Jean-Sebastien Binette

Founder of USTariffCalc.com, a suite of free tariff calculators used by importers, Amazon FBA sellers, and e-commerce entrepreneurs to navigate the 2026 US tariff landscape. I track and analyze the impact of Section 301, Section 122, IEEPA duties, and de minimis threshold changes on cross-border commerce. My work includes hands-on tariff impact analysis on real products sourced from Alibaba, landed cost modeling across China, Vietnam, and Mexico supply chains, and profit margin calculations for FBA sellers operating under the current multi-layered tariff structure. I publish data-driven guides on how US trade policy affects small businesses and consumers ordering from platforms like Temu, Shein, and AliExpress.
