Program	Heading	Rate	Amount

Section 301 China (List 3)		25%	$2,500.00
Section 232 Aluminum As of April 6, 2026, CBP may assess Section 232 metals duties based on US sales price rather than declared customs value.		50%	$5,000.00
Antidumping / countervailing duty (Aluminum Extrusions) AD 86.01% + CVD 7.37%. Scope is set by Commerce's written product description and rates are exporter-specific, so this is a worst-case ceiling. A-570-967	A-570-967	93.38%	$9,338.00

Notes for this line

Section 301 China tariff (List 3) adds 25% to this product.
Section 232 Aluminum tariff adds 50%.
Antidumping/Countervailing Duty (A-570-967) adds 93.38% (AD 86.01% + CVD 7.37%) for Aluminum Extrusions.
AD/CVD applies by written product scope, not by HTS code — the HTS numbers in a Commerce order are listed for convenience only. Finished goods assembled from covered inputs are often excluded, and rates are exporter-specific, so the figure above is a worst-case ceiling. Confirm your scope and your supplier's cash-deposit rate with your customs broker before relying on it.
Section 301 forced labor does not apply to this line: Exempt: article is already subject to Section 232 duties (9903.05.90, U.S. note 52).
