If you’ve ever had a product arrive late, broken, or just wrong — you’re not alone. Most first-time importers (and even some seasoned pros) have experienced painful setbacks due to unverified suppliers or poor factory quality control.
So how do you protect your investment?
It starts with understanding two essential tools in your sourcing toolbox:
✅ Audit pabrik
✅ Quality inspections
These aren’t interchangeable. Each plays a distinct role in de-risking your supply chain. Let’s break it down.
What’s the Difference Between a Quality Audit and a Quality Inspection?
Quality Inspection = Checking the Product
- Conducted during or after production
- Focuses on the physical goods — quantity, appearance, function, packaging
- Detects defects before shipment, saving you from bad Amazon reviews or returns
- Best for order-level assurance — especially for high-value or custom items
Factory Audit = Checking the Manufacturer
- Conducted before placing orders
- Focuses on the factory itself — production capabilities, legal compliance, labor practices
- Verifies whether the factory is real, reliable, and ethical
- Critical for long-term supplier relationships
Importer tip: A quality inspection protects this order. A factory audit protects your entire sourcing strategy.
The 4 Types of Quality Inspection Every Importer Should Know
Inspections aren’t one-size-fits-all. The best sourcing agents use a layered strategy throughout production. Here’s how:
Pre-Production Inspection (PPI)
Checks raw materials and components before manufacturing begins.
- Confirms supplier isn’t cutting corners
- Validates component specs match your brief
- Reduces risk of delays from bad material sourcing
- Key for complex products or first-time orders
During Production Inspection (DUPRO)
Happens when 20–80% of production is complete.
- Identifies defects early so the factory can fix them
- Tracks production pace against your delivery schedule
- Reduces full-batch rejection risk
- Great for tight timelines and repeat orders
Pre-Shipment Inspection (PSI)
Performed when production is 80–100% complete, right before shipment.
- Verifies quantity, labeling, dimensions, and packaging
- Uses AQL sampling to detect defects
- Must-have before final payment and container loading
- Standard procedure for Amazon FBA sellers
Container Loading Check (CLC)
Takes place at the port or warehouse during loading.
- Ensures the right SKUs are loaded
- Prevents damage due to poor palletizing
- Useful for mixed or consolidated shipments
- Peace of mind for high-volume orders
When Do You Need a Factory Audit?
You need a factory audit when you want to know who you’re really dealing with.
This is especially important when you’re:
- Sourcing from a new supplier in China
- Launching a merek pribadi product
- Scaling from small MOQs to large orders
- Tired of middlemen misrepresenting factories
