Polyoxymethylene, also known as POM or acetal, is an important engineering plastic used in many everyday products. It is strong, durable, and resistant to wear, which makes it suitable for automotive parts, electrical components, consumer goods, gears, and industrial applications. Because it plays such a key role in manufacturing, changes in its pricing are closely watched by buyers, suppliers, and manufacturers around the world.

As of Q3 2025, the global Polyoxymethylene price trend has shown a generally positive direction. In simple terms, prices have mostly increased across major regions. The rise has not been dramatic, but steady. In most key markets, POM prices have increased between 2% and 3.5% compared to the previous quarter. This steady movement reflects balanced supply and demand, stable feedstock costs, and continued confidence in the market.

Let’s take a closer look at how the Polyoxymethylene price trend developed across different regions during the third quarter of 2025.

Overall Global Market Situation

In Q3 2025, the global POM market remained relatively stable. Supply levels were adequate in most regions, and there were no major production disruptions. Feedstock prices, especially for formaldehyde and acetal intermediates, remained stable. When raw material costs do not fluctuate significantly, it helps maintain price stability in the finished product.

Demand was also steady in many countries. While there was no sudden surge in buying activity, procurement remained consistent. This balanced environment helped support gradual price increases rather than sharp spikes. Overall, global Polyoxymethylene price trends maintained a firm tone throughout the quarter.

South Korea: Strong and Steady Growth

In South Korea, the Polyoxymethylene price trend was clearly positive. Export prices from FOB Busan for Low Viscosity Copolymer GPIM (MFR:27) ranged between USD 1630 and 1640 per metric ton. This represented a 3.5% increase compared to Q2 2025.

The main reason behind this growth was firm regional demand combined with stable supply conditions. Summer demand and seasonal effects supported procurement activity. Buyers from other Asian countries continued to place orders steadily, which helped maintain a strong market tone.

Feedstock prices remained stable, providing additional support to POM prices. Since raw material costs were not volatile, producers were able to maintain consistent pricing strategies. In September 2025, prices remained largely stable, with a modest 0.6% improvement compared to previous months. By the end of Q3, the market in South Korea confirmed a firm and confident tone.

Thailand: Positive Momentum with Minor Adjustment

Thailand also experienced a positive Polyoxymethylene price trend during Q3 2025. Export prices from FOB Laem Chabang increased by an average of 1.8% compared to the previous quarter.

Demand in the region remained consistent, and procurement activity was steady. Feedstock costs stayed stable, which supported seller confidence. Competitive pricing and balanced supply levels helped ensure smooth transactions across the quarter.
