Section 122 Tariffs Impose 10% Blanket Surcharge Effective February 24 — 150-Day Congressional Deadline Looms

A 10% blanket tariff surcharge took effect on February 24 under Section 122 of the Trade Act, replacing the country-specific reciprocal tariffs that the US Supreme Court struck down under the International Emergency Economic Powers Act (IEEPA). For trade compliance teams managing duty calculations, this shift in legal authority carries distinct rate ceilings and expiration timelines that directly impact how tariff data should be cached and validated.

Section 122 permits the President to impose tariffs up to 15% for a maximum of 150 days without Congressional approval. Starting from the February 24 effective date, this creates a hard deadline around late July 2025 when either Congress must authorize continuation or the surcharge expires. Teams building automated classification systems should flag this statutory limit when calculating landed costs beyond the 150-day window.

Key Distinction: Unlike IEEPA-based tariffs, which the administration had used to impose varying country-specific reciprocal rates, Section 122 applies a uniform 10% surcharge across all trading partners. This simplifies rate calculations in the short term but introduces Congressional dependency for any extension.

The immediate trade impact is already measurable. India's goods exports to the United States fell 12.88% year-on-year to $6.89 billion in February, directly reflecting the higher tariff burden. Meanwhile, US exports to India rose 36.5% over the same period, highlighting the asymmetric effects these rate changes produce on bilateral trade flows.

A pending India-US trade agreement, originally slated for signing in March, remains on hold until Washington finalizes its post-Supreme Court tariff architecture. According to Indian government officials, the deal is substantively complete but awaits the new framework so that comparative advantage calculations against competing nations remain valid. The agreement will also address Section 301 tariffs, with India named in two active investigations under that authority.

Data Accuracy Alert: The transition from IEEPA authority to Section 122 means historical rate data pulled before February 24 no longer reflects current duty obligations. Compliance systems should invalidate cached rates for all HTS codes subject to the blanket surcharge and repull current data to ensure accuracy in entry filings.

The administration has signaled intent to restore reciprocal tariffs "in another form," suggesting additional rate changes are likely once the new legal framework is established. For engineering teams, this means building flexibility into tariff APIs to handle potential mid-year rate modifications tied to either Congressional action on Section 122 extension or new executive authority.

With the 150-day clock running and bilateral agreements like the India-US deal waiting on architectural clarity, compliance systems need real-time access to authoritative HTS rate data.
