FAQ
Answers to common questions.
- Is it really free?
- Yes, the calculator is free forever for importers. Unlimited calculations, PDF receipts, citations, embed widget. Revenue comes from the exporter side of the marketplace, not from the importer.
- Where do your rates come from?
- Every number cites its primary source. US rates come from USITC HTS (9903.xx headings for overlays), 19 CFR (fees), CBP CSMS bulletins, and Federal Register proclamations. EU rates come from TARIC. UK from HMRC. India from CBIC. Brazil from Receita Federal. FX rates from Frankfurter and FRED. Refresh cadence is documented per source.
- How do you keep up with tariff changes?
- Automated ingestion pipelines refresh HTS, CROSS rulings, EU TARIC, UK Trade Tariff daily. AD/CVD orders, restricted parties, FRED macro data run on their own cadence. CBP CSMS bulletins are scraped for Chapter 99 heading announcements so new overlays (S338 Canada, S232 pharma, S301 forced-labor) land in the engine the day they publish.
- What do you not calculate?
- US state sales/use tax (post-sale, remitted separately). Broker exam-fee expected value is shown as a separate risk-adjusted line, not folded into the base landed cost. Bond premium is amortized only when you tell us your bond type.
- Do you sell my invoices?
- No. Invoices are tied to your account and never shared with third parties. See our privacy policy for the full data handling detail.
- How do I embed it on my site?
- Two lines of HTML. See the embed docs at /en/docs/embed. No API key, no signup required for the embed itself.
- Do you have an API?
- The embed widget covers most use cases. A full REST API is available for white-label partners. Contact us for terms.
