从China供应商批发进口30 Titanium Filter With M36 Interface — FOB条款
Sourcing 30 Titanium Filter With M36 Interface from Baoji Yinggao Metal Materials Co., Ltd. - China Import Guide
Before placing an order with Baoji Yinggao Metal Materials Co., Ltd., verify that the 55 micrometre pore rating matches your process requirements by requesting a sample element for bubble point and diffusion flow testing. Confirm the exact thread form of the M36 interface against your housing drawing, including pitch, thread class, and engagement length. Check whether Baoji Yinggao can provide material certificates with chemical composition traceable to a recognised titanium sponge source, as this is standard for aerospace and medical applications but not universally available from all Chinese producers. Given the zero percent response rate shown, test communication channels thoroughly before committing deposits.
Logistics from Baoji, Shaanxi Province, typically routes through Xi'an or Shanghai for ocean export. Confirm Incoterms with Baoji Yinggao, as ex-works Baoji differs substantially from FOB Shanghai in cost and complexity. Standard sea freight to European or North American ports takes 25 - 40 days depending on transshipment. Ask whether the supplier has experience with export documentation including commercial invoices, packing lists, certificates of origin, and material safety data sheets. Payment terms for new buyers from Chinese metal product suppliers often require 30 - 50% advance with balance against copy of bill of lading; letter of credit terms may be negotiable for larger orders but expect higher costs.
Upon arrival, inspect the filter element for dimensional conformity using calibrated gauges, particularly the M36 thread and overall length. Perform a bubble point test with isopropanol or water to verify pore integrity and absence of cracks from transit vibration. Check packaging integrity for moisture ingress. For critical applications, engage a third-party inspection agency such as SGS or BV to witness factory testing before shipment, or to conduct pre-shipment inspection at the port. Retain all documentation for regulatory compliance audits. If the application involves pharmaceutical or food contact, validate that the supplied certificates match the actual batch markings on the element body.
