What Is Actually Driving Control Component Pricing in 2026 — and Which Explanations Survive a Look at the Evidence

Executive Summary

On February 20, 2026, the Supreme Court ruled 6–3 that the emergency-powers law the White House had used to impose tariffs never gave the President that authority. The across-the-board tariffs from April 2025, and the earlier tariffs on Canada, Mexico, and China, were invalid from the day they were signed. They were never lawfully owed. The Court of International Trade has ordered Customs to refund roughly $165 billion.

Those tariffs were the stated reason for a large share of the component price increases machine builders absorbed in 2025.

The prices did not come back down. They went up faster. The federal price index for switchgear and industrial controls rose 4.1% in the three months after the ruling, against 3.2% in the three months before it. April 2026 — the first full month in which the dead tariffs were no longer being collected — produced a 3.4% jump in a single month, the largest since the tariffs were first imposed.

This brief sorts the explanations you are being handed into the ones that hold up and the ones that do not. It is built on two public records that cost nothing to check: the federal price index, and a distributor’s published log of roughly two hundred manufacturer price-increase letters going back to mid-2025. No inside information, no anonymous sources, no speculation about anyone’s motives.

The short version: three of the four drivers are real, and each has a different answer. The metals tariffs are real and have a lever most buyers have never been told about. The materials shortage is real and has no lever at all. Energy is real, but it is oil, not electricity, and it is in your conduit rather than your controller. And the fourth — the tariff that justified 2025 — no longer legally exists.

1. The Tariff That Was Never Owed

What the Court Decided

The Supreme Court held that a law letting the President “regulate” imports during an emergency does not let him tax them. Taxing is Congress’s job. That killed the April 2025 tariffs of 10% and up on goods from most countries, along with the earlier tariffs of 10% on Chinese goods, 35% on certain Canadian goods, and 25% on certain Mexican goods.

The White House replaced them within hours with a flat 10% surcharge under a different law. That replacement died too. On May 7, 2026, the trade court ruled it invalid: the order justified itself by pointing to trade deficits, and the law it leaned on requires a balance-of-payments deficit, which is a different thing Congress defined narrowly in 1974.

Two tariff programs survived both rulings, and they are the only ones that matter now: the national-security tariffs on steel, aluminum, and copper, and the older tariffs on Chinese goods.

Every legitimate tariff dollar in your panel today traces to one of those two — not to the program that justified the 2025 increases.

What This Means in Dollars

Say you bought $100,000 of imported components in mid-2025 and your supplier added a 10% tariff surcharge. That is $10,000, and it was never lawfully owed to anyone. Customs is refunding it — not to you, but to whoever imported the goods. More than 330,000 importers paid these duties across 53 million shipments, and the courts have said the refunds will take a while.

You are not entitled to that money and should not go asking for it. You are entitled to ask whether a cost that no longer exists is still sitting in your price.

2. What Two Hundred Price Letters Actually Say

One distributor publishes every manufacturer price-increase notification it receives, with the effective date, the notification date, and the manufacturer’s own stated reason. It is a public page. It is the single most useful document in this industry right now, and it is free.

Read two hundred of them in a row and three things become obvious.

First, the most common stated reason for a price increase in this industry is a phrase that means nothing. “Continued marketplace constraints” appears more than any other explanation, by a wide margin. It names no cost, no commodity, no policy, and no date. It is a placeholder where a reason should be. When your distributor forwards you one of these, you have not been told anything.

Second, the letters that do name a reason mostly name metals. Steel, aluminum, and copper appear constantly, in the letters from enclosure makers, fitting makers, connector makers, and terminal block makers. Those letters are specific, they are checkable, and they are almost all legitimate.

Third — and this is the part that matters — the letters written in late 2025 are still in force, and many of them cite tariffs that no longer exist. A tool manufacturer’s November 2025 letter itemized “global reciprocal tariffs that have increased to over 10% since July 2025.” A December 2025 letter from another cited “increased reciprocal tariffs.” A lighting supplier’s letter went further and published a table: emergency-powers tariff 20%, reciprocal tariff 125%.

Every one of those line items was ruled invalid on February 20, 2026. The price increases they justified are still on the price list.

