Amazon on Thursday tried to temper investor concerns about the impact of the Trump administration's tariffs on its e-commerce business, but the company may have few options left to ensure small third-party sellers stay put in the face of crushing levies.

U.S. President Trump has imposed 145% duties on imports from China, a move that has left companies including Amazon, Walmart and Apple scrambling to reassess supply chains and find ways to keep costs down.

The tech giant reported revenue grew by 9% during its first quarter to $155.7 billion. Its profit was $17.1 billion. The figures topped Wall Street projections.

Amazon recently considered listing tariff fees to its advertised prices on the Amazon Haul app, but a phone call with President Trump changed those plans.
