Assessment and cash deposits
- Assessment instructions: no earlier than 35 days after publication, which by our count is November 9, 2026. A timely CIT summons holds liquidation until the statutory injunction window (within 90 days of publication) runs.
- Cash deposits: at the rates above for shipments entered or withdrawn for consumption on or after the date of publication of these final results. Non-reviewed firms keep the all-others rate or their most recent company-specific rate, as appropriate.
- Disclosure: calculations and analysis within five days after public announcement or, if none, within five days of publication.
CVD assessments and cash deposits are not drawback-eligible (19 U.S.C. § 1677h; see AD/CVD drawback exclusion). Ordinary customs duties on the same entries can still be drawback-eligible when merchandise is exported or destroyed, so separate CVD amounts from ordinary duty in claim math.
