Trump starts trade probes on Mexico, China as tariff fight intensifies
The White House launched trade investigations into 16 trading partners including Mexico and China as of March 2026, signaling new tariff rounds are imminent. Sellers sourcing from these countries face potential cost increases across electronics, apparel, home goods, and general merchandise categories.
The non-obvious hit: tariff probes take 6-12 months to resolve, but suppliers raise prices in anticipation — meaning COGS creep starts before any official tariff. Pull your top-50 ASINs by COGS origin now and identify which are China/Mexico-sourced before quotes change.
This accelerates the ongoing margin compression cycle for marketplace sellers — a second tariff wave compounds existing fee increases from Amazon and Walmart, squeezing sellers caught between fixed ad costs and rising landed costs.
Run a supplier origin audit in your inventory management system — flag any SKUs sourced from China or Mexico and model a 10-25% landed cost increase to stress-test margin floors.
In the next 30 days, lock in POs at current pricing with suppliers and explore nearshoring or Vietnam/India alternates for high-velocity SKUs before quote revisions hit.
Bottom Line
New tariff probes on China and Mexico mean imminent COGS increases for most marketplace sellers.
