Import Duties Calculator Cheat Sheet: VAT, GST and De Minimis Rules for the US, UK, EU, Australia and Canada

A de minimis threshold, technically, is the value below which a country decides a parcel is too small to bother taxing. Latin for “about trifles”. It exists so customs officers don’t spend an afternoon assessing duty on a pair of socks.

That’s the textbook version. Here’s the lived one: a text from a courier saying your parcel has arrived, there’s a balance to settle, and delivery is on hold until you pay. No breakdown. No warning at checkout. Just a link and a number.

This post closes that gap. Think of it as an import duties calculator you can run in your head: thresholds, tax rates, who collects and what the carrier adds, market by market, as of late September 2026.

Fair warning: 2026 has been the busiest year for these rules in decades.

How the Bill Is Built

Every import charge you’ll ever see is three things stacked on top of each other. First, customs duty: a tariff on the goods, set by what the item is and where it was made, calculated on the price plus shipping. Many countries waive it below a threshold, and that waiver is the de minimis. Second, VAT or GST: a sales tax on the whole landed value, goods, shipping and duty included. Yes, tax on the tax. Third, the carrier’s handling fee: if the seller didn’t collect at checkout, the carrier pays the government for you and charges a flat fee for the favour. On a cheap order it can exceed the tax itself. Once you can name the layers, the courier’s number stops looking random.

United States: The Threshold That Vanished

For years the US had the most generous de minimis on earth: anything under US$800 sailed in duty-free. Not any more.

What Changed and When

Duty-free treatment was suspended for shipments from all countries in August 2025. Postal parcels, which briefly ran on a temporary system, lost the exemption indefinitely from 24 June 2026, and since 24 July 2026 they clear through a new postal informal entry process covering anything up to US$2,500. In plain English: every parcel entering the US is now dutiable.

What You Actually Pay

Here’s the awkward part for any import duties calculator: there’s no single US rate. Each product carries its own tariff line, and on top sit country-of-origin surcharges that have been introduced, struck down and replaced several times this year. So a seller’s “duties included” option matters more in the US than anywhere else right now. If it’s there, use it. If it isn’t, assume the carrier will bill you and budget high. Expect this section to change again.

United Kingdom: The £135 Line

The UK has the cleanest system of the five, so it’s the best place to learn the logic.

Orders of £135 or Less

The overseas seller or marketplace must charge you 20% UK VAT at checkout, and no duty applies. Nothing further is due at the door, which is why a SHEIN or AliExpress order shows VAT in the basket and then simply turns up.

Orders Over £135

The seller doesn’t charge VAT. The parcel is assessed on arrival instead: duty on goods plus shipping, then 20% VAT on that total including the duty, then a handling fee. Royal Mail charges £8, Parcelforce £12, and £25 applies over £900. You’ll get a Fee to Pay card, text or email, and the parcel waits around three weeks before heading back.

The Change Coming

The government has confirmed it will remove the £135 duty relief, with the new regime due no later than October 2028. VAT at checkout stays; low-value orders will simply attract duty too. Nothing has changed yet.

European Union: Hello, €3 Flat Fee

The EU scrapped its VAT exemption for small parcels in 2021. In 2026 it went after the duty exemption too.

How VAT Works

VAT on international orders to the EU is charged at your own country’s rate from the first euro. Up to €150, sellers registered in the Import One-Stop Shop (IOSS) collect it at checkout, which is why a €40 phone case shows 19% German VAT in the basket. If the seller isn’t in IOSS, the postal operator collects on delivery and adds its fee; Deutsche Post DHL charges €7.50.

The New Duty on Small Parcels

Since 1 July 2026, a flat €3 customs duty applies per item (per tariff category, so two different products in one box means €6) on parcels up to €150. It’s meant to be paid by the seller or their IOSS representative and baked into the price, not billed at your door, and it stays until a permanent replacement lands, expected by July 2028. Above €150, normal duty applies.

Australia: The Calm One

GST on imports to Australia is refreshingly predictable.

Orders Up to A$1,000

Since 2018, overseas sellers, marketplaces and mail-forwarders must charge 10% GST at checkout on consignments worth A$1,000 or less. No duty and no handling fee at the border, because there’s nothing to handle.

