✅ Why These Markets Should Matter to Amazon Sellers
High Demand + Volume
Selling in the U.S. gives you access to Amazon’s largest customer base and highest revenue-generating marketplace. For many Amazon sellers, this means the biggest potential upside in terms of sales and profitability.
Diversification & Risk Management
Expanding into Germany, the UK, or Japan helps you diversify your business and reduce dependence on a single marketplace. It’s smart to spread risk, especially if your inventory or demand in one country slows down.
Efficient Logistics & Support
Many Amazon Consultants, like EHP Consulting Group, recommend using FBA (Fulfillment by Amazon) and tools tailored to these mature marketplaces to streamline shipping, returns, and customer support.
📦 Challenges & Considerations for International Selling

While the opportunity is huge, selling in multiple countries also comes with challenges:
- Regulations and Taxes: Each Amazon marketplace has its own VAT, import duties, and legal considerations.
- Localization: Language, product safety standards, and customer preferences differ significantly.
- Inventory Distribution: You’ll need to decide whether to ship inventory into each country’s FBA warehouses or use global fulfillment strategies.
- Competition: Mature markets like the U.S., Germany, and the UK are highly competitive, so pricing, PPC, and product differentiation are key.
🌐 Cross-Border Fulfillment Options

When expanding to top Amazon marketplaces like Germany, the UK, or Japan, international sellers must consider how to fulfill orders efficiently. Amazon provides FBA Export and Pan-European FBA as key solutions. With FBA Export, sellers can ship from their U.S.-based inventory to international customers without needing multiple warehouses.

Alternatively, Pan-European FBA allows sellers to store inventory in one EU country—like Germany—and Amazon automatically distributes stock across European fulfillment centers based on demand. This reduces delivery times for EU customers and can save on fulfillment costs. Sell on Amazon+1

📊 Navigating International Taxes & VAT

One of the biggest hurdles for Amazon sellers going global is handling Value-Added Tax (VAT). For EU sellers or those expanding into Europe, VAT registration is mandatory in countries where you store your inventory. sell.amazon.co.jp+1
There’s also the question of import duty. If you use FBA, you may need to choose between DDP (Delivered Duty Paid) or DDU (Delivered Duty Unpaid) when shipping inventory. With DDP, you absorb import costs upfront; with DDU, customers may pay at delivery, but this can hurt conversion. sell.amazon.co.jp

🚀 Strategy & Risk Management for Global Scaling
Expanding into high-sales Amazon marketplaces like Germany, the UK, or Japan can diversify your income source—but it comes with risks. According to cross-border sellers, common issues include inventory forecasting, long lead times, and local customer behavior differences. Daily Business Post
To mitigate risk, many successful global sellers use multi-country inventory (MCI) strategies. With MCI, you send stock to select markets that demand the most volume, instead of trying to be everywhere at once. Carbon6

💬 Final Thoughts
The United States remains the dominant Amazon sales market, but other regions like Germany, the UK, and Japan offer strong growth opportunities.
