Paste your codes or upload a CSV. We validate each one against the live USITC schedule.
Our pipeline checks Federal Register orders and USITC schedule changes every night using AI-powered document analysis.
When a rate change affects one of your codes, you get an email: the old rate, new rate, effective date, and a direct link to the source document. No noise — only changes that match your catalog.
Duty rates shift constantly — Federal Register executive orders, anti-dumping determinations, Section 301 modifications. The Federal Register publishes hundreds of documents a day. Nobody reads them all.
ImportSignal reads them for you. When a change hits one of your HTS codes, you get a specific alert: which code, by how much, and the source document — the morning it's published.
Every alert gives you exactly what you need to act.

We monitor two official sources: the Federal Register (for executive orders, anti-dumping determinations, and Section 301 modifications) and the USITC Harmonized Tariff Schedule (for rate and classification changes). Both are checked nightly.
Our pipeline runs every night. When a change is detected that affects one of your HTS codes, you'll receive an email alert the same morning — typically within hours of the change being published.
A Harmonized Tariff Schedule (HTS) code is the 8-10 digit number that determines what duty rate you pay when importing a product into the US. Every commercial import has one. You can find yours on your customs entry documents or commercial invoices.
You can upgrade anytime from the Settings page. Your catalog carries over and you'll be charged the prorated difference. Downgrade anytime too — changes take effect at the end of your billing period.
