🧩 Free · No signup · Works on every AliExpress region
Stop guessing what AliExpress will cost after customs.
The AliExpress Tariffs Chrome extension overlays the real landed cost — product + shipping + duty + VAT — on every product page. No more switching tabs, copying URLs, or refreshing the calculator. Choose your country once. We do the maths every time.
Compatible with Chrome, Edge, Brave, Opera, Vivaldi, and Arc. Manifest V3.
Built for cross-border shoppers, dropshippers, and importers
AliExpress is a maze of currency switches, hidden shipping costs, regional taxes, and constantly-shifting tariffs. Our Chrome extension turns that maze into one line: the actual price you’ll pay. Here’s what it does, why it matters, and how it works under the hood.
One-click install, zero config
Add to Chrome, pick your country in the popup, and you’re done. The badge appears on every AliExpress product page from then on — no copy-paste, no URL pasting, no math.
Reads the live page price
The extension reads the price element directly from AliExpress’s DOM (the same one you see). It handles regional variants, multi-currency switching, and promotional banner prices. If AliExpress changes the markup, we ship an update within hours.
Daily-refreshed tariff rates
Every morning at 04:00 UTC, our pipeline queries an AI model trained on customs documentation to refresh tariff and VAT rates for 30+ countries. The extension caches the result locally so you get a snappy badge with no API call per page.
Affiliate-supported, never sold
If you buy through the extension’s “Buy on AliExpress” button, we earn a small affiliate cut from AliExpress (not you). That keeps the extension free forever. Your data stays on your device.
Multi-region AliExpress support
Works on aliexpress.com, aliexpress.us, aliexpress.ru, and the European storefronts (.es, .fr, .de, .it, .pl). Currency detection is automatic.
Privacy by design
The extension only requests access to AliExpress domains. We do not read any other websites, do not collect browsing history, and do not require an account. Source of every API call is logged in our public docs.
Why a Chrome extension beats a website calculator
We built the web calculator first. It works. But after watching real shoppers use it, we noticed three repeating frustrations — and built the extension to eliminate them.
The copy-paste loop
You find a product on AliExpress, copy the URL, open a new tab, paste it into the calculator, wait, see the result, go back to AliExpress, find the next product, repeat. The extension cuts this loop to zero — the badge is already on the page when you land. For dropshipping research, this saves 20+ minutes per session.
Country-switching fatigue
If you’re comparing prices for two different countries (because you ship to both, or because you’re unsure which warehouse charges less), the extension popup lets you toggle countries in one click and re-renders the badge live. The website requires re-running the calculation.
Surprise at checkout
The single biggest complaint about AliExpress is hidden tariffs revealed after the order is placed — sometimes weeks later via a customs invoice. By showing the duty + VAT before you click Buy, the extension makes the surprise mathematically impossible.
How the extension works (technical)
For readers who want the receipts: here’s exactly what the extension does, in order, when you load a product page.
- 1
Detect the page
It checks the URL against a strict regex for AliExpress product URLs (
/item/[0-9]+.htmlon any AliExpress subdomain). If it’s not a product page, nothing runs. - 2
Read the price
The content script reads the visible price element — the same element you see — using a CSS selector that targets
.price-default--current--*and a few fallback selectors for the older marketplace layout. - 3
Normalize the currency
Prices like “US $12.34” or “€11.45” or “BDT 315.50” are parsed into
{ amount, currency }and then converted to USD. AliExpress switches currencies based on your account/region — the extension handles all of them. - 4
Look up your country’s rate
It checks an in-browser cache for today’s tariff + VAT for the country you saved. If the cache is older than 24 hours, it calls our public
/api/tariffsendpoint over HTTPS. - 5
Compute landed cost
Same formula as the website:
(product + shipping) × (1 + duty) × (1 + VAT), with a de-minimis check that zeroes out the duty when applicable (e.g. US ≤ $800). - 6
Render the badge
A non-intrusive panel is injected next to the price. The panel uses Shadow DOM to avoid clashing with AliExpress styles. Click it to open a breakdown, change country, or open the full result on AliTariffs.com.
FAQ
Does the extension work without an account?▾
Yes — that’s the whole point. Install it, choose your country once, and the landed cost shows on every AliExpress product page. No signup, no email, no payment.
What permissions does the extension need?▾
It only requests access to *.aliexpress.com pages so it can read the product price. It does not read any other websites, does not access your browsing history, and does not require account permissions.
Where does the extension get the tariff rates?▾
From the same daily-updated API the website uses. Rates are refreshed once per day and cached locally in your browser for offline use.
Does the extension cost anything?▾
No. The extension is permanently free. If you want bulk calculation or CSV export, you can upgrade on the website for a one-time $1.99 — but the extension itself stays free.
Does it work on the AliExpress mobile app?▾
The Chrome extension is desktop-only. We are evaluating a mobile companion app — sign up to be notified.
Will the extension slow down AliExpress pages?▾
No. It runs after the page loads and uses a cached rate, so the visible impact is under 50ms. We measured it.
