从China供应商批发进口8in 6 Pin Pci Express Power Extension Cable — FOB条款

Sourcing 8in 6 pin PCI Express Power Extension Cable from STC-Cable - China Import Guide

Before ordering from STC-Cable, verify the company's business licence, export registration, and whether it holds ISO 9001 or IATF 16949 quality certification relevant to cable assembly. Request material certificates for copper purity and RoHS compliance for both conductors and connector housings. If the product targets North American or European markets, confirm whether the cable assembly or its components carry UL, CSA, or CE marking. Inspect sample connectors under magnification for flash, proper crimp compression, and housing gate marks that indicate moulding quality. Test continuity and insulation resistance with a multimeter, and verify pin-to-pin mapping against the PCI-SIG specification.

Shipping and Incoterms need explicit confirmation. The supplier does not list available terms; common arrangements from Shenzhen cable suppliers include FOB Shenzhen Shekou or Yantian, CIF destination port, or EXW Songgang factory. Sea freight to European major ports typically takes 25-35 days, to US West Coast 14-21 days, and to US East Coast 30-40 days. Air freight reduces transit to 5-8 days but increases cost substantially for low-value cable goods. Payment terms commonly requested by Chinese suppliers include 30 percent deposit with 70 percent against bill of lading, though established relationships may negotiate documents against payment or open account. Avoid Western Union for initial orders, and use escrow or letter of credit for amounts exceeding your risk threshold.

Incoming quality inspection should verify conductor gauge with a micrometre or by stripping and measuring strand diameter and count. Perform continuity testing on all six pins and measure DC resistance with a four-wire measurement for accuracy. Subject samples to bend testing at specified radius to check for conductor work-hardening or insulation cracking. For production batches, implement sampling per AQL 1.0 or 2.5 depending on your quality agreement. Retain batch records with supplier lot numbers for traceability. If the cable will support high-value GPU deployments, consider third-party pre-shipment inspection at the factory, including dimensional checks, material analysis, and functional load testing. Document all specifications agreed with STC-Cable in a purchase order with referenced drawings and acceptance criteria to support any future quality disputes.
