Colombia Upholds Anti-Dumping Duties on Acrylic Sheets from China

On April 28, 2026, Colombia’s Ministry of Commerce, Industry and Tourism issued Resolution No. 148, affirming the continuation of anti-dumping duties on acrylic sheets originating in China following the first sunset review. This decision directly affects manufacturers and exporters supplying components for Vision AI enclosures, smart glasses frames, and intelligent lighting diffusers — sectors increasingly reliant on precision-molded acrylic aesthetics and optical clarity.

Event Overview

On April 28, 2026, Colombia’s Ministry of Commerce, Industry and Tourism published Resolution No. 148, concluding the first sunset review of the anti-dumping measures on acrylic sheets from China with an affirmative determination. The existing anti-dumping duties — ranging from 12.4% to 41.8% — will remain in force. The measure applies specifically to flat, transparent or tinted acrylic sheets (polymethyl methacrylate, PMMA), as defined under the Colombian customs tariff classification relevant to the original investigation.

Industries Affected by Segment

Direct Exporters (Chinese Manufacturers & Trading Companies)

These entities face sustained cost pressure on shipments to Colombia. The upheld duties directly reduce export competitiveness and narrow margin buffers, especially for mid-tier suppliers competing on price in a market where local distributors increasingly prioritize landed-cost transparency.

Component Integrators (OEMs/ODMs of Vision AI Devices & Wearables)

Firms sourcing acrylic panels for end-product assembly — particularly those building Vision AI housings, AR/VR eyewear frames, or smart lighting fixtures — now confront higher input costs when importing finished or semi-finished acrylic parts from China. This may trigger reassessments of regional sourcing strategies or material substitution timelines.

South America–Based Assemblers & Local Contract Manufacturers

With duties reinforcing import cost disadvantages, local or nearshored injection molding service providers in Colombia or neighboring countries may see increased inbound inquiries for acrylic part production. However, capacity constraints and tooling lead times mean short-term shifts remain limited to high-value or low-volume SKUs.

Distribution & Channel Partners Serving LATAM Markets

Importers and distributors handling acrylic-based subassemblies must revise landed-cost calculations and adjust pricing models for downstream OEM customers. Margin compression is most acute for standardized, high-turnover items where duty pass-through is operationally unavoidable.

What Relevant Enterprises Should Monitor and Do Now

Track official implementation guidance and classification clarifications

The Ministry’s resolution confirms duty continuation but does not reissue detailed product scope language. Enterprises should monitor subsequent administrative notices — particularly any updated Harmonized System (HS) code interpretations or exclusions — which could affect borderline items such as co-extruded or metallized acrylic sheets.

Assess exposure by product category and shipment pattern

Not all acrylic sheet forms carry equal risk: thickness, surface treatment (e.g., anti-reflective coating), and intended end-use (e.g., structural vs. optical-grade) may influence tariff application. Firms should audit current Colombian-bound SKUs against the original investigation’s scope annexes — not just HS codes — to identify potential reclassification opportunities.

Distinguish between policy signal and operational impact

This is a definitive continuation of an existing measure — not a new investigation or rate increase. Its primary effect is predictability (duties remain) rather than escalation (no new rates). Operational planning should therefore focus on cost absorption, logistics timing, and documentation compliance — not emergency mitigation.

Prepare for upstream and downstream communication alignment

Exporters should proactively share updated commercial invoices and origin documentation with Colombian buyers to support their customs clearance. Buyers, in turn, may request revised Incoterms (e.g., shifting from FOB to DAP) to clarify duty liability. Joint alignment on documentation standards reduces clearance delays at Colombian ports.

Editorial Perspective / Industry Observation

Observably, this sunset review outcome signals Colombia’s continued prioritization of domestic polymer processing capacity — even amid broader trade liberalization efforts in the Andean region. Analysis shows the decision reflects institutional consistency rather than reactive protectionism: the same duty range has applied since the original 2019 measure, and no new injury evidence was introduced during the review. From an industry standpoint, it reinforces that acrylic sheet trade with Colombia is now operating within a stable, albeit constrained, regulatory framework — one where supply chain resilience hinges less on tariff volatility and more on localization readiness and technical compliance rigor.

Current developments are best understood as a consolidation of existing trade conditions — not a turning point. The absence of rate adjustments or scope expansion suggests Colombian authorities view the current regime as sufficient to address prior findings of material injury. Continued monitoring remains prudent, particularly ahead of the next scheduled sunset review (expected circa 2031), but near-term strategic emphasis should be placed on operational adaptation rather than anticipatory restructuring.

In summary, Colombia’s reaffirmation of anti-dumping duties on Chinese acrylic sheets formalizes a persistent cost factor for exporters and integrators serving the South American tech hardware market. It underscores the growing importance of tariff-aware procurement design, regional compliance literacy, and cross-border documentation discipline — not as contingency measures, but as baseline operational competencies.
