For any business importing electrical equipment, machinery, or components into Colombia, navigating technical regulations is often the most critical step in the nationalization process. A minor misunderstanding of local compliance can lead to costly delays at the port, unexpected storage fees, or even the rejection of your import declaration.

With the entry into force of Resolution 40284 of June 23, 2026, which modifies the Technical Regulation of Electrical Installations (RETIE), the Colombian government has updated the rules of the game. This article breaks down what these regulatory changes mean for your import operations, how to determine if your product actually requires a RETIE certificate, and how to protect your supply chain from regulatory bottlenecks.

What is Resolution 40284 of 2026 and Why Does It Matter?

Resolution 40284 of June 23, 2026, was enacted by the Ministry of Mines and Energy to modify RETIE after an extensive technical review, sector feedback, and collaborative workshops. The primary goal of this update is to correct drafting errors, adjust technical definitions, clarify exceptions, and optimize conformity assessment processes without making procedures more burdensome for regulated companies.

For Colombian importers and foreign investors, this resolution is highly beneficial because it provides greater regulatory clarity, reducing arbitrary interpretations during customs inspections.

The Big Shift: Tariff Subheadings No Longer Solely Determine RETIE

Historically, one of the most common friction points in Colombian customs was the automatic assumption that if an import fell under a specific HS code (subpartida arancelaria), it automatically required a RETIE certificate.

Resolution 40284 of 2026 explicitly corrects this practice. The regulation now states that tariff subheadings alone do not determine whether a product is subject to RETIE. Instead, customs authorities, importers, and customs agents must analyze each product individually based on the following criteria:

• Nature of the product: What is the product made of, and how does it function?
• Technical characteristics: What are its specific parameters (voltage, insulation, etc.)?
• Intended use: Where and how will it be installed or operated?
• Scope of the regulation: Does the product fall under the legitimate safety objectives of RETIE?

The Colombian Context: If you are importing specialized industrial machinery that includes minor electrical components under a broad, generic tariff subheading, the DIAN (Colombian Customs) can no longer demand a RETIE certificate based solely on the HS code. If the technical specifications prove the product falls outside the scope of RETIE, it is exempt.

Are You a “Producer” Under Colombia’s RETIE?

Under Article 1.2.1 of the updated regulation, any entity acting as an importer is legally classified as a “Productor para Colombia” (Producer for Colombia). This definition includes any individual or corporation that habitually, directly or indirectly, manufactures, assembles, or imports products subject to the technical regulation.

As an importer, you carry the ultimate legal responsibility to guarantee that the imported goods conform to RETIE standards. This means you must ensure that all conformity assessments, test reports, and certificates are valid and authenticated before the cargo arrives at Colombian ports.

Key Technical Definitions to Check Before Importing

Before placing an order with your international suppliers, your engineering and logistics teams should verify if the equipment meets or is exempt from the regulation based on these updated definitions:

1. Low-Voltage Contact Limits (Límite de contacto de baja tensión)

If your equipment operates under very low voltage, it may not trigger RETIE requirements. The updated rule defines this limit as a voltage not exceeding:

• 15 V RMS for sinusoidal AC.
• 21.2 V peak for non-sinusoidal AC.
• 30 V for continuous DC.

2. “Own Installation” Exclusions (Instalación propia)

The regulation defines an “own installation” as one comprised exclusively of the components and equipment essential for its own operation, excluding external power supply systems, independent substations, or distribution boards used to energize other systems. Clarifying whether your machinery qualifies as an own installation can simplify your compliance strategy.

Common Mistakes Importers Make with RETIE

• Relying solely on the supplier’s word: Many foreign manufacturers claim their products are “CE” or “UL” certified, but these certificates must be properly aligned with Colombian conformity schemes and recognized by ONAC (National Accreditation Body of Colombia) to be valid at customs.
• Ignoring the International System of Units (SI): Colombia strictly enforces the SI. All technical documentation, labeling, and manuals must use official symbols (e.g., $V$ for volts, $A$ for amperes, $\Omega$ for ohms) exactly as outlined in the regulation, avoiding non-standard abbreviations.
• Overlooking mandatory Spanish labeling: Product safety warnings and technical plates must be written in Spanish and clearly visible.

Recommendations for a Seamless Import Process

To avoid delays, demurrage fees, and customs penalties, Siacomex recommends implementing a proactive compliance protocol:

1. Conduct a Pre-Shipment Technical Analysis: Do not wait for the container to arrive at the port. Work with your customs broker and logistics provider to review the product’s technical sheets, testing methods, and intended use against the 2026 RETIE standards.
2. Engage an Integrated 4PL Logistics Partner: A 4PL provider does more than move cargo; they coordinate technical compliance at origin, ensuring the correct labeling, symbols, and documentation are applied before export.
3. Verify Certification Schemes Early: Ensure your manufacturer’s test reports (such as type tests or routine tests) are issued by accredited laboratories and can be easily validated or homologated in Colombia.

The update introduced by Resolution 40284 of 2026 is a major step forward for Colombian trade. By decoupling RETIE compliance from tariff subheadings alone, the Ministry of Minas y Energía has reduced unnecessary trade barriers. However, this change shifts the burden of proof to the importer, who must now technically justify whether a product is regulated. Early analysis, robust technical documentation, and strategic partnership with customs experts are the best defenses against supply chain disruptions.

1. Does my imported product need a RETIE certificate if its HS code is on the RETIE list?

Not necessarily. Resolution 40284 of 2026 establishes that tariff subheadings do not solely determine compliance. You must analyze the product’s specific nature, technical features, and usage to determine if it truly falls under the scope of the regulation.

2. Can I use a foreign certificate (like UL or CE) to clear RETIE at Colombian customs?

Foreign certificates are not automatically accepted. To clear customs, they must be issued under a valid conformity assessment scheme and, if applicable, homologated or recognized by a Colombian certification body accredited by ONAC.

3. Who is legally responsible for RETIE compliance on imported goods?

The importer is legally considered the “Producer for Colombia” (Productor para Colombia). Therefore, the Colombian importer is solely responsible for ensuring the goods comply with the technical requirements and hold valid conformity certificates.

4. Does the new RETIE apply to Solar Photovoltaic Systems (SSFV)?

Yes, RETIE covers all equipment and products used in generation, transmission, distribution, and end-use of electrical energy. Imported components for solar energy projects must comply with the specific safety and technical requirements set by the regulation.
