10-Step Checklist for Starting International Shipping (And What Most Sellers Miss)

 

Expanding globally sounds like a big win — until the first customs hold-up lands in your inbox.

Plenty of eCommerce sellers think about international shipping the wrong way. They see it as just "shipping, but farther." In reality, it's a different operation altogether — with its own rules, paperwork, costs, and failure points.

If you're thinking about shipping internationally for the first time, here's what you actually need to think through before your first order goes out the door.

Why International Shipping Trips Up So Many Sellers

Domestic shipping is mostly muscle memory after a while. You know your carriers, your transit times, and how returns work.

Cross-border shipping introduces a whole new layer. Customs documentation, country-specific import rules, tax obligations, restricted product categories — it adds up fast. And the tricky part is that most mistakes don't show up until a package is already stuck somewhere.

A little preparation upfront saves a lot of headaches later.

The 10-Step Checklist for Starting International Shipping

1. Research Your Target Markets First

Before you think about carriers or packaging, know where you're actually shipping. Some countries have tight restrictions on supplements, electronics, food products, or certain materials. What sells well domestically might face import barriers elsewhere.

2. Get Your HS Codes Right

Every product is classified under a Harmonized System (HS) code — a globally standardized number used to calculate duties and taxes. Using the wrong code can trigger delays, fines, or unexpected charges passed on to your customer. It's worth spending time getting this right.

3. Understand How Duties and Taxes Work

Some markets require you to collect VAT or import duties at checkout (this is called Delivered Duty Paid, or DDP). Others push those costs to the buyer on delivery. If your customer isn't expecting a surprise tax bill when their package arrives, you need to sort this out before you launch.

4. Pick the Right Carrier for Each Region

DHL, FedEx, UPS, and national postal networks all perform differently depending on where you're shipping. Transit times, tracking reliability, and rates vary by region. There's no single best carrier — it depends on your destination and your volume.

5. Get Your Documentation in Order

A commercial invoice and packing list are the basics. Depending on what you're shipping and where, you may also need a certificate of origin or compliance documents. Missing or incomplete paperwork is one of the most common reasons shipments get held at customs — and it's entirely avoidable.

6. Know What's Prohibited or Restricted

Every country maintains its own restricted and prohibited items list. Some things can't be imported at all. Others need special permits. This isn't an area to wing it — violations can mean seizure, fines, or being blocked from shipping to that market.

7. Build a Returns Process Before You Need One

International returns are slow and expensive. Figure out your policy before you start selling — whether that's a local returns address in the destination country, a credit-based resolution, or a return-to-sender setup. Customers will ask.

8. Show Accurate Landed Costs at Checkout

The price a customer sees shouldn't be a surprise. Landed cost includes the product, shipping, duties, and applicable taxes. Sellers who display this accurately at checkout see fewer cart abandonments and fewer post-delivery complaints.

9. Make Sure Tracking Works Across Borders

Cross-border tracking has historically been inconsistent, especially once a package changes carrier hands in the destination country. Verify that your carrier or fulfillment partner provides end-to-end visibility — customers expect it, and it reduces support tickets.

10. Use a Checklist Every Time — Not Just the First Time

The details that get missed in international shipping are usually the ones that seemed obvious. Whether you're fulfilling in-house or working with a 3PL, having a structured international shipping checklist keeps the process consistent as your volume grows and new markets come into play.

What the Day-to-Day Actually Looks Like

Even well-prepared sellers hit bumps. A shipment gets flagged at customs. A carrier misroutes a package. A country quietly updates its import regulations.

The difference between sellers who scale internationally and those who pull back isn't a perfect track record — it's having a process that catches problems early and fixes them without derailing everything else.

Start with one or two markets. Get the process working. Then expand. Trying to ship everywhere at once before the foundation is solid is one of the most common mistakes sellers make.

Before You Ship That First International Order

International shipping can genuinely grow your business — but it rewards sellers who treat it as a process, not just a transaction.

Go in with a plan. Build the right habits from the start. And don't skip the paperwork.

Is Temu the Right Sales Channel for Your UK Business? Here's What to Consider

Image
  Temu has grown faster than most people in eCommerce expected. In just a couple of years, it went from an unfamiliar name to one of the most downloaded shopping apps in the UK — and that kind of reach is hard for sellers to ignore. But popularity doesn't automatically make it the right channel for every business. If you're a UK-based seller thinking about Temu, the setup process and business model are different from what you might be used to on Amazon or eBay. Understanding how it actually works before you commit time and inventory is worth doing upfront. How the Temu Seller Model Actually Works Temu operates on a managed marketplace model — which is meaningfully different from platforms where sellers control their own listings and pricing independently. When you sell on Temu, the platform takes an active role in how your products are presented, priced, and promoted. In many cases, Temu sets the customer-facing price, which means your margin is determined by the wholesale rate...

LTL Freight Shipping Explained: What eCommerce Sellers Need to Understand

Image
 At some point, most growing eCommerce sellers outgrow parcel shipping for at least part of their inventory. When a shipment is too large for a standard parcel carrier but not large enough to fill an entire truck, LTL freight shipping is typically what fills the gap. LTL — less-than-truckload — is one of those logistics terms that gets thrown around a lot but isn't always well understood by sellers coming from a parcel-first background. Getting a handle on how it works, and where it tends to go sideways, saves a lot of headaches when you start moving meaningful freight volume. How LTL Freight Actually Works With LTL, your shipment shares trailer space with freight from other shippers. A carrier picks up from multiple points, consolidates the loads at a terminal, and routes everything toward its destination — sometimes with additional stops along the way. That consolidation model is what makes LTL cost-effective compared to chartering a full truckload for a smaller shipment. Bu...

Pallet Calculator: Why Getting Your Pallet Math Right Matters More Than You Think

Image
  Most warehouse and shipping mistakes don't start on the dock. They start on a spreadsheet — or more often, in someone's head when they're estimating how many boxes fit on a pallet without actually working through the numbers. For eCommerce sellers, 3PL clients, and anyone sending freight regularly, pallet calculations affect freight costs, storage fees, carrier compliance, and how efficiently your inventory moves through the supply chain. Getting them wrong consistently is an expensive habit. What a Pallet Calculator Actually Does A pallet calculator helps you figure out how many cartons or units fit on a standard pallet based on box dimensions, weight, and stacking configuration. It removes the guesswork from a calculation that has real cost implications on both ends of the shipping process. The basic inputs are straightforward — carton length, width, height, weight, and the pallet size you're working with. From there, the calculator works out how many layers fit, ho...
