In today’s competitive global market, product quality is more than a requirement — it’s your brand’s reputation. A single quality issue can trigger negative reviews, platform penalties, inventory losses, or even customer churn.
As your reliable China sourcing and quality control partner, Boltidea delivers end-to-end, customizable inspection and quality management services — covering supplier audits, production supervision, laboratory testing, and pre-shipment inspections.

Why Quality Control Matters
Poor materials
Frequent product defects
Lack of supervision
Production deviates from standards
Labeling errors
E-Commerce rejections or fines
Missing test reports
Non-compliance risks
Our structured quality control system helps prevent these issues, allowing you to source confidently and ship smoothly.
Our Five Core Quality Control Services
1. Factory Audit: Selecting Reliable Manufacturers
Pre-cooperation due diligence determines success or failure.
Our senior QC experts conduct on-site supplier audits to assess:
- Factory qualifications & production capacity
- Quality management systems (ISO, BSCI, etc.)
- Technical capabilities & past project experience
- Workforce stability & management efficiency
We can also coordinate independent audits through SGS, Intertek, or BV, ensuring supplier authenticity and reliability.
2. Pre-Production Inspection (PPI): Securing the First Gate
Raw materials define product quality — and cost-driven substitutions are common in manufacturing.
Before production begins, we verify:
- Whether raw materials match the agreed specifications
- Color, texture, and composition consistent with approved samples
- Packaging materials’ durability and compliance
Early-stage control prevents “cheap replacements” and ensures consistency across orders.
3. During Production Inspection (DUPRO): Real-Time Quality Monitoring
Mid-production is the golden window to detect problems early.
Our inspectors conduct on-site line checks to ensure:
- First-article samples meet quality benchmarks
- Workmanship and processes follow standards
- No signs of batch-level defects or deviations
When issues arise, we coordinate immediate corrective actions with the factory — preventing costly mass defects.
📊 Weekly photo reports keep you updated with transparent production progress.
4. Pre-Shipment Inspection (PSI): The Final Quality Gate
Before goods are loaded, our team performs a comprehensive random inspection following the AQL (Acceptable Quality Level) standard, covering:
- Functional testing (assembly, usability, performance)
- Visual defects (scratches, color deviation, stains)
- Packaging integrity (drop, compression, sealing tests)
- Label verification (brand logo, barcode, FBA label accuracy)
We also perform simulated transportation drop tests to ensure products withstand international shipping conditions.
5. Laboratory Testing: Certified & Compliant Products
To meet international compliance standards for EU, US, and global markets, we partner with certified domestic and global laboratories.
