Section 232 Chips and a Rs 2.6 Trillion Export Book: Where the Derivative List Bites Indian Electronics

Proclamation 11002 of 15 January 2026 imposed a 25 per cent ad valorem Section 232 duty on certain advanced semiconductors, semiconductor manufacturing equipment and derivative products, effective 12:01am EST on 15 January 2026 (White & Case, 2026; EY Global Tax News, 9 February 2026). Section 232 of the Trade Expansion Act of 1962 is a national-security instrument, so the duty sits outside the reciprocal-tariff arithmetic that Indian exporters spent most of 2025 modelling, and it is not negotiated away in the same conversations.

Three features of the measure matter more than the headline rate. First, it covers capital equipment, not only chips, so it reaches into the import side of India's fab build-out as well as the export side of its assembly base. Second, it reaches derivative products, meaning finished goods that contain a covered semiconductor rather than the chip alone. Third, it carries use-based carve-outs, which means two identical shipments can attract different duty depending on what the US importer does with them.

For an Indian exporter the practical consequence is that customs classification alone no longer tells you your exposure. The duty position depends on the derivative list, the end use declared by your buyer, and the timing of the entry.

CBP guidance CSMS #67400472 confirms that the tariff does not apply to chips used in the US for data centres, repairs or replacements, R&D, startups, or non-data-centre consumer and civil industrial applications. That is a wide set of exemptions, and it is why the headline rate overstates the exposure on a large part of India's finished-goods electronics trade.

A use-based exemption is a different animal from an origin-based one. An origin carve-out is fixed at the point of manufacture and can be documented once. A use-based carve-out depends on what the importer declares at entry, and on the importer's ability to sustain that declaration if CBP later asks for proof. The Indian exporter has no visibility into either.

That asymmetry has three commercial effects worth pricing:

• Your duty exposure is only as stable as your buyer's end-use declaration, and you will usually learn of a reclassification after the entry, not before.
• A buyer that gets an entry reclassified faces a retroactive duty bill and will look for someone to share it, which in practice means a price renegotiation on your open receivables.
• Where a US buyer serves multiple end markets, the same part number can flow into an exempt channel one quarter and a dutiable one the next, so historical duty experience is a weak predictor.

The practical response is a question, asked in writing, to every US customer: which exemption category are your entries cleared under, and do any of our part numbers reach an end use that sits outside all of them? File the answer in the credit file next to the financials. It is the single most useful piece of underwriting information available on this exposure, and no insurer will collect it for you.

India's smartphone exports were around Rs 2.6 trillion, about $29.4 billion, in FY26, with iPhones alone accounting for over 75 per cent at roughly Rs 2 trillion (Business Standard, 30 April 2026). That is the number that turns a chip tariff into a balance-sheet question.

Two things follow from the shape of that book. The first is scale: an export line of this size no longer behaves like a trade exposure that a firm can absorb from working capital. The second is concentration. A book where one product family accounts for more than three quarters of the value is a book where a single tariff decision, a single buyer decision, or a single change to the derivative list moves the whole line at once.

Trade credit underwriting handles concentration badly when the correlation is policy-driven. A credit insurer setting limits on a portfolio of US buyers assumes those buyers fail independently. A tariff change does not respect that assumption: it hits every buyer in the affected channel in the same week, for the same reason. The same logic that made US export concentration a credit-correlation problem applies here with sharper edges, because electronics assembly runs on thin margins where a 25 per cent duty cannot be absorbed anywhere in the chain.

For a broker placing this risk, the questions to put to the underwriter are concrete. What is the aggregate limit across all buyers exposed to the same derivative list? Does the policy carry a discretionary limit that would let the exposure grow without notification? And what happens to limits if the list expands mid-policy?

The chip itself is rarely what an Indian electronics exporter ships. What leaves Chennai, Sriperumbudur and Noida is a finished device with covered semiconductors inside it. That places the exposure squarely on the derivative-product mechanism rather than on the semiconductor line items.

Derivative lists under Section 232 have historically been expanded after the original proclamation, and each expansion works the same way: goods that were outside the measure on Monday are inside it on Tuesday, usually with very short notice and usually applying to entries made on or after the effective date. Goods already in transit do not get a grace period as a matter of course.

That creates a specific and underinsured moment. A container of finished devices that left an Indian port before an expansion, and lands after it, arrives as a shipment whose landed cost is 25 per cent higher than the one the buyer contracted for. The buyer's options at that point are to pay, to renegotiate, or to refuse the delivery. Only one of those three is good for the exporter.

What to model, and at what tenor

Run the exposure at three horizons rather than one:

1. In-transit stock right now. Value of goods on the water plus goods in bonded or overseas warehouses, against the possibility of a list expansion landing during that window.
2. The open order book. Orders accepted but not yet shipped, where the contract price was set on a pre-expansion duty assumption.
3. Receivables past 90 days. Amounts owed by buyers whose own duty position could change before they pay you.

The first two are stock and marine questions. The third is a trade credit question. Firms routinely model only the third and discover the first two during a claim.

India launched Semicon 2.0 on 15 July 2026 with an allocation of Rs 1.275 trillion, about $13.23 billion, spanning fabrication, advanced packaging, equipment and speciality materials (India Briefing, 2026). The scheme funds a large inbound flow of semiconductor manufacturing equipment at exactly the moment US policy has put a 25 per cent duty on that equipment category moving the other way.

