What the current US beta can calculate
- Deterministic general HTS rates supported by the bundled USITC release.
- FY2026 formal-entry Merchandise Processing Fee when formal entry is explicitly selected.
- Harbor Maintenance Fee when covered commercial-vessel cargo is explicitly confirmed.
- Supported China Section 301 duties when the ordinary HTS line explicitly references a deterministic Chapter 99 heading.
- The locked China-origin primary-steel Annex I-A Section 232 family under 9903.82.02, limited to complete 10-digit descendants of the 39 published prefixes in the Phase 25 contract.
What remains outside automatic coverage
Other Section 232 families or origins, Section 122, antidumping and
countervailing duties, safeguards, quotas, excise taxes, special entry
fees, preference eligibility, Chapter 98 treatment and
description-specific exclusions may change the amount. An uncovered or
ambiguous condition is flagged for review instead of silently treated
as zero.
Your inputs determine the result
The service does not determine a legally binding classification,
origin or customs value. Verify that shipping and insurance are not
counted twice, that the complete 10-digit statistical code is used
where required, and that the selected date matches the intended entry
or withdrawal date.
Dates and data releases matter
The beta calculates only dates covered by an installed published
schedule and does not calculate future entry dates. A saved result
preserves its source version; it does not update automatically when
official rules change.
Support does not convert an estimate into advice
Product-support, correction, pilot or commercial conversations can
explain TariffCalc behavior and record a concern, but they do not
create a customs-broker, legal, tax or filing-advisory relationship.
Internal validation is not professional sign-off
TariffCalc validates source checksums, deterministic formulas, live
official-data cases and fail-closed behavior internally. The beta does
not claim an external customs-professional approval. For a material
shipment, unusual facts or an actual filing, consult a licensed customs
broker, qualified trade professional or the responsible authority.
Do not file from the total alone
Review the displayed HTS line, Chapter 99 headings, formulas, warnings,
fee assumptions, effective date and official sources before acting.
