Superior quality reduces returns, maintenance and operating costs. We always put customers’ interests first and are committed to creating greater business value for you.
INTAKE & VERIFICATION
Intake & Verification
The first step when goods arrive is to go back to the source and verify their identity. From supplier credentials and original packaging to ESD protection, we check every item item-by-item so that every batch is traceable before it enters the warehouse.
- Supplier qualification and authorized supply-chain verification
- Original seals, labels and anti-counterfeiting feature checks
- Batch number, date code and country of origin verification
- ESD protective packaging integrity confirmation
- Moisture Sensitivity Level (MSL) and environmental record review
LAB & INSPECTION

Beyond appearance lie invisible details. Relying on professional testing equipment and standardized procedures, we validate components at multiple levels, stopping cosmetic defects and counterfeits before they enter the warehouse.
- Item-by-item visual check of body, marking and leads
- Review of original labels, country of origin and packaging type
- High-power microscopic magnification inspection
- X-RAY internal structure inspection
