2026 will be the ”window of opportunity for Chinese sellers” in the Latin American e-commerce market, but it is no longer the ”golden age” when sellers could simply set up shop and start selling. Meike Duo’s Q2 2026 GMV was $21.9 billion (+44%), with 89 million active buyers and cross-border business up +68%. However, during the same period, Brazil’s dual CBS/IBS VAT system took effect on August 1, and Mexico’s RFC entity consistency verification began in June. As a result, compliance costs for Chinese sellers in Latin America are expected to rise by 20%–30% for the full year of 2026. For newcomers entering the Latin American market in 2026,The correct path is: Start with a cross-border store (Mexico) → Get the store up and running within 3–6 months → Apply for an RFC tax ID → Upgrade to a local store → Expand into multiple countries. Skipping any step can easily lead to problems.
