Colombia’s automotive industry is facing a crucial regulatory shift. The Ministry of Commerce, Industry, and Tourism (MINCIT) has published a draft decree aiming to extend the Mechanism for the Stimulus of the Automotive Sector (IAMAS). This mechanism is vital for assembly plants and manufacturers seeking to preserve competitiveness and lower operational costs within their global supply chains.
If your company operates in automotive manufacturing or you are currently evaluating foreign investment opportunities in the country, understanding the scope of this extension is critical. This article breaks down how the benefit works, its impact on import costs, and the operational risks you must watch out for in your logistics and customs planning for the coming years.
What is the IAMAS tariff benefit and who qualifies?
The IAMAS mechanism is an industrial policy tool designed by the Colombian government. Its primary objective is to exempt specific vehicles and assembly components from customs duties (0% tariff), provided that companies meet explicit local investment, manufacturing, and technological development requirements.
Who can access this incentive?
This benefit is not open to general vehicle importers. It is strictly targeted at:
-
Assembly plants authorized under Colombia’s transformation or assembly regime.
-
Component manufacturers that are part of the local production supply chain.
-
International investors planning to establish automotive manufacturing plants or clean mobility technology projects in the country.
The new draft decree: Extension and clean energy focus
The recent draft decree from MINCIT seeks to extend the legal life of this benefit. The government recognizes that the automotive industry requires long-term regulatory stability to write off heavy capital investments.
What are the key points of the proposal?
-
Support for local production: It ensures domestic plants remain competitive against fully assembled imported vehicles.
-
Focus on clean technologies: It prioritizes incentives for hybrid and electric vehicles, as well as units featuring high road-safety standards.
-
Timeline adjustment to be confirmed: The document proposes a five-year extension starting December 31, 2026. However, the draft contains a technical contradiction, as it simultaneously mentions a deadline of December 31, 2028. This is a critical point that the private sector is asking to clarify before the presidential signature.
How does the 0% tariff import process work under IAMAS?
To clear customs and apply the IAMAS benefit to imported goods, companies must complete a rigorous process before both DIAN (the Colombian tax and customs authority) and MINCIT:
-
Registration and prior approval: The company must be registered and approved as an authorized manufacturing or assembly industry by the Ministry.
-
Compliance with performance requirements: Importers must prove they meet agreed local auto-part integration levels or investment quotas.
-
Specific customs clearance: When filing the Import Declaration, the exact customs exemption code tied to the IAMAS decree must be declared.
Customs Warning: A minor classification error or an expired supporting document can cancel the benefit, forcing your company to pay full tariffs (which can reach up to 35%) plus severe penalties for inaccuracy.
Common mistakes companies make with Colombian tariff benefits
-
Documentary discrepancies: The description of the vehicles or CKD (Completely Knocked Down) kits on the commercial invoice or bill of lading failing to match the IAMAS authorization exactly.
-
Misjudging approval timelines: Government processing times can take weeks. If cargo arrives at a Colombian port before the official resolutions are ready, it will trigger expensive port storage and container demurrage fees.
-
Relying blindly on draft texts: Planning inventory purchases based on preliminary drafts without tracking the final text published in the Official Gazette (Diario Oficial).
Strategic advice for procurement and logistics managers
If your operations rely on this benefit, we recommend taking the following preventive measures:
-
Audit your tariff classification matrix: Ensure the specific subheadings you plan to import over the next two years are explicitly covered by the extended decree.
-
Monitor the final decree text: Work closely with a 4PL logistics partner or customs broker to track how the 2026 vs. 2028 timeline discrepancy is ultimately resolved in the final version.
-
Plan for financial scenarios: Evaluate the cash flow impact in case the signing of the decree faces delays, which would require posting customs bonds to clear the cargo without paying immediate duties.
The proposed extension of the IAMAS benefit is excellent news for the stability of the automotive sector and a positive signal for investors looking at Colombia as a regional production hub. However, the success of this tax relief depends entirely on flawless customs execution. A single oversight in license management or port clearance can turn a 0% tariff opportunity into a major financial contingency.

Frequently Asked Questions
What does the IAMAS benefit mean for the Colombian automotive sector?
It stands for the Mechanism for the Stimulus of the Automotive Sector. It allows authorized assembly and manufacturing industries in Colombia to import vehicles and components with a 0% tariff, promoting local investment and employment.
When does the new IAMAS decree extension take effect?
The draft decree proposes extending the benefit starting December 31, 2026. However, the private sector and authorities are currently clarifying the final wording due to a technical inconsistency in the text that also references the year 2028.
What happens if I import automotive goods without fulfilling IAMAS requirements?
If you lack MINCIT authorization or fail to meet the program’s requirements, you must clear customs by paying the general tariff applicable to the automotive sector, which ranges between 5% and 35% depending on the type of vehicle and its country of origin.
