Why these are free, and what that costs you
Nothing here asks for an email, and none of it is a trial of something else. Scriphouse makes money when a duty-credit scrip changes hands, and a reader who can work out their own duty bill is a reader who can tell whether a scrip is worth their time. The tools are useful to us because they are useful to you, which is the only arrangement that survives contact with a second visit.
What it costs you is that the answers are as good as the primary sources and no better. Every figure names the instrument it comes from, the sources behind them are re-checked on a schedule and each tool says when that last happened, and where the sources do not settle a question the tool says so rather than filling the gap. That is slower to read than a single confident number, and it is the difference between a figure you can put in front of a customs broker and one you cannot.
What is here today
Four things, and they are listed above because they exist. There is no roadmap on this page and no waiting list. When the next tool works, it will appear here, and until then this page will not pretend otherwise.
Two of them are the same shipment seen from opposite ends. The customs duty calculator answers what a Bill of Entry will cost an importer; the RoDTEP calculator answers what a shipping bill will earn an exporter, and then what that entitlement is worth in cash once it becomes a scrip. Between them they cover both sides of the trade a duty-credit scrip moves across, and the tariff pages under them hold the schedule both are read against.
