Short answer: Low-cost auto parts is a game of localisation rates and industrial clusters. A brake disc, gasket or wiring harness only makes money when steel, plastics and rubber suppliers sit within a few hours’ delivery radius and moulds get repaired the same day. India has complete auto clusters (Chennai, Pune) with deep tier-2/3 supply chains; Vietnam offers labor-cost advantages, a position inside the ASEAN supply chain and FTAs (CPTPP, EVFTA, RCEP) for exports. This article works through Vietnam’s legal framework (as of 18 October 2026) against India’s at a high level.
1. Why “Low-Cost” Does Not Mean “Put It Anywhere”
Low-cost auto parts (brakes, filters, gaskets, wiring, interior plastics…) run on thin margins — 3–5% is typical. At such margins, three factors are existential:
- Real localisation rate: every imported container of inputs is one more exposure to exchange rates, lead times and logistics cost. A plant reaching 70–80% local content has a fundamentally different cost structure from one importing 70% of inputs.
- Tooling: auto parts live on moulds. A broken mould sent far away for a two-week repair stops the line for two weeks. A cluster with mould shops and heat-treatment workshops within 50 km is an advantage no wage table shows.
- OEM approval: parts entering Toyota, Hyundai or Tata supply chains must pass supplier approval (testing, plant audits). Approval earned in one country travels best when production stays there — moving the plant often means redoing part of the process.
2. Vietnam’s Legal Framework for an Auto-Parts Plant
- Investment: The Law on Investment No. 143/2025/QH15 (effective 1 March 2026) + Decree No. 96/2026/ND-CP — IRC issuance. Auto parts fall under supporting industries and may qualify for sector-based investment incentives. Note: Vietnam has dedicated incentives for supporting industries — check the current incentive schedule when designing the project (not every part type automatically qualifies).
- Land: The Land Law No. 31/2024/QH15 (effective 1 August 2024) — land lease inside industrial parks; Decree No. 35/2022/ND-CP. Parts plants need to be near ports (for export) or near vehicle assembly plants (for domestic supply) — park location decides daily logistics cost.
- Environment: The Law on Environmental Protection No. 72/2020/QH14 — environmental impact assessment / environmental licence. Plating, painting and pressure die-casting generate wastewater, emissions and hazardous waste — requirements vary by process.
- Labor: the 2019 Labor Code; auto parts need skilled workers (CNC operation, quality inspection) — training and retention costs belong in the equation. Foreign specialists need work permits under Decree No. 219/2025/ND-CP (effective 7 August 2025).
- Tax and customs: 20% CIT + supporting-industry incentives (if conditions are met); parts exported to ASEAN enjoy FTA preferences (ATIGA within ASEAN, RCEP, CPTPP) depending on destination and origin rules. Customs under the Customs Law No. 54/2014/QH13.
3. Four Comparison Pillars
Pillar 1 — OEM proximity and cluster depth: India: the Chennai (“Detroit of Asia”) and Pune clusters with full tier-2/3 suppliers, mould shops and OEM R&D centres. Vietnam: developing clusters (Hai Phong–Quang Ninh vehicle assembly, Chu Lai); tier-2/3 chains are growing but shallower. Count the suppliers for your 10 key inputs around each candidate park.
Pillar 2 — Tooling ecosystem: survey in practice: how many mould-making and mould-repair shops within 50 km? Emergency mould-repair lead time? This hidden cost decides the ability to serve rush orders.
Pillar 3 — Technical labor: CNC, casting and QC inspection need trained workers. Compare training costs, attrition and time-to-full-productivity for a new hire in each country.
Pillar 4 — Destination markets and FTAs: exporting to ASEAN — both have FTAs (Vietnam via ATIGA/RCEP; India via its own ASEAN FTAs). Exporting to the EU — Vietnam has the EVFTA. Look up rates for the exact HS code of the specific part.
| Factor | Vietnam (current framework) | India (high-level framework) |
|---|---|---|
| Auto cluster | Developing (Hai Phong, Chu Lai) | Complete (Chennai, Pune), deep tier-2/3 chains |
| Supporting-industry incentives | Sector/location incentives (check current schedule) | Domestic-manufacturing incentive framework |
| Export FTAs | ATIGA, RCEP, CPTPP, EVFTA | FTAs with ASEAN and partners |
| Investment procedure | IRC under Law on Investment 143/2025 + Decree 96/2026 | Own investment approval framework |
India’s framework is high-level only; details to be checked by local counsel.
4. Worked Scenario: Brake Discs for ASEAN
Suppose you make brake discs — 70% exported to Thailand and Indonesia (ASEAN markets), 30% sold to a domestic vehicle assembler:
- Step 1: List key inputs (steel/iron blanks, friction material). Count suppliers within a 4-hour delivery radius of each candidate park; compute the achievable localisation rate.
- Step 2: Look up FTA rates for the brake disc’s HS code exporting from Vietnam (ATIGA/RCEP) versus from India into Thailand/Indonesia — duty gaps eat directly into thin margins.
- Step 3: For Vietnam: IRC (check supporting-industry incentive eligibility), park land near the port or the OEM, EIA for casting/plating stages (if any), work permits for specialists.
- Step 4: Assess the tooling base: emergency mould-repair time and new-mould cost in each country — for low-cost parts, tooling cost allocated per piece is material.
5. First-30-Days Checklist
- Lock in 3 hero part lines + HS codes + destination (domestic OEM vs export).
- Count suppliers for 10 key inputs within 200 km of each candidate park.
- Survey tooling shops within 50 km: capability, emergency repair lead time.
- Look up FTA rates for the exact HS code; model post-tax, post-logistics margins.
- Engage local counsel in India to check supporting-industry incentive conditions before signing an MOU.

Frequently Asked Questions
1. What incentives do “supporting industries” get in Vietnam?
Auto parts fall under supporting industries and may receive investment incentives (time-limited CIT exemption/reduction; land-rental preferences) if sector and location conditions in the current schedule are met. Specific conditions (part type, localisation rate, technology) must be checked when designing the project — not every part automatically qualifies.
2. How does the localisation rate affect the location decision?
Enormously. At 3–5% margins, each percentage point of logistics cost and exchange-rate risk from imported inputs matters. A plant at 70–80% localisation is not just cheaper but more resilient to supply-chain shocks. Compute the localisation rate actually achievable in each country, not the target figure on paper.
3. Why does a nearby mould shop matter so much for low-cost parts?
Because a broken mould means a stopped line. With thin margins, tooling cost allocated per piece is material, and mould-repair waiting time is a direct opportunity cost. A cluster with mould shops within 50 km cuts downtime from weeks to days — an advantage no wage comparison shows.
4. What duty rates apply exporting auto parts from Vietnam to ASEAN?
Depending on the exact HS code and agreement (ATIGA within ASEAN, RCEP…). Many auto-part lines enjoy 0% or low preferential rates when origin rules are met. Look up the exact HS code and obtain the matching C/O on export.
5. How does the EV transition affect a low-cost parts plant?
EVs eliminate many internal-combustion parts (exhaust systems, some engine components) but create new demand (battery trays, electrical-system parts, battery cooling). A low-cost parts plant should assess: what share of its current catalogue works for EVs, and what retooling costs — before committing to a 10–15-year investment.
