Local-Sourcing Rules Can Create a Shortage of Their Own

21 August 2026

Executive Summary

Governments around the world are encouraging businesses to reduce dependence upon foreign suppliers.

India’s solar industry demonstrates an important unintended consequence:

Moving faster than domestic manufacturing capacity can create a shortage during the transition.

Indian rules effective from 1 June 2026 require solar modules used in many qualifying projects to contain solar cells from manufacturers on the government’s Approved List of Models and Manufacturers — ALMM List II. Official Indian policy documents confirm the June implementation date.

The objective is to strengthen domestic manufacturing and reduce reliance upon imported Chinese components.

But Reuters reports that nearly one-third of India’s 140 small and medium solar-module manufacturers have halted production, while others have reduced operating cycles because sufficient approved domestic solar cells are not available. Some manufacturers are facing waits of six to eight months.

This is a highly transferable risk lesson:

A policy intended to make a supply chain more resilient can temporarily make it less resilient.

UK Impact

The principle is directly relevant to UK companies navigating:

• Local-content requirements.
• Procurement rules.
• Sanctions.
• ESG sourcing standards.
• Government subsidy conditions.
• Security-of-supply rules.
• Approved-vendor requirements.
• Origin requirements.

When governments require companies to change sourcing rapidly, businesses may encounter a gap between:

what regulation requires and what industry can actually supply.

That can create:

• Longer lead times.
• Higher prices.
• Project delays.
• Contract renegotiation.
• Supplier concentration.
• Production stoppages.

The risk is especially serious where alternative suppliers need testing, qualification or regulatory approval.

Global Impact

India has built approximately 200 GW of solar-module manufacturing capacity, but domestic solar-cell production is much smaller.

Government estimates put installed cell capacity at about 27 GW, while industry sources estimate effective operating capacity at only around 16–18 GW. Reuters reports that India still relies on China for around 95% of solar-cell imports.

That creates a mismatch.

India may have enough factories capable of assembling modules but insufficient domestic production of the component the new rules require them to use.

Government sources independently confirm that ALMM List II has been operationalised from 1 June 2026 and that covered projects must source listed domestic cells, subject to defined exemptions and transitional arrangements.

This demonstrates why policy-driven supply-chain changes need to be treated as an operational risk rather than merely a compliance exercise.

Our View

Businesses facing new sourcing requirements should calculate the capacity of the compliant supplier base before the regulation takes effect.

Companies should ask:

• How many approved suppliers actually exist?
• What is their genuine operating capacity?
• Is nameplate manufacturing capacity the same as available supply?
• How long are current lead times?
• Will competitors be seeking the same compliant suppliers?
• Are alternative products already qualified?
• Could a regulatory exemption apply?
• When does the transition period end?
• Are contracts flexible enough to accommodate regulatory delay?
• Who bears increased procurement costs?
• Does the business have inventory purchased before the rule change?
• Could several suppliers depend upon the same upstream foreign technology?

Diversification policy can ultimately increase resilience.

But during the transition, a business can move from many unrestricted suppliers to a very small pool of approved suppliers overnight.

That transition itself belongs on the risk register.
