E-commerce: Rigorous Cross-Border Taxation and the new rules framework in the country

The enactment of Law 15,071/2024 reorganized the accountability in international sales in Brazil. The text defines companies and e-commerce platforms and forces the anticipation of data for the import declaration.

Definition of suppliers and advance information

The law formally frames who acts as an intermediary.This reduces ambiguities about obligations when the sale is mediated by third parties.

Data essential to the import declaration is sent before the arrival of the consignments, improving screening and predictability.

Responsibility for taxes and composition of cargo

Whoever makes the import declaration assumes responsibility for paying federal and state taxes.This changes flows between operation, tax and logistics of companies.

Purchases above US$ 50 receive reference import tax of 60% and still suffer ICMS, which raises the final price to consumers.

Restitution, tax rates and supervision

The law regulates the refund of import tax when the product returns abroad by return. This increases consumer safety and reduces friction in higher value purchases.

The Minister of Finance may adjust the rate in public cases, such as medicines for personal use. Shipment as and more intense enforcement improves control, but can lengthen deadlines if information is incomplete.

Strategies and adaptation

Marketplaces like AliExpress, Shein, and Shopee use promotions, shipping subsidies, and local hubs to shorten deadlines.

Local platforms, for example Mercado Livre, reinforce inventory and fast delivery to compete on experience and predictability.

Payments, conversion and risk

PIX, installment and BNPL adoption increases conversion, but requires robust anti-fraud and chargeback management systems.

Bureaucracy and compliance

Correct documentation, clear product classification and data aligned with the IRS are essential to avoid retentions and delays.

• Result: the competition changes from the lowest advertised price to the best total cost and predictability.

Conclusion

The passage of Law 15,071/2024 marks a turning point in trade with foreign countries, by consolidating the definition of agents, information anticipation and refund rules.

The scenario now combines two forces: increased demand for international procurement and a more structured regulatory framework, with a focus on transparency and accountability.

The standard reduces ambiguity by defining who is accountable for statements, while shifting the operational burden of compliance and data quality to platforms and companies.

For the consumer, this tends to generate more predictability and protection, although deadlines and costs may vary according to supervision and adherence to requirements.
