Enter the HS code, country of origin and weight of a product, read the duty rate from the official tariff for each market, and see the duty, import tax and landed cost side by side before you set a price.
This calculator reads duty and import tax from each market's official tariff page for the code you enter, and shows you the page it read and the date it read it. Rates change and depend on the exact goods, the origin and any trade agreement in force, so check the figure against the linked page before you quote it to a buyer, and edit any field that looks wrong. Carrier handling fees, de minimis relief and brokerage charges are not included.

Step 1
The product
These are the same three fields customs asks for: what the item is, where it was made, and how heavy it is. If you do not have the code yet, the HS code lookup narrows it in a couple of questions.
Six digits or more. The first six are the same in every country.
Where the goods were made or last substantially transformed, not where you ship from.
Freight for this shipment: USD 12.00 at 1 kg. Markets that value goods on arrival include this figure in the duty base.
Step 2
Duty and tax by market
Storecheck reads the official tariff page for each market and fills the rates in for you. Every figure stays editable, and each market shows the page it came from and the day it was read, plus a duty risk score for how likely that rate is to change. Leave a market blank if you do not sell there.
Enter an HS code above first.
Keeps this code current in the background, so you do not have to press read again.
United States
Duty on goods only
Duty is normally calculated on the price paid for the goods, without international freight. There is no federal import tax equivalent to VAT, and state sales tax is a separate question tied to where the buyer is, so leave the tax field at zero unless your setup says otherwise.

How is customs duty calculated on a Shopify order?
Duty is a percentage applied to the customs value of the goods. Some countries apply it to the price of the goods alone, others include freight and insurance to the border. Import tax, where it exists, is usually charged on that value plus the duty, which is why the order of the arithmetic matters.
Where do I find the duty rate for my product?
In the destination tariff, under the HS code that fits your goods. The rate can also depend on the country of origin, since a trade agreement may reduce or remove it when you can evidence the origin. Each market below links straight to its official tariff.
Does the weight of the product change the duty?
For most goods duty is charged on value, not weight, so weight affects the freight cost rather than the duty percentage. Some goods, such as certain foods, alcohol and textiles, carry specific duties charged per unit or per kilogram, which the tariff states next to the code.
Who pays the duty and tax, me or the customer?
That depends on the incoterms you sell under. If the buyer is the importer of record they are billed by the carrier on delivery, which is the usual cause of refused parcels. If you collect duty at checkout you pay it and the buyer sees the total up front.
