Only when it moves
A tariff that starts or ends, a new ban, or a change in what a sample order costs at the border. Announced changes come before they start.
Real numbers

Easy to stop
One email for all your alerts, at most once a day, with a link in every one that stops it.
Questions
Good to know
What counts as a change?
A new tariff, surtax or ban that touches your product and where it is made, one that ends, or a change in what a 100 dollar order of it costs at the border by courier. A day without a change sends nothing.
How often will I hear from you?
Only when something changes, at most once a day, in one email for all your alerts. Most months send nothing.
Which products can I watch?
The 9 products in our duty guides, made in any country, on either route. To watch every product in your own store, with the orders behind each one, connect your store in the app.
Is this customs advice?
No. The numbers are estimates from the rules in force, for a sample order. The exact tariff code, your paperwork and the carrier decide what is charged.
How do I stop?
Every alert email has a link that stops that alert and one that stops them all, and your mail app's unsubscribe button works too. A request you never confirm is deleted after 7 days.
