A fresh layer of trade-policy risk just landed on importers, and China-linked supply chains are among the first to feel it. After the U.S. Supreme Court struck down a prior tariff program that had been imposed under the International Emergency Economic Powers Act, the White House moved to replace it with a new, time-limited structure.
The replacement is a temporary, across-the-board import surcharge implemented under Section 122 of the Trade Act of 1974. The President’s proclamation sets an additional 10% ad valorem duty on most imported articles, effective at 12:01 a.m. Eastern on February 24, 2026, and designed to last for 150 days unless Congress extends it. U.S. Customs and Border Protection (CBP) issued operational guidance confirming it applies to imported articles “of every country” unless specifically exempt.
Who Pays, In Real Terms
At the border, the importer of record is the party responsible for declaring the goods and paying duties. In other words, even if suppliers, brokers, or logistics partners are involved, the company whose name sits on the entry is typically the one absorbing the immediate cash impact. This is why tariff changes often show up first as a working-capital squeeze, and only later as a pricing update or renegotiated contract term.
The 10% surcharge matters because it changes the total “landed cost” calculation that procurement teams use to price products and forecast margin. If a shipment has a customs value of $100,000, the surcharge alone can add $10,000 before other duties, fees, freight, and insurance. In categories where margins are thin—private-label consumer goods, accessories, home products, and fast-moving retail SKUs—this can quickly turn a profitable item into a break-even one.
Why China-Linked Supply Chains Feel Disproportionate Pressure
Many businesses describe their exposure as “China-linked” even when final assembly happens elsewhere. That’s because the supply chain still depends on China-origin inputs, tooling, subassemblies, or upstream manufacturers. When tariff policy shifts abruptly, scrutiny often rises around documentation, classification, and origin claims, making operational discipline just as important as cost control. CBP’s guidance also highlights compliance mechanics that can affect planning, including rules around foreign-trade zones and the availability of drawback for the additional duties.
The 150-Day Clock And The Risk Of A Higher Rate
Section 122 allows a temporary surcharge for up to 150 days, and the proclamation notes the statute permits up to 15% in these circumstances. Reporting around the rollout indicates the administration has been considering an increase from 10% to 15%, creating a moving target for importers trying to set pricing and inventory strategy.
That timeline creates a strategy problem, not just a cost problem. Overreacting can trigger rushed supplier changes, quality issues, and higher long-term costs. Underreacting can leave companies eating margin for a full quarter if the duty stays in place or rises.
As Ryan Stallard, an International Business Development Consultant, put it: “When tariffs shift quickly, purchasers become more selective and the suppliers positioned to be trustworthy, easy to communicate with, and safer choices often gain more market share.”
What To Watch Next
For now, the immediate playbook is straightforward: update landed-cost models, validate who holds duty liability under your incoterms and contracts, tighten classification and origin documentation, and run scenarios for both a short-lived 10% surcharge and a potential step-up in rate. The most resilient importers will treat this moment as a test of speed and operational rigor, not just a debate about policy.
