Worked example: what a duty does to one product

Assuming the Section 232 steel (50%) rate applies to the Stainless steel water bottle (example cost $4.20, selling at $12.99), the deterministic pass-through math is:

Duty per unit

$2.10

Landed cost with duty

$6.30

Margin if absorbed

51.5%

was 67.7%

Price to hold $ margin

$15.09

+16.2%

The rate here is stated as an assumption; the Repricing tab lets you enter your own cost, price, and rate. TariffOS never sums dataset rates into a duty bill on your behalf — dollar figures come only from inputs you provide.

    USTR updates four exclusions (Chapter 99 notes 20(vvv)(i)(4)–(6) and 20(vvv)(iv)(4)) to the ten-digit statistical categories USITC introduced on July 1, 2026, keeping coverage unchanged. The November 10, 2026 expiry is unaffected.

    Court ruling / statute
    Surcharge lapses at the 150-day statutory limit

    The proclamation's own terms and Section 122's 150-day cap set expiry at July 24, 2026. A Federal Register search on August 3, 2026 found no document extending, continuing or replacing the surcharge, so it lapsed by operation of law and duties are no longer collected under it. Duties paid between February 24 and July 24, 2026 remain subject to the pending appeal of the CIT ruling. Separately, USTR's Section 301 forced-labor tariffs took effect the same day.

Deadlines to watch (next 90 days)

Refund watch

Litigation on these measures may have refund implications for duties you already paid. Discuss protective steps with your customs broker.

  • Section 122 temporary global import surcharge (10%)

    If the CIT ruling survives appeal, duties paid under the surcharge could become refundable. Importers should preserve entry records; no refund process exists while the appeal is pending.

  • IEEPA reciprocal tariffs (struck down by the Supreme Court)

    Final ruling. CBP refunds IEEPA duties with interest through the CAPE process in ACE: Phase 1 (from April 20, 2026) covers unliquidated entries and entries liquidated within the preceding 80 days; Phase 2 (from June 29, 2026) adds entries flagged for reconciliation. Finally liquidated entries beyond 80 days are not yet eligible — Phase 3 has no launch date, and the Court of International Trade is ordering reliquidation for litigants case by case. A protest cannot be filed once a CAPE declaration is accepted, so check each entry's liquidation date in ACE before choosing a route.

  • IEEPA fentanyl tariffs on China (struck down)

    Duties paid under the fentanyl tariffs are potentially refundable. Refunds run through CBP's CAPE process in ACE (Phase 1 from April 20, 2026; Phase 2 from June 29, 2026); finally liquidated entries beyond 80 days are not yet eligible.
