Amazon FBA Inspection: When to Book PSI or DPI

FBA sellers feel quality problems twice: first as inbound placement fees and prep delays, then as reviews and returns if bad units slip through. Independent inspection in Asia—before you wire the balance—is the most cost-effective brake on both. Here is how CloudSpects clients typically time PSI and DPI around FBA reality.

Default rule: PSI before final payment

Align pre-shipment inspection with your milestone so that a clear English report lands before you release most of the contract value. For many FBA purchase orders, that means PSI after packing is substantially complete but before the factory moves goods to the forwarder’s warehouse.

When to add DPI mid-production

• New supplier or first production run of a complex SKU.
• High return-risk categories (electronics, textiles with strict sizing, children’s products).
• Large MOQ where late discovery of a systemic defect would scrap thousands of units.

DPI catches line-level issues while rework is still economical; follow with PSI on the finished, packed lot. See also our comparison: PSI vs DPI.

FBA-specific checklist items

• FNSKU and outer carton label match (mix-ups are expensive).
• Poly-bag suffocation warnings and bundle integrity where Amazon requires them.
• Carton weight and dimensions vs. what you filed for shipping plans—surprises here create split shipments and unexpected DIM weight.
• Battery / hazardous materials documentation if your listing requires it.