The April 2026 Cluster

Sort the log by date and one week jumps out. Effective April 1, 2026 — six weeks after the Supreme Court ruling — a wave of increases landed simultaneously: two major control platform vendors, a fuse maker, a connector maker, a wiring device maker, an enclosure and fittings group, a drive manufacturer, and a half dozen others. More followed on April 2, April 6, and April 13.

That is what the 3.4% single-month jump in the price index is made of. It is not one company. It is the whole channel moving in the same week.

The Surcharge That Outlived Its Tariff

One letter in the log deserves its own paragraph, because it is the clearest illustration in the whole file.

A control-hardware vendor notified customers on March 31, 2026 that, because of an import tariff imposed February 25 and “expected to remain in effect for 150 days,” it would apply a temporary tariff surcharge as a separate line item on all orders beginning April 1.

That tariff was struck down on May 7.

The surcharge was a separate line item, which means it can be removed with a keystroke. Whether it was is a question worth asking, and the fact that it was itemized rather than buried is exactly why you can ask it.

3. What the Price Index Shows

The Bureau of Labor Statistics publishes a price index covering exactly your world: switchgear, switchboard, and industrial controls equipment. It updates monthly. It is free. Almost nobody in this industry looks at it, which is precisely why it is useful.

Read the last four rows together. Prices climbed faster after the tariffs died than before, and the first full month of the post-tariff world looked almost exactly like the tariff-shock month a year earlier.

That is not proof of anything on its own. April 2026 is also the month the metals tariffs were rebuilt, and the channel’s annual increases land in that window every year.

What it does establish is that removing a cost does not remove a price, and the burden of explaining the gap sits with the seller.

4. The Metals Tariffs: Two Changes That Matter

The metals tariffs were rebuilt on April 6, 2026, then rebuilt again on June 8. Any summary written between those dates is already wrong. Two changes matter to a panel builder, and one of them is an opportunity.

Use a $2,000 imported enclosure as the running example. Call it $600 worth of steel in a $2,000 box.

Change One: The Duty Now Applies to the Whole Box

The old rule taxed the metal inside the product. Duty was calculated on the $600 of steel. At 25%, that is $150.

The new rule taxes the full customs value of the product, regardless of how much metal is in it. Duty is calculated on the whole $2,000. At the same 25%, that is $500.

Nothing about the rate changed. The cost more than tripled.

This is the biggest mechanical change in the package, it took effect April 6, and it is entirely legitimate. If your enclosure vendor raised prices this spring, this is probably why.

Worth knowing: a long list of products came out of the metals tariffs on the same day — mostly things with only a little metal in them. Some of your parts got cheaper in April. Nobody sends a letter about that.

Change Two: American Metal Cuts the Rate to 10%

Here is the part that is not in the trade press.

Every category in the new structure drops to a 10% rate if the metal in the article is entirely American — steel melted and poured here, aluminum smelted and cast here, copper smelted and cast here.

Same $2,000 enclosure:

Three hundred dollars an enclosure. On the same enclosure.

And the bar just got easier to clear. Until June 8, “entirely American” meant 95% of the metal by weight. The June order lowered it to 85%.

This is not theoretical. At least one enclosure manufacturer in the distributor log has been telling customers since 2025 that it sources its steel exclusively from American mills. That vendor’s parts qualify. Its competitors’ may not. Nobody has told you which is which, because nobody in the channel is paid to.

The Rate Table, Plainly

Check the Zero-Rate Exits First

Before you compute any duty, check whether the part escapes the tariff outright. Two Customs headings do exactly that, and neither is well known.

A part outside tariff chapters 72, 73, 74, and 76 whose metal is less than 15% of its weight pays nothing. Not a reduced rate — zero, under heading 9903.82.03. You report the metal weight in kilograms as a second quantity on the entry line and the metals duty is gone. For anything that is mostly plastic, electronics, or windings inside a light steel shell, check this before anything else.

A part on the list that turns out to contain no covered metal at all also pays nothing, under heading 9903.82.01. That one was added retroactively on May 6, 2026, back to the April 6 effective date. If you paid metals duty on such a part in April, that was an overpayment.

One trap in the weight test: where a code appears in more than one part of the annex, you sum those metals. Customs’ own example is a code listed as both an aluminum and a steel derivative — add the aluminum and the steel weight, but not the copper. Do not count a metal the annex does not name for that code.

