What Is Section 122, and Why It Replaced IEEPA Overnight?

When the Supreme Court shut down the use of IEEPA as a tariff tool, it did not remove tariffs from the policy landscape. It removed one of the more convenient ways to impose them quickly and broadly.

The response was immediate. Section 122 of the Trade Act of 1974 stepped in.

If that felt fast, it was. Trade policy rarely tolerates a vacuum. When one authority disappears, another tends to appear shortly thereafter, sometimes with all the ceremony of swapping out a flat tire on the side of the road.

To understand what happened, and what it means going forward, it helps to look closely at what Section 122 actually does, why it was used, and where it begins to show strain.

What Section 122 Actually Does

Section 122 authorizes the President to impose temporary import restrictions in response to balance of payments concerns or to prevent a significant decline in the value of the U.S. dollar. 

Those restrictions can include tariffs.

Two features define how it operates.

First, the tariff rate is capped at 15 percent. This is not an authority that allows for creative expression in rate-setting. The statute has already done the editing.

Second, the measure is temporary. Section 122 actions expire after 150 days unless Congress steps in to extend them.

That combination tells you what Section 122 was designed to be: a short-term stabilizer. Something you reach for when conditions are deteriorating and you would prefer they stop doing that.

It was not designed to carry long-term trade policy. It is more of a “buy some time” mechanism than a “solve the problem” mechanism.

Why Section 122 Was Used Immediately

Once IEEPA tariffs were invalidated, the administration lost its fastest path to imposing broad tariffs without a lengthy administrative process.

That creates a problem if your policy direction still involves tariffs.

Section 122 offers a reasonably straightforward answer.

It can be deployed quickly, without the extended investigation required under Section 301. 

It can be applied broadly, rather than being confined to a specific product or industry. And it is grounded in statute, which becomes important immediately after a court decision that places limits on how far executive authority can be stretched.

In other words, it was available, it was fast, and it came with a user manual that had already been approved.

That tends to move a tool to the front of the line.

A Tool Built for a Different Problem

Section 122 reflects the concerns of the 1970s, when balance of payments and currency stability were central economic issues.

Modern tariff policy is doing something else entirely.

Today, tariffs are often used to influence supply chains, respond to geopolitical developments, or support domestic industries. None of those objectives map neatly onto the statutory language of Section 122.

This creates a mild but persistent tension.

You have a tool designed to address one category of problem being used to address a different category of problem. It can work, in the sense that it produces tariffs. Whether it fits comfortably is a separate question.

Tools, like people, tend to perform best when used for their intended purpose.

The 150-Day Constraint

The most important feature of Section 122 is the clock, not the tariff rate.

The 150-day limit creates a defined window for action. It allows policymakers to respond without committing to a long-term position.

From a policy perspective, that flexibility is useful. It provides time to evaluate next steps, whether that involves Section 301, congressional action, or something else entirely.

From a business perspective, it introduces a different kind of complexity.

Importers are making decisions about pricing, sourcing, and contracts while knowing that the applicable tariff may change, expire, or be replaced within a matter of months. That is not an ideal planning environment, unless your business model involves guessing.

The removal of IEEPA did not eliminate uncertainty. It redistributed it into a shorter, more structured timeframe.

How Section 122 Fits with Other Tariff Authorities

It helps to view Section 122 alongside the other tools that remain in use.

Section 301 actions take longer to develop, but they are more targeted and tend to remain in place for extended periods once implemented.

Section 232 actions are tied to national security and have demonstrated a certain staying power.

Antidumping and countervailing duty measures are grounded in investigations and, when they apply, they apply with enthusiasm.

Section 122 sits at the opposite end of that spectrum. It is fast, broad, and temporary.

That makes it useful in a transition. It does not make it a long-term solution, unless the plan is to keep having transitions.

What Importers Should Take From This

It is understandable that some importers see the shift from IEEPA to Section 122 and conclude that the environment has become less risky.

That conclusion does not hold up particularly well.

The mechanism changed. The policy direction did not.

Tariffs remain a central feature of U.S. trade policy. The question is not whether they will be used, but which authority will be used next and how long the resulting measures will remain in place.

In the meantime, the fundamentals are unchanged.

Classification still determines how goods are treated under the tariff schedule.

Country of origin still drives applicability.

Antidumping and countervailing duty exposure continues to operate on its own timetable, which is not especially concerned with what Section 122 is doing.

And documentation will still be evaluated against actual business practices. This is where many otherwise impressive compliance programs begin to wobble.

A temporary tariff does not produce temporary compliance obligations. The requirements remain, regardless of which statute is currently being used to impose duties.

The Larger Pattern

Section 122 did not emerge because it is a perfect fit for modern trade policy. It emerged because it was the next available option once IEEPA was no longer usable.

That pattern is worth noting.

Trade policy often evolves through a sequence of available authorities, each with its own limitations, rather than through a single, well-aligned solution. When one option is removed, attention shifts to the next one that can accomplish something close to the same result.

From the outside, this can look improvised. From the inside, it is often a constrained set of choices being made in real time.

Section 122 is part of that sequence. It buys time, it provides coverage, and it keeps the broader policy direction intact.

What replaces it will matter more than the fact that it replaced IEEPA.

A Practical Next Step

This is the point where it makes sense to review how your products are classified, how origin is determined and documented, and how your supply chain would respond to a shift in tariff authority.
