Three forces converged this week to fundamentally alter the cost basis for capital project procurement. Restructured Section 232 tariffs took effect April 6, applying new rates across steel, aluminum, and copper derivatives. The Section 301 comment deadline — the last opportunity for procurement organizations to influence permanent tariff rates on manufactured goods — arrives April 15. And Brent crude remains above $120 per barrel as the Strait of Hormuz stays effectively closed despite a ceasefire agreement. For teams managing multi-vendor RFQs, the practical implication is that every quote submitted before April 6 now carries a different tariff basis, and every quote influenced by energy costs is shifting in real time.
Restructured Section 232 Tariffs Rewrite the Math on Metal-Intensive Procurement
On April 6, restructured Section 232 tariffs took effect with three changes that directly impact how procurement teams evaluate vendor pricing. First, primary steel, aluminum, and copper articles now face a 50% tariff — applied to the full customs value of the item, not just the metal content. Second, derivative goods containing more than 15% steel, aluminum, or copper by weight face a 25% tariff, also on full customs value. Third, a temporary 15% rate applies to metal-intensive industrial and electrical grid equipment through December 2027.
| Category | Tariff Rate | Applies To |
|---|---|---|
| Primary steel, aluminum, copper articles | 50% (full customs value) | Chapters 72, 73, 74, 76 products |
| Derivative goods (>15% metal content) | 25% (full customs value) | Manufactured goods with significant metal |
| Grid & industrial equipment | 15% (temporary through 2027) | Transformers, switchgear, electrical equipment |
| US-origin metal derivatives | 10% | Goods made entirely with US-smelted metal |
| Russian-origin aluminum | 200% | All Russian aluminum products |
The shift to full customs value is the critical detail. Previously, tariffs on derivative products applied only to the metal portion of the article’s value. A $100,000 switchgear assembly with $30,000 in steel content was taxed on the $30,000. Now it is taxed on the full $100,000. For EPC and T&D procurement teams evaluating bids on transformers, switchgear, structural steel assemblies, and piping systems, this changes the landed cost calculation for every imported component.
Key takeaway: Vendor quotes submitted before April 6 do not reflect the restructured tariff basis. Procurement teams processing active RFQs for metal-intensive equipment should flag every imported line item for tariff revalidation — and track whether vendors are absorbing, passing through, or restructuring their supply chains in response. The 15% temporary rate on grid equipment provides some relief for T&D teams, but the December 2027 expiration creates a procurement window: equipment ordered and delivered before that date locks in the lower rate.
Section 301 Comment Deadline Arrives — Last Window to Shape Permanent Tariff Rates
The April 15 deadline for written comments on the USTR’s two parallel Section 301 investigations is now two days away. As covered in our March 30 brief, these investigations target structural excess capacity across 16 economies and forced labor enforcement across 60 trading partners — covering steel, aluminum, chemicals, plastics, machinery, batteries, semiconductors, and construction materials.
What has changed since our last coverage: Crowell & Moring’s analysis of the seven most common questions from affected businesses makes clear that participation is not a formality. Companies that file tailored, company-specific comments position themselves to obtain product exclusions from any resulting tariffs and preserve the right to challenge outcomes at the U.S. Court of International Trade. Companies that do not participate face limited ability to seek exclusions later.
The timeline after April 15:
- April 15: Written comments and hearing requests due (both investigations)
- April 28–May 1: Public hearings on forced labor enforcement track
- May 5–8: Public hearings on industrial excess capacity track
- Post-hearing: Rebuttal comments due within seven calendar days
- Mid-to-late 2026: Tariff determinations possible, potentially aligning with July expiration of temporary Section 122 tariffs
Unlike the struck-down IEEPA tariffs, Section 301 tariffs have no statutory cap or expiration. The rates set through this process will be permanent absent a future reversal — making this the most consequential input window procurement organizations will have in 2026.
Key takeaway: For procurement leaders managing capital project supply chains that depend on imported materials from the 16 targeted economies, the next 48 hours represent the narrowest and most consequential window to influence tariff outcomes. The filing requirements are not onerous — company identification, an interest statement, and substantive commentary addressing the investigation — but the evidence must be concrete and company-specific. Organizations with quantifiable data on how tariffs affect capital project costs and domestic sourcing constraints should prioritize filing before the deadline closes.
