📦 Import Duty Calculator
Complete guide • How to use, why it matters, real math & FAQs
How to Use This Calculator
The Import Duty Calculator simplifies international trade costs in four simple steps:
1 📝 Describe your product
Enter product description (e.g., "wireless bluetooth speaker") and click the "AI" button for an HS code suggestion, or manually select from the dropdown list of common codes.
2 🌍 Origin & Destination
Select the country of manufacture (origin) and the import country (destination). The calculator understands trade agreements — Vietnam → US triggers FTA benefits automatically.
3 💰 Enter costs
Fill in product value, shipping, and insurance. The calculator computes CIF (Cost + Insurance + Freight) — the dutiable value used by customs worldwide.
4 ⚡ Simulate & verify
Click "what-if simulation" to compare alternative sourcing scenarios. Use "fetch from API" above to pull live UK duty rates from the official government tariff database.
Pro tip: Always click "Recalc" after changing any input — the results update instantly to show your true landed cost including duties, VAT, and extra fees.
Why It Matters
Importers lose thousands of dollars annually by underestimating landed costs. A $299 product with $35 shipping sounds profitable until duty (5.5%), VAT (9%), and fees add $48+ to your true cost. Worse, many shippers discover anti-dumping duties or preferential Free Trade Agreement (FTA) rates only after goods arrive. This calculator reveals your true landed cost before you buy, protecting your profit margins and preventing expensive customs surprises. With live UK Tariff API integration, you get official government rates — not generic estimates.
The Math Behind It — Real Example
Example: Importing a Bluetooth Speaker from China → United States
| Product value | $299.00 | |
| + Shipping | $35.00 | |
| + Insurance | $12.00 | |
| = CIF (dutiable value) | $346.00 | (Cost + Insurance + Freight) |
| × Duty rate (5.5%) | × 0.055 | |
| = Import Duty | $19.03 | ($346 × 0.055) |
| CIF + Duty | $365.03 | |
| × VAT rate (9%) | × 0.09 | |
| = VAT amount | $32.85 | |
| TOTAL LANDED COST | $397.88 | CIF + Duty + VAT |
Now compare sourcing from Vietnam instead: Under US-Vietnam FTA, the same speaker qualifies for 0% duty. Landed cost drops to $378.85 — saving $19.03 per unit. On 1,000 units, that's $19,030 extra profit.
Frequently Asked Questions
Does the UK Tariff API require an API key?
No — the UK government provides free public access to trade-tariff.service.gov.uk/api. Rate limits are generous (60 requests/minute), and no authentication is required. Perfect for real-time duty lookups.
What is CIF and why does it matter?
CIF = Cost + Insurance + Freight. Most countries calculate import duty on the CIF value, not just the product price. Forgetting shipping and insurance leads to costly underestimates — sometimes 15-30% higher than expected. This calculator always uses CIF for accuracy.
Are these rates legally binding?
The live UK Tariff API returns official UK government rates — these are accurate for UK imports. For other countries (US, EU, etc.), the calculator uses demo duty rates based on standard tariff schedules. Always verify with local customs authorities before shipping commercial goods.
What about de minimis thresholds?
Many countries waive duties on low-value shipments: US: $800, UK: £135, EU: €150. This calculator assumes shipments above these thresholds. For small personal imports, your actual duty may be $0. Check your local threshold before assuming costs.
How do Free Trade Agreements (FTAs) affect my duty?
The calculator automatically detects FTA scenarios. For example, Vietnam → US triggers 0% duty on electronics under the US-Vietnam BTA. If your origin country has a trade agreement with your destination, duty may be reduced or eliminated — saving significant money.
