International Selling and Customs

01

Why international is worth considering

For some categories, international demand is not incremental — it is the market. Scarcity is regional. An item that is common where you are may be genuinely difficult to obtain elsewhere, and the price difference reflects that rather than a buyer overpaying.

• Regional scarcity. Local editions, discontinued models, and domestic-market goods that never shipped abroad.
• Thin domestic demand. A specialist item may have a handful of serious buyers in your country and thousands worldwide. For slow-moving stock, opening internationally is often the difference between a sale and dead stock.
• Collector categories. Collectors search globally by default and treat cross-border purchase as routine.
• Currency and price differences. Sometimes favourable, and worth understanding before assuming your prices are competitive abroad.

The counterweight is that international orders are more expensive to fulfil, slower to complete, and harder to unwind when something goes wrong. The right question is not whether to sell internationally but which of your categories carry enough margin and enough advantage to justify it.

02

Who pays duty, and why buyers get angry about it

The most common cross-border failure has nothing to do with shipping. It is a buyer receiving an unexpected demand for money before they can have their parcel, and blaming the seller.

Whichever applies, say so in the listing plainly. A buyer told in advance that import charges may apply and are their responsibility is a buyer who does not open a case about it. The rules, thresholds, and collection mechanisms differ by destination country and change periodically, so state the principle rather than quoting figures that will go stale.

03

Declarations, and why you fill them in honestly

Every cross-border parcel carries a customs declaration describing what is inside, what it is worth, and what it is made of. Buyers will sometimes ask you to understate the value or mark a sale as a gift. Do not.

• It is a false declaration to a government. The consequences fall on you, and they are not proportional to the amount saved.
• It destroys your insurance. Compensation is limited to the declared value. Under-declaring a valuable item means that if it is lost you have written off the difference yourself.
• Customs authorities compare declarations to reality. Inspection is routine, and a mismatch delays the parcel, can trigger penalties, and puts your future shipments under closer scrutiny.
• The buyer who asked will not share the consequences. If the parcel is seized or the claim fails, the dispute is with you.

1. Describe the goods specifically "Vintage camera, 35mm film, non-working" rather than "electronics". Vague descriptions cause holds, and holds cause item-not-received disputes.
2. Declare the price actually paid Including postage where the destination requires it. This is what the declared value means.
3. Use the right commodity code Tariff classifications determine the duty rate. Getting them approximately right speeds clearance; getting them wrong causes delays and incorrect charges. Look up the codes for the categories you ship regularly, once, and reuse them.
4. State the country of origin correctly Where the goods were made, not where you are posting from. Trade agreements can depend on it.
5. Register for any scheme that applies to you Several regions operate import VAT or tax schemes for distance sellers and marketplaces, with registration and reporting obligations that depend on your volume and where you sell. Confirm what applies to your situation with an accountant familiar with cross-border trade — this is genuinely jurisdiction-specific.

Restricted goods and destinations

Plenty of items that are entirely ordinary domestically cannot cross a border, or cannot cross a particular one. This catches sellers who assumed the only question was postage.

• Lithium batteries, including those inside devices. Rules vary by carrier and by whether the battery is installed, packed with, or separate. This affects a very large share of modern electronics.
• Liquids, aerosols, and pressurised items, including many cosmetics and cleaning products.
• Organic and animal-derived materials. Ivory, fur, feathers, shell, exotic leathers, some woods, and taxidermy are restricted or prohibited under international conventions and national law. Antique status does not automatically exempt an item.
• Food, plants, and seeds, which are among the most frequently seized categories.
• Weapons and replicas, where definitions vary enormously and an item legal to own domestically may be prohibited at the destination.
• Alcohol and tobacco, which are almost always specially controlled.
• Sanctioned destinations, which change and are not optional to observe.
• Region-restricted brands, where a genuine item may still breach a distribution agreement — see authentication and counterfeit risk.

The practical approach is to check your carrier's prohibited and restricted list for the destinations you actually ship to, for the categories you actually sell, once — and to re-check when you add a new category. Marketplace blocked-destination settings are worth configuring properly rather than leaving at defaults; a sale you cannot legally fulfil is worse than a sale you never made.

Operational differences that catch sellers out

1. Delivery windows are long and variable Customs clearance is not a queue you can observe. A parcel can sit for weeks with no tracking movement and then arrive. Set delivery estimates generously, because an optimistic estimate turns a normal clearance delay into an item-not-received case.
2. Tracking coverage degrades at the border Some services stop updating once the parcel leaves the origin country. For anything valuable, use a service with genuine end-to-end tracking — without it you cannot win a not-received dispute.
3. Returns are disproportionately expensive Return freight on an international order can approach the item's value, and the item may face import charges coming back to you. Some sellers refund without requiring return above a certain cost threshold, purely because it is cheaper. Decide the policy in advance.
4. Consumer law follows the buyer Rights on cancellation and returns can be governed by the buyer's jurisdiction and can exceed your stated policy. Selling internationally means accepting the strictest applicable rules, not your own.
5. Language and expectation gaps Condition vocabulary, sizing conventions, voltage and plug standards, and regional formats all differ. Photographs and structured attributes travel across languages far better than prose does — see item specifics and structured data.
6. Currency and payout Conversion happens somewhere, and it has a cost. Check whether the rate and fee are on the platform, the payment processor, or your bank, because it is easy to be charged twice.

None of these is a reason to avoid international selling. They are reasons to price it properly and to set expectations in the listing, which is where nearly all cross-border disputes are actually prevented.

Deciding whether it is worth it

Treat international as a channel decision, made per category, with the same discipline as choosing where to sell.

1. Start with high-value, low-weight, non-restricted categories. These carry the freight cost easily and rarely hit prohibitions. This is where cross-border selling is unambiguously good.
2. Avoid heavy, bulky, or low-margin items entirely. Freight will exceed the margin, and no optimisation fixes that.
3. Open a small number of destinations first. Countries you understand, with straightforward import processes and reliable services, before opening everywhere.
4. Price for the realistic total cost, including a higher allowance for loss, delay, and returns than you use domestically.
5. Consider platform-managed programmes. Several marketplaces offer schemes where you ship domestically to a hub and the platform handles export, customs, and often the not-received risk. The economics vary, but the reduction in complexity is substantial for sellers starting out.
6. Review by destination after a few months. Cost, delay, and dispute rate are not uniform across countries. Most sellers find a handful of destinations produce most of the problems, and closing those is a small loss of revenue for a large reduction in work.
