The United States represents the single largest e-commerce market in the world, with over $1.1 trillion in annual online spending. For international brands, it is the most attractive expansion opportunity available. But the US market is also intensely competitive, operationally demanding, and easy to get wrong if you enter without a proper strategy. Here is how to do it right.
Understanding the US E-Commerce Landscape
Amazon dominates US e-commerce with approximately 40% of all online retail sales. For most product categories, Amazon is the first and mandatory channel for any brand entering the US market. Walmart Marketplace is growing rapidly and represents a strong secondary channel. Shopify-powered DTC stores are the preferred model for brand-building and margin preservation at scale. A successful US market entry typically begins with Amazon and adds DTC within 6–12 months.
Legal and Regulatory Requirements
Before selling in the US, ensure you understand the regulatory landscape for your product category. FDA regulations apply to food, supplements, and cosmetics. CPSC requirements govern children's products and electronics. FTC rules govern advertising claims and endorsements. The consequences of non-compliance in the US are significantly more severe than in many other markets — legal advice before launch is a worthwhile investment.
- Register your business entity (LLC or Corporation) in the US
- Obtain an EIN (Employer Identification Number) for tax purposes
- Understand sales tax obligations across states (post-South Dakota v. Wayfair)
- Ensure product labeling meets FTC and relevant regulatory body requirements
Logistics and Fulfillment Strategy
Fulfillment from outside the US will result in delivery times that are uncompetitive in a market accustomed to Amazon Prime's 1–2 day delivery standard. Establishing US-based inventory — whether through FBA (Fulfillment by Amazon) or a domestic 3PL — is non-negotiable for market competitiveness. FBA is the easiest starting point and gives you access to Prime badge eligibility immediately.
Marketing and Customer Acquisition in the US
The US consumer is exposed to enormous volumes of digital advertising and has developed sophisticated filters for generic marketing. Brand storytelling, authentic UGC, and strong social proof are more important in the US than in most other markets. Meta advertising and Google Shopping are your primary performance marketing channels. TikTok Shop is growing explosively and represents a significant opportunity for brands in lifestyle, beauty, and wellness categories.
Building US Customer Trust
American consumers are highly review-driven and have high expectations for customer service responsiveness. Building your review base on Amazon aggressively from day one, responding to every customer inquiry within 24 hours, and offering a generous, no-questions-asked return policy are the three most important trust-building investments for a new brand entering the US market.
