How the AliExpress Tariff Calculator works

A $12 phone case on AliExpress might land at your door costing $19, $14, or $42, depending on where you live. Three things determine the difference:

• Import duty — a percentage of the declared value, set by your country.
• VAT / GST / sales tax — added on top of the dutied value.
• De-minimis threshold — a low-value exemption that varies wildly (US $800 vs. EU $0).

AliExpress doesn’t tell you these numbers up front. We do.

1. You paste a product URL. Our server fetches the page using a standard browser user-agent and reads two things: the product title and the visible price. We use the same DOM selectors AliExpress shows you (e.g. .price-default--current--*), so the price you see is the price we use.
2. We normalize the currency. AliExpress displays prices in your local currency by default. If you’re in Dhaka you might see BDT 315.50; in Berlin you might see €2.41. Our parser handles 25+ currency formats. The number is then converted to USD using a free exchange-rate feed that we cache every 12 hours.
3. We look up your country’s tariff and VAT rates. These come from a Supabase table that’s refreshed every morning at 04:00 UTC by a Claude-powered job. The job queries an AI model trained on customs documentation and asks for today’s effective rate for retail consumer parcels — not the misleading official rate that nobody actually pays.
4. We apply the formula. landed = (product + shipping) × (1 + duty) × (1 + VAT). If the product falls under your country’s de-minimis threshold (e.g. ≤ $800 in the US, ≤ A$1000 in Australia), the duty is zeroed out automatically.
5. We show you the breakdown. Item by item. You can read the source notes, click through to AliExpress with an affiliate-tagged link that doesn’t change your price, or hop to the same calculation for a different country.

This is the part most calculators are vague about, so we’ll be specific.

Customs duty rates are public information. They’re published by your country’s customs authority (CBP for the US, HMRC for the UK, NBR for Bangladesh, and so on). The problem is that the official rate is usually a worst-case general rate — most consumer parcels qualify for a simpler effective rate based on declared value, courier paperwork, and the de-minimis exemption.

Every morning, our pipeline asks an AI model to summarize the effective rate that a typical AliExpress buyer would actually be charged. The model returns its best estimate plus a confidence score (low / medium / high). We store the rate, the confidence, and a short note explaining the model’s reasoning. You see all three on every result page.

For high-confidence countries (where the rate is a simple, widely-published number) you can treat our estimate as authoritative. For low-confidence countries (where rates are tiered, contested, or recently changed), treat the number as a starting point and confirm with your carrier before placing a large order.

We want you to trust the number, which means being clear about its limits.

• HS-code-specific rates. A jewellery item often has a different duty rate than electronics. We use the most common rate for AliExpress-style retail goods; you can override the duty manually if you know your HS code.
• Carrier processing fees. DHL, UPS, and FedEx routinely charge a $5–$25 “brokerage fee” to handle customs paperwork on your behalf. We do not include this — it depends on your shipping method.
• Buyer Protection / Tax recovery programs. AliExpress now collects some VAT on behalf of EU/UK buyers under IOSS rules. If the product page shows “Tax included,” the VAT we display may overlap with what AliExpress already collected. Our notes will flag this when we detect it.
• Future tariff changes. Trade rules change. Our pipeline refreshes daily — but it can be 12 hours behind a sudden policy announcement.

When you calculate, we store the URL you pasted, the country you picked, and the resulting numbers. This is so you can revisit your history. We do not store any AliExpress account information (we never ask for it), and we do not share calculation data with third parties. The affiliate link we wrap is a standard AliExpress short-link — it doesn’t change your price or share your identity.

The Chrome extension stores even less. Your saved country lives in your browser; price data is read once per page view and discarded.
