For more than a decade there has been a persistent issue of ships incurring customs fines at Argentina’s ports. The Argentine Customs Authorities are known for meticulously scrutinising every detail of ships’ declarations and stores lists, imposing strict penalties for any discrepancies identified, as permitted under its Customs Code. While the frequency of such fines has varied over the years, our correspondent Sigvart G.J. Simonsen & Cia. S.R.L reports that customs-related fines remain common and reminds ships’ Masters and Officers to be particularly attentive when completing all required port documentation.
As cited in our insight: “Argentina - determining the cargo quantity for bulk cargoes - are shore figures mandatory?”, issues related to the determination of cargo quantity for bulk cargoes have long been a challenge in Argentina. It is worth noting that both shortages and overage in solid bulk cargoes can trigger customs issues at Argentine ports, a situation frequently encountered in fertilizer imports. According to General Resolution 4138-E/2017 on the determination cargo quantities, the tolerance margin for customs fines is 4% and if a discrepancy exceeds this threshold, a fine of up to 5 times the CIF value of the cargo may be imposed. For additional details and recommendations, please refer to Circular 058/2025 “Custom claims on discharges of bulk solids in Argentina” by Pandi Liquidadores S.R.L.
On 10 October 2018, Argentina’s Customs Authorities issued General Resolution 4317/2018 in an effort to improve uniformity in the application of customs regulations in the country. The Resolution approved the following set of forms to be used by vessels declaring any stores on board upon arrival at an Argentine port:
Although these forms provide some uniformity, there are items in the lists which may still be unclear. One example is in form OM 1645 (Ship’s store declaration), where the form refers to “Lube oil”. However, it does not clarify if quantities of lube oil in the sump tank should be declared or not or if the volume of lube oil should be measured with the engines running or not.
Ship operators should continue to remind Masters of ships calling Argentine ports to exercise particular vigilance when completing customs declarations and stores lists, also when using the forms from 2018. Masters are also advised to contact their local agent in writing well in advance of arrival to confirm the customs and immigration regulations in effect at that time, as well as the documentation and details required.
The "Guidance for Masters - Key Points when Declaring Store Lists Before the Argentinian Customs House" by Simonsen provides a summary of its recommendations on how to avoid fines when calling at Argentine ports. The guidance provides helpful advice based on the correspondent’s extensive case experience and we recommend that ship operators forward a copy of this to all ships likely to call at Argentine ports. Furthermore, while the guidance stresses the importance of declaring accurate figures for all consumables onboard, including avoiding duplication of items, it advises Masters and officers to be particularly attentive when declaring goods such as:
paints, thinners, and other chemicals
bunkers and other “oils in use”, such as main engine sump tanks, lube oil and hydraulic oil
electronic appliances, including crews’ personal effects
tobacco and alcohol
spare parts, including engine and deck inventories
In case of any doubt, e.g. if requested to sign an unfamiliar document or language and cultural differences make communication difficult, ask for the agent’s and/or the P&I correspondent's assistance.
Furthermore, if Masters should encounter irregularities in the form of customs officers soliciting bribes to overlook discrepancies, we strongly recommend reporting this via the Maritime Anti-Corruption Network’s (MACN) anonymous incident reporting system.
