What Happens When Section 122 Expires July 2026

Section 122 of the Trade Act of 1974 (19 USC 2132) caps any surcharge imposed under its authority at 150 days. The current Section 122 surcharge took effect February 24, 2026. Counting 150 days forward: the surcharge expires on July 24, 2026. The expiration is automatic by statute. No congressional vote, no executive action, and no court ruling is needed to trigger it — July 24, 2026 arrives, and Section 122 authority lapses. The administration cannot administratively extend the 150-day limit. If the surcharge is to continue beyond that date, Congress must pass legislation, or the administration must invoke a different legal authority. The significance of this date cannot be overstated for importers. Section 122 is currently the largest single component of tariff costs for most non-China, non-S232 goods. For a company importing $500,000 per month in electronics from Vietnam at a total effective rate of 21-23%, S122 represents roughly $90,000/month in duties — $1,080,000 annually. If the surcharge expires as scheduled, that $90,000/month cost disappears overnight. The ExpirationCountdown tool on every CalcMyTariff.com page shows the exact time remaining until July 24, 2026. Use this alongside the What-If toggle to see your current tariff cost versus your post-expiration projected cost for any country-product combination.

When Section 122 expires on July 24, 2026, the tariff stacking formula changes from: MFN + max(S122, S232, Bilateral) + S301 to: MFN + max(0, S232, Bilateral) + S301. For goods subject to S232 (steel, aluminum, copper, lumber, autos, semiconductors): no change. S232 is permanent and does not interact with S122. Steel remains at 50%, aluminum at 50%, autos at 25%. For goods from China: Section 301 continues indefinitely. Post-S122, Chinese goods face MFN + S301 = typically 10-30% for most products, down from 20-45% currently. A Chinese electronics accessory (List 4A, 7.5% S301) goes from MFN 3.4% + S122 15% + S301 7.5% = 25.9% down to MFN 3.4% + S301 7.5% = 10.9%. For bilateral deal countries (EU, Japan, South Korea, Taiwan, India, Vietnam): the situation is legally uncertain. Bilateral deals were negotiated under IEEPA authority — which the Supreme Court struck down. After S122 expires, what rate applies? Options: (a) the bilateral deal rate continues as a voluntary commitment by the foreign party, (b) the rate drops to MFN only with no surcharge, or (c) the administration imposes a new authority. No court or legal authority has resolved this. Model both scenarios: post-S122 rate equals the bilateral deal rate, or post-S122 rate equals MFN only. For all other countries (no S232, no China, no bilateral deal): post-S122, goods face MFN only. For a country at standard S122 15% with MFN 5%, the rate drops from 20% to 5% — a 75% reduction in the tariff burden.

The dollar impact of Section 122 expiration is straightforward to calculate: S122 rate (15%) × your monthly customs value = monthly savings after expiration. Scenario 1: $50,000/month in consumer goods from Vietnam. Current rate: 5% MFN + 18% bilateral = 23%. Duties: $11,500/month. Post-expiration (assuming bilateral rate drops to MFN only): 5% MFN. Duties: $2,500/month. Savings: $9,000/month, $108,000/year. Scenario 2: $200,000/month in electronics from Germany. Current rate: 3.4% MFN + 15% bilateral = 18.4%. Duties: $36,800/month. Post-expiration (bilateral collapses to MFN): 3.4%. Duties: $6,800/month. Savings: $30,000/month, $360,000/year. Scenario 3: $100,000/month in furniture from China (List 3, 25% S301). Current rate: 5% + 15% + 25% = 45%. Duties: $45,000/month. Post-expiration (S301 continues, no S122): 5% + 25% = 30%. Duties: $30,000/month. Savings: $15,000/month, $180,000/year. (China still expensive, but meaningfully less so.) Scenario 4: $75,000/month in steel from Germany. Current rate: 50% S232. Post-expiration: 50% S232 (unchanged). Savings: $0. S232 is permanent.

The Section 122 expiration creates a timing optimization opportunity for importers with flexible order cycles. The strategy: delay shipments where possible to arrive after July 24, 2026, saving the 15% S122 rate on that inventory. Lead time considerations: ocean freight from China or Southeast Asia takes approximately 28-35 days. Air freight takes 3-7 days. A shipment ordered July 1 from Vietnam by ocean freight arrives approximately August 5 — after the July 24 expiration. A shipment ordered June 1 arrives around July 6 — before expiration. For high-value, low-perishability goods (electronics, machinery, industrial components, furniture), delaying a June order to early July or late June could save significant money. A $500,000 container delayed by 30 days saves 15% × $500,000 = $75,000 in S122 duties — worth more than the cost of a month's inventory carrying cost for most businesses. The risk: the administration may invoke new tariff authority on or before July 24 that reinstates rates equal to or higher than S122. If Congress acts to extend Section 122, or if a new executive action takes effect the same day S122 lapses, the anticipated savings may not materialize. Importers should model the timing strategy conservatively, accounting for the possibility that new authority replaces S122. A balanced approach: for goods with 60+ day lead times (ordered today, arriving after July 24), factor in the lower post-expiration rate as a scenario. For goods with shorter lead times, the decision to delay must weigh inventory risk against tariff savings.

