Conducted when at least 80% of your order is packed. We verify quantities, workmanship, cosmetics, and functional performance using standard AQL sampling.

Comprehensive Oversight
What Our QC Inspection Service Includes
Rigorous physical, functional, and packaging checks conducted at every stage of the manufacturing cycle.
During Production (DUPRO)
Performed when 20% to 50% of the production run is complete to detect flaws early, verify assembly line consistency, and ensure on-time factory delivery.
Packaging & Barcode Verification
We check carton drop-testing, polybag safety warnings, master carton dimensions, Amazon FNSKU barcodes, and retail presentation for transit safety.
Precision Measurement & Tolerances
Our inspectors utilize precision micrometers, digital calipers, colorimeter swatch matching, and weight scales to confirm exact design compliance.
Functional & Safety Stress Tests
From electrical high-voltage tests to waterproof checks, zipper cycle tests, and drop assessments, we ensure your products perform reliably under real-world use.
Container Loading Check (CLC)
We oversee container stuffing, verify carton counts, inspect maritime container condition for moisture/odors, and witness official customs seal affixing.
Methodical Workflow
How Our QC Inspection Works
A dependable, transparent process that keeps you fully in command of your production overseas.
Checklist Alignment
We configure a tailored inspection protocol detailing your critical product dimensions, tolerances, branding, and testing parameters.
On-Site Deployment
Our qualified QC inspector arrives at the factory anywhere in Guangdong, Zhejiang, or Jiangsu to draw random AQL samples.
Rigorous Testing
The inspector carries out cosmetic reviews, dimensional audits, electrical safety tests, drop simulations, and barcode scans.
24h Verified Report
You receive a detailed digital report with dozens of high-res photos, videos, and Pass/Fail defect tallies before paying your balance.
Prevent Disasters
Why Inspection in China is Non-Negotiable
Once products are loaded onto an ocean container and leave Chinese waters, returning defective units is practically impossible. Catching defects before payment protects your investment.
Protect Customer Reviews & Seller Accounts
Prevent account suspensions on Amazon or e-commerce chargebacks caused by high defect return rates.
Enforce Factory Accountability
Suppliers correct mistakes, rework parts, and replace broken units at their own cost before goods ship.
Maintain 100% Brand Consistency
Ensure that repeat production runs match the exact color, build weight, and finish of your initial golden samples.
Independent Eyes on the Ground
Unbiased reporting with no allegiance to the factory, giving you genuine peace of mind.

Common Questions
Quality Inspection FAQs
How does AQL 2.5 work for sample selection?
Based on ISO 2859-1 tables, for an order of 1,000 units, we randomly draw 80 sample units. The lot passes if major defects are within the statistical threshold (e.g. 5 or fewer), ensuring mathematically sound quality assurance.
Can you test functional electronics and batteries?
Yes. We carry calibrated battery testers, sound meters, digital thermometers, and load testers to verify electronics, charging speeds, and safety compliance.
What if the factory refuses inspector entry?
A refusal is an immediate red flag. We notify you immediately so balance payments are halted while we address the issue with executive factory management.
How far in advance should I book an inspection?
We recommend notifying us 3 to 5 business days before the scheduled completion date to guarantee optimal inspector scheduling and checklist review.
