International Shipping for Ecommerce Stores
Deciding Which Countries to Ship To
Start with your analytics data. Check Google Analytics or your ecommerce platform reports for the countries generating the most website traffic, add-to-carts, and checkout attempts from international visitors. If you see significant traffic from Canada, the UK, and Australia but minimal traffic from other countries, start by enabling shipping to those three markets rather than trying to ship worldwide on day one.
Canada is the easiest international market for US-based sellers. Geographic proximity means lower shipping costs and faster transit times (3 to 7 business days via ground, 2 to 3 days via express). The USMCA trade agreement reduces or eliminates duties on many product categories. English-language marketing materials work without modification. Most US carriers offer straightforward Canada shipping services with customs clearance built into the process.
The UK, EU, and Australia are the next most common expansion markets for US ecommerce sellers. All three have high consumer spending, strong internet penetration, and English-speaking populations (for the UK and Australia). However, each has distinct customs requirements. The UK charges 20% VAT on all imports. EU countries charge VAT ranging from 17% to 27% depending on the country. Australia charges 10% GST on imports valued over AUD $1,000. Understanding these requirements before you start shipping prevents angry customers who receive unexpected customs bills.
Some countries are impractical for small ecommerce sellers due to high theft rates, unreliable postal systems, complex customs processes, or import restrictions. Countries with known delivery reliability issues include Brazil (customs delays of 30 to 90 days are common), Russia (sanctions and payment restrictions), India (complex import duties), and several African and Southeast Asian countries with underdeveloped postal infrastructure. Research each market before enabling it.
Step-by-Step Setup
Review your website analytics for the top 5 to 10 countries by traffic volume, add-to-cart actions, and checkout abandonment from international visitors. High checkout abandonment from a specific country often means customers want to buy but cannot because you do not offer shipping to their location. Prioritize countries with the highest purchase intent, proximity to the US (Canada and Mexico ship faster and cheaper), English-speaking populations (reducing support costs), and reliable postal infrastructure.
Every country has its own list of prohibited and restricted import items. Cosmetics, food products, electronics with batteries, and products containing certain chemicals face import restrictions in many countries. Check each destination country's customs website or use a service like Zonos, Avalara, or Global-e to look up product importability by country. Also verify labeling requirements. The EU requires metric measurements, country of origin labels, and specific safety certifications (CE marking) for many product categories. Selling products that cannot legally enter a country results in seized shipments, refund requests, and potential legal issues.
Harmonized System (HS) codes are 6 to 10 digit international product classification codes used by customs authorities worldwide to determine applicable duty rates. Every product you ship internationally needs an HS code on the customs declaration. Use the US International Trade Commission's HTS search tool at hts.usitc.gov to find the correct code for your products. Once you have the HS code, look up the duty rate for each destination country. For example, a cotton t-shirt (HS code 6109.10) imported into the UK faces a 12% duty plus 20% VAT. An electronic gadget might face 0% duty but still 20% VAT. Our customs and duties guide explains this process in detail.
DDP (Delivered Duty Paid) means you calculate duties and taxes at checkout, collect them from the customer, and pay them to the destination country's customs authority on the customer's behalf. The customer receives their order without any additional charges. DDU (Delivered Duty Unpaid) means the customer pays duties and taxes to the carrier or customs upon delivery. DDU is simpler for you but creates a terrible customer experience: the customer thinks they paid the full price at checkout, then gets a surprise bill of 15% to 35% of the product value when the package arrives. Many DDU shipments are refused by customers who do not want to pay the unexpected charges, and you lose both the product and the shipping cost. DDP requires more setup but results in higher customer satisfaction, fewer refused deliveries, and fewer chargebacks.
USPS Priority Mail International is the cheapest option for lightweight packages (under 4 pounds) to most countries, with delivery in 6 to 10 business days. Tracking is included but less detailed than express services. UPS Worldwide Express and Saver provide guaranteed delivery in 1 to 5 business days with full tracking, customs brokerage, and door-to-door service. UPS is the best option for parcels over 4 pounds and for destinations where tracking reliability matters. FedEx International Priority and Economy compete directly with UPS on speed and pricing, with particular strength in European and Asian markets. DHL Express is the dominant international carrier in many countries outside the US, with the largest global network and the fastest customs clearance in most markets. DHL is often the best choice for shipping to Asia, the Middle East, and developing markets where other carriers have limited infrastructure.
Set up country-specific or region-specific shipping rates in your ecommerce platform. For Shopify, use the Shipping and Delivery settings to create shipping zones for each region (North America, EU, UK, Australia, etc.) and assign rates to each zone. If using DDP, enable a duties and taxes calculation service like Zonos, GlobalE, or Shopify Markets that automatically calculates and collects duties at checkout. Display estimated delivery times clearly for each international shipping option. International customers are more tolerant of 7 to 14 day delivery times than domestic customers, but they need to know what to expect before they purchase.
International Packaging Requirements
International shipments need stronger packaging than domestic orders because they go through more handling points, longer transit times, and rougher conditions during customs inspection. Use double-walled corrugated boxes for anything fragile or valuable. Fill all void space with air pillows or packing paper to prevent shifting during the longer journey. International shipments are more likely to be opened for customs inspection, so ensure the product is well-protected even if the outer packaging is opened and resealed.
Customs declarations must be attached to the outside of every international package. Commercial invoices listing the contents, value, HS codes, country of origin, and sender/recipient information are required. Most shipping software generates customs forms automatically when you print international labels. Verify that the product descriptions on customs forms are specific and accurate. "Electronics" will get flagged for inspection; "wireless bluetooth headphones, model XYZ, made in China" clears customs faster.
Managing International Returns
International returns are expensive enough that you should consider your return policy carefully before enabling international shipping. A return shipment from the UK to the US costs $15 to $40 depending on weight and carrier, plus customs clearance in both directions. For products valued under $30 to $50, it is often cheaper to issue a full refund and tell the customer to keep or donate the product rather than paying for return shipping. For higher-value items, establish a local return address in your major markets through a returns consolidation service, or negotiate return shipping rates with your international carrier.
