Quantity check confirms whether the actual goods on site match the declared shipment quantity. It is a basic but essential part of quality inspection, because before checking workmanship, defects, or function, buyers first need to know whether the correct quantity is really available.
This check is not only about counting pieces. It also covers packed quantity, carton quantity, quantity per carton, and the breakdown by size, color, model, or specification. It helps buyers confirm whether the goods match the purchase order, packing list, and shipment information.

What Inspectors Check
Inspectors compare the declared quantity with the actual goods available at the factory.
Total finished quantity
Inspectors verify how many finished products are actually completed on site. This helps confirm the real production status at the time of inspection.
Packed quantity ready for shipment
They also check how many goods are already packed and ready for shipment. This is especially important in Pre-Shipment Inspection, because sampling should be based on completed and packed goods.
Carton count and quantity per carton
Inspectors check the number of export cartons and the quantity packed in each carton. Wrong carton count or wrong quantity per carton may affect shipment accuracy and warehouse handling.
Assortment ratio
For mixed orders, inspectors verify whether the size, color, model, or specification ratio matches the order requirements. This helps identify packing mistakes and shipment imbalance.
Unfinished or unpacked goods
Inspectors also confirm whether unfinished or unpacked products are being included in the declared quantity. This is important because such goods should not normally be treated as ready shipment quantity.
Why It Matters
Quantity problems can directly affect shipment schedules, delivery commitments, and payment decisions. If the declared quantity is inaccurate, the inspection result may not reflect the real shipment status.
Quantity also affects AQL inspection. If the lot size is wrong, the sample size based on AQL sampling may also be unreliable. That is why quantity check is one of the first steps in Initial Production Check, During Production Inspection, and especially Pre-Shipment Inspection.
Common Problems Found
Common issues include actual quantity lower than declared, incorrect carton count, wrong quantity per carton, mixed sizes or colors in cartons, and mismatches between actual goods and the packing list.
These problems may cause shipment delays, loading errors, warehouse confusion, or customer complaints. In some cases, the product quality may be acceptable, but the shipment still cannot proceed smoothly because the quantity information is inaccurate.
Conclusion
Quantity check is a simple but important step in product inspection. It helps buyers confirm the true shipment status, supports correct sampling, and reduces avoidable shipment and delivery problems.
When combined with other checks on NBNQC, it gives buyers a clearer view of overall order readiness and shipment quality.
