An ONIX code which specifies that the product is free of charge, or a reason why a price amount or price code is not sent. If code value 02 is used to send advance information without giving a price, the price must be confirmed as soon as possible. Optional and non-repeating, but required if the <Price> composite does not carry a price amount or price code.

Use here in preference to P.26.42 when the product is available under a variety of priced and unpriced terms from the same supplier.
