ANATEL Tightens EMC Rules for GIS Switchgear

Brazil’s National Telecommunications Agency (ANATEL) brought Resolution No. 821/2026 into effect on July 13, 2026, adding a new IEC 61000-4-30 Class A radio interference limit for intelligent terminal modules integrated into GIS switchgear. For Chinese exporters, this is not just a documentation update: it directly affects product configuration, component selection, and certification readiness, because equipment without an INMETRO-certified Class A filter at the power input and a supporting EMC test report cannot obtain the ANATEL certification label.

What the New Rule Requires

The confirmed change is tied to GIS switchgear that includes integrated intelligent terminal modules. Under Resolution No. 821/2026, effective July 13, 2026, ANATEL introduced a new IEC 61000-4-30 Class A radio interference limit for these modules. The provided information also makes clear that Chinese export companies must install an INMETRO-certified Class A filter at the equipment power input and submit an EMC test report. Without these items, the product cannot receive the ANATEL certification label.

Where the Impact Will Be Felt First

Export-facing equipment makers will face immediate design and certification pressure

From an industry perspective, manufacturers shipping GIS switchgear to Brazil are the first group affected because the requirement is tied to both hardware configuration and certification evidence. The impact is likely to appear in product design review, bill-of-material decisions, pre-shipment compliance checks, and certification submission workflows.

Component sourcing teams need to focus on filter compliance status

For procurement and sourcing functions, the key issue is not only whether a Class A filter is installed, but whether that filter is INMETRO-certified as required in the provided information. This means supplier qualification, part selection, and incoming compliance documentation become more sensitive points in the export process.

Testing and certification service providers may see tighter documentation demands

Observably, laboratories, compliance teams, and certification service providers are also likely to be affected because the rule explicitly links ANATEL labeling to EMC test reporting. The operational focus here is likely to shift toward test scheduling, report completeness, and alignment between the installed filter configuration and the certification file.

Brazil-bound buyers and channel partners may pay closer attention to delivery readiness

Distributors, project buyers, and downstream commercial partners involved in Brazil-bound deliveries may need to watch whether products are certification-ready before shipment. The practical concern is not theoretical compliance but whether the equipment can move through market access steps without delay caused by missing filter certification or incomplete EMC evidence.

What Companies Should Check Now

Confirm which exported configurations fall within the scope

What deserves closer attention is whether the exported GIS switchgear includes the integrated intelligent terminal modules covered by the stated requirement. Companies should distinguish between affected and unaffected configurations based only on the rule elements provided, because the compliance obligation is linked to that specific product integration.

Review filter sourcing against certification evidence

Businesses should verify whether the Class A filter planned for the power input already carries the required INMETRO certification. In practice, this is a supplier-document issue as much as a technical issue, and any mismatch between installed parts and certification expectations could create problems at the ANATEL labeling stage.

Prepare EMC reports as part of the certification package

The need to provide an EMC test report means compliance work cannot stop at hardware modification. Companies should examine whether existing reports match the actual export configuration, especially where the filter becomes a mandatory installed element rather than an optional accessory.

Separate the legal requirement from internal assumptions

Analysis shows that one practical risk is treating the rule as a general market signal without checking the exact filing consequences described in the provided information. The confirmed point is straightforward: without the certified filter and EMC report, the ANATEL certification label cannot be obtained. Internal planning should stay anchored to that stated condition.

Why This Matters Beyond a Single Filing Step

As an editorial observation, this update is more appropriate to understand as a concrete compliance trigger rather than a broad market trend on its own. The immediate effect is clear in certification terms, but the wider industry meaning lies in how technical components, test evidence, and market-access labeling are being tied more tightly together for products that combine power equipment with intelligent modules.

Analysis also shows that this is not merely a short-term paperwork adjustment. Even based only on the confirmed information, the rule pushes exporters to manage compliance earlier in the product and supply chain process, especially where component certification and EMC reporting must line up before market entry.

How to Read the Update at This Stage

The most balanced reading is that ANATEL’s July 13, 2026 change creates an immediate operational requirement for Chinese exporters of affected GIS switchgear, while also signaling a stricter compliance threshold for integrated intelligent modules. It is too early to treat this alone as a broad restructuring of the market, but it is already specific enough to require action in design review, sourcing, testing, and certification preparation.
