Industrial real estate: the logistics tailwind isn't over

Since July 2025 a 40% US penalty has applied to goods merely routed through Vietnam, against 20% on genuinely Vietnamese output. That rule, not the cap rate, now decides which industrial leases survive a customs audit.¹

The structural case for South East Asia logistics still holds. China+1 relocation, e-commerce, and supply-chain diversification keep underwriting demand for modern warehousing, and a cyclical soft patch in ready-built rents does not break the long-run thesis. Vietnam drew US$27.6 billion of realised foreign direct investment (FDI) in 2025, up about 9% on the prior year and the highest in five years, with manufacturing and processing about 59% of the total.² Demand held through the tariff shock. What changed is the test of durability.

The field has read the policy and underweighted the property implication. The 2025–26 US–Vietnam trade settlement was heavily covered; what the market has been slow to price is what it does to an industrial lease. Durability used to turn on location and building spec. It now turns on which side of the 20%/40% line each tenant's goods fall on. That converts a rent roll into a set of trade-origin covenants, underwritten tenant by tenant, before any of it shows up in vacancy data.

Why the cap rate stopped being the test

Underwrite the tenant's origin substance, not the building. You can read a cap rate, a location, and a spec off a floor plan. You cannot read whether a tenant's goods would survive a US customs origin audit, and that is now the line that separates a strong covenant from a weak one.

The house read on what holds value is unchanged in shape. Durability is location, plus a strong tenant covenant, plus re-leasing optionality, not the trophy bought at a peak-cycle yield for its address. The trade settlement upgraded the covenant term. A tenant's credit no longer rests only on its balance sheet; it rests on whether its goods qualify as Vietnamese-origin under the new rules. Two warehouses with the same nameplate, location, and headline yield can now be worth markedly different amounts, separated by the origin substance of the goods inside them. That distance is where the underwriting work moves.

What the 20%/40% line does to a rent roll

Sort every tenant onto one side of the line. The test reduces to a single screen run across the rent roll, and durability tracks the weighted mix it produces, not the building's distance to a port.

On one side sit genuine-transformation occupiers: tenants whose goods undergo enough work in Vietnam to qualify for the 20% reciprocal rate. To clear that bar, goods must show substantial transformation, an indicative regional-value-content (RVC) test of roughly 35–40% of value added in-country. That figure is indicative and pending the final signed text, not settled law, and sits well clear of the settled 75% threshold that governs autos under the separate USMCA regime.³ These are the sticky covenants. They are the manufacturing engine that took about 59% of 2025 FDI, and they pay for compliant, well-located, well-powered space.

On the other side sit assembly-and-relabel operators dependent on Chinese inputs, exposed to the 40% transshipment penalty, applied with no published remission.¹ These are the weak covenants. The risk is not theoretical. A Harvard, Duke, and Academia Sinica study reported more than US$8 billion of Chinese exports rerouted through Vietnam to the US in the first three quarters of 2025, reversing a two-year decline.⁴ Rerouted goods need ready-built logistics space when they move through formal channels, so part of that flow is exposure an investor underwriting southern warehouse stock should test for, not assume away.

You can read a cap rate, a location, and a spec off a floor plan. You cannot read whether a tenant's goods would survive a US customs origin audit, and that is now the line that separates a strong covenant from a weak one.

Is anyone actually enforcing it?

Enforcement is real today, not nominal, which is the condition the whole read depends on. This is the single test of whether the covenant split has any cash-flow consequence, so it earns the closest look.

US Customs and Border Protection (CBP) uncovered more than US$400 million in unpaid duties through its trade-evasion programme between 20 January and 8 August 2025, across 89 cases with reasonable suspicion of evasion; the largest case on record involved 23 US importers and a network of Chinese shell companies routing goods through Indonesia, South Korea, and Vietnam, with more than US$250 million owed.⁵ The enforcement apparatus is being built out through 2026, with a multi-agency trade-fraud task force, AI-based risk-scoring, and customs guidance on illegal transshipment.⁶ An importer that can document Vietnamese origin pays 20%; one that cannot faces the 40% penalty. That gap is what turns origin substance into a priced credit variable rather than a paperwork footnote.

One caveat travels with this. The penalty is live but on a temporary legal footing. After the US Supreme Court struck down the original tariff authority on 20 February 2026, the 40% penalty was reissued under Section 122 of the Trade Act of 1974, unchanged in rate and scope, with CBP still unable to remit it. Section 122 runs 150 days from 24 February 2026 and expires on 24 July 2026 unless extended, with a longer-lived replacement expected.⁷ The mechanism, not the direction of travel, is what carries an expiry date.

