Selling internationally on Shopify is genuinely achievable for brands of any size - the platform supports it well. What it doesn't do is handle the complexity that comes with crossing borders for you. Customs regulations, duty calculations, carrier restrictions, and customer expectations around delivery times are all your responsibility to configure correctly.
The basics: shipping zones and rates
Start in Shopify admin → Settings → Shipping and delivery. Create a shipping zone for each group of countries you plan to ship to. A UK brand typically starts with three zones: UK domestic, Europe, and Rest of World.
For international zones, you have three rate options:
- Flat rate - simple and predictable, but may not cover your actual shipping costs accurately for heavy or large items going long distances
- Price-based rates - the shipping rate changes based on order value. "Orders £0–£50: £12 shipping. Orders over £50: £8 shipping." Easy to configure, gives customers a predictable cost
- Carrier-calculated rates - real-time quotes from DHL, FedEx, Royal Mail International, etc. Requires accurate product weights in your Shopify admin. Available on Shopify plans above Basic (or as a paid add-on on Basic)
Duties and customs: the critical decision
When you ship internationally, goods crossing borders may be subject to import duties and taxes payable by the recipient. There are two ways to handle this:
Delivered Duty Unpaid (DDU). The customer pays duties when the parcel arrives in their country. This is the default for most small international shippers. The problem: customers often don't expect the additional charge, feel surprised and annoyed by it, and in some cases refuse delivery. This creates a return problem and damages the customer relationship.
Delivered Duty Paid (DDP). You collect duties at checkout and pay them to the carrier or customs authority on the customer's behalf. The customer pays a single total price with no surprises at delivery. Shopify Markets supports DDP through its international duty collection feature - you configure it for specific markets and Shopify calculates and collects the duty at checkout.
DDP creates a significantly better international customer experience. For markets where duties are significant (post-Brexit UK-EU trade, UK-US shipments over $800), collecting duties at checkout is worth the additional complexity.
VAT and international tax
International sales create VAT and sales tax obligations that vary by country:
EU sales from the UK. Since Brexit, UK-based merchants selling to EU customers need to consider EU VAT registration for shipments under €150 (the EU OSS scheme applies). For orders above €150, duties apply at the border. This is complex - get advice from an accountant with international ecommerce experience before you start selling into the EU at volume.
US sales. Sales to the US may be subject to state sales tax once you exceed economic nexus thresholds in specific states. Shopify can collect US sales tax automatically if configured - go to Settings → Taxes and duties → United States and set up your US tax collection. An accountant or tax compliance app (TaxJar, Avalara) helps if you're selling to the US in meaningful volume.
Australian GST. Australia requires overseas sellers to collect GST (10%) on sales below AUD$1,000 when selling to Australian consumers. Shopify handles this if tax collection is enabled for Australia in your settings.
Carrier options for international shipping
Your carrier choice affects cost, delivery time, and tracking visibility for international shipments. The main options for UK-based merchants:
Royal Mail International. Good for small, lightweight parcels. Tracking is limited on budget services. Economy options are slow (3–6 weeks to the US or Australia). Tracked services (Royal Mail International Tracked) are better but still slower than express couriers.
DHL Express. 2–3 day delivery worldwide with full tracking. More expensive than Royal Mail but significantly faster and with better tracking visibility. Worth the cost for products above £80 where delivery experience matters to the customer relationship.
UPS and FedEx. Similar positioning to DHL - reliable, tracked, 2–5 day international delivery. Compare rates for your typical package weight and destination - pricing varies by carrier and destination.
Parcel forwarding (for complex routes). For destinations where direct shipping is expensive or complicated, parcel forwarding services (Shipwire, ShipBob) allow you to ship to a local fulfilment hub and deliver domestically within the destination country. Higher setup cost but can significantly reduce per-order shipping costs in target markets at volume.
Setting customer expectations
International shipping creates customer experience challenges that domestic shipping doesn't have: longer delivery times, customs delays outside your control, and duties surprises if you haven't implemented DDP.
Handle these proactively:
- Show estimated delivery times per country on your shipping policy page and in checkout
- Send tracking information promptly - international customers are more anxious about parcel location than domestic ones
- If you ship DDU, include a note in your order confirmation explaining that import duties may apply and giving customers a way to calculate them
- Have a clear policy for what happens when customs delays a parcel - it won't be your fault, but the customer will contact you about it
The brands that build successful international businesses treat the international customer experience as a product decision, not just a logistics decision. The checkout, the communications, and the delivery experience all contribute to whether an international customer buys again.
