Short answer: Section 232 duties on steel and aluminum apply to far more than raw metal: they reach derivative products from cookware to furniture frames to fitness equipment, and they stack on top of regular Most Favored Nation duties and any Section 301 tariffs already on the goods. For DTC brands, the exposure hides in product components and packaging that nobody classified as steel or aluminum products. The fix is mapping the exposure SKU by SKU, then deciding deliberately whether to absorb, reprice, or re-source.
What Section 232 actually covers
Section 232 duties were imposed on national security grounds and apply to steel and aluminum articles and an expanding list of derivative products. The key point for DTC brands is that the duties follow the material, not the industry. A water bottle, a patio chair, a set of dumbbells, or a kitchen knife set can all carry 232 exposure if the steel or aluminum content triggers the classification.
The derivative product lists have grown over time, pulling in finished goods that brands never thought of as metal products. Each expansion catches a new set of SKUs by surprise, which is why a classification review from two years ago is not sufficient today.
Country exemptions and quota arrangements change the math without changing the principle. Some origins face the full duty, some have quota-based relief, and the landscape shifts with trade negotiations. The only stable approach is monitoring the exposure continuously, not assuming a past answer still holds.
How the duties stack
Section 232 duties apply on top of everything else. A product that already carries a 25 percent Section 301 tariff and a 5 percent MFN rate can pick up an additional 232 duty on the steel or aluminum portion, and the total landed cost jumps in a way that no single tariff explains. Brands that model tariffs one at a time miss the stacking.
The stacking applies at the component level too. A product classified under a non-metal HS code can still attract 232 duties on its metal components if the rules for that product line say so. The classification of the finished good does not always settle the question.
This is where landed-cost models break. A model that applies one duty rate per SKU will understate the cost of every product with 232 exposure, and the variance shows up as unexplained margin erosion that nobody can attribute until someone audits the tariff stack.
Finding your exposure
Start with a bill-of-materials review for every SKU: what metals are in the product, the packaging, and the components. Most DTC brands have never asked their suppliers this question systematically, and the answers are often surprising.
Then map each metal-containing SKU against the current 232 product lists and the applicable duty rates by country of origin. This is a classification exercise, and for high-volume SKUs it is worth getting a professional opinion rather than guessing. A wrong guess in either direction costs money.
Prioritize by spend. Rank SKUs by the dollar value of potential 232 duty, and work the list from the top. A handful of SKUs usually account for most of the exposure, and those deserve binding rulings and active monitoring.
Your options once you know
Absorb, reprice, re-source, or redesign. Absorbing works when the exposure is small and the product is strategic. Repricing works when the whole category faces the same duties and competitors must move too. Re-sourcing to a lower-duty origin works when the supply chain allows it, but verify the origin rules carefully. Redesigning away from the metal works when the product allows it, and is the only permanent fix.
Whatever you choose, choose it deliberately and document it. The brands that get hurt are the ones that never made a decision and let the duties accumulate as unexplained cost.
Do Section 232 duties apply to products already covered by Section 301?
Yes, they stack. Section 301 and Section 232 are separate authorities addressing different concerns, and both can apply to the same shipment. Always model the full stack, not each tariff in isolation.
Can we get an exclusion for our specific product?
Exclusion processes have existed for 232 duties, with varying availability over time. They are product-specific, time-limited, and require a real application. If your exposure is large, it is worth investigating, but do not plan the business around an exclusion you do not have.
How often should we re-check 232 exposure?
Quarterly at minimum, and immediately when product lists expand or origin arrangements change. The lists have grown repeatedly, and each expansion is effectively a new tariff on whoever was just added.
