If a product inspection or a laboratory test is failed, the supplier will get in contact with the buyer within 24 hours with a detailed explanation. If shipment is delayed because of unacceptable quality, the supplier will bear all consequences for this delay.
If a product inspection is refused, the buyer has the right to ask for a re-inspection, the cost of which will be re-invoiced to B in full. And so on until the inspection accepted by the buyer.
If some products are found defective and/or not conform to product specifications, the supplier will check the whole quantity and will sort them out of bulk quantity. If re-production is impossible, the supplier should let A know immediately about it.
If the inspection is failed (and refused by the buyer) twice in a row, the buyer reserves the right to ask B to pay for a third-party inspection firm (appointed by the buyer in written), which will do a 100% check on the shipment.
If a lab test is failed, the supplier will have to pay for additional tests from the same laboratory.
