Key Takeaways

• The Rule Flipped on April 6: Section 232 duties on steel, aluminum, and copper derivative articles now apply to the full customs value of the imported product, not just the metal content.
• A 20-Fold Multiplier on a Premium Imported Washer: A $2,000 imported residential washer with $50 of declared steel content used to pay roughly $25 in Section 232 duty (50 percent on metal content). The same washer now pays $500 (25 percent on full customs value). The rate dropped, but the base ballooned. Lower-priced or higher-metal-share washers see smaller multipliers, closer to ten-fold.
• The 15-Percent Cliff: Annex IV exempts products with applicable metal content under 15 percent of total weight, but only if they are not classified in HTSUS Chapters 72, 73, 74, or 76. Engineers are about to redesign appliances to land at 14.9 percent.
• The Loophole That Killed a Missouri Nail Plant Just Got Closed: In 2018, the same Section 232 statute hurt a domestic nail maker when finished imports escaped duty. The April 2026 proclamation closes that gap. It also opens new ones.

The April 6 Rule That Multiplied Your Appliance Bill

On April 2, 2026, the White House signed a proclamation titled “Strengthening Actions Taken to Adjust Imports of Aluminum, Steel, and Copper Into the United States.” It went into effect at 12:01 a.m. eastern daylight time on April 6, 2026, twenty-six days ago. The text runs many pages of trade-lawyer prose. The economically explosive sentence is one clause long.

The Section 232 ad valorem duty on steel, aluminum, and copper derivative articles “shall apply to the full customs value of the imported product, regardless of metal content.”

That single phrase rewrote the math on roughly every imported product containing a meaningful share of the three covered metals. Primary metal articles continue to face 50 percent. Most finished derivatives, including washing machines, dishwashers, fasteners, electrical fittings, and HVAC components, now face a 25 percent rate set by the secondary derivatives annex, applied to their full customs value rather than the metal portion alone. The shift in the base is the story. The percentage now multiplies a much bigger dollar amount.

Under the prior framework, an importer of a finished derivative article reported the steel content separately on the customs entry. Section 232 duty applied only to that declared metal value. The non-metal portion paid its standard most-favored-nation rate. Importers who could plausibly argue that 95 percent of a washing machine’s value was electronics, motors, plastic, glass, and software had a real way to limit Section 232 exposure to the actual steel.

Now the 25 percent applies to the full landed cost. Every dollar of that washer, including the inverter board, the drum bearings, the LCD, the recycled-content plastic, and the freight, sits inside the Section 232 base.

The Math, With Real Numbers

Take a $2,000 imported premium residential washer from a brand without a US plant for that model. This is not the median US washer (those run $700 to $1,500) but a high-end front-loader where most of the bill of materials is electronics, motor, and plastic. Assume $50 of declared steel content, about 2.5 percent of the customs value.

Old Section 232 math:

$\text{Duty} = 50\% \times \$50 = \$25$

The 50 percent rate took effect in June 2025 and applied only to the declared metal content.

New Section 232 math:

$\text{Duty} = 25\% \times \$2{,}000 = \$500$

The rate dropped from 50 percent to 25 percent. The duty went up twentyfold.

The arithmetic is not a trick. The old rule taxed a small slice of the customs value at a high percentage. The new rule taxes the entire customs value at a lower percentage. When the metal-content slice is thin, as in washers, dishwashers, ranges, refrigerators, e-bikes, and escooters where the bill of materials is dominated by motors and electronics, the multiplier is enormous. When the slice is fat, as in cast-iron skillets, steel shelving, and plain fittings, the multiplier collapses toward unity, and at the 25 percent secondary-derivatives rate it can even land below one (a duty decrease).

That asymmetry determines who got hit hardest. Premium imported appliances with high engineered content take the heaviest beating. Goods that are mostly metal by value barely move, and a few may even pay less.

The 15 Percent Cliff Buried in Annex IV

The proclamation’s underreported feature is the escape hatch. Section 232 duties “generally apply only if the combined weight of aluminum, steel, and copper used in the article is at least 15 percent of the article’s total weight.” The threshold sits in Annex IV. It applies to derivative products not classified in HTSUS Chapters 72 (steel), 73 (articles of iron or steel), 74 (copper), or 76 (aluminum).

The test is weight-based, not value-based. That distinction is not academic. It is the entire ballgame.

A small electronic device, say, a plastic-bodied portable speaker, might be 5 percent steel by weight and 25 percent steel by value. So long as its combined steel, aluminum, and copper weight stays below 15 percent, it is exempt. A larger machine that crosses 15 percent combined-metal weight pays 25 to 50 percent on its full customs value. The cliff is sharp. The wrong side of it is expensive.

What happens at a sharp threshold buried in a tariff schedule is what always happens. Engineering responds. Product teams are already in budget meetings asking how much steel can come out before the next product cycle ships. Manufacturers will substitute aluminum (also tariffed), composites, plastic, and titanium where they can, redesigning for the regulatory cliff rather than the engineering optimum. The internal frame of a 2027 imported dishwasher is going to weigh exactly enough less than its 2025 predecessor to land at 14.9 percent metal by weight, and the bracket that gets removed is going to be the one nobody on the outside notices.

