x ray grid price

The price of an X-ray grid is primarily determined by its Grid Ratio (e.g., 8:1, 10:1, 12:1) and Grid Density (lines per cm/inch). Higher ratios provide better scatter radiation absorption but require higher radiation doses and precision, leading to increased manufacturing costs. You must also specify the Focal Distance (Focusing Range); fixed-focus grids are generally more expensive than parallel grids due to the complex alignment of lead strips.

Grids typically use Lead (Pb) for the strips, but the interspace material significantly affects performance and price. Aluminum interspace grids are durable and moisture-resistant, making them ideal for high-kVp imaging, while Fiber or Organic interspace grids are preferred for low-kVp applications (like mammography) to reduce patient dose. Choosing the wrong material can lead to image artifacts or premature degradation, increasing the total cost of ownership.

Suppliers must adhere to international medical device standards such as ISO 13485 (Quality Management Systems for Medical Devices). Ensure the product has CE Marking (EU) or FDA Registration (USA) depending on your target market. For B2B buyers on Made-in-China.com, it is critical to request IEC 60627 compliance reports, which verify the physical and performance characteristics of anti-scatter grids.

Request a uniformity test report to ensure there are no defects in the lead strip distribution, which causes 'grid lines' on images. You should also ask for High-Resolution Digital Photos of the product labeling, which must include the convergence line, focal distance, and tube side indicator. For high-value orders, hiring a third-party inspector to perform a visual and X-ray performance check is a standard industry safeguard.

X-ray grids are extremely fragile and sensitive to physical impact and moisture. The primary risk is structural warping or internal strip misalignment during transit. Ensure the supplier uses vacuum-sealed anti-static packaging and reinforced wooden crates with 'Fragile' and 'Keep Dry' markings. Always negotiate Incoterms like CIF or CIP to ensure the goods are insured until they reach your destination.

Focus on Volume-Based Tiered Pricing. Suppliers often offer a 10-15% discount for orders exceeding 50 units. Additionally, discuss Long-term Supply Agreements; by committing to an annual volume, you can lock in prices against fluctuations in lead (raw material) costs. Always ask if the price includes customized dimensions, as standard sizes (e.g., 14x17 inch) are usually cheaper than bespoke sizes.

Utilize Secured Payment Services provided by Made-in-China.com to ensure funds are only released after the bill of lading is verified. Avoid direct wire transfers to unknown accounts. For first-time purchases, use a Letter of Credit (L/C) for large sums to mitigate financial risk and ensure the supplier meets all documentary requirements before payment.

Medical components often fall under specific HS Codes (e.g., 9022.90), which may be subject to medical device import duties or VAT exemptions depending on the country. Verify if your country has a Free Trade Agreement (FTA) with China to reduce tariffs. Ensure the supplier provides a Certificate of Origin to facilitate customs clearance and avoid costly delays at the border.