Base, better, worse: how the covenant split could resolve

The worse case has a second leg worth naming separately: a cyclical demand air-pocket could deepen as ready-built warehouse supply runs ahead of take-up, or the grid constraint could bite before generation arrives and strand otherwise-good sites. Structural demand stays anchored by FDI at a five-year high.⁸

Two warehouses with the same nameplate, location, and headline yield can now be worth markedly different amounts, separated by the origin substance of the goods inside them.

What to watch, and what to ask before buying

This read is a covenant-quality discipline layered on an intact structural thesis, sized to the dispersion it can evidence. A handful of signposts tell you which case is unfolding:

• Published CBP transshipment determinations through 2026 — their count, size, and whether remission is granted in practice.
• The final signed US–Vietnam agreement text and the confirmed RVC threshold; the 35–40% figure is indicative pending that text.³
• Vietnam's realised-FDI run-rate and manufacturing share into 2026, the demand engine that anchored at US$27.6 billion and about 59% for 2025.²
• Industrial land occupancy and rent trends, and the ready-built warehouse occupancy gap, refreshed each quarter against current CBRE, Savills, or Cushman & Wakefield data; anything older than a quarter reprices.⁸
• PDP8 generation and transmission build against schedule, and grid availability at industrial-park level.⁹

The diligence questions follow the same spine. For each material tenant, can the occupier evidence substantial transformation in Vietnam at or above the RVC threshold, and would its goods survive a CBP origin audit? What share of rent comes from tenants dependent on Chinese intermediate inputs, and what is the lease tenor on those weak covenants? If a weak-covenant tenant exits after an audit failure, can the box be re-let to a compliant occupier at a sensible rent? Is the asset's power and grid connection secured for a higher-spec tenant, or does it sit behind a PDP8 transmission queue? And does the location still command its rent on fundamentals, so the asset holds if the compliance edge fades? These are market-level questions any buyer should run, not positions or recommendations.

The case against this read

The strongest counter is that the transshipment penalty is political theatre customs cannot enforce at scale. CSIS makes the structural version: rules-of-origin enforcement is hard in countries with close ties to China and little incentive to help US enforcement, and transshipment behaves like squeezing a balloon, with the deficit reappearing elsewhere rather than disappearing.¹⁰ Add that the 35–40% RVC threshold is indicative, that the final text could set a bar assembly operators clear cheaply, and that the Section 122 legal basis expires on 24 July 2026, and the edge looks fragile.

Two of those points answer to evidence the piece already holds; two it cannot answer, and sizing handles them. On whether customs can enforce, the CBP record is the direct reply: a programme that surfaced more than US$400 million in unpaid duties in seven months, with a single network owing more than US$250 million, is enforcement with teeth, not theatre.⁵ On whether documenting origin pays, Federal Reserve work on USMCA autos shows rules-of-origin compliance is itself a cost the Fed pegs at roughly 1.4–2.5% tariff-equivalent, and firms skip it when the duty saved falls below that.¹¹ A Vietnamese tenant captures the full gap between the two rates, 20 points of tariff, by qualifying. A 20-point stake against a compliance cost near 2% clears the threshold by close to an order of magnitude, so here origin compliance does pay, and so does sort tenant credit.

What sizing handles, not evidence, is the rest. The final text could narrow the penalty, and Section 122 could lapse. Neither is in hand today, so the position is held as a covenant-quality discipline on an intact structural thesis rather than a standalone bet, sized to the dispersion between compliant and weak covenants it can evidence. Nominal enforcement, or a lapsed or narrowed penalty, is the line that empties the edge.

Why the operator vantage sees this first

Orofante reads an industrial asset from inside the tenant's operations, not off a yield sheet, because the firm invests its own balance sheet across both Vietnamese real estate and the materials and manufacturing supply chain. A rent roll gets tested for origin substance the same way a counterparty's supply chain does. That dual seat is why the transshipment-compliance split is visible before it surfaces in occupancy statistics.

The motif runs across the cluster. The same 2026 policy shift that reprices a recycled tonne by its provenance reprices a warehouse by the origin substance of its tenant's goods; we develop the materials side in the rPET spread outlook. The power and grid-connection constraint that is the next-order screen on the best sites is the subject of the AI-infrastructure supply-chain note, and the financing of South East Asia infrastructure, where financial close is the real test, in the waste-to-energy financing note. The broader rented-versus-durable lens, where headline strength is funded by something thinner, here tenant credit resting on rules-of-origin substance, runs through the consumer-resilience note.

The structural case for South East Asia logistics is intact. What changed is the test of durability: not the address, but whether the goods inside the box can prove they were made here. Until the enforcement record and the signed text resolve, that is a covenant-quality screen run tenant by tenant, sized to the dispersion it can prove.