Hormuz Remains Closed Despite Ceasefire as Brent Holds Above $120
The Iran ceasefire agreement announced in late March has not translated into reopened shipping lanes. As of April 9, Abu Dhabi National Oil Company CEO Sultan Al Jaber confirmed that the Strait of Hormuz remains effectively closed, with Iran restricting and conditioning traffic despite the ceasefire. An estimated 230 loaded oil tankers are waiting inside the Gulf. Dated Brent — the spot price for physical oil cargoes — settled at $124.68 per barrel on April 8, following an average of $103 per barrel in March that already represented a $32 increase from February.
The supply impact is structural, not transient. Middle East producers have shut down approximately 13 million barrels per day of production due to collapsed tanker traffic. Restoring that capacity could take up to five months even after the strait fully reopens. The cascading effects — on LNG contract pricing, petrochemical feedstocks, diesel-dependent logistics, and petroleum-derived construction materials — are compounding the cost pressures detailed in our March 30 and April 6 briefs.
For procurement teams, the dated Brent price is the leading indicator. It represents the price at which physical oil is actually trading for near-term delivery — not the futures price. When dated Brent sustains above $120, every petroleum-derived input category (plastics, coatings, resins, insulation, adhesives) and every energy-intensive manufacturing process (steel, aluminum, glass, cement) faces sustained cost escalation that will flow through vendor pricing over the coming weeks.
Key takeaway: Quote validity windows are compressing further. Vendors pricing energy-intensive materials or petroleum-derived products against March cost assumptions are already underwater. Procurement teams should build systematic revalidation into active RFQ cycles — not as a one-time exercise, but as a recurring process that tracks the delta between original submissions and resubmissions across every line item. The teams that can normalize resubmissions rapidly and surface exactly what changed will make faster, more defensible award decisions as pricing continues to shift.
KPMG Survey: Reshoring Accelerates but Margins Continue to Erode
The KPMG 2026 Tariff Survey, published this week, quantifies what procurement teams have been experiencing: tariff costs are now firmly embedded in the operating environment, and businesses are responding with a mix of price increases, reshoring acceleration, and specialized hiring — but margins continue to shrink.
| Metric | Current | Previous | Change |
|---|---|---|---|
| Companies passing >50% of tariff costs to consumers | 34% | 13% (May 2025) | +21 pts |
| Executives planning price increases (up to 15%) | 55% | — | — |
| Companies in formal reshoring planning/execution | 26% | 10% (6 months prior) | +16 pts |
| Companies reporting declining foreign sales | 82% | — | — |
| Companies reporting declining domestic sales | 61% | — | — |
| Sourcing cost increases | >25% | — | — |
| Companies hiring for specialized tariff roles | 33% | 22% (Sept 2025) | +11 pts |
Two findings stand out for procurement leaders. First, the reshoring acceleration — from 10% to 26% in formal planning or execution in six months — signals a structural shift in where companies source, not a temporary hedge. But 60% of those companies estimate reshoring will take one to three years, meaning the tariff cost burden hits immediately while the supply chain restructuring takes years to deliver relief.
Second, KPMG’s biannual supply chain report frames trade policy as a permanent standing cost rather than a disruption to wait out. With the USMCA renegotiation scheduled for summer 2026 — where removal of existing carve-outs could add six percentage points to the current ~12% tariff rate — and Section 301 investigations targeting 16 economies, the tariff landscape is still expanding, not stabilizing.
Key takeaway: For procurement teams evaluating vendors across multiple sourcing regions, the tariff cost structure has become a core evaluation variable alongside price, technical compliance, and delivery schedule. Vendors sourcing from different regions carry fundamentally different landed cost trajectories — and those trajectories are diverging as tariffs layer. Normalizing vendor submissions to make tariff exposure visible and comparable across dozens of bids is no longer a nice-to-have; it is a requirement for defensible award decisions in a landscape where the rules change quarterly.
What to Watch
- April 15: Section 301 written comments due. This is the final deadline for procurement organizations to submit company-specific evidence on how tariffs on manufactured goods affect capital project costs. Public hearings follow April 28 (forced labor) and May 5 (excess capacity). Organizations that miss this window have limited recourse to seek product exclusions later.
- Section 232 derivative goods expansion. The April 6 proclamation authorizes cabinet officials to add derivative products to Section 232 coverage on a rolling basis. Watch for additional product categories being swept into the 25% derivative rate — particularly downstream industrial equipment not currently listed.
- Hormuz reopening timeline. With 230 tankers still waiting and 13 million bpd shut in, the physical oil market remains in structural deficit. Even if Iran begins allowing traffic, restoring pre-crisis flow volumes will take months. Track dated Brent and LNG spot prices as leading indicators for when cost pressures will begin easing — or intensifying further.
