Honourable Chief Minister and Honourable Minister,
Tamil Nadu's recent investment conclave — securing commitments of approximately ₹1.02 lakh crore — demonstrates the state's growing standing as India's preferred industrial partner. This submission respectfully places before you a corridor-level framework, Project KADARAM, that channels this momentum into the Virudhunagar–Tirunelveli–Thoothukudi belt by aligning existing state assets with Central schemes that are already open for application today.
This note is deliberately built to a different standard than a typical concept paper: every scheme, subsidy percentage, and physical fact cited below is drawn from a currently notified Central or State government source, current as of October 2026. Where a scheme was recently revised — as with the semiconductor packaging subsidy — this note states the current rate explicitly, so it does not mislead your technical staff.
"Tamil Nadu does not need to invent new central schemes. It needs to be the fastest, cleanest, most prepared state to receive the ones Delhi has already opened."
Project KADARAM resolves a common failure of large industrial proposals — departmental ambiguity — by drawing a clean line between what the Union Government funds and builds, and what Tamil Nadu independently controls.
For semiconductor packaging, the Kulasekarapattinam spaceport, and thorium siting — the Centre owns and funds the core asset. Tamil Nadu's role is to be the fastest, most litigation-free host: land, water, power, and permissions, cleared before the Centre asks.
For the Virudhunagar micro-clusters and intra-state logistics, Tamil Nadu is fully in charge — no Union approval required. Guidance Tamil Nadu, SIPCOT, and TIDCO organise, upgrade, and connect these units directly.
Every sector in this note is explicitly marked Track A or Track B, so your office knows in advance which file needs a Delhi signature and which does not.
| Sector | Governing Scheme | Central Support | Verified Facts |
|---|---|---|---|
| Semiconductor OSAT/ATMP Gangaikondan (Track A) | Semicon 2.0 / ISM, notified 31 Aug 2026 | 35% capex — advanced packaging 25% capex — legacy packaging | Min. capex ₹1,000 Cr & min. revenue ₹200 Cr required for eligibility |
| Space — Kulasekarapattinam Launch Complex (Track A) | Indian Space Policy 2023 / IN-SPACe | Fully Centre-funded (ISRO/DoS capex) | 2,233 acres; ₹950–986 Cr sanctioned; commissioning targeted FY2026-27 |
| Space — TIDCO Industrial & Propellant Park (Track A/B) | TN Space Industrial Policy | State-funded; IN-SPACe co-funds Allikulam facility (≤₹100 Cr) | 2,000-acre park near Kulasekarapattinam; Allikulam Common Technical Facility agreed 2026 |
| Thorium / Monazite Radhapuram belt (Track A) | Atomic Energy Act, 1962 (IREL/DAE) | Union monopoly — no state licensing possible | TN's role is limited strictly to land/water siting facilitation |
| Coastal Logistics Minor berths → VOC Port (Track A/B) | Sagarmala Coastal Berth Scheme | Up to 50% of project cost | Assistance extended to Major Ports/State Govt as applicant, not private SPVs directly |
| Grassroots CFCs Virudhunagar clusters (Track B) | Ministry of MSME — MSE-CDP Guidelines | 70% for ₹5–10 Cr projects; 60% for ₹10–30 Cr | 80–90% rate reserved for NE/hill states or >50% women/SC-ST/micro-owned clusters |
Tamil Nadu already leads Indian states in electronics exports and has enacted the Tamil Nadu Semiconductor and Advanced Electronics Policy (2024). Under Semicon 2.0 — notified by MeitY on 31 August 2026 — advanced packaging draws 35% central capex support, legacy packaging 25%.
KADARAM Action: Position SIPCOT Gangaikondan to attract an OSAT consortium meeting the ₹1,000 Cr minimum threshold, stacking state power-tariff and capital incentives on top of the Union subsidy.
Kulasekarapattinam's geography gives it a genuine, permanent advantage: rockets can launch directly south over open ocean without the fuel-costly manoeuvre required at Sriharikota to avoid overflying Sri Lanka. ISRO's spaceport there is nearly complete; TIDCO's adjoining 2,000-acre Space Industrial and Propellant Park, and the IN-SPACe-funded Allikulam facility, extend this into a private manufacturing ecosystem.
