Argentina has not ratified Annex VI of the International Convention for the Prevention of Pollution from Ships and there is no domestic legislation concerning the use of exhaust gas cleaning systems. As a result, there is no prohibition on the use of open-loop scrubbers in territorial seas or internal waterways (eg, when manoeuvring inbound or outbound on the Paraná River or when a vessel is idling or carrying out a loading or discharging operation at a port).
Further to a National Cabinet meeting on 16 March 2020, a new regulation was introduced which prohibits entry into Argentina by sea, air or land for 15 calendar days by non-resident foreign nationals; this timeframe may be extended or lifted by the government as deemed appropriate. Given the uncertainty about the duration of these measures, it remains to be seen what effect they will have on the maritime industry.
The question of whether foreign-flagged ships involved in international trade are subject to value added tax (VAT) when supplying bunkers in Argentina is frequently posed. If a vessel is supplied bunkers in one Argentine port and subsequently calls to another Argentine port before proceeding overseas, this is generally considered to be cabotage and is therefore subject to VAT.
Local authorities have increasingly exercised their power to enforce local regulations concerning waste disposal and broadened the responsibility of vessels in this regard. It has become common practice for local authorities to request the compulsory discharge of waste from vessels, even if this action appears to go against commonly accepted international law that is binding in Argentina.
Ships calling at ports on the Parana river are increasingly being asked to submit a pest control certificate to the Health Authority. Failure to comply with this request could require the ship to be fumigated. However, this can be avoided if a ship can prove that it has been fumigated by a competent authority or if it has been exempted from such operation in the past six months and obtained a certificate from the health authorities of a port officially authorised for this purpose.
