The Essential Guide to Using Our Worldwide Customs Calculator Before You Ship
International shipping comes with one of the most common and costly surprises in e-commerce and parcel forwarding — unexpected customs charges. A product that looks like a bargain can quickly lose its appeal when import duties, VAT or other charges arrive at the border. The good news is that most of these costs can be estimated before you ship. Send2Hub's free Worldwide Customs Duty and Tax Estimator is designed to do exactly that — giving you a clear picture of likely import costs before you commit to shipping.
Why Estimating Customs Costs Before You Ship Matters
Customs duties and taxes vary enormously by country, product type and declared value. Without estimating in advance, you risk paying significantly more than expected at delivery, having parcels held at the border due to incomplete documentation, pricing products incorrectly for international markets, and losing the financial benefit of a deal or promotion to import charges.
This has become even more important in 2026. The EU introduced a new flat customs duty of €3 per item category on low-value parcels from 1 July 2026, and the US suspended its $800 duty-free de minimis threshold in August 2025. If you are shipping to the EU or the USA, the landed cost calculation has changed significantly. See our full guide to US customs changes and our country guide for destination-specific details.
What the Send2Hub Customs Estimator Does
The Send2Hub customs estimator calculates an estimate of import duty, VAT or local sales tax and the total landed cost for shipments from the UK to virtually any destination worldwide. It is built on the same Harmonised System (HS) classification framework used by customs authorities around the world, and it accounts for UK trade agreements, product-specific duty rates and destination-country thresholds. Results are displayed in both British Pounds Sterling and the local currency of the destination country, using real-time exchange rates.
Estimates can be saved and exported as a PDF — useful for record-keeping, pre-shipment planning and sharing with clients or customers.
How to Use the Customs Estimator — Step by Step
Step 1 — Select your destination and item origin
Choose the destination continent and country for your shipment. This loads the specific customs data — duty rates, VAT rates and any applicable de minimis thresholds — for that country. Then select the item origin country. This is important because UK trade agreements (with Australia, New Zealand, Japan, EU and others) can significantly reduce or eliminate customs duty on goods that genuinely originate in the UK.
Step 2 — Specify your product category
Select the product category that best describes your item. Duty rates vary substantially between categories — electronics, clothing, cosmetics, food products and luxury goods are all assessed differently. Selecting the correct category is the most important factor in getting an accurate estimate.
Step 3 — Enter item value and shipping cost
Enter the declared value of your item and the cost of shipping. Most countries calculate import duties on the CIF value — Cost + Insurance + Freight — meaning both the product value and shipping cost are included in the taxable base. A few countries (including Australia and New Zealand) calculate on FOB (product value only). The estimator applies the correct calculation method for each destination automatically.
Step 4 — Add your HS code (optional but recommended)
For the most accurate calculation, enter the Harmonised System (HS) tariff code for your product. HS codes are six-digit international product classifications used by customs authorities worldwide to apply precise duty rates. Using the correct HS code eliminates the ambiguity of broad product categories and gives you the most accurate possible estimate. The estimator tool includes guidance on how to find the right HS code for your product.
Step 5 — Select shipment type and calculate
Specify whether your shipment is commercial (sold or purchased goods) or a private gift. Some countries offer reduced duty rates or higher de minimis thresholds for genuine private gifts. Once all fields are complete, click Calculate Estimated Costs for an instant breakdown of estimated duty, VAT or GST, and total landed cost.
Understanding the Key Customs Concepts
De Minimis Threshold
The de minimis threshold is the declared value below which a country does not collect customs duty or VAT. Thresholds vary enormously by country — from USD $800 in the USA (now suspended) to as little as EUR 27 in Turkiye. The estimator applies the correct threshold for each destination automatically.
Harmonised System (HS) Codes
The Harmonised System is an internationally standardised product classification system maintained by the World Customs Organisation. Almost every country uses HS codes to classify goods and apply duty rates. A six-digit HS code identifies a product category at the international level — individual countries then extend this with additional digits for more specific classifications. Using the correct HS code for your product is the foundation of accurate customs estimation.
CIF vs FOB Value
CIF (Cost + Insurance + Freight) includes the product value, insurance and shipping cost in the taxable base. FOB (Free On Board) includes only the product value. Most countries use CIF, meaning a high shipping cost increases the amount on which duty is calculated. This makes parcel consolidation particularly valuable — consolidating multiple items into one larger shipment typically results in a lower average shipping cost per item.
Important Customs Changes for 2026
EU — new flat customs duty from 1 July 2026: A flat duty of €3 per item category (HS code) now applies to all parcels valued at €150 or below entering any EU country. This is in addition to local VAT which already applied. The estimator reflects this change for EU destinations.
USA — $800 de minimis suspended from 29 August 2025: All shipments from the UK to the USA are now subject to import duties regardless of value. Send2Hub collects an estimated customs charge of approximately 15% of the declared goods value upfront before dispatching US-bound shipments. See our full guide to US customs changes and our USA shipping page for details.

Important Disclaimer
All figures provided by the Send2Hub customs estimator are estimates only. Final charges may vary based on specific customs inspections, local fees, additional surcharges and the exact HS code applied by the destination country's customs authority. For shipments of significant value or complex product categories, we recommend consulting an official customs authority or professional customs broker for definitive advice before shipping.
Frequently Asked Questions
Is the Send2Hub customs estimator free to use?
Yes. The customs duty and tax estimator is completely free and does not require you to have a Send2Hub account. Simply visit the estimator page, enter your destination, product category and declared value, and get an instant estimate. No sign-up required.
How accurate are the customs estimates?
The estimator provides indicative figures based on the duty rates, VAT rates and de minimis thresholds applicable to each destination. Results are most accurate when a correct HS tariff code is entered. Estimates should be used for planning purposes — actual charges may differ based on customs inspection outcomes, local surcharges and the specific tariff classification applied by destination customs authorities.
What is an HS code and do I need one?
An HS (Harmonised System) code is a six-digit international product classification number used by customs authorities worldwide to apply duty rates. Entering the correct HS code gives you the most accurate estimate. Without it, the estimator uses broader product category rates which may be higher or lower than the specific rate that applies to your item. The estimator tool includes guidance on finding the right HS code for your product.
Does the estimator account for new EU and US customs changes in 2026?
Yes. The estimator reflects the new EU flat customs duty of €3 per item category for parcels valued at €150 or below (effective 1 July 2026) and the suspension of the US $800 de minimis threshold (effective 29 August 2025). Both changes are significant for customers shipping to EU or US destinations.
Can I save my customs estimate?
Yes. Once you have your results, use the Save This Calculation button to export and download a PDF of your estimate. This is useful for record-keeping, pre-shipment planning and sharing cost breakdowns with customers or clients before they place an order.
