Brazil is actively migrating import operations from legacy DI/LI flows into the Portal Único / Duimp environment. The exact path depends on the operation and current migration schedule. Build the shipment around the current official flow, the applicable administrative treatment and the qualified professionals filing the declaration—not around an outdated process map.
Start customs work before the cargo arrives
Close importer structure, habilitation, NCM, product catalogue/attributes, licensing, commercial documents and transport instructions before arrival. Customs clearance is the validation stage, not where the import strategy should be invented.
Check whether the operation is in Duimp or a legacy flow
Siscomex is enabling operations in stages. As of 14 September 2026, the official schedule still describes a phased activation for remaining cases. Verify the exact eligible flow on the shipment date.
Treat LPCO and regulator controls as critical-path items
Some controls can be required before shipment. Use the official treatment simulator and current notices to identify whether an agency action, license, permit, certificate or other document is needed.
Use a customs broker for filing expertise, but keep business ownership explicit
A registered despachante can represent the importer in customs acts when accredited. HQ/local management should still own commercial decisions, evidence, deadlines and exceptions instead of outsourcing every decision to the broker.
Brazilian customs, tax and product-control rules are transaction-specific and change over time. E2M research is decision support and local coordination—not customs brokerage, legal, tax or product-regulatory advice. Confirm shipment-specific NCM, licensing, tax treatment, declarations and regulatory requirements with the qualified customs, tax, legal and product specialists responsible for the operation.
