X-ray window price

The price of an X-ray window is primarily determined by its Lead Equivalent (Pb thickness), typically ranging from 1.5mm Pb to 3.0mm Pb for standard diagnostic rooms. You must verify the density of the lead glass, which should generally be above 4.2 g/cm³ to ensure effective radiation attenuation. Additionally, the Light Transmittance should exceed 85% to ensure clear visibility for medical staff, and the surface finish must be free of bubbles or inclusions that could compromise shielding integrity.

Buyers must ensure the product meets international safety standards such as IEC 61331-2:2014 (Protective devices against diagnostic medical X-radiation). For the US market, compliance with 21 CFR 1020.30 is essential, while the EU market requires CE Marking and adherence to EN 61331. Always request a Radiation Protection Test Report from the supplier to validate that the glass provides the stated lead equivalence at specific kVp levels.

Beyond the initial unit price, consider the customization costs for specific dimensions, as non-standard sizes often carry a premium. Packaging and crating fees are significant because lead glass is extremely heavy and fragile, requiring specialized fumigated wooden crates. To optimize costs, look for suppliers on Made-in-China.com who offer integrated window frames, which reduces on-site installation labor and ensures no radiation leakage at the edges.

The biggest risk is physical breakage during transit due to the material's high density and brittleness. Ensure the contract specifies vacuum packaging and shock-absorption materials. Another risk is oxidation (staining); lead glass is sensitive to moisture. You should demand anti-oxidation coatings or moisture-proof silica gel packs within the packaging to prevent the glass from turning cloudy during sea freight.

Utilize Trade Assurance services provided by Made-in-China.com to protect your payment until delivery is confirmed. Negotiate a 30% deposit and 70% balance payment after providing a third-party inspection report (such as SGS or TUV). Explicitly define the allowable tolerance for lead equivalence in the contract to avoid receiving sub-standard shielding materials.

Due to the weight, Sea Freight (LCL or FCL) is the most cost-effective method, but ensure the supplier provides a Material Safety Data Sheet (MSDS) if required by the carrier. Correct HS Code classification (typically 7016.90 or 7003.19) is vital to avoid customs delays. For the final mile, ensure the destination warehouse has heavy-duty lifting equipment (forklifts), as a single large X-ray window can weigh several hundred kilograms.
