Affiliate disclosure

No outbound link on this page is an affiliate or sponsored link. The Amazon search links in the gear section carry no tracking tag, we are not in the Amazon Associates programme, and we earn nothing if you buy through them. There is no shipping-platform partner and no commission of any kind on this page. The calculator is free to use, and no link ever changes the duty, VAT, or landed-cost figures, which come solely from the tool's own verified formula. If a paid link is ever added, this page names the programme before it goes live.
