Colombia Upholds Anti-Dumping Duties on Chinese Acrylic Sheets

On April 28, 2026, Colombia’s Ministry of Commerce, Industry and Tourism issued Resolution No. 148, confirming the continuation of anti-dumping duties on imported acrylic sheets (láminas de acrílico) from China following the first sunset review. This decision directly affects manufacturers and integrators of cold storage systems—particularly those relying on Chinese-sourced acrylic components for transparent viewing windows, temperature-control panels, and cleanroom observation panels.

Event Overview

On April 28, 2026, Colombia’s Ministry of Commerce, Industry and Tourism published Resolution No. 148, announcing a positive final determination in the first sunset review of the anti-dumping measures originally imposed on acrylic sheets originating from China. The review concluded that termination of the duties would likely lead to continuation or recurrence of dumping and injury to the domestic industry. As a result, the existing anti-dumping duties remain in force.

Industries Affected by This Decision

Direct Exporters of Acrylic Sheets

Chinese producers and exporters of acrylic sheets supplying the Colombian market face continued tariff barriers. The upheld duties increase landed costs, potentially reducing competitiveness against regional or alternative suppliers.

Cold Storage System Integrators

Integrators sourcing acrylic panels from China for cold room doors, control panels, or observation windows will experience higher component procurement costs. This may compress margins or necessitate price adjustments in downstream contracts.

Component-Level Manufacturers & Assemblers

Firms fabricating finished cold storage vision components—including cut-to-size, edge-finished, or laminated acrylic units—rely on cost-competitive Chinese sheet imports. Sustained duties raise raw material input costs and could delay project timelines if alternative sourcing requires requalification.

Supply Chain & Procurement Managers in Latin America

Regional procurement teams responsible for cold storage infrastructure projects must now reassess supplier diversification strategies. The decision accelerates ongoing shifts toward local co-packing, private-label arrangements, or sourcing from Southeast Asian suppliers—not as contingency plans, but as operational necessities.

Key Considerations and Practical Responses for Stakeholders

Monitor Official Implementation Guidance and Customs Classification Updates

Resolution No. 148 confirms duty continuation but does not specify revised tariff line applications or enforcement thresholds. Stakeholders should track subsequent notices from Colombia’s National Tax and Customs Directorate (DIAN) regarding Harmonized System (HS) code alignment, valuation methodology, and documentation requirements for acrylic sheet imports.

Review Exposure Across Product Categories and End-Use Applications

Not all acrylic-based cold storage components fall under the scope of ‘láminas de acrílico’ as defined in the resolution. Companies should verify whether their specific products—including laminated, coated, or thermoformed variants—remain within the scope. Clarification may require consultation with Colombian customs brokers or legal counsel specializing in trade defense instruments.

Distinguish Between Policy Signal and Operational Impact

The sunset review outcome reflects a policy-level decision—not an immediate customs action. Actual impact depends on enforcement rigor, importer compliance behavior, and potential appeals or WTO consultations. Businesses should treat this as a confirmed risk factor, not an automatic disruption trigger.

Update Sourcing Plans and Qualify Alternative Suppliers Without Delay

Given the confirmed extension, companies dependent on Chinese acrylic sheets for Colombian-bound cold storage systems should initiate dual-sourcing validation now—not after shipment delays occur. Prioritize qualification of suppliers in Mexico, Vietnam, or Thailand where product specifications and certifications (e.g., ISO 7823-1, ASTM D4280) align with cold storage application requirements.

Editorial Perspective / Industry Observation

Observably, this decision signals consolidation—not escalation—of existing trade remedies. It confirms Colombia’s intent to maintain structural safeguards for its domestic polymer sheeting sector, rather than introducing new restrictions. Analysis shows the ruling is less about targeting Chinese exports per se and more about preserving established import discipline in a high-value niche segment. From an industry perspective, it reinforces that cold storage component supply chains operating across Latin America can no longer treat Chinese-sourced acrylic as a default low-cost option without tariff contingency planning. The review outcome functions primarily as a formalized risk anchor: it validates assumptions held by forward-looking integrators since the original measure was imposed, and makes previously speculative diversification efforts operationally urgent.

Colombia’s decision underscores how trade defense instruments increasingly shape engineering-grade material flows—not just bulk commodities. For cold storage system providers, transparency in regulatory exposure matters as much as optical clarity in their acrylic windows.

This development is not an isolated tariff event, but a marker of maturing regional trade governance in technical building materials. It reflects growing scrutiny of upstream inputs in climate-controlled infrastructure—where material certification, traceability, and landed cost predictability are converging as strategic priorities.
