What Is Cross-Border E-Commerce and How Do Chinese Sellers Get Started?

Updated

Cross-border e-commerce means selling goods to customers in another country, with the transaction, payment, and delivery all crossing at least one border. For Chinese sellers, the practical starting point is to pick one model (B2C marketplace, DTC store, or B2B wholesale), one target market, and one fulfillment path — then layer payments and compliance on top. This guide walks through each decision in order, using Walmart Connect's retail media business as a concrete example of how the advertising layer fits in once the basics are running.

The three main models, and who each one fits

Model How it works Best for Main trade-off
B2C marketplace You list on an existing platform (e.g., Walmart Marketplace, Amazon) and sell to consumers New sellers who want built-in traffic and don't want to build a store You compete on price and reviews; you don't own the customer relationship
DTC (direct-to-consumer) You run your own store and drive your own traffic Sellers with a differentiated product and a marketing budget You pay for every visitor; no platform traffic comes free
B2B wholesale You sell in bulk to overseas retailers or distributors Manufacturers with capacity and stable supply Longer sales cycles, thinner per-unit margins, more paperwork

Most Chinese sellers start on a B2C marketplace because the traffic already exists. DTC and B2B usually come later, once you know which products sell and at what price.

Step 1: Choose a target market and channel

Pick one country first — usually the US, given its consumer spending and mature logistics. Then decide between a marketplace and your own store.

  • Marketplace route: You inherit the platform's shopper base, checkout, and often its fulfillment network. Your job shifts to listing quality, pricing, and reviews.
  • DTC route: You control branding and margins but must generate demand yourself, typically through paid ads and content.

A middle path is common: sell on a marketplace to validate demand, then use the data to decide whether a DTC store is worth building.

Step 2: Set up logistics and fulfillment

You have three realistic options, and most sellers combine them:

  1. Direct international shipping — you ship each order from China. Cheapest to start, slowest to arrive, worst for returns.
  2. Overseas warehouse — you send inventory in bulk to a warehouse in the target country, then ship locally. Faster delivery, better conversion, but you carry inventory risk.
  3. Platform fulfillment — the marketplace stores and ships your goods for a fee. Least operational work, least control.

Returns handling deserves its own plan. In the US, buyers expect free or cheap returns; if you don't budget for this, it eats your margin.

Step 3: Handle payments, currency, and pricing

You need a way to receive money in the target market's currency and convert it back. Typical setup:

  • A payment processor or the marketplace's own payout system collects from the buyer.
  • Funds settle to you in USD (or the local currency), then convert to RMB.
  • Fees stack: payment processing, currency conversion, platform commission, and ad spend.

Price so that your margin survives all of these. A common mistake is pricing off the product cost alone and discovering after fees that the unit loses money.

Step 4: Cover the compliance basics

Four areas cause most first-year problems:

  • Customs and duties — know the tariff code and duty rate for your product in the target country.
  • Taxes — in the US, sales tax rules vary by state; marketplaces often collect and remit on your behalf, but verify.
  • Product certification — electronics, toys, and cosmetics need specific certifications (e.g., FCC, CPSIA) before they can be sold.
  • Intellectual property — check that your product, brand name, and listing images don't infringe existing trademarks or patents.

Skipping any of these can get a listing removed or inventory seized.

Step 5: Add the advertising layer once sales are running

Once you have listings and inventory, paid advertising is how you scale. Retail media — advertising inside a retailer's own platform — is one option. Walmart Connect, for example, is the retail media business of Walmart, described as the largest US retailer's omnichannel retail media arm, offering full-funnel ad solutions and closed-loop measurement to help Chinese companies reach US consumers and build global brands.

The advantage of retail media over general search or social ads is that it reaches shoppers at the point of purchase, and the platform can measure whether an ad led to a sale. That closed loop is hard to get elsewhere.

Common first-year failure points

  • Picking too many markets at once. Each country has its own rules, language, and logistics. Start with one.
  • Underestimating landed cost. Product cost plus shipping plus duties plus fees plus returns often exceeds the price you assumed was profitable.
  • Ignoring compliance until a listing is blocked. Certification and IP checks should happen before you buy inventory, not after.
  • Spending on ads before the listing converts. Fix your images, title, and price first; ads amplify a good listing and waste money on a bad one.
  • No returns plan. In the US especially, returns are a cost of doing business, not an exception.

Where to go next

If you're at the start, pick one model and one market, then work through logistics, payments, and compliance in that order. If you already sell and want to grow, look at retail media options like Walmart Connect to reach shoppers where they're already buying.