KADARAM Action: A dedicated, vibration-dampened freight corridor linking Gangaikondan's chip output to Allikulam's assembly lines and the Kulasekarapattinam launch complex — keeping the entire high-value chain inside the state.
Monazite sands along the Thoothukudi–Tirunelveli–Kanyakumari coast carry Thorium-232, central to India's long-term nuclear ambitions. Extraction and processing are a strict Union monopoly under the Atomic Energy Act, 1962, administered by IREL. Tamil Nadu has no legal path to license or process this mineral.
KADARAM Action: Pre-cleared, litigation-free land and water access in Radhapuram — a zero-capex administrative facilitation that positions Tamil Nadu ahead of competing coastal states when DAE next expands processing capacity.
Bulk, low-value cargo — farm goods, textiles, minerals — moves by short road transfer to minor coastal berths and onward by barge to V.O. Chidambaranar Port under the Sagarmala Coastal Berth Scheme. High-value, delicate cargo — microchips, avionics — moves instead by a dedicated highway lane on vibration-dampened transport, since sea transit risks humidity and shock damage.
KADARAM Action: TIDCO or the Tamil Nadu Maritime Board applies as the state agency of record for Sagarmala berth assistance, since the scheme funds ports/state governments rather than private operators directly.
Existing unorganised clusters — herbal foraging at Watrap/Shenbagathope, surgical cotton weaving at Rajapalayam, technical printing at Sivakasi, agro-processing at Sattur and Aruppukottai — currently operate in isolation. MSE-CDP already funds 70% of shared Common Facility Centres up to ₹10 Cr project cost.
KADARAM Action: Form cluster-level SPVs to sponsor CFCs at Chattarpatti, Sivakasi, and Aruppukottai, sequencing raw material through processing, packaging, and export compliance within the district itself.
The corridor spans three revenue districts in a continuous inland-to-coastal belt. Materials and value move from Virudhunagar's agro-textile clusters, through Tirunelveli's semiconductor siting, to Thoothukudi's space and port infrastructure — the two production streams described below both terminate at the coast.
High-value cargo — microchips from Gangaikondan, avionics from Allikulam — bypasses the port entirely, moving instead by dedicated highway lane directly to the Kulasekarapattinam launch complex, avoiding marine humidity and vibration risk that sea transit would pose.
Sivakasi — the seat of the Honourable Minister for Industries — appears twice on this map, once for chip-packaging lamination and once for export-compliance packaging, giving this corridor a direct constituency-level stake in its own success.
Scheme names, notified subsidy percentages, and physical facts (acreage, sanctioned costs, eligibility thresholds) — each sourced to a government notification, PIB release, or public scheme guideline current as of October 2026.
Line-item Detailed Project Report figures, an aggregate "pilot outlay" total, and derived growth-rate projections. No such DPR exists yet for any facility named in this note, and this concept stage is not the appropriate point to estimate them.
This is an intentional constraint, not an omission. The request below identifies the next step through which that data would responsibly be developed.
We request that this submission be logged with a reference number, so that it may be tracked and followed up in the normal course of departmental review.
We request that this note be referred to the appropriate desk within Guidance Tamil Nadu, SIPCOT, or TIDCO for a technical assessment of the corridor logic set out above.
Should your office find this corridor logic worth developing further, the Viksit Bharat Policy Cell would welcome the opportunity to assist Guidance Tamil Nadu or TIDCO — in whatever capacity your department finds useful, including a short-term research attachment — in developing the empirical, DPR-grade data this framework currently and deliberately omits.
Tamil Nadu is not being asked to create new central schemes, new legal authority, or new funding instruments. It is being asked to recognise that Delhi has already opened the door on semiconductors, space manufacturing, and maritime logistics — and to walk through it fastest, with the cleanest land and the clearest data, in the Virudhunagar–Tirunelveli–Thoothukudi corridor.
We submit this concept note with sincere respect for your time and your office's ongoing efforts to bring investment to Tamil Nadu, and with particular appreciation for the Honourable Minister's own engagement with the global semiconductor ecosystem. We remain available to provide any further detail, clarification, or supporting material this note may require.
Thank you for your consideration.
