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 45 days after gazette publication.

Legal advisers recommend that firms treat the first 45 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.

What the notification changes

Buyers abroad are watching closely. Procurement teams in Vietnam 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.

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.

The fiscal arithmetic is modest relative to the sector's size. Diamond contributed an estimated $5.6 billion to exports last year, and the ministry projects that full uptake of the scheme could lift that figure by 28% annually by 2029. Independent economists consider the target ambitious but not unreasonable if the certification bottleneck is resolved.

“Predictability matters more than the headline rate. Boards will commit capital when the rules are fixed for five years.”

Who gains and who is exposed

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.

The next milestone is the release of the operating manual and the online portal, which the ministry says will arrive within six weeks. Until then, firms are advised to rely on the frequently-asked-questions document that accompanied the notification, which already answers 38 of the questions raised during stakeholder consultation.

The compliance clock

Industry reaction has been measured. A trade body representing 1,346 member units welcomed the faster approvals but warned that small manufacturers lack the testing capacity to meet the new certification norms before Q3 FY27. It has asked for a 90-day grace period and a shared-laboratory scheme to be notified alongside the rule.

At the centre of the change is a tighter definition of domestic value addition. Units will now need to demonstrate at least 17.8% 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.

What to watch next

For exporters the more immediate issue is documentation. Shipments to Vietnam and Netherlands will need a revised conformity declaration, and customs at Chennai has begun piloting the electronic format. Forwarders report that mismatches between the old and new templates caused holds on roughly 28% of test consignments in the first fortnight.