5. The Temporary 15% Is Not a 15% Rate

One category — the government’s own words are “fixed industrial machinery and power equipment” — gets temporary relief through December 31, 2027. Every summary describes this as a 15% rate. That is wrong, and budgeting from it will cost you money.

The actual rule: the metals duty is whatever it takes to bring the product’s total duty up to 15%. Not 15% on top.

Back to the $2,000 enclosure. Suppose its ordinary duty rate is 3%, or $60.

• The metals duty is not $300. It is $240 — just enough to bring the total to $300, which is 15% of $2,000.
• If the ordinary duty rate were already 16%, the metals duty would be zero. Not reduced. Zero.
• The legal basis for a large share of the 2025 increases is gone. The increases are not. The tariffs were ruled invalid from inception on February 20, and about $165 billion is being refunded. The switchgear and controls index rose 4.1% in the three months after that ruling, against 3.2% in the three months before. Letters written in late 2025 still cite those tariffs by name, and those letters are still setting prices.
• Three real drivers, three different answers. Metals tariffs got more expensive — duty now applies to the whole product — but carry a 10% rate for American metal that most buyers have never been offered. The memory and materials shortage has no lever at all and runs into 2028. Energy is real but it is oil, and it lands on your conduit and sealant, not your controller.
• The channel can make these distinctions, because some of it already does. One vendor removed a surcharge nine days after adding it. Two cancelled increases outright. Two more volunteered that their increases had nothing to do with tariffs. The standard exists. “Continued marketplace constraints” is a choice not to meet it.

That second case sets a trap.

The same logic runs one tier lower for American metal. If the metal is American, the total tops up to 10% instead of 15% — and if the ordinary duty already clears 10%, nothing is due at all.

The Trap: January 1, 2028

Here is the sharpest version of it.

Customs has a heading — 9903.82.11 — that means, in effect: this part is on the tariff list, but its ordinary duty already clears 15%, so no metals duty is due. Parts sitting in that heading pay nothing today.

That heading expires on December 31, 2027. On January 1, 2028, those goods move to a flat 25%.

Zero to twenty-five, overnight, on the parts that look cheapest right now.

The general rule is the same across the category: it loses the top-up treatment and moves to a flat 25% metals duty. Because today’s rate is a top-up and 2028’s is not, the size of the step depends entirely on the ordinary duty rate — and it is largest for the parts paying least today.

Same $2,000 enclosure, three cases:

Look at the bottom row. A part paying no metals duty at all right now — because its ordinary rate already clears 15% — gets the full 25% on New Year’s Day 2028. Its landed duty more than doubles.

That is not a forecast or a risk. It is published, it is on the calendar, and it is eighteen months out.

Two More Things for the File

If you export finished machines, duty drawback is available on some of these parts — the ones from the UK, the European Union, Japan, Korea, Mexico, and Canada, made with metal from those same countries, and not caught by anti-dumping duties. That is recoverable money.

And the old process for adding products to the metals tariffs — where companies petitioned and there was a comment period — has been abolished. Commerce and the U.S. Trade Representative can now add products to the list whenever they jointly decide to, at 25%, with no notice. There is nothing to watch. The scope can change between your quote and your ship date.

Copper deserves its own note. Refined copper traded near $6.50 a pound in early June, close to its record. Copper wire and cable costs 84% more than it did in February 2020. If you buy wire, busbar, or anything with windings in it, this is your largest exposure, and it is real.

6. The Squeeze Nobody Is Writing Letters About

Every controller, drive, panel display, and safety module in your machine contains memory chips.

In the second quarter of 2026, contract prices for standard memory rose 58 to 63% in a single quarter. Flash storage rose 70 to 75% in the same quarter. The third quarter is cooling — 13 to 18% and 10 to 15% — but cooling from a near-doubling is not relief.

The cause is not going to resolve on its own. Data centers now consume an estimated 70% of the world’s memory production. Three companies make more than 95% of it, and all three are shifting their factories toward the specialized memory that artificial intelligence chips need, because it pays better. New factory capacity does not arrive until 2027 or 2028.

The letters are starting to name it, quietly. One control platform vendor put a heading in its March 2026 customer letter that read, in effect, materials cost surge — AI data centers, and pointed at memory, semiconductors, and critical metals. A controls manufacturer’s April letter blamed “substantial increases in gold, silver, and copper costs driven by demand from AI and technology markets.” Those are two different companies describing the same thing.