Section 122 expiration gives US importers negotiating leverage with suppliers — and also creates a pricing reset that suppliers may try to exploit in the other direction. The positive leverage: if you have been paying your supplier a price that implicitly absorbed the Section 122 tariff increase, you have grounds to renegotiate post-expiration. Many supply contracts were renegotiated upward in early 2026 when S122 took effect. The expiration is an opportunity to reduce landed cost by either lowering the supplier price or taking advantage of the lower-tariff cost structure. The risk from suppliers: foreign suppliers are aware that US importers will face lower tariff costs after July 24. Some may anticipate this and raise their prices, partially capturing the tariff windfall. A Vietnamese supplier currently selling at $10/unit FOB may raise to $11.50/unit on the theory that the US importer's landed cost stays roughly the same even with the 15% S122 removal. Negotiating strategy: do not reveal your tariff calculation or the magnitude of your expected savings in supplier negotiations. Frame any price discussions around market conditions, order volume commitments, and payment terms rather than tariff cost structures. If your supplier raises prices to capture tariff savings, consider whether alternative sourcing countries or US domestic production offer better economics. Inventory planning: if you maintain safety stock, consider running down inventory levels in June and early July (buying less at current tariff rates) then restocking in late July and August at lower rates. This requires careful coordination with your supplier on order timing, minimum order quantities, and shipping schedules.

The 150-day statutory limit is clear, but the political reality is that the administration may not want to simply accept a 15-percentage-point tariff reduction on July 24 without a plan. Several replacement scenarios are being discussed as of March 2026. Congressional extension: the administration could request Congress to pass legislation extending Section 122 authority beyond 150 days or converting the temporary surcharge into permanent tariff rates through a tariff act. This would require both chambers to pass legislation and the President to sign it. Given current Congressional dynamics, a clean extension is uncertain. A more targeted bill addressing specific industries (steel, semiconductors) is more politically viable. New executive authority: the administration could invoke Section 201 of the Trade Act of 1974 (global safeguard actions) for specific industries, Section 232 for additional products, or other statutory authority that does not have a 150-day cap. Section 201 requires a formal ITC injury investigation and has its own procedural requirements, so it cannot be invoked on an overnight basis. Bilateral deal structure post-S122: the bilateral deal rates (EU 15%, Vietnam 18%, etc.) may survive as voluntary commitments by the foreign parties even without the Section 122 legal foundation. Some legal analysts argue the deals have become self-sustaining as part of an ongoing trade framework, regardless of the IEEPA ruling that initially enabled them. If bilateral rates persist, the post-S122 environment may not be as simple as "15% rate disappears." For planning purposes, model three scenarios: (1) S122 expires fully on July 24 with no replacement; (2) bilateral deals persist at their current rates but standard-S122-country goods drop to MFN; (3) new legislation or executive action maintains roughly current rates. Scenario 1 is the statute-based baseline. Scenarios 2-3 require political action.

The Section 122 expiration is not just a tariff planning question — it is a cash flow and inventory management question. Companies that import significant volumes need to model the working capital impact of the rate change. Customs duties are paid at the time of entry, not at time of sale. A company importing $2 million per month at a 20% effective tariff rate has $400,000/month in duty outflows, typically paid within 10 days of entry. Post-S122, if the rate drops to 5%, duty outflows fall to $100,000/month — freeing $300,000/month in working capital. The cash flow benefit has a lag: it begins with shipments that arrive after July 24. Shipments already in transit on July 24 will arrive and be entered at post-S122 rates. Shipments that had not yet departed when S122 expires will be entered at post-S122 rates. For companies that have been building inventory ahead of peak season (August-September back to school, Q4 holiday), the timing alignment may actually be favorable. Inventory imported in July-August to support Q4 demand will arrive at lower tariff rates if ordered with appropriate lead times after the expiration. The flip side: if you front-loaded inventory to avoid anticipated rate increases (a common strategy in 2025), you may be sitting on goods entered at high effective rates while competitors import at lower post-S122 rates in Q3-Q4. This creates a temporary competitive disadvantage until your high-duty inventory is sold through.
