What buyers should verify before placing sample or bulk orders
This page supports procurement due diligence. Certificate numbers, validity, test records and shipment evidence should be confirmed from current sales files.
Certification evidence
Request current certificate scans, certificate number, issuing body, expiry date and covered business scope.
Product test evidence
For sensor orders, ask for inspection notes such as visual check, connector match, resistance/function check or batch QC record.
Factory and process evidence
Use factory photos, test equipment photos, QC workflow and packaging records to confirm capability.
Order evidence
Confirm PI, quantity, packaging, shipping method, lead time, destination and after-sales contact before payment.
OE/OEM numbers and vehicle names are used for cross-reference and sourcing identification only. SHR Autoparts does not claim brand authorization or guaranteed fitment unless confirmed in writing for your sample, connector, voltage, position and application.
Our commitment to quality is backed by internationally recognized certifications and rigorous testing standards.

Quality Control Process
From raw material inspection to final shipment, every step is carefully monitored and documented.
1
Supplier Audit
All component suppliers are audited and qualified. Only approved materials enter our production line.
2
Raw Material Testing
Incoming materials are tested against specifications. Non-conforming materials are rejected.
3
Production Monitoring
Statistical process control (SPC) ensures consistent quality throughout production.
4
100% Final Testing
Every sensor is individually tested for electrical parameters and signal accuracy before packaging.
5
Shipment Verification
Final checks include visual inspection, serial number verification, and proper packaging to prevent transit damage.
