  • US CBP enforcement of accuracy of data on importer of record could result in immediate voiding of IOR numbers
    In a general notice published 9 August 2026, the US Customs and Border Protection (CBP) announced that it is implementing enhanced enforcement procedures to verify the accuracy of the information used to identify and validate importers of record (IORs) on Form 5106, Create/Update Importer Identity Form. Effective 18 September 2026, CBP will void the IOR number of any importer, or customs broker acting on the importer's behalf, that has failed to provide complete and accurate information on Form 5106. A voided IOR number is invalid for any purpose, including entering merchandise into the United States. CBP has indicated it may also pursue other enforcement actions as appropriate.
  • Argentina’s "Super RIGI" bill would create enhanced incentives regime for large-scale investments in new industries
    Argentina's Chamber of Deputies recently approved a bill that would establish the "Régimen de Incentivo para Grandes Inversiones en Nuevas Industrias" (Super RIGI) regime, which is aimed at encouraging large-scale investments in new industries. The bill would establish significant tax, customs, foreign exchange and social security incentives, including a 15% corporate income tax rate, accelerated depreciation, indefinite loss carryforward, reduced dividend withholding after the fourth year, value-added tax relief via tax credit certificates, and the ability to benefit from a 30-year tax stability (i.e., taxpayer's income tax rate will not be increased for 30 years).
