Ordering a US supplement from abroad: shipping and customs

If you order a US supplement from abroad, expect three extra things: an international shipping fee that is often higher than the US one, a longer delivery time, and possible import charges collected by your own country's customs, which the seller usually does not control. Rules differ a lot by country, so the safe approach is to read the shipping terms before you pay, check your local customs rules, and keep the refund terms in mind, because returning bottles across a border is expensive. This guide uses real order pages from our reviews and the UK government's published rules as a worked example. It is general information, not medical or legal advice.

Do US supplement sellers ship internationally?

Many do, but not all, and the details are often thin on the sales page. In our reviews we see four patterns:

One offer goes the other way. The Rock Hard Formula review records free worldwide shipping on every bundle on the sales page. Free shipping still does not cover import charges at your end, which is the next question.

The policy page is often where the truth sits. The NeuroVera review notes that the site's own shipping policy says the purchase price includes shipping, while international orders outside the US carry extra fees that the sales page does not quote. If the checkout will not show an international total until the last step, stop there, write down the amount, and decide with the full number in front of you. A low headline price with a high shipping line can cost more than a pricier offer with shipping included.

Who pays customs duty and import tax?

Usually the buyer, and the rules belong to the country you live in, not to the seller or to US law. As one example, the UK government says VAT is charged on goods sent from outside the UK to Great Britain, except gifts worth 39 pounds or less. For goods you bought yourself that are worth 135 pounds or less in total, the seller should have included VAT in the price you paid. For goods worth more than 135 pounds, you pay VAT to the delivery company before delivery or on collection, and the VAT is calculated on the value of the goods plus postage, packing, insurance and any duty owed.

Customs Duty in Great Britain works differently by value. For non-excise goods worth 135 pounds or less there is no duty. Above that, the rate depends on the type of goods and where they came from. If you owe anything, Royal Mail, Parcelforce or the courier contacts you with a bill that shows exactly which fees to pay, and the parcel is normally held for about three weeks before it is returned to the sender.

These thresholds are specific to the UK page we loaded in October 2026, and other countries set their own limits and procedures. Check your national customs or tax authority before you order, and look again when you buy, because thresholds change.

Can a supplement be treated differently in your country?

Yes. A product sold in the US as a dietary supplement is regulated under a US law, the Dietary Supplement Health and Education Act. The FDA's overview says manufacturers and distributors are responsible for evaluating safety and labeling before marketing, and that the FDA can act against adulterated or misbranded products after they reach the market. That framework applies in the US. Your country may classify the same capsule differently.

The UK's customs guidance is a useful illustration. It says vitamins, supplements and herbal medicines are classified by their purpose (whether they are medicinal or for general health and well-being), their contents and additives, and the way they are made up, for example for retail sale or in measured doses for a specific use. The same product can therefore land in a different customs category, with different rules, depending on how it is described and what it contains.

The practical step is to read the ingredient list, then check your national health or customs authority about any ingredient you are unsure of. If you take prescription medicine or have a health condition, ask a pharmacist or doctor whether a product is suitable. Formulas such as the one in our ProMind Complex review list their ingredients, which makes that check easier than with a blend that hides them.

What does returning or refunding an international order involve?

A long refund window helps, but it does not solve the return cost. Some offers ask for the bottles to be sent back, and the review lists where. The Protoflow review notes that its FAQ says bottles must be shipped back to the company's address in Aurora, Colorado for the refund to be approved. The Prosta Defend review notes a refund minus shipping and handling fees. If you live abroad, return postage and any customs paperwork may cost more than a bottle is worth, so ask the seller before you buy whether a refund requires a return, and whether the guarantee applies to your country.

If the order runs through ClickBank, requests normally go through ClickBank's order support, as our ClickBank refund guide explains. Digital products avoid the problem: the Return to Prime review notes that nothing is shipped and both the book and bundle are instant downloads, so there is no parcel, no customs and no return shipping.

What should you check before you pay?

1. Find the international fee. If the page does not state it, treat the total as unknown until the checkout shows it.
2. Compare per month. Add shipping to the price, divide by the days the order lasts, and multiply by 30.
3. Ask about import charges. Check your customs authority's thresholds and whether the courier collects at your door.
4. Allow time. If delivery is quoted in weeks, check that your refund window is long enough to cover transit plus your own trial.
5. Check the shipping destination list before you enter your card.
6. Keep the order number and any tracking link until the parcel is cleared.

FAQ

Will I have to pay customs on a supplement shipped from the US?

It depends on your country and the value of the order. In the UK example above, VAT applies to goods from outside the UK, and Customs Duty depends on value and goods type. Check your own customs authority.

Why is international shipping so much more than US shipping?

Our reviews record higher fees, such as $19.95 abroad against $9.95 in the US on one offer. Longer routes and customs paperwork are the usual reasons, though sellers do not always explain.

Can I return a US supplement from another country?

Possibly, but you may pay return postage and the seller may require the bottles back. Ask first and keep proof of shipment.

Is a US supplement allowed in my country?

Not automatically. Countries classify products by purpose and contents, so check your health authority for any ingredient you are unsure about, and ask a pharmacist or doctor if you take medicines.