Orders Over A$1,000

The seller stops charging GST and the parcel is cleared on arrival: duty plus 10% GST plus the carrier’s clearance charges, all billed to you. The limit is per consignment, so two A$600 items in one order tip you over.

Canada: Two Sets of Rules

Canada is the country most likely to catch you out, because the threshold depends on how the parcel travels.

By Mail

Through Canada Post, only items worth C$20 or less are exempt, and gifts up to C$60. Everything else gets 5% GST plus provincial tax (HST of 13% to 15% in Ontario and the Atlantic provinces), any duty, and Canada Post’s C$9.95 handling fee, payable online before the driver arrives.

By Courier from the US or Mexico

Under the CUSMA trade deal, courier shipments from the US or Mexico get more room: no tax under C$40 and no duty under C$150. Goods from anywhere else, or merely routed through the US, fall back to C$20. Couriers add their own brokerage fees, worth checking before you order.

The Import Duties Calculator, Worked by Hand

Seeing the stacking once makes every future bill legible. You order a jacket from a US retailer for £200, with £15 shipping to the UK. It’s over £135, so no VAT at checkout. On arrival, assume a 12% duty rate (illustrative; check your product).

Step 1: customs value is goods plus shipping, £215.

Step 2: duty at 12% on £215 is £25.80.

Step 3: VAT at 20% on £215 plus £25.80, so on £240.80, is £48.16.

Step 4: Royal Mail’s handling fee is £8.

Total on top of the £200 jacket: £81.96, and the parcel waits until you’ve paid. Run the same jacket at £130 and the answer is 20% VAT in the basket and nothing at the door. The threshold isn’t a small difference. It’s the whole game.

The same four steps work anywhere: goods plus shipping, times the duty rate, add it back, times the local VAT or GST rate, plus the carrier’s flat fee. That’s every import duties calculator online, in one sentence.

How to Avoid the Surprise Bill Entirely

Whether a courier ever texts you comes down to two shipping terms. DDP (delivered duty paid) means the seller charged duty and tax at checkout and pays customs for you, so the parcel clears without a stop. DDU (delivered duty unpaid) means the carrier bills you on arrival, fee included. That’s where surprise bills come from. A few habits remove the drama.

Check the Checkout for a Tax Line

If VAT, GST or “duties” appear as a line item, you’re on DDP and can relax. If shipping to your country shows nothing at all, assume DDU and budget for it. And when a bill does arrive, pay only through the carrier’s official site or app, never a link in an unexpected text.

Stay Under the Threshold Where One Exists

£135 in the UK, €150 in the EU, A$1,000 in Australia, C$150 on US courier parcels to Canada: two smaller orders can beat one big one. Splitting at checkout is fine; splitting one order into two boxes afterwards is not.

Keep Your Tracking in One Place

Import charges appear on the tracking page first, often before the text arrives. Paste the number into a universal tracker such as Parcel Monitor, or let Email Sync pull your order confirmations into one timeline, and a “charges due” status shows up where you’ll actually see it.

The Whole Cheat Sheet in One Breath

Every import bill is duty on goods plus shipping, then VAT or GST on that total, then a flat carrier fee if the seller didn’t collect at checkout. The US has no duty-free threshold any more and its rates keep moving, so look for “duties included”. The UK charges 20% VAT in the basket up to £135 and duty plus VAT plus an £8 to £12 fee above it. The EU charges local VAT from the first euro, mostly at checkout, plus a €3 per-item duty since July 2026 that sellers should bake in. Australia collects 10% GST at checkout up to A$1,000 and clears anything bigger at the border. Canada exempts almost nothing by mail (C$20), gives US and Mexican courier parcels room to C$40 for tax and C$150 for duty, and Canada Post adds C$9.95 to anything taxable.

Where That Leaves Your Next Order

That text from the courier will keep arriving for as long as people order things from other countries. What changes is whether it lands as a shock or as a line you already pencilled in.

Run the four-step sum before you buy, look for the tax line at checkout, and know your threshold. When the message does come, check the number against your own estimate. If it matches, pay and move on. If it doesn’t, you now know which layer to question.

Customs will always take its cut; the least Parcel Monitor can do is make sure you see the “charges due” status before the courier does the asking.
