The valuation indicators should be declared considering the contractual conditions of the transaction.
The valuation indicator code comprises four digits, each of which being either a '0' or a '1'. Each '1' or '0' digit reflects whether or not a valuation indicator is relevant to the valuation of the goods concerned.
1st digit: Party relationship, whether there is price influence or not
2nd digit: Restrictions as to the disposal or use of the goods by the buyer in accordance with Article 70(3)(a) of the Code.
