New Section 232 Metal Tariff Rules Alter Landed Sourcing Costs
The transition to full customs value for metal tariffs raises import duties and forces complex supply chain reviews.
Aluminum Articles
Tariff Classification
Manufactured products formed from refined aluminum or its alloys represent a distinct grouping for customs valuation and import duties. These finished and semi-finished aluminum articles range from structural plates to extruded tubes, each subject to specific harmonized system codes. Border authorities verify the alloy composition to prevent tariff evasion through misclassification, using alloy chemistry tests on random samples.
The category excludes unworked ingots and primary metal blocks destined for remelting, which carry lower duty rates under standard customs schedules. Importers must track these codes because misclassification leads to severe fines and retroactively applied tariffs.
Border Compliance
Customs valuation relies on documented mill test certificates to establish the origin and grade of the metal. Shipments of aluminum articles require precise declarations of net weight alongside commercial invoices to avoid clearance delays. Importing firms must monitor anti-dumping duties that target specific extrusion profiles from designated origins.
Failure to present the correct certificate of origin results in immediate detentions or punitive bond requirements.
Market Tracking
Global logistics networks adjust to regional trade barriers by altering trade routes and supply chains. Sourcing patterns for aluminum articles depend on regional scrap availability and electricity costs. When smelters face high power tariffs, the manufacture of secondary extrusion billets shifts to countries with subsidized hydro-electric power.
These supply dynamics dictate the delivered premiums over the exchange price.