The Tata Electronics and PSMC Dholera fab targets first silicon in December 2026, at 50,000 wafer starts per month across 28nm to 110nm nodes (Data Center Dynamics and Invest India, 2026). Equipment for a project on that timetable is high-value, long-lead, frequently single-source, and arriving against a fixed commissioning date.

The insurance work on the inbound leg is different from the export leg and is often handled by a different team inside the same company:

• Marine cargo on high-value tools, written on an open cover with sums insured that reflect replacement cost and current freight, not the historical invoice value.
• Delay in start-up cover, attached to the marine placement, so that a damaged or delayed tool converts into an indemnity for the fixed costs and lost margin of a postponed commissioning rather than a pure repair claim.
• Erection all risks across installation and hook-up, with the handover to operational cover mapped in advance. The construction-to-operations handover on a fab is where the most expensive coverage gaps sit.

The exposure splits cleanly into three placements. Confusing them is the most common error in this class.

Trade credit on the buyer concentration

Trade credit responds to buyer insolvency and to protracted default on an undisputed debt. It is the right instrument for the risk that a US buyer, squeezed by a duty it did not plan for, simply fails or stops paying. It is a weak instrument for the risk that a buyer withholds payment while demanding a price adjustment, because that is a dispute, and most wordings suspend a disputed receivable until the dispute is resolved in the exporter's favour.

The practical steps are unglamorous and they work. Notify the insurer as soon as a buyer raises a duty-driven price demand rather than negotiating in silence. Convert any concession into a written bilateral amendment so the residual balance stays undisputed. Obtain insurer consent before extending terms or writing anything off, because the policy almost certainly requires it. The same discipline that applies to ECGC and commercial trade credit placements generally applies here, with the added step of documenting the buyer's exemption category.

Stock throughput on goods already in the channel

A marine cargo policy covers transit. It stops when the goods reach the named destination and, in many wordings, within a stated number of days after discharge. Finished electronics waiting in a US warehouse for a duty question to be resolved are past that point. Stock throughput cover, which follows the goods from supplier through transit into overseas storage and out again on a single policy wording, is the placement that closes the gap. Check three things: whether the overseas warehouse locations are declared, whether the sum insured reflects landed value including duty, and whether the storage extension has a time limit that a prolonged tariff dispute would exceed.

The third placement, marine cargo and delay in start-up on the inbound equipment, is set out in the section above. The point to hold on to is that it is a separate placement with separate triggers, and the fact that both legs stem from the same tariff measure does not make them one risk.

Insurance sits downstream of the contract. Before testing whether a policy responds, establish who owes the duty under the sale terms, because that determines whether you have a receivable problem or a cost problem.

Incoterms do most of the work. On DDP terms the Indian seller is the party responsible for import clearance and duties, so a list expansion lands directly on the seller's margin with no receivable dispute at all. On DAP, FOB or CIF terms the US importer clears the goods and pays the duty, which moves the exposure into the credit and dispute column. Firms that shifted to DDP to make buying easier during the 2025 order push should recheck what that decision now costs.

The clauses that decide the rest:

• Change-in-law and price-adjustment clauses. These are the clean route to sharing an unexpected duty. Absent one, the party holding the obligation holds the whole cost.
• Force majeure. A tariff usually does not qualify. Force majeure excuses performance that has become impossible, and a duty makes performance expensive rather than impossible. Do not plan around it.
• Delivery and acceptance terms. A buyer refusing to take delivery of goods that have become uneconomic is a non-acceptance event, which sits in a different part of a trade credit wording from insolvency and is frequently subject to a lower limit or a separate deductible.

Where Indian exporters were caught in the earlier round of US measures, the pattern was the same: the tariff analysis was done in the finance team, the contract analysis was done in legal, and the insurance analysis was done by the broker, with nobody holding all three. The earlier work on trade credit and marine cover under the 2026 US tariffs makes the same point from the transit side.

Ordered by how quickly it pays back.

1. Map the derivative exposure by part number. For every SKU shipped to the US, record whether it contains a covered semiconductor and which end market the US buyer serves. This is the base document for everything else.
2. Get the exemption category in writing from each buyer. Data centre, repair and replacement, R&D, startup, or non-data-centre consumer and civil industrial. A buyer that cannot answer is a buyer whose duty position can change without warning.
3. Aggregate credit limits by tariff channel, not by buyer. Ask the underwriter what the combined limit is across all buyers exposed to the same derivative list, and whether a mid-policy expansion triggers a limit review.
4. Value the in-transit and warehoused book weekly. Goods on the water and goods in overseas storage are the population exposed to a list expansion that carries no notice period. Know the number before you need it.
5. Recheck the Incoterm on every US contract. DDP puts import clearance and duty on the Indian seller, which converts a buyer problem into a direct margin problem with no receivable to claim on.
6. Put the uninsured residual in the board pack as a rupee figure. When one product family carries more than three quarters of a Rs 2.6 trillion line, the credit limit on the largest buyer is a statement about how much revenue is unprotected, not a technical parameter.
7. Size the delay in start-up indemnity period against real lead times. On equipment funded under Semicon 2.0 and destined for a fab targeting first silicon in December 2026, an indemnity period of six months against a twelve-month single-source replacement will pay roughly half the loss.

Recalculate items 1, 3 and 4 whenever the derivative list moves rather than waiting for renewal. The list is the variable that reprices the whole book at once, and it moves on Washington's timetable rather than yours.
