The Import Duty Calculator Extension for Any Store, Any Country
Dutix reads the price on any product page and shows the full landed cost - VAT, customs duty, and carrier handling fees - for the EU, UK, China, and the USA. Install it once and it works everywhere, automatically.
Free. No account required. Runs entirely in your browser.
Exactly What the Extension Can Do
Everything below happens automatically, the moment you land on a product page.
Reads the price automatically
No copy-pasting a URL or entering the price by hand. Dutix detects the product price and cart total directly on the page as you browse.
Full landed-cost breakdown
VAT (or sales tax), customs duty, and the carrier's handling fee, itemized separately - not just a single lump-sum guess.
EU, UK, China & US coverage
Dutix applies the correct rules automatically for whichever of these you're shopping into - the €150/£135/RMB 2,000 thresholds, IOSS, CBEC, and Section 301, without you needing to know any of it.
Instant, in the popup
Analysis in under a second, right where you're shopping - no separate tab, no page reload.
Zero data collected
Everything runs locally in your browser. Dutix never sees your cart contents, account, or payment details, and nothing is sent to our servers.
Works on any store
No allowlist to maintain and nothing to configure per retailer - if it's a product or cart page, Dutix can read it, from small independent shops to Amazon.
A Real Breakdown, Not a Single Guessed Number
An example of what the extension popup shows on a typical non-domestic order.
$134.99 more than the price shown on the product page - known before checkout, not after delivery.

Correct Rules for Four Major Destinations

European Union
All 27 member states - the €150 threshold, IOSS, and the new flat €3 duty on sub-threshold orders.
United Kingdom
20% VAT and the £135 duty-free threshold under the UK's own post-Brexit tariff schedule.
China
The personal postal tax bands or the reduced CBEC rate, whichever regime the order actually falls under.
United States
No de minimis exemption anymore - the Merchandise Processing Fee and current duty rate, applied to every order.

Common Questions About the Extension
What exactly does the Dutix extension do?
It reads the price on any product or cart page you visit and calculates the full landed cost - the shown price plus import VAT (or sales tax), customs duty, and any carrier handling fee - so you know the real total before you check out, not after the parcel arrives.
Which browsers does Dutix support?
Chrome and any Chromium-based browser (Edge, Brave, Opera) via the Chrome Web Store today. A Safari version is in development - this page will link to it the moment it's published.
Which countries does the import duty calculator extension cover?
All 27 EU member states, the UK, China, and the USA, each with their own correct VAT/duty rules and thresholds applied automatically based on where you are and where the store ships from. See the worldwide customs duty guide for every destination this site documents.
Does Dutix need my account login or personal data?
No. Dutix only reads the product price and cart total that are already visible on the page - it never accesses your account, payment details, or any personal information, and nothing is sent to our servers.
How does Dutix know the customs duty rate for my order?
It matches the product category and destination against this site's own duty-rate data - the same sourced rates published in the worldwide customs duty guide - so the number in the popup matches what you'd find researching it yourself.
Is the Dutix extension really free?
Yes, completely free. No subscription, no trial period, no credit card required to install or use it.
