A critical defect is a fault that could injure the user or breaks a mandatory safety or legal rule for the destination market. Buyers usually set its AQL at zero: accept 0, reject 1. One critical defect in the sample fails the whole lot, whatever the major and minor counts show.

Critical defects by product
Product
Typical critical defects
Furniture
Unit tips over in a stability check; protruding nail, staple or screw tip; broken weld on a load-bearing frame
Toys
Small part that detaches; sharp edge or point; loose eyes on a soft toy
Electrical goods and lamps
Live part that can be touched; wrong plug for the market; missing earth on a metal body
Kitchenware
Glass shard or chip in a food-contact item; coating peeling into food
Any goods
Mould; a broken needle in textiles; a mandatory warning or marking missing
The rule behind the class comes from the market. For example, the STURDY Act sets stability and warning rules for clothing storage furniture sold in the US, and EN 71 covers toy safety in the EU.
From our inspections
Real photos from our published sample reports, anonymised. Click a source to read the full report.
In our Sample 05 report, a five-drawer cabinet in mango wood and iron tipped forward when all its drawers were opened, and it had no provision for an anti-tip kit. That one unit was enough. The lot of 465 pieces was Not cleared on the critical finding alone, before the major count was even considered. The fix needed an anti-tip kit or a design change, not a touch-up.
How Clear To Load treats critical defects
Any critical defect gives a Not cleared verdict. The inspector photographs it, notes how it was found, and checks whether the cause is likely to repeat across the lot. Setting the faulty unit aside does not change the verdict, because the same fault may sit in units outside the sample. Your defect list should name the critical defects for your product before the visit, so there is no argument about class on the day. A tip-over test or similar safety check is added to the checklist where the product calls for one.
Can a critical defect be accepted with a discount?
It should not be. A critical defect is a safety or legal risk, and selling it can lead to recalls or liability. The usual route is rework of the whole lot, then a reinspection.
Who decides whether a defect is critical or major?
You do, through your defect list and the market rules. Write borderline cases into the list before the inspection, for example whether a sharp edge on a hidden underside counts as critical.
Does a critical defect always mean a lab test failed?
No. Most critical defects are found by eye or by hand on site. Lab tests such as flammability or chemical limits are reported separately.
