Products are categorized according to type, as shown in the list below.  From E001 to E013, the numbering system follows the arrangement shown in the old Product Information Sheets (PIS). However PIS products listed under these categories are no longer valid.  Only PQS pre-qualified products are now recommended for purchase. 

A search in the E001 category, cold rooms and freezer rooms, will lead you to a list of pre-qualified manufacturers that have cold room and freezer room components (as described in the corresponding PQS sheet) that have been validated through the PQS process.  Note that products that are listed as "suspended" or "withdrawn" are not recommended for UN purchase.
