Depending on the Pallet, the type of products and on the department store this percentage varies a lot.
For example, typically speaking – a clothes load has very little defective items. Most items would have just been returned to the store and the store would just sell them in bulk very cheap as part of a “Returned” load because they do not wish to repack it, re-tag it, clean it if necessary etc. Underwear and socks loads are usually always brand new since most stores do not allow the return of socks and/or underwear from customers.
Also, some department stores have more elaborate Repair & Service Centers then others. Products from stores which have comprehensive Repair & Service centers tend to have a higher defective rate. Generally speaking electronic items have a higher defective rate – whilst non-electronic items such as toys, cookware, cutlery, accessories, domestics etc. tend to have much lower defective rates (e.g. a set of 50 pcs of cutlery set may be in a return load simply because one of the pcs has broken.)
The generally recognized industry average used when trying to estimate working % is as follows: 65%-75% working, 20% Repairable, remainder scrap/spare parts/throwaway etc. Ofcourse no individual load or pallet will have that exact breakdown, but generally speaking the latter percentages are fairly accurate to describe the average expected condition.
Please note – exact working % of any particular pallet/load is unknown – and all items are always untested.
