EU Sets New EMC Test Rule for SiC/GaN Power Devices

On June 27, 2026, the European Commission released the amendment EN 55032:2026/A11:2026, introducing a new EMC compliance requirement for SiC and GaN power semiconductor modules and power systems imported into the EU. The new rule requires sub-microsecond transient immunity testing for DIP/INT and will become mandatory on July 1. For exporters, certification bodies, supply chain coordinators, and EU-facing customers, this matters because products without an updated CE-EMC certificate will not be able to clear customs, making certification timing and delivery schedules an immediate operational concern.

What the new amendment requires

According to the information provided, the amendment EN 55032:2026/A11:2026 was issued by the European Commission on June 27, 2026. It explicitly requires all SiC/GaN power semiconductor modules and power systems imported into the EU to pass a newly added sub-microsecond transient immunity test identified as DIP/INT. The requirement is scheduled for mandatory implementation on July 1. The same information also indicates that products lacking the updated CE-EMC certificate will not be able to complete customs clearance.

Where the impact is likely to be felt first

Export and market access teams face an immediate compliance checkpoint

From an industry perspective, direct exporters to the EU are likely to feel the earliest impact because the rule is tied to import clearance. The practical effect is not limited to laboratory testing itself; it also reaches certification planning, shipment readiness, and the timing of product release into the EU market. What deserves closer attention is whether existing certification paths for SiC/GaN modules and power systems can still support current delivery commitments once the new test becomes mandatory.

Manufacturers may see pressure on type approval and delivery scheduling

Analysis shows that manufacturers of SiC/GaN power semiconductor modules and related power systems may be affected through type approval workflows and shipment schedules. Because the information provided specifically mentions an impact on the certification path and lead time for Chinese exporters, production planning and export sequencing may need closer coordination with testing and documentation milestones.

Supply chain and service partners may need to manage document readiness more closely

Observably, service providers involved in certification support, customs preparation, and export delivery may also be affected. The immediate issue is not a change in product demand stated as fact, but a higher importance placed on whether compliance documents are complete and aligned with the new requirement before shipment. For businesses serving EU-bound orders, document readiness may become a gating item in execution.

EU-side buyers and procurement teams may focus more on certificate validity

From an industry perspective, procurement teams and downstream customers in the EU market may need to pay closer attention to whether suppliers hold the updated CE-EMC certificate under the revised requirement. The key business impact is likely to appear in order confirmation, shipment release, and delivery predictability rather than in product positioning alone.

What companies should watch now

Track the exact compliance wording and any follow-up clarification

Analysis shows that the immediate task for affected companies is to follow the formal wording of EN 55032:2026/A11:2026 and any subsequent official clarification related to the new DIP/INT test requirement. The reason is practical: small differences in interpretation can affect how a product is prepared for certification and when it can be shipped.

Review which EU-bound product lines fall within scope

What deserves closer attention is product scope. The information provided specifically refers to SiC/GaN power semiconductor modules and power systems imported into the EU. Companies handling multiple categories should identify which export items are exposed to the new requirement and whether those items are tied to near-term deliveries.

Recheck certification documents against delivery commitments

Observably, the gap between a policy requirement and day-to-day shipment execution often appears in documentation timing. Since products without the updated CE-EMC certificate will be unable to clear customs, companies should closely align certificate status, shipment schedules, and customer delivery commitments. This is especially relevant where orders are already in motion.

Prepare customer and supplier communication around lead time risk

From an operational perspective, companies may need clearer communication with testing partners, suppliers, and customers regarding possible effects on approval timing and delivery windows. The information provided already points to an impact on certification routes and lead time, so communication planning is part of risk control rather than a secondary task.

Why this reads as more than a routine technical update

Analysis shows that this development should not be read only as a narrow laboratory adjustment. Because the new requirement is linked directly to customs clearance, it moves EMC compliance from a technical checkpoint into a market access condition for affected SiC/GaN products. At the same time, based strictly on the information provided, it is more appropriate to understand this as a confirmed short-term regulatory change with broader operational implications still requiring observation, rather than as a basis for wider market conclusions.

How to read the signal at this stage

At this stage, the clearest industry meaning is that compliance timing has become a near-term business issue for EU-bound SiC/GaN modules and power systems. The confirmed facts support a practical conclusion: companies exposed to the EU market should treat the new EMC testing requirement as an immediate execution matter affecting certification, customs clearance, and delivery planning. Beyond that, longer-range effects on competition, sourcing, or product strategy still need continued observation rather than firm conclusions.
