Section 122 Tariff Explained: What You Need to Know

Section 122 of the Trade Act of 1974, codified at 19 USC 2132, grants the President authority to impose a temporary surcharge on imports when the United States is experiencing a "large and serious" balance-of-payments deficit. The authority is narrow and time-limited by statute: any surcharge imposed under this provision cannot exceed 15% ad valorem (the statutory cap) and cannot remain in effect for more than 150 days. The surcharge took effect February 24, 2026, four days after the Supreme Court struck down the administration's IEEPA tariff authority (International Emergency Economic Powers Act). With its primary trade tool invalidated by the Court, the administration invoked this statutory authority as the most immediately available alternative. A presidential social media post in the days before the formal proclamation floated a 15% rate, but the controlling Federal Register notice (2026-03824, February 25, 2026) specified 10% — the rate CBP collected until the surcharge lapsed to 0% on July 24, 2026 after its 150-day limit. For covered origins a forced-labor Section 301 duty (10% or 12.5%) now backfills it. This marks only the second time Section 122 has ever been invoked. The first use was Richard Nixon's 10% surcharge in August 1971, imposed as part of the "Nixon Shock" that also suspended the gold convertibility of the dollar. Nixon's surcharge lasted four months before being lifted as part of the Smithsonian Agreement. The current surcharge's 150-day statutory limit means expiration falls on July 24, 2026, unless Congress acts to extend it or a new legal authority is established.

The Section 122 rate was 10% ad valorem while the surcharge was in force (February 24 – July 24, 2026) — applied to the declared customs value of imported goods, as a percentage of the transaction value paid to the supplier (or the appraised CBP value where transaction value was not acceptable). It lapsed to 0% on July 24, 2026 by operation of law, so there is no current Section 122 surcharge. A 15% rate was discussed via presidential social media in the days before the formal proclamation, but the controlling Federal Register notice (2026-03824, February 25, 2026) set the operational rate at 10% — the rate CBP collected for the full 150-day life of the surcharge. The 15% statutory cap was never reached via a supplemental proclamation. While it was in force, ad valorem meant the duty scaled with shipment value: a $1,000 shipment paid $150 in S122 duties, a $100,000 shipment paid $15,000, a $1,000,000 shipment paid $150,000. That proportional structure made high-value shipments especially sensitive to the S122 rate during the surcharge's life — which is exactly why its July 24, 2026 expiration mattered so much for importers of industrial machinery, capital equipment, electronics, and vehicles. Since the lapse, the calculus has shifted: for covered origins, a forced-labor Section 301 duty (10% or 12.5%, per the ~60-economy list) now backfills the old S122 line. The same $100,000 shipment now pays $0 in Section 122 duty but, if the origin is on the covered list, up to $12,500 in forced-labor Section 301 duty instead — plus MPF and any base MFN, which still applies regardless. Only shipments from the roughly 109 non-covered economies saw a genuine reduction to $0 on this tier.

The Section 122 regulations specified several categories of goods that were exempt from the surcharge while it was in force. Since the surcharge lapsed to zero on July 24, 2026 the exemption list no longer changes anyone's cost, but it remains the reference for entries filed during the February-July 2026 window. USMCA-compliant goods from Canada and Mexico were fully exempt from the surcharge. If your goods meet the rules of origin under USMCA — sufficient North American content, appropriate tariff shift, and a valid certificate of origin — they pay 0% under USMCA, and the S122 surcharge never applied to them while it was in force. This was the single most commercially significant exemption. One layer is not defeated by a USMCA preference claim: from August 19, 2026 a Section 338 retaliatory duty adds 50% on annexed non-Section-232 Canadian goods. Section 232 products are excluded. Goods already subject to Section 232 national security tariffs (steel, aluminum, copper, lumber, passenger vehicles, auto parts, and semiconductors) never paid the S122 rate while it was active, and the same exclusion flag now keeps them out of the forced-labor Section 301 duty that backfills S122 for other origins. A steel manufacturer importing hot-rolled steel at 50% S232 does not pay an additional forced-labor surcharge on top. Additional exemptions: critical minerals (cobalt, lithium, rare earths, and others under HTS Chapters 26xx), pharmaceuticals and pharmaceutical ingredients, certain agricultural goods (grains, oilseeds, and their derivatives — roughly the categories covered by the CAFTA-DR agricultural provisions), certain electronics (specific HTS subheadings designated by CBP), certain aerospace products, and passenger vehicles and parts (which are separately covered by S232). If your product falls into one of these exempt categories, your tariff calculation excludes the S122 tier. You still pay MFN duty, any applicable country-specific S301 (the China lists, or Brazil at 25%), MPF, and HMF. The exemptions reduce but do not eliminate the tariff burden.

The 150-day statutory cap was the decisive characteristic of Section 122. No matter what the administration intended or what bilateral deals were in place, Section 122 lapsed automatically on July 24, 2026 once the 150 days ran out without an act of Congress. Congress did not extend it (S.4049 was a repeal, not an extension). Instead of leaving a 0% gap, the administration used a separate authority: a forced-labor Section 301 action that took effect the same moment on ~60 economies (10%/12.5%/conditional). This is why the July 24 lapse did not translate into broad relief — for covered origins, the forced-labor duty replaced the surcharge. Bilateral deals negotiated earlier (with EU, Japan, South Korea, Taiwan, India, Vietnam, and others) persisted through the cliff — the site's per-country data reflects those rates continuing — and the forced-labor duty stacks on top for covered economies. For importers, the practical planning horizon has shifted from "when does Section 122 expire?" (answered) to "which forced-labor tier is my origin in, and is my product excluded?" Shipment timing no longer offers a Section 122 arbitrage; a one-time goods-in-transit window (entry before July 28, 2026) has closed.

