Carriers have unique oversize codes.  Possible value include (but are not limited to):

• NONE
• DimWt (Package qualified by carrier to use dimensional weight for ship rate)
• Large Pkg

For some carriers, discounted "Shipment" pricing may be calculated in some circumstances in which multiple boxes are considered as a single box for the rate calculation. In these cases, this field will contain the designation "combined" (indicating the rate for the single "package the carrier has constructed for rating), or "subset" (indicating the other actual packages that the carrier does not individually rate).
