After 20 years in the trade industry, I can honestly say that filing a customs entry has never been this challenging—or costly.
The recent changes to the United States’ steel and aluminium tariffs, known as Section 232 rules, have created a complex landscape for global trade.
The 25% tariff rate now applies universally, demanding industries adapt to avoid significant penalties and optimise their duty and tax obligations.
Key changes with Section 232 rules
- All countries, including those previously exempt, now face the 25% tariff.
- Expanded requirements for declaring the value of derivative products.
- No drawbacks allowed.
These revised tariffs are in addition to any main or preferential duty rates and other tariffs implemented since the Trump Administration’s second term. This means that even a simple import has become a labyrinth of HS codes for a single commodity.
Take, for example, a fry pan: historically, it had a single classification of 7615.10.3025, and duty was paid on the total value. Now, I must determine if Section 301 or IEEPA tariffs apply, assess any aluminium content for Section 232, split the values between two entry lines on my customs declaration, and pay duty for each applicable tariff.

Industries are struggling to manage the complexity needed to report derivative values accurately. They risk paying the full 25% without the correct derivative value or face maximum penalties for incorrect classification, with no mitigating factors considered by CBP.
Which industries are impacted?
- Automotive industry: Must report steel content in components like bumpers and body stampings. Derivative products such as aluminium bumpers are affected.
- Construction industry: Uses flat-rolled products, bars, rods, angles, shapes, sections, and sheet piling. Aluminium structures and frames are subject to tariffs.
- Manufacturing and machinery: Bars, rods, and wires used in machinery. Aluminium wire, rods, and tubes are used in electrical and plumbing applications.
- Infrastructure and transport: Rails and plates for railway construction. Tubes, pipes, and hollow profiles for plumbing, oil, and gas transport.
- Appliances and household goods: Stainless steel products for kitchenware. Aluminum cookware and utensils are affected.
- Agricultural equipment: Derivative products like nails and staples used in manufacturing.