While active, Section 122 occupied the middle tier of the tariff stacking formula: MFN + max(S122, S232, Bilateral) + S301. Since the July 24, 2026 lapse, S122 contributes 0 to that "max" comparison — but a new additive forced-labor Section 301 term now sits alongside it for ~60 covered economies: MFN + max(0, S232, Bilateral) + forced-labor S301 (if covered) + country-specific S301 (China lists, or Brazil 25%) + Section 338 (Canada only, on annexed non-S232 goods, from August 19, 2026). India illustrates what the middle tier looks like once it empties out. India is on the flat-10% forced-labor tier, and the 18% reciprocal country rate it used to carry was terminated by Executive Order 14389 on February 20, 2026. Section 232 does not reach most consumer goods, so nothing occupies the middle tier at all. The combined rate on a typical consumer product from India is MFN 5% + forced-labor 10% = 15%. The whole calculation is now two terms rather than three. For China, both China's own punitive S301 and the forced-labor S301 duty add on top (the D-04 double-stack). A $10,000 shipment of Chinese consumer goods (List 4A, 7.5% S301 rate): MFN ~5% ($500) + China-S301 7.5% ($750) + forced-labor S301 12.5% ($1,250) = $2,500 in duties, plus MPF $34.64 = $2,534.64 total. The total effective rate is 25.3%. For List 3 goods at 25% S301: $500 + $2,500 + $1,250 = $4,250, plus MPF = 42.8% effective rate. S232 products are excluded from the forced-labor backfill too, the same way they were excluded from S122. A $10,000 shipment of steel from Germany: S232 50% ($5,000) + MFN ~0% (steel MFN rate is low) = $5,000, plus MPF $34.64. Neither the lapsed S122 nor the forced-labor duty applies, because steel is an S232-covered product. For USMCA goods, the middle tier and the forced-labor backfill both drop out entirely. A $10,000 shipment of qualifying electronics from Mexico: 0% total tariff, plus MPF $34.64. This is the clearest illustration of why USMCA compliance has remained so commercially valuable in 2026 — the cliff didn't change it.

Section 122 charges nothing today, so the dollar question has become what replaced it. These three scenarios use the rates in force now, each computed on a $10,000 shipment. Scenario 1: $10,000 consumer electronics from Vietnam. MFN rate: 1.5% ($150). Middle tier: 0%, because consumer electronics are not Section 232-covered. Forced-labor Section 301: 12.5% ($1,250), Vietnam being on the flat tier. China-punitive S301 does not apply. Total duties: $1,400, plus MPF of $34.64 and, on an ocean shipment, HMF of $12.50. Effective rate: 14%. Scenario 2: $10,000 apparel from India. MFN rate for apparel: 12% ($1,200). Middle tier: 0%. Forced-labor Section 301: 10% ($1,000), India being on the flat-10 tier. Total duties: $2,200, plus MPF $34.64. Effective rate: 22%. Scenario 3: $10,000 furniture from China (List 3). MFN rate for furniture: 5% ($500). China-punitive Section 301: 25% ($2,500). Forced-labor Section 301: 12.5% ($1,250), which stacks on top of the punitive duty rather than replacing it. Total duties: $4,250, plus MPF $34.64. Effective rate: 42.5%. That 42.5% is the category rate and covers most furniture — metal, plastic, and non-upholstered wooden pieces. Upholstered wooden furniture and kitchen cabinets, vanities and their parts sit on a separate Section 232 wood-products tier (HTSUS 9903.76.02 and 9903.76.03) instead, carrying Free MFN of their own — a covered China shipment totals 50% rather than 42.5%. The tier applies even where a USMCA preference is properly claimed, and it is scheduled to rise to 30% on upholstered furniture and 50% on cabinets and vanities starting January 1, 2027. Two things moved these numbers in 2026, and importers routinely conflate them. The reciprocal country rates that Vietnam and India carried ended on February 20, 2026 under Executive Order 14389, four days before Section 122 was invoked at all. Section 122 then ran its own course and lapsed on July 24, 2026, and for the roughly 60 economies on the forced-labor covered list a Section 301 duty took effect the same day and backfilled it. For China, that backfill left the total slightly higher than the surcharge it replaced: 42.5% against 40% before.

The only prior use of Section 122 provides useful context for what happens next. On August 15, 1971, President Nixon imposed a 10% import surcharge under the same statutory authority, simultaneously suspending the convertibility of the dollar to gold (ending the Bretton Woods system) and imposing a 90-day wage and price freeze. Nixon's surcharge was intended as a negotiating tool to force US trading partners to revalue their currencies upward against the dollar. The Nixon surcharge lasted 122 days. It was lifted on December 23, 1971, as part of the Smithsonian Agreement, in which the major trading nations agreed to a new set of fixed exchange rates with a wider band of permitted fluctuation. The immediate effect of the surcharge's removal was a reduction in import prices and an easing of cost pressure on US manufacturers that used imported inputs. The parallel to 2026 is instructive. Like Nixon's surcharge, the current Section 122 invocation appears designed as a lever in broader trade negotiations, not as a permanent tariff policy. The bilateral deals struck with EU, Japan, South Korea, Taiwan, India, Vietnam, and others during the IEEPA period suggest the administration was pursuing a framework of country-specific agreements. The Section 122 invocation, with its statutory 150-day limit, creates a built-in deadline that concentrates negotiating pressure. The difference: Nixon operated at 10%; the current administration announced 15% but operationalized 10% under Federal Register 2026-03824. Nixon had a clear monetary objective (currency revaluation); the current administration's objectives are more diffuse (manufacturing reshoring, trade balance, revenue generation). This complexity may make a clean negotiated resolution like Smithsonian less likely.
