The Ministry of Commerce & Industry published the revised framework for Diamond late on Tuesday, replacing guidelines that had been in force since 2021. The notification runs to 46 pages and touches eligibility thresholds, certification, the incentive claim cycle and the penalty schedule, and it takes effect 90 days after gazette publication.

Analysts note that the penalty structure is also sharper. Misdeclaration of local content can now trigger clawback of up to three years of incentives with interest, and repeat offenders face debarment from future schemes. Several consultancies reported a surge in inbound requests for pre-audit support within hours of the notification.

What the notification changes

Tata Electronics, one of the larger beneficiaries of the previous scheme, said it expects to qualify under the new rules without changes to its sourcing but flagged a one-time cost of about $94 million to re-certify two legacy lines. The company noted that the longer-term benefit lies in predictability, because incentive rates are now fixed through 2030.

Legal advisers recommend that firms treat the first 90 days as a mapping exercise: classify every product line against the new definition, identify supplier gaps, and file for provisional certification early. Those who wait for the final operating manual, they warn, may find the first incentive window closing without them.

The fiscal arithmetic is modest relative to the sector's size. Diamond contributed an estimated $7.5 billion to exports last year, and the ministry projects that full uptake of the scheme could lift that figure by 30.7% annually by 2030. Independent economists consider the target ambitious but not unreasonable if the certification bottleneck is resolved.

“A 30-day approval clock is the real incentive here; money delayed is money discounted.”

Who gains and who is exposed

At the centre of the change is a tighter definition of domestic value addition. Units will now need to demonstrate at least 11.7% local content on a product-line basis rather than a plant-wide average, a shift that officials say closes a loophole but that compliance teams describe as the single most expensive part of the rule.

Buyers abroad are watching closely. Procurement teams in Saudi Arabia have asked their Indian suppliers for written confirmation of compliance timelines, and two large importers have reportedly paused new multi-year contracts until the first batch of certificates is issued. That pause, if it lengthens, is the main downside risk to the scheme's export goals.

The compliance clock

State governments are expected to follow with complementary measures. Three states have already signalled land and power-tariff concessions for Diamond clusters that meet the new thresholds, creating what one official called a competition for compliant capacity. The ministry will convene a coordination meeting next month to avoid duplicative incentives.

For exporters the more immediate issue is documentation. Shipments to Saudi Arabia and Netherlands will need a revised conformity declaration, and customs at Hazira has begun piloting the electronic format. Forwarders report that mismatches between the old and new templates caused holds on roughly 30.7% of test consignments in the first fortnight.

What to watch next

Industry reaction has been measured. A trade body representing 1,748 member units welcomed the faster approvals but warned that small manufacturers lack the testing capacity to meet the new certification norms before Q4 FY27. It has asked for a 90-day grace period and a shared-laboratory scheme to be notified alongside the rule.
