The United States' import duty structure for aluminium is multi-layered, consisting of standard tariff rates supplemented by significant trade remedy actions. Duties are primarily assessed based on the Harmonized Tariff Schedule (HTS) classification and the country of origin. Small and medium-sized importers must navigate a landscape of base duties, administrative fees, and potential punitive tariffs designed to protect domestic industries.
| Duty/Tax Type Name | Standard Rate or Rate Range |
|---|---|
| Ad Valorem | 0% to 6.5% |
| Specific Duty | Varies by weight (e.g., cents per kg) |
| Compound Duty | Combination of % and specific rates |
| Section 301 | Up to 25% (primarily for China) |
| Antidumping (AD) | Case-specific (can exceed 100%) |
| Excise Tax | Generally not applicable to raw aluminium |
| MPF (Merchandise Processing Fee) | 0.3464% (Min $32.71, Max $634.62) |
| HMF (Harbor Maintenance Fee) | 0.125% (Ocean freight only) |
Types of Duties and Taxes:
- Tariff Classifications: Standard duties include ad valorem (percentage of value), specific (fixed fee per unit), or compound (both) based on HTS codes. Many aluminium products enter duty-free under specific trade agreements.
- Trade Remedies: These include Section 301 duties on Chinese imports and Antidumping/Countervailing duties. These are applied to counteract unfair trade practices and protect the U.S. market.
- Administrative User Fees: The MPF is required for most formal entries to cover processing costs. The HMF is an additional fee specifically applied to cargo arriving via maritime transport.
