Section 232 Expanded: New Steel & Aluminum Derivatives from June 8, 2026
Proclamation 11032 pulls four more derivative product lines into Section 232, adds new Chapter 99 reporting codes, reduces rates on some machinery and vehicle derivatives, and lowers the US-content exemption threshold to 85%.
On June 8, 2026, CBP implemented Proclamation 11032 (CSMS #68855869), the latest adjustment to the Section 232 tariffs on steel, aluminum and copper. If you import metal products or metal-containing goods into the US, here's what moved.
Four new derivative lines are now in scope
Four HTSUS classifications that were not previously subject to Section 232 became dutiable derivatives as of June 8, 2026 — they now pay the Section 232 duty on their metal content:
- 3701.30.00 — photographic plates and film, any side over 255 mm
- 9403.20.0075 — boltless / press-fit steel shelving units
- 9403.20.0082 — steel racks
- 9403.99.9040 — parts for steel racks of 9403.20.0082
If your product falls under one of these, entries from June 8 onward carry Section 232, reported under the new Chapter 99 codes 9903.82.20 through 9903.82.26.
Some machinery and vehicle derivatives get a lower rate
The same proclamation reduced the Section 232 rate on a list of machinery and vehicle derivatives (for example, items in the 8427, 8429, 8701, 8703 and 8708 series). If you import in these categories, it's worth having your broker re-review entries dated on or after June 8 — you may be paying less than before.
The US-content exemption threshold dropped
The threshold to treat a product as "entirely of US content" — and therefore outside the metal duty — was lowered from 95% to 85%. That's a modest easing for goods with a high proportion of US-origin metal.
Rate context
For reference, current Section 232 metal duties run at 50% on base metals (Chapters 72/73/74/76) and 25% on standard finished derivatives, with reduced rates for the machinery/vehicle derivatives noted above and preferential treatment for UK and US-origin content. Russia-origin aluminum remains at 200%.
Two points worth remembering: goods subject to Section 232 are exempt from the Section 122 surcharge — the two never stack — and Section 232 is separate from any China-specific Section 301 duty, which can still apply on top.
What to do
- If you ship steel shelving, steel racks, their parts, or large-format photographic film, confirm the new Section 232 treatment applies to your entries from June 8.
- If you ship machinery or vehicle components, ask your broker whether the reduced derivative rate now applies.
- For any metal-containing product, the duty owed depends on classification and metal content — have your customs broker confirm the exact treatment before you quote a landed cost.
