On a $1,000 ocean shipment: customs duty $500.00, MPF $34.58, HMF $1.25, total landed cost $1,535.83.

US duties on aluminum window frame are estimated by stacking the product's normal (MFN) tariff with the additional layers that apply to goods from Australia. In the current 2026 schedule, Steel / aluminum / copper article carries an MFN rate of 0%; Section 301 China tariffs do not apply to goods of Australia origin, though a 12.5% security base may. A Section 232 national-security rate of 50% also applies to this category (steel and aluminum 232; forced-labor base does not stack on metal content).

On top of duty, US Customs charges a Merchandise Processing Fee (MPF) of 0.3% (min $34.58, max $670.86, effective 1 October 2026) and, for ocean freight, a Harbor Maintenance Fee (HMF) of 0.1%. The ad-valorem MPF rate is unchanged; only the minimum and maximum rose for fiscal year 2027.