This is the driver that will still be here in 2028. It has no exemption, no sourcing workaround, and no lever. And it is the one getting the least airtime.

7. Energy Is Real. It Is Oil, and It Is in Your Conduit.

If your distributor has been citing energy costs, they are not making it up. But the story is almost certainly not the one you have been told, and where it lands matters enormously.

What Happened

Military operations against Iran began February 28, 2026. On March 4, Iranian forces declared the Strait of Hormuz closed and began attacking vessels attempting passage. Crude rose roughly 35% in a week and cleared $90 a barrel. Qatar’s national energy company declared force majeure; roughly a fifth of the world’s liquefied natural gas supply went into question.

The chemical industry took the hit. Petrochemical producers across Asia declared force majeure and cut output, because more than half of their naphtha — the feedstock for plastics — comes through that strait. Polyethylene prices spiked.

Where It Lands in Your Panel

Now go back to the distributor log and look at which vendors are citing energy.

They are the conduit makers. The fittings makers. The adhesive and sealant makers. The enclosure vendors whose product is molded rather than bent. One conduit manufacturer cited “higher costs of energy, fuel, transportation, and key raw materials.” A sealant supplier’s April advisory described being eight weeks into the conflict with upstream producers under force majeure. A fittings group named “sharp increases in oil, natural gas, and diesel prices.”

Every one of those is a petroleum story. Not one of them is a control-hardware vendor, and not one of them is about the price of electricity.

The Number That Settles It

In the week after operations began, natural gas prices rose 54% in Asia and 63% in Europe.

In the United States, they rose 7%.

American manufacturing is comparatively insulated on power. Your customer’s plant is dealing with rising demand charges as data centers reshape regional load — that is a real and separate problem, and it is a genuine reason their capital plans are moving. But it is not why your drive costs more.

Energy belongs in this conversation. It belongs in the line items made from oil: conduit, fittings, wire jacket, sealant, molded enclosures. When it turns up as the explanation for a controller, ask which of the other drivers actually applies.

8. The Ones Who Did It Right

It would be easy to read this brief as an indictment of the channel. It is not, and the same public log proves why.

One test-equipment maker added a tariff surcharge in May 2025 and removed it nine days later when the underlying tariff was reduced — announcing plainly that the surcharge was gone and that the separate, ordinary price increase would remain. That is the distinction this entire brief is about, executed correctly, by a company that volunteered it.

Two manufacturers announced increases in 2025 and then cancelled them outright.

At least two others went out of their way to say what an increase was not. One wrote that its action “is not a result of any potential US government or foreign entity imposed tariffs.” Another stated flatly that its adjustment “does not include any government tariff changes.”

Those companies made the distinction unprompted. Which means every company can, and the ones that write “continued marketplace constraints” are choosing not to.

9. Four Things to Do Before Your Next Quote Cycle

1. Make them name the bucket, in writing

For each increased line, ask which of four things it is: metals tariff, China tariff, the materials and memory shortage, or ordinary price increase. Ask by email. Vendors make this exact distinction when they choose to — several did, in public, in the log. It is not an unfair question. It is just one almost nobody asks. The answer tells you which increases will ever come back down.

2. Ask every metal vendor one question

Is the steel melted and poured in the United States? Is the aluminum smelted and cast here? At 85% by weight — down from 95% as of June 8 — the part qualifies for 10% instead of 25% or 50%. On a $2,000 enclosure that is $300. This is a sourcing decision, not a negotiation, and it is available right now.

3. Watch the index yourself

The Bureau of Labor Statistics series for switchgear and industrial controls publishes monthly and is free. Ten minutes a month. When someone tells you the market moved 8%, you will know whether the market moved 8%. It is the cheapest leverage a procurement team has this year.

4. Put January 1, 2028 in your escalation language

Pull the ordinary duty rate for your imported enclosures, wireway, and power components. The lower it is, the smaller your step. If it is already at or above 15%, you are paying no metals duty today — Customs heading 9903.82.11 — and you will take the full 25% on New Year’s Day 2028. If you are quoting 2028 deliveries or holding price on a program that crosses that date, this belongs in the contract now — not in an apology later.
