The postal traffic and express shipments modality (Arts. 253 and 254 of Decree 1165 of 2019) covers correspondence, shipments through the official postal network and express or courier shipments. To use it, the shipment must meet the regime's requirements: an FOB value not exceeding USD 2,000, a maximum weight of 50 kg, no legal or administrative import restrictions (except non-commercial shipments of up to 6 units of the same class), no goods prohibited by the Universal Postal Union, and compliance with the postal size limits set out in number 6. As to taxes, Article 261 and its paragraph (Decree 1090 of 2020) provide that, as a rule, customs taxes are assessed; if the FOB value is up to USD 200, excluding delivery charges, no customs duty is paid. Correspondence, for its part, pays no customs duty.
VAT is a separate question from customs duty. Under Article 428 paragraph j of the Tax Code (Estatuto Tributario; Law 2277 of 2022, Art. 73), the VAT exclusion for postal, courier or express shipments of up to USD 200 applies only when the applicable free trade agreement expressly obliges non-collection and the import has no commercial purpose; DIAN has publicly indicated the US free trade agreement as the current typical case, without stating that it is the only possible one. When VAT is due, the general rate is 19%. Above USD 200 FOB taxes are assessed and, according to DIAN's public page, a 10% duty is often applied under tariff headings 9807.10 or 9807.20 if the specific tariff heading is not declared, always subject to the heading and the rules in force. If the shipment fails the requirements of Article 254, intermediaries must report it to DIAN and the goods go to a bonded warehouse, where they must change modality (Art. 258), normally to ordinary import. Seizure is a different mechanism with its own grounds, covered on the seizure and forfeiture page.
