On August 4, 2026 the Bureau of Industry and Security (BIS) published a notice seeking public comments on expanding tariffs applicable to certain steel, aluminum and copper derivative products under Section 232 of the Trade Expansion Act of 1962 (Section 232) to fourteen (14) additional derivative products.
The list of products proposed to be subject to additional tariffs include:
- Aluminum powder of a non-lamellar structure (HTSUS 7603.10.0000)
- Brass-wind musical instruments and parts and accessories thereof (HTSUS 9205.10.0000 and 9209.99.4080)
- Parts of welding machines and apparatus (HTSUS 8515.90.2000)
- Free-standing floor safes classifiable in HTSUS 8303.00.0000
- Electric conductor cables (HTSUS 8544.49.2000, 8544.49.3040, 8544.49.3080, and 8544.60.4000)
- Fire extinguishers (HTSUS 8424.10.0000)
- Parts of heat exchange units (HTSUS 8419.90.3000)
- Parts of linear acting hydraulic power engines and motors (HTSUS 8412.90.9005)
- Mobile lifting frames on tires and straddle carriers (HTSUS 8426.12.0000)
- Other self-propelled cranes and mobile lifting frames (HTSUS 8426.41.0090)
- Tanker trailers and tanker semi-trailers (HTSUS 8716.31.00)
- Self-loading or self-unloading trailers and semi-trailers for agricultural purposes (HTSUS 8716.20.00)
- Other trailers and semi-trailers (HTSUS 8716.40.00)
- Filled steel containers of the following chemicals and related items:
- Propane, liquefied, other than minimum purity of 90 liquid volume percent (HTSUS 2711.12.0020)
- Oxygen (HTSUS 2804.40.0000)
- Propene (propylene) (HTSUS 2901.22.0000)
If implemented, a majority of the listed products would be subject to a duty rate of 25% ad valorem on the value of the product. However, self-loading or self-unloading trailers and semi-trailers for agricultural purposes would generally be subject to the 15% tariff outlined in clause (5) of Proclamation 11021 dated April 2, 2026 because it is a type of agricultural equipment. On the other hand, filled steel containers and related items for the above-specified chemicals would generally be subject to the 50 percent tariff outlined in clause (2) of Proclamation 11021, because those containers – when imported unfilled – are subject to the same tariff rate; this tariff would only apply to the value of the metal container and would not apply to the value of a filled container’s contents.
BIS is seeking comments and information on the following: (i) the aluminum, steel, and/or copper intensity of these products, (ii) whether imports of the products are of such volume as to undermine national security, (iii) the extent to which domestic production of the products can meet domestic demand, (iv) the effect on the economy, including domestic industry, if the products are included as derivative articles, and (v) any other relevant factors.
Comments are due by August 27, 2026 and may be submitted to the Federal rulemaking portal at: www.regulations.gov. The regulations.gov ID for the notice is BIS-2026-0331.
