The minimum number of copies which must be ordered to obtain the price carried in an occurrence of the <Price> composite. Optional and non-repeating. If the field is present, the price is a quantity price (and only whole multiples of the qualifying quantity may be ordered at that price). If the field is omitted, the price applies to a single unit.

Note the similarity between <MinimumOrderQuantity> and <OrderQuantityMinimum> in P.26.41b: only <MinimumOrderQuantity> has an effect on the specification of <Price>. Use of <MinimumOrderQuantity> is close in effect to a multi-item trade pack (see <ProductComposition>).
