EU Sets EMC Tests for SiC/GaN Power Devices from July 1

From July 1, 2026, the EU will apply a new mandatory EMC radiated emission testing requirement to wide-bandgap semiconductor power devices, bringing SiC MOSFET and GaN HEMT products within the scope of EN IEC 61000-6-3:2025 Annex D for industrial and automotive-grade modules entering the EU market. This is worth close attention because it does not merely add a technical reference; it affects CE compliance pathways, test scheduling, supplier qualification review, and delivery planning for exporters, importers, and downstream buyers connected to the power semiconductor trade.

What the rule change formally covers

The confirmed facts are limited but clear. The European Commission issued amending regulation (EU) 2026/1189 on June 26, 2026. Under that change, wide-bandgap semiconductor power devices, including SiC MOSFET and GaN HEMT products, are brought into the mandatory EMC radiated emission testing scope set out in EN IEC 61000-6-3:2025 Annex D. The requirement applies to all industrial and automotive-grade modules placed on the EU market, and its implementation date is July 1, 2026. The information provided also states that the change directly affects the CE certification route and testing timeline of Chinese export-oriented power semiconductor manufacturers, while importers need to reassess supplier compliance qualifications and lead times.

Where the immediate pressure points are likely to appear

Export compliance moves closer to the front of the shipment cycle

From an industry perspective, exporters of SiC and GaN power modules are likely to feel the impact first because the new requirement is tied to market access and certification handling. The practical pressure point is not only the test itself, but the sequencing of compliance work before products move into EU sales channels. What deserves closer attention is whether existing CE preparation files, testing arrangements, and release schedules are still sufficient once radiated emission testing becomes a mandatory step for the covered products.

Importers face a stricter supplier review task

For EU importers and procurement teams, the issue is less about product marketing and more about supplier readiness. The information provided already indicates that supplier compliance qualifications and delivery timing need to be reassessed. In practical terms, importers are likely to focus more closely on whether suppliers can present valid compliance documentation, whether testing status matches the new rule, and whether previously expected delivery commitments remain realistic under the revised certification path.

Testing and certification-related service providers may see workflow changes

Analysis shows that laboratories, certification support firms, and compliance service providers connected to power semiconductor exports may also be affected because the rule changes the required testing scope for covered modules. The key business effect is likely to appear in document review, test planning, and certification coordination. Even without further execution details, the market signal is that EMC-related verification for these products will need closer alignment with the updated EU requirement.

Downstream buyers may need to recheck procurement and project timing

Industrial and automotive buyers using covered modules may also need to revisit procurement assumptions. Observably, when a new mandatory test enters the path to market, the effect can extend into order confirmation, technical file review, and expected delivery windows. The point to watch is not a proven shortage or disruption, which has not been established, but a higher need to confirm that compliance status and shipment timing remain aligned.

What companies should review now

Recheck the current CE compliance path

Analysis shows that manufacturers supplying the EU market should first verify whether their present CE documentation and testing workflow fully reflect the new mandatory EMC radiated emission requirement for the covered product scope. This should be treated as a compliance review point rather than an assumption that prior files remain sufficient.

Match technical documents with the revised testing scope

What deserves closer attention is the consistency between product definitions, technical documents, and test evidence. For exporters and importers alike, the practical issue is whether product files, declarations, and supporting materials clearly correspond to the updated mandatory testing scope now tied to EN IEC 61000-6-3:2025 Annex D.

Reassess lead times in procurement and delivery planning

Observably, the provided information already points to testing-cycle pressure and lead-time reassessment. Companies involved in procurement, sales operations, and supply chain planning should therefore review whether quoted delivery dates, buffer times, and supplier commitments still reflect the new compliance sequence. This is especially relevant where shipments depend on certification completion before placement on the EU market.

Watch for how the requirement is reflected in market documents

It is more appropriate to understand this as an area requiring follow-up rather than a fully mapped execution framework. Companies should pay attention to how the new requirement appears in certification communications, customer document requests, procurement specifications, and other transaction-facing materials. The input does not provide detailed enforcement language, so this remains a monitoring point rather than a confirmed outcome.

Why this looks like an implementation signal, not just a policy headline

Analysis shows that this development is better understood as a rule already moving into execution rather than a distant policy discussion, because an implementation date of July 1, 2026 is explicitly given and the covered testing scope is identified. At the same time, it would be premature to treat all market consequences as settled. Observably, the current information is enough to confirm a compliance change and its likely effect on certification paths and timing, but not enough to establish a uniform market response, detailed enforcement practice, or a final operational standard across every transaction scenario.

How to read the significance of this update

The significance of this update lies in its practical effect on market access procedures for covered power semiconductor modules entering the EU. It is more appropriate to understand this as a concrete compliance change with direct operational implications for certification, supplier review, and delivery planning, while still recognizing that execution details and market adaptation will need continued observation. For the industry, the immediate task is not speculation about broader outcomes, but disciplined attention to compliance files, test arrangements, and procurement coordination under the new requirement.
