The Plenary of the Brazilian Supreme Federal Court (STF) established the understanding that the levy of Import Tax (II) on goods of national origin that, after a definitive export, return to Brazilian territory is constitutional.
The decision was rendered in a virtual session concluded on March 20, 2026, in the judgment of an action filed in 2016 by the Office of the Prosecutor General, which challenged regulatory provisions equating such goods to foreign products for tax purposes.
Thesis Established by the STF
The Court consolidated the following understanding:
- A definitive export breaks the legal connection between the goods and the domestic market;
- The subsequent return to Brazil constitutes a new entry into the customs territory, triggering the taxable event of the Import Tax;
- The national origin of the goods does not prevent taxation, as the relevant criterion is their foreign provenance at the time of entry into the country.
Grounds of the Prevailing Opinion
The opinion of the reporting justice, Justice Kassio Nunes Marques, prevailed and was followed by the majority of the Plenary.
According to the reporting justice:
- The National Tax Code (CTN) adopts, as the material criterion of the Import Tax, the entry of goods into the customs territory destined for the domestic market;
- The Federal Constitution links the incidence of the tax to the foreign provenance of the goods, rather than their production origin;
- The analysis must prioritize the economic substance of the transaction, rather than formal aspects related to the origin of the product.
In this regard, the Court emphasized that the reentry of the goods constitutes a new and autonomous economic transaction, subject to the legal regime applicable to imports.
Distinction from Temporary Export
The STF also distinguished the case at hand from a previous precedent (RE 104,306), in which the Court excluded the incidence of Import Tax in cases of temporary export, such as goods sent abroad for exhibitions or trade fairs.
In such cases:
- There is no rupture of the link with the domestic market;
- The reentry of the goods does not constitute a new economic transaction;
- Subsequent legislation expressly excluded taxation in these situations.
In contrast, in cases of definitive export, there is an effective economic removal of the goods from the domestic market, justifying taxation upon their return.
Economic and Competitive Rationale
The STF also grounded its decision on tax policy and competitive considerations, noting that the absence of taxation could:
- Encourage abusive tax planning structures;
- Generate competitive distortions;
- Weaken customs control mechanisms;
- Undermine the principles of equality and free competition.
Practical Impacts for Taxpayers
The decision carries significant practical implications:
- Exporting companies must carefully assess transactions involving potential reentry of goods into Brazil;
- Structures involving export followed by reimportation may result in additional tax burdens;
- It reinforces the need for a clear distinction between temporary and definitive exports in operational and tax planning;
- The understanding is likely to impact international supply chains, particularly in repurchase, return, or reentry operations.
Conclusion
The STF consolidates an important guideline by prioritizing the economic reality of cross-border circulation of goods, rejecting a purely formal approach based on the product’s national origin.
The decision reinforces the principle that the Import Tax applies to the entry of goods into national territory, regardless of their production origin, provided that a new insertion into the domestic market occurs after a definitive export.
