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.

What changed in the last 7 days
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.

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. Duties paid under the program are potentially refundable — industry estimates run as high as $175 billion. Refund mechanics flow through CBP; importers should preserve entry summaries and monitor official guidance.
- IEEPA fentanyl tariffs on China (struck down)
Duties paid under the fentanyl tariffs are potentially refundable. Monitor CBP guidance.
