Perfect sample, bad bulk order: how to stop it with AQL inspection

“The sample was perfect. The bulk was not.” It is one of the oldest problems in sourcing. A sourcing platform lists quality slipping from approved samples to bulk among the common buyer problems in Bangladesh. There are two practical fixes, and both must be in place before the goods leave the factory.

Why can the bulk order differ from the sample?

Samples are often made in a special sample room by the factory’s best workers. Bulk is made on the main production floor. Sometimes it is made in another factory you never saw. This is called subcontracting. Check 5 in our guide to checking a factory before a deposit covers it.

Hidden subcontracting is an old and serious risk. After the deadly Tazreen factory fire in 2012, two large US retailers said their suppliers had moved work there without permission.

Cost pressure in 2026 makes shortcuts more tempting. Diesel prices in Bangladesh rose 17.4% in September 2026, and exporters say they cannot pass these costs on to buyers. In our view, that squeeze raises the risk that a factory quietly cuts quality or moves work elsewhere.

Fix 1: a pre-shipment inspection using AQL

A pre-shipment inspection is an independent check of finished goods before they are shipped. Inspectors usually use AQL (Acceptable Quality Limit) sampling, based on the ISO 2859 standard. The inspector checks a set number of random pieces. The order passes only if defects stay at or below a fixed limit.

Here is a worked example from QIMA, for 4,000 pieces at the common AQL 2.5 level (General Inspection Level II):

1. The inspector picks 200 pieces at random.
2. If 10 or fewer have defects, the order passes.
3. If 11 or more have defects, the order fails.

The AQL level you choose decides how strict the check is (QIMA):

Defect type or product	Usual AQL
Critical defects (unsafe or unusable)	0, none allowed
Higher-risk items	1.0
General consumer goods (the most common level)	2.5
Products where small cosmetic flaws are acceptable	4.0

In Bangladesh, V-Trust publishes $268 per inspector-day in the manufacturing areas it highlights and $298 elsewhere, all-inclusive, with reports within 24 hours (October 2026). QIMA promises an inspection anywhere in Bangladesh within 48 hours but does not publish a day rate.

Write the AQL level, your list of defects and the approved sample into the contract. Then “pass” means the same thing to you, the factory and the inspector.

Fix 2: no pass, no final payment

An inspection only works if a failed result has consequences. So make the final payment depend on a passed inspection report.

• Deposit and balance: pay the balance only after you receive a passed report.
• Letter of credit (LC): a bank’s promise to pay the factory once it presents the correct documents. You can list a named inspector’s pass certificate as one of those documents.

This matters even more in Bangladesh. Under Bangladesh Bank’s 30 July 2026 export circular, discounts that buyers claim after shipment on garments, jute goods and leather goods must go to a central bank committee for approval. In practice, a quick credit note for faulty goods is hard to get once the ship has left.

Is an inspection worth it on a small order?

Here is the honest trade-off. One inspection of about $300 is 10% of a $3,000 order. That is a real cost for a small brand. In our 300-hoodie example, one inspector-day adds about $1 a hoodie. And AQL checks a sample, not every piece. An order of 4,000 can pass with up to 10 faulty pieces in the 200 checked, so some faulty pieces can still reach you.

Set that cost against what a failed shipment would cost you: returns, refunds, replacement stock and a lost season. For a first order with a new factory, our view is that one final inspection is the minimum. A second visit during production, at roughly double the cost, is worth considering, because it catches problems while they can still be fixed.

What this means for your order

Before you pay a deposit, put four things in the contract: the signed approved sample as the standard, the AQL level that defines a pass, no subcontracting without your written consent, and final payment only after a passed inspection. Book the inspection date when you confirm the order, not when the goods are packed. Loom & Harvest does pre-shipment inspections, sample coordination and factory checks for fixed fees, and you can send an enquiry with your product and quantity.
