6-Step Automotive Inspection Protocol

Component Verification & Documentation

Comprehensive verification of part numbers, specifications, and manufacturing documentation to ensure authenticity and compliance.

Part number verification against specifications
OEM vs aftermarket identification
Manufacturing date and batch code validation
Material composition certification review
Supplier documentation and traceability
Packaging authenticity verification
Country of origin confirmation

Dimensional & Tolerance Analysis

Precision measurement and tolerance verification using calibrated equipment to ensure perfect fit and function.

Critical dimension measurement with calipers/micrometers
Thread pitch and diameter verification
Surface finish and roughness testing
Geometric dimensioning and tolerancing (GD&T)
Hole patterns and mounting point accuracy
Weight and mass verification
Clearance and interference fit analysis

Functional Performance Testing

Comprehensive functional testing to verify operational performance under various conditions and loads.

Electrical component continuity and resistance
Mechanical movement and articulation testing
Pressure and flow rate verification (fluid components)
Torque and force measurement
Temperature resistance and thermal cycling
Vibration and shock resistance testing
Seal integrity and leak testing

Safety & Regulatory Compliance

Verification of safety-critical features and regulatory compliance for US automotive standards.

DOT compliance marking verification
FMVSS standard compliance checking
Safety-critical component identification
Material safety data sheet (MSDS) review
California Air Resources Board (CARB) compliance
EPA emissions compliance verification
NHTSA recall database cross-reference

Material & Surface Quality

Detailed analysis of material properties, surface conditions, and coating integrity for durability assessment.

Material hardness and strength testing
Surface coating thickness and adhesion
Corrosion resistance and salt spray testing
UV resistance and weathering assessment
Chemical resistance and compatibility
Wear resistance and abrasion testing
Paint and finish quality evaluation

Packaging & Documentation

Final verification of packaging integrity, labeling accuracy, and documentation completeness for Amazon FBA compliance.

Individual part packaging protection
Barcode scanning and placement verification
Installation instruction completeness
Warranty and certification documentation
Amazon FBA labeling requirements
Master carton strength and dimensions
Hazmat classification and labeling (if applicable)