This is the predictable behavior of optimization under a discontinuous tax. Smoot-Hawley raised tariffs on more than 20,000 goods in 1930 using fine-grained product classifications, and the resulting classification disputes consumed customs courts for years.

The Loophole the Last Round Created, and This Round Closed

The April 6 rule is not arbitrary. It closes a real exploit, and the case study sits in Poplar Bluff, Missouri.

When the original Section 232 tariffs took effect on June 1, 2018, they applied to raw steel and aluminum, not to finished goods. Mid-Continent Nail Corporation, then a leading domestic nail manufacturer, ran a plant that bought tariffed steel and competed with imported nails from China, Taiwan, Turkey, and India that were not subject to Section 232 duties. Within two weeks, the company’s June sales fell by half. Customers cancelled because they could buy duty-free imported nails for less. The plant laid off more than 100 workers in two weeks and lost roughly 200 employees and 70 percent of its sales before the company won a tariff exemption from the Department of Commerce on April 3, 2019.

That gap is what the April 2026 proclamation addresses. A domestic finisher of metal goods could not be undercut by a foreign finisher who paid no Section 232 duty on the assembled product. Whirlpool, which still operates US plants, raised concerns with the White House and Customs and Border Protection in August 2025, alleging that Samsung and LG had been deliberately lowballing transfer prices on units shipped from Korea to reduce their Section 232 exposure. The April 6 rule eliminates the metal-content carve-out outright. It does not directly stop transfer-price manipulation, since importers can still declare a lower customs value, but it removes the legal architecture that made carve-out gaming possible in the first place.

The price for closing those exploits is a 20-fold duty increase on a residential washer that competing US plants, including the Samsung facility in South Carolina, the LG facility in Tennessee, and Whirlpool’s domestic footprint, cannot fully replace at current capacity. The duty is real. The substitute supply is not yet there. The gap gets filled by the consumer.

What the Lawsuits Get Right

The legal exposure on this proclamation is not zero, but it is smaller than the exposure on the IEEPA tariffs that the Supreme Court struck down in February 2026. Section 232 sits on a different statute, the Trade Expansion Act of 1962, and rests on a national-security finding that has historically been treated deferentially by the Federal Circuit. Pending suits like Express Fasteners v. United States, filed in the US Court of International Trade on January 27, 2026, contest specific applications of the duty rather than the underlying authority. They are unlikely to vacate the rule. They are likely to chip at how it gets implemented at the port of entry.

Importers should not plan around a fast judicial reversal. The full-customs-value framework is the operating environment for the foreseeable future.

What Comes Next

Three things are going to play out in the rest of 2026 and into 2027.

Consumer prices come on a lag. Retail appliance pricing absorbs cost increases over roughly two to four months as retailers cycle through pre-tariff inventory before raising shelf prices. The visible spike will land in late summer 2026 and a second leg arrives in early 2027 as the next wave of post-tariff stock works through. The duty does not arrive at the showroom on April 6. It arrives in August.

The design cliff comes second. Every imported product team currently between product generations is going to ship its 2027 refresh with a slightly lower steel weight ratio than its 2025 predecessor. The threshold to beat is 15 percent by weight, and that is the number that ends up in design briefs. Reading product reviews from 2027 onward, watch for the words “lighter chassis,” “polymer frame,” or “reinforced composite” attached to imported appliances. That is not a marketing tagline. That is Annex IV.

The redirection of trade flows comes third. Manufacturers with US capacity, including Whirlpool domestically, Samsung in South Carolina, and LG in Tennessee, gain a 25-to-50-percent moat on the imported portion of the market. Foreign producers without US plants will rebadge through third countries that have negotiated bilateral exemptions, accelerate licensing deals with US contract manufacturers, or eat the duty for a quarter while they figure out a more permanent answer. Expect a major Asian appliance brand to announce a new US plant or joint venture before the end of 2026. The plant will not produce a unit until 2028. The duty bill in the meantime will run into the billions.

The clearest historical lesson is that broadly applied tariffs on commodity inputs, even ones that close real loopholes, are crude weapons. The 2018 Section 232 round nearly destroyed a Missouri nail plant that nobody on the policy side had been thinking about until the layoffs hit. The April 2026 round will surface something equally specific that nobody is thinking about as of May 2026. The 15-percent weight threshold is a likely candidate. Find out which mid-sized manufacturer is right now redesigning a product to land at exactly 14.9 percent steel by weight, and you will be looking at the next Mid-Continent Nail story before it happens.

The other thing nobody told the consumer is that the duty has already been paid. Every shipping container of imported appliances unloaded at Long Beach on April 6 walked into a tariff bill twenty times higher than the one it was budgeted against. Those containers have not yet hit retail. When they do, the difference between the old sticker price and the new one will be roughly equal to a small piece of steel, multiplied by the entire rest of the machine.
