Pre-shipment inspection without flying to China

The most expensive defect is the one you discover after the container reaches Lagos. By then you have paid in full, paid freight, paid duty, and you are holding goods you cannot sell. A pre-shipment inspection catches the problem while you still have leverage, before the balance is released and before the goods leave China, and you do not need to be in the room to do it.

What a pre-shipment inspection is

A pre-shipment inspection, or PSI, is a check of your finished goods at the supplier's premises before shipping, carried out by an independent inspector you hire. They go to the factory, pull a sample from the actual production run, and check it against your agreed specification: dimensions, function, finish, labelling, packaging, and quantity.

You receive a report with photographs and a clear pass or fail. Because it happens before the balance payment, a fail gives you room to require rework or to walk away.

Why a third-party inspector, not the supplier

The supplier will always tell you the goods are perfect. That is not dishonesty so much as optimism and self-interest. An independent inspector has no stake in the order shipping, so their report reflects what is actually in the cartons.

Several established inspection companies operate across China and will send an inspector to almost any factory for a fixed day rate. For a typical order, that fee is small against the cost of a bad shipment.

Set the inspection up to succeed

An inspection is only as good as the brief you give it:

1. Provide a clear specification. Photographs of your approved sample, measurements, materials, colour references, packaging requirements, and labelling. The inspector checks against your brief, so vague briefs get vague results.
2. Define what a defect is. Distinguish critical defects, the ones that make a product unsellable or unsafe, from minor cosmetic issues. This feeds the AQL sampling, which we cover in AQL sampling explained.
3. Time it right. Book the inspection when production is essentially complete and packed, not half done.
4. Tell the supplier in advance. A reputable supplier expects inspections and cooperates. Resistance to an inspection is itself a warning sign.

Tie the inspection to your payment terms

The leverage only exists if your payment terms preserve it. The common structure is a deposit up front and the balance before shipping. Schedule the inspection before that balance is due, and make your agreement explicit that the balance follows a passing inspection. This single alignment, inspection before balance, is what turns QC from a hope into a control.

Quality control is not a cost. It is the small price you pay to keep your real money attached to goods you can actually sell.

When the report comes back

• Pass: release the balance and let the goods ship.
• Minor issues: decide whether to accept, negotiate a discount, or require rework, depending on severity.
• Fail on critical defects: require rework and re-inspection before any further payment. Do not let goods ship "and we will sort it out later". You will not.

Where settlement fits

Your deposit and your balance are both RMB payments to the supplier. With a trade-facilitation service, each is a separate request with its own locked rate and receipt, which also gives you a clean record of deposit versus balance for your files.

So structure the deal as deposit, inspection, then balance. When each payment is due you can make a request to settle it on Alipay from Naira. The inspection is what makes sure the balance you release is buying goods you approved, not a surprise you cannot return.
