Unmanned aircraft provisions reach their first effective date

The August proclamation separates complete UAS treatment from later component provisions.

Published / announced
Aug 13, 2026
Scope
Unmanned aircraft systems and specified components; scope and origin conditions require review.
Calculation coverage
Reference only. Not incorporated into the historical calculation engine.
  • September 3 is an effective date specified by the proclamation, not its publication date.
  • Separate component provisions have a February 9, 2027 effective date. Do not apply a single start date to every product.
  • Review the proclamation and annexes for covered articles, exceptions, and country treatment. These provisions are not included in the historical lookup.

HTS

USITC publishes 2026 HTS Revision 18

A new schedule edition is available from the official HTS service.

Published / announced
Sep 2, 2026
Scope
HTS schedule users; individual provisions retain their own effective dates.
Calculation coverage
Reference only. Not incorporated into the historical calculation engine.
  • Use the official schedule to inspect classification text, rate columns, units, and Chapter 99 notes.
  • A revision publication date is not a universal tariff effective date.
  • Revision 18 has not been imported into the calculation engine. Historical lookup coverage still ends April 14, 2026.

122

The original Section 122 surcharge period reaches its stated end

The February proclamation specified a temporary operative period ending July 24.

Published / announced
Feb 20, 2026
Scope
Historical surcharge treatment; this record does not resolve subsequent actions or litigation.
Calculation coverage
Reference only. Not incorporated into the historical calculation engine.
  • Use the entry date and governing provision rather than treating Section 122 as an indefinitely active surcharge.
  • Check later official actions and court orders before drawing a current-duty conclusion. This is a record of the original period, not a complete subsequent-law review.

301

A separate Section 301 action covers 60 economies

USTR describes country-dependent rates of 10% or 12.5%, with product exceptions.

Published / announced
Jul 23, 2026
Scope
Listed trading partners and covered goods under the July notice, not just China.
Calculation coverage
Reference only. Not incorporated into the historical calculation engine.
  • The implementing notice specifies entry treatment beginning at 12:01 a.m. Eastern on July 24, subject to its transition provisions.
  • The fact sheet identifies exceptions including articles subject to Section 232. Consult the implementing annexes for the actual product and country mapping.
  • This action is distinct from the earlier China technology-transfer actions. Do not assume the same exclusions or stacking treatment applies to every Section 301 action.

Interest

Third-quarter overpayment rates return to 7% / 6%

The published table distinguishes non-corporate and corporate overpayments.

Published / announced
See source publication
Scope
Interest estimates; entitlement and accrual dates still require customs-specific review.
Calculation coverage
Included in the quarterly interest table; accrual assumptions still apply.
  • The Q3 rates are 7% for non-corporate and 6% for corporate overpayments, compared with 6% and 5% in Q2.
  • The estimator applies rates to their respective quarterly periods, not retroactively to the entire interval.
  • The interest table is updated through Q4 2026. Missing later quarters are not silently projected.

IEEPA

CAPE adds a defined reconciliation-entry pathway

The update covers specified flagged entries with no reconciliation entry on file.

Published / announced
Jun 23, 2026
Scope
Entry types 01, 02 and 06 flagged for reconciliation, subject to the bulletin conditions.
Calculation coverage
Reference only. Not incorporated into the historical calculation engine.
  • The June update retains Phase 1 filing requirements and limits the pathway to unliquidated entries and entries within 80 days of liquidation.
  • Entries with the reconciliation entry already on file are outside this deployment. A reconciliation flag alone does not determine the result.
  • Read the latest CBP instructions before filing; TariffLab does not connect to ACE or determine live CAPE acceptance.

IEEPA

CAPE Phase 1 begins within ACE

CBP establishes a declaration and validation workflow for IEEPA duty refunds.

Published / announced
Apr 13, 2026
Scope
Eligible IEEPA entries across affected origins; TariffLab calculations remain China-specific.
Calculation coverage
Reference only. Not incorporated into the historical calculation engine.
  • The April instructions specify a CSV of entry numbers only, up to 9,999 per declaration, submitted by the importer of record or the filing broker.
  • ACE performs file and entry validations. A TariffLab estimate is neither an accepted declaration nor an approved refund.
  • CBP directs filers not to initiate an IEEPA refund by Post-Summary Correction. Consult the bulletin and subsequent updates for procedural requirements.

Interest

Second-quarter overpayment interest rates decrease

Q2 uses 6% non-corporate and 5% corporate overpayment rates.

Published / announced
See source publication
Scope
April 1 through June 30, 2026 rate period.
Calculation coverage
Included in the quarterly interest table; accrual assumptions still apply.
  • Do not carry the Q1 rates of 7% and 6% through this quarter.
  • Quarter boundaries are segmented explicitly in the calculation. Actual deposit and liquidation or reliquidation dates matter.
