Tariff Impact on Ecommerce
Definition
The effect of import duties and trade tariffs on ecommerce product costs, particularly the de minimis threshold changes affecting cross-border commerce.
Tariff impact refers to how import duties, trade tariffs, and regulatory changes affect ecommerce product costs and profitability. The 2025–2026 tariff landscape has been particularly volatile, with changes to Section 301 tariffs, de minimis duty thresholds, and country-specific trade policies. The de minimis threshold — the value below which imports are exempt from duties — has been a major focus, with its elimination for certain countries dramatically increasing costs for merchants sourcing from those regions. For ecommerce merchants, tariff changes can shift COGS by 5–25% overnight, making real-time cost synchronization critical for maintaining accurate profit floors.
