Context and Objectives
A leading automotive OEM was required to supply on-board CNG cylinders for a CNG vehicle. It wanted to determine the most cost-effective approach for sourcing on-board CNG cylinders. The key question was whether it would be more viable to set up a manufacturing facility in India or import finished cylinders from China.
The decision needed to align with a pre-defined target selling price, making cost efficiency and unit economics central to the analysis.
Study Objectives:
1. Assess the financial viability of manufacturing CNG cylinders in India.
2. Conduct a Make vs. Buy (Import) analysis across different production volumes.
3. Perform a sensitivity analysis to understand scale effects, breakeven points, and long-term profitability.
Financial Analysis - Make vs. Buy Analysis for CNG Cylinder Manufacturing in India
Approach and Methodology
1. Make-or-Buy Decision Framework
Instrex applied a structured, data-driven Make vs. Buy framework that integrated financial modeling with techno-commercial feasibility.
The analysis compared two core scenarios:
Scenario A: Setting up a greenfield manufacturing plant in India
Scenario B: Importing finished CNG cylinders from China
Both were evaluated at the same target realized selling price to ensure a fair, like-for-like comparison.
2. Techno-Commercial Feasibility Assessment
For the manufacturing scenario, a comprehensive feasibility study was conducted, factoring in:
Machinery and layout requirements
Power and utility consumption
Production yield, wastage, and quality losses
Labour and manpower deployment
Regulatory and certification requirements (PESO, BIS)
This approach ensured realistic production cost estimates rather than relying on theoretical benchmarks.
3. Capital Expenditure (CAPEX) Estimation
A detailed financial model was developed to calculate the one-time investment needed to start operations.
For Indian Manufacturing:
Land acquisition
Plant and building construction
Machinery procurement
Office setup and equipment
Pre-launch manpower and overheads
Working capital (equivalent to 3 months of operating costs)
For Imports from China:
Licensing and regulatory approvals
Minimal fixed infrastructure investment
4. Operational Expenditure (OPEX) Build-Up
A bottom-up model was created to estimate recurring monthly costs.
Variable Costs:
Raw materials
Consumables
Utilities and power
Fixed Costs:
Staff and labour
Administrative and plant overheads
Compliance and regulatory expenses
For imports, all logistics-related expenses—freight, customs duty, port charges, and handling—were fully accounted for.
5. Unit Economics and Cost of Production
To determine the true cost per cylinder, both cash and non-cash expenses were included.
- Cash Costs: Raw materials + OPEX
- Non-Cash Costs: Depreciation
- Financial Costs: Interest on total capital employed (CAPEX + 3 months working capital)
This ensured the analysis reflected the complete financial impact of each business model.
6. Revenue, Profitability, and Sensitivity Analysis
Revenues were calculated using the customer’s target selling price.
The profitability assessment included:
- Monthly and annual profit projections
- Breakeven and payback period analysis
A scenario-based sensitivity analysis was run across multiple production volumes to evaluate:
- Economies of scale
- Movement in unit costs
Minimum viable production volume for profitability.
Conclusion and Recommendations
Key Insights
The study concluded that manufacturing CNG cylinders in India from day one would not be financially viable, primarily due to:
A steep operational learning curve — achieving regulatory compliance and manufacturing precision could take up to a year
High capital investment and fixed overheads
Unfavorable unit economics at lower volumes
Low or negative profitability in the initial years, even at target prices
Recommended Two-Stage Strategy
Stage 1: Import and Stabilize
Import finished CNG cylinders from certified Chinese suppliers
Obtain PESO certification for 1–2 partners
Begin supplying the OEM with minimal upfront investment
Build operational experience and market credibility
Stage 2: Transition to Local Manufacturing
Once demand stabilizes and internal capabilities strengthen
After establishing strong regulatory relationships (PESO, BIS)
Gradually shift to local manufacturing to reduce dependence on imports and improve margins over time
Outcome
This staged approach provided the OEM with a practical, low-risk entry strategy—balancing short-term feasibility with long-term competitiveness.
