Terms of service

StackTariff is operated by DevRig LLC, Wyoming, USA. By using the site you agree to these terms. This is a summary that will be expanded into the full agreement before paid plans launch.

Not customs advice (important)

Informational only — not customs advice. Classification and valuation decisions are the importer’s responsibility under 19 USC §1484. For binding rulings, file CBP Form 19; for declarations, consult a licensed customs broker.

We are not a customs broker. We do not file CBP entries, accept Power of Attorney, or communicate with CBP on your behalf, and we do not issue “official” classifications.

AI-generated suggestions

AI-generated suggestion — verify against USITC HTS before filing.

No warranty

Tariff data changes frequently. We work to keep it current and stamp each result with its as-of date, but the tools are provided “as is,” without warranty, and your import obligations are assessed by CBP at entry regardless of any figure shown here.
