The document outlines a 3-step process for quality inspection sampling: 1) Select cartons randomly from the shipment ensuring a sufficient sample size based on quantity and assortment; 2) Randomly select cartons from different areas of the pallet; and 3) Randomly select products from different layers and bags within the cartons to represent product quality. The goal is to select samples proportionally and randomly from both packed and unpacked products to accurately assess real product quality.

1. Quality inspection Sampling
Standard

2. • After deciding the sample size based on inspection standard and
AQL tables, here we need to choose the number of products to
check.
1. Select the right quantity of cartons
At least the square root of the total number of cartons(Example: at
least 8 cartons if there is a total of 63 cartons.), or otherwise defined
by client, in the shipment are randomly selected and opened. The
inner content is checked for correct quantity and assortment. The
samples are selected proportionally from the opened cartons. If the
sum of opened cartons can not give the sufficient number of sample
size, cartons should be opened until the quantity is met.
2. Randomly select the cartons from the pallets
Select the cartons randomly, for example, from the front and back,
top and down, right, let and inside of the pallet, not just from the
same position of the pallet.

3. If the goods are not 100% packed, also need to select some
samples from the unpacked products according to the ratio of
packed and unpacked pieces.
For example, if there are 200 pcs among 4000 to be inspected, and
there are just 3000pcs packed into cartons, and 1000pcs ready to
be packed, have to select 150 pieces from packed cartons and 50
unpacked pieces.
3. Randomly select the products from selected cartons
During the selection of products from cartons, need to randomly
pick up the pieces, for example, from each layer or each poly bag of
product, to represent the real product quality situation as maximum
as possible.
