seal. For specialized diagnostics, ensure the material is non-cytotoxic and metal-free to avoid sample contamination.

Suppliers must hold ISO 13485 certification for medical device quality management. For the US market, FDA 510(k) clearance or registration is mandatory. For the EU, products must comply with the In Vitro Diagnostic Regulation (IVDR 2017/746) and bear the CE Mark. Always verify that the supplier provides a Declaration of Conformity (DoC).

Look for molded-in graduations (in both ml and oz) that are easy to read and will not rub off. A frosted writing surface on the side or cap is essential for patient identification. For vacuum systems, ensure the cap features a secure integrated transfer port that is compatible with standard evacuated tubes to minimize exposure risks for lab technicians.

Containers are available in Non-sterile, EO (Ethylene Oxide) Sterile, or Gamma Radiation Sterile formats. For routine urinalysis, non-sterile bulk packs are cost-effective. However, for microbiological cultures, you must procure individually wrapped sterile containers to ensure clinical validity. Verify the sterility assurance level (SAL 10^-6) with the manufacturer.

Request a 95kPa pressure test report from the supplier. This ensures the container can withstand pressure changes during air or sea freight without leaking. Additionally, specify double-wall corrugated export cartons and palletization with shrink wrap to prevent compression damage during transit.

Focus on Annual Purchase Volume (APV) rather than single-order quantity to secure tier-1 pricing. Ask for free samples (shipping excluded) to conduct a 'leak and thread' test. If you are a long-term buyer, negotiate for customized labeling (OEM) which can be included at no extra cost if the order meets the MOQ of 50,000+ units.

Always use Secured Trading Services on Made-in-China.com to protect your payment until the goods are shipped. Before final payment, hire a third-party inspection agency (like SGS or Intertek) to perform a Random Sampling Inspection focusing on volume accuracy, sterilization pouch integrity, and quantity verification.

Ensure the HS Code (typically 392690) is correctly declared. Provide the customs broker with the Product Specification Sheet, Packing List, and Commercial Invoice that clearly states the 'Intended Use' (e.g., for laboratory use only). Be aware of anti-dumping duties that may apply to plastic products in certain regions.
