Embedding FAQ
Is the embed free?
Yes — completely free, with no account needed. The widget includes a “Powered by CalcMyTariff” attribution link — this is standard identification for embedded tools, not a payment or SEO requirement.
Can I change the colors or hide the branding?
Not in this version. Every embed shows the standard CalcMyTariff look so users know where the data comes from. You can set a default country and product to match your audience.
Will the rates stay accurate?
The widget always pulls the current rates from CalcMyTariff, so it stays in sync automatically. Figures are estimates — your readers should confirm with US Customs and Border Protection or a licensed broker before relying on them.
Does it work on WordPress / Webflow / Squarespace?
Yes. Paste the snippet into a Custom HTML / Embed block. The auto-resizing script is a single standard <script> tag.
