Article 14 classifies infractions as minor, serious and very serious and provides for four types of penalty: warning, fine, suspension and cancellation. Very serious ones are penalized with cancellation, suspension or fines between 1.000 and 4.000 UVT, or between 70% and 100% of the FOB value or of the goods, or 100% of freight, VAT or taxes as the case may be; serious ones, with fines between 200 and 999 UVT, between 10% and 69% of taxes, freight or FOB value, or other bases the rule specifies; and minor ones, with a warning or fines between 50 and 199 UVT or between 1% and 9% of the corresponding base. Article 15 lists the conduct by type of user (declarants, customs agencies, free zones, warehouses, among others). Some examples: using irregular means or simulating foreign-trade operations (very serious, art. 15.1.1), not having the supporting documents required by Decree 1165 of 2019 (serious, art. 15.2.2.2) or preventing or obstructing control activities without just cause (minor, art. 15.1.3.1).
