Brazil closes the remaining DI and electronic DSI routes on 10 December
Nov 2, 2026 · 5 min read

In short
The Siscomex schedule updated on 29 October 2026 says that all operations still available in the legacy Siscomex Importação system, including Declaração de Importação (DI) and electronic Declaração Simplificada de Importação (DSI), are due to be switched off on 10 December across maritime, air, road and rail modes. A separate 1 December wave covers three named groups, while Siscomex Internação remains scheduled for 27 March 2027. Earlier administrative licences and a few transition cases follow special rules. The dates remain conditional on validation and may be revised if blocking system errors appear, so each Brazilian importer should check the live schedule and official simulator for the exact operation.
Brazil has put a clear end date on the remaining legacy import declarations. The official schedule updated on 29 October states that every operation still open in Siscomex Importação, including DI and electronic DSI, is scheduled to close on 10 December 2026 for maritime, air, road and rail imports. From that point, the applicable Portal Único route and Duimp replace the old filing route. This is broader than the earlier cut-offs for individual products, packaging types or transport modes.
The final migration is staged. A 1 December wave covers Radar Limitado, the ZFM, ALC and AOC operations, and all Suframa-controlled products, subject to the transition cases shown in the official table. The 10 December line then captures all operations that remain in Siscomex Importação, including electronic DSI. Siscomex Internação is listed separately for 27 March 2027. The government also says future dates depend on private-sector validation and can be revised if a blocking system problem is identified, so the published schedule should be checked again before shipment and filing.
A cut-off does not erase every earlier licence. Where an LI with administrative control was registered before the relevant shutdown date, the schedule allows it to be linked to a DI after that date; a replacement LI for an approved licence can also still be issued. Where several authorising bodies or tax regimes apply, the DI closes only when the relevant route has closed for all of them. By contrast, an LI registered after the cut-off does not preserve the old channel: an attempted DI should return a message that Duimp is mandatory. Receita Federal also warns that a DI filed for an operation already mandatory in Duimp is subject to cancellation by customs.
The practical test belongs to the Brazilian importer and customs broker, but the European supplier controls much of the source data. For one representative shipment, run the official DI-shutdown simulator and confirm the importer, operator and product records, NCM classification and attributes, tax treatment, any LPCO, cargo references and the hand-off between ERP, broker and Portal Único. Reconcile those fields with the commercial invoice, packing information and technical product file. A successful login or an old LI template is not evidence that the full Duimp flow works.
Treat 10 December as a systems and data deadline, not merely a customs-calendar date. Ask the importer to document the applicable result from the live schedule, complete a controlled Duimp test and name the owner of each correction before the next shipment departs. Monitor Siscomex notices for a revised date, but do not build the plan around a postponement. If the product, licensing path or local importer structure is still unclear, an Opportunity Scan can map the EU-to-Brazil route and show which data and approvals need to be ready before the legacy channel closes.
