Amazon, Magalu, Shein, TikTok Shop, and other channels: fees, rules, and when it makes sense to join.
With Amazon Sponsored Products, you pay per click, and your ACOS needs to stay below your margin. For a R$ 69,90 product using DBA, the ACOS limit is 28.6%, or a ROAS of 3.5. See the math, how automatic campaigns work, and the step-by-step guide.
Amazon’s Buy Box, called the Featured Offer, goes to the seller with the right mix of total price, fast delivery, stock, and a healthy account. See what matters, how a R$ 69,90 product loses 41% of its profit after a R$ 10 price cut, and how to find your minimum price.
Amazon requires a GTIN, such as a 13-digit EAN, in most categories. If you don’t have a code, you can request an exemption: approval is automatic for generic products and takes up to 48 hours for your own brand. Learn when each option applies, how to request one, and which mistakes can block your listing.
To reinstate a suspended Amazon seller account, submit an appeal and an action plan that covers the root cause, immediate steps, and preventive measures. See the metrics that can get your account suspended (ODR below 1%, late shipments below 4%), what to write, and what not to do.
With DBA (Delivery by Amazon), you pack the order and print the label, then Amazon picks it up at your address or you drop it off at a location. Fees range from R$ 4,50 per unit for items under R$ 30 to R$ 13,45 for a 600 g item priced at R$ 89,90. See the steps and rules.
In Amazon FBA Brazil, fulfillment fees range from R$ 5,65 to R$ 6,05 per unit for products under R$ 79, and from R$ 10,05 to R$ 51,35 above that, depending on weight. Add a 10% to 15% commission and storage fees per cubic meter. See the math and when it pays off.
With a 12% commission on both channels, Amazon with DBA leaves you R$ 0,35 to R$ 3,65 more per sale than Mercado Livre’s Classic plan across six products priced from R$ 24,90 to R$ 179,90 (October 2026). See the table, where the numbers flip, and how to decide based on monthly profit.
In Brazil, sellers get the Amazon Prime badge through FBA (stock stored at a fulfillment center) or the restricted FBA Onsite program. DBA and seller-fulfilled shipping don’t qualify for Prime. See the requirements, storage fees, and when the badge is worth it.
Amazon Brand Registry is free, but you need a registered trademark or a pending application with INPI, which costs R$ 440 per class for MEI, ME, and EPP businesses as of 12/20/2025. See the requirements, the step-by-step process, and when the program is worth it for sellers with their own brand.
Amazon measures account health using three metrics: orders with issues below 1%, late shipments below 4%, and cancellations before shipment below 2.5%. Out of 500 orders, that means no more than 4, 19, and 12, respectively. See how each metric works and how to keep your account healthy.
Selling books on Amazon costs a 15% commission plus the DBA shipping fee, from R$ 4,50 to R$ 6,75 for orders up to R$ 78,99. Learn about category approval, ISBNs, the numbers for three new and used books, and when the Professional plan is worth it.
Amazon charges a 10% to 15% commission by category, plus R$ 2 per item on the Individual plan or R$ 19 per month on the Professional plan (free for the 1st year). See the fee table, DBA and FBA fees, and a comparison of costs for three products on Amazon, Mercado Livre, and Shopee.
On Amazon Brazil, the Individual plan charges R$ 2 per item sold, while the Professional plan costs R$ 19 per month and is free for the 1st year for new sellers. At 10 or more sales per month, the Professional plan costs less. See commissions of 10% to 15%, FBA, DBA, and the numbers for two products.
