How to embed

Copy the snippet below and paste it into your page's HTML (or an embed block in your CMS).
Optional: append ?origin=CN (any ISO 3166-1 alpha-2 code) to preselect the export country for your audience.
Keep the attribution line visible — it is what keeps the tool free for everyone.

Embed code

<iframe id="itt-embed" src="https://invoicetariff.com/en/embed/tariff-calculator" style="width:100%;height:720px;border:0;border-radius:12px" loading="lazy" title="U.S. Tariff & Landed Cost Calculator"></iframe>
<p style="margin:8px 0 0;font-size:12px">Powered by <a href="https://invoicetariff.com/en/tariff-calculator" target="_blank" rel="noopener">Invoice × Tariff</a></p>
<script>
window.addEventListener("message", function (e) {
  if (e.origin !== "https://invoicetariff.com" || !e.data || e.data.type !== "itt:embed:height") return;
  var f = document.getElementById("itt-embed");
  if (f) f.style.height = e.data.height + "px";
});
</script>

The frame resizes itself automatically as content grows — no inner scrolling, and the only script you need is the listener included in the snippet.

URL parameters

?origin=CN — preselect the export country (ISO 3166-1 alpha-2, e.g. CN, VN, IN, DE)

Will it slow my page down?

No. The widget loads lazily after your page renders, and all calculation runs in the visitor's browser — no server round-trips while typing.
