Polyoxymethylene Price Trend: A Simple and Clear Overview of Q3 2025

 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.

However, in September 2025, prices in Thailand eased slightly by 1.9% compared to August. This small adjustment was mainly due to moderate demand and sufficient inventory levels. Despite this monthly dip, the overall quarterly trend remained positive and stable.

Vietnam: Stable Imports with Slight Monthly Dip

In Vietnam, Polyoxymethylene import prices at CIF Haiphong from Thailand increased by 1.8% in Q3 2025. The Polyoxymethylene price trend here was supported by steady imports and balanced supply conditions.

Vietnam relied on regular shipments from Thailand, which ensured stable availability. Procurement activity remained fairly consistent throughout the quarter. Feedstock costs were stable, which further supported market confidence.

In September 2025, prices declined slightly by 1.9% compared to August due to moderate demand and adequate inventory levels. Even so, the general tone of the market remained firm for the quarter. Balanced fundamentals helped prevent sharp fluctuations.

India: Slight Downward Adjustment

India was one of the few markets where the Polyoxymethylene price trend moved slightly downward during Q3 2025. Domestic prices Ex-Delhi decreased by about 1.29% compared to the previous quarter.

The main reason for this decline was reduced domestic demand and sufficient inventory levels. Buyers were cautious, and consumption remained moderate. Since supply was stable and inventory levels were comfortable, there was no strong reason for prices to rise.

Feedstock costs remained stable, which prevented any major price drops. However, without strong demand, upward movement was limited. In September 2025, prices softened further by around 1.0% compared to August. Overall, the Indian market maintained a subdued but stable tone throughout Q3.

Mexico: Gradual Increase with Minor September Dip

In Mexico, Polyoxymethylene import prices at CIF Manzanillo from the USA showed a positive trend. Prices increased by an average of 2.9% in Q3 2025 compared to the previous quarter.

The rise was supported by steady regional demand and consistent procurement activity. Feedstock costs remained stable, and supply levels were adequate. Competitive offers ensured smooth trade flows without extreme volatility.

In September 2025, prices declined slightly by 0.4% compared to August. This small drop was linked to moderated demand and sufficient inventories. Despite this minor monthly adjustment, the overall quarterly trend remained positive and stable.

USA: Firm and Balanced Market

The Polyoxymethylene price trend in the United States also showed strength during Q3 2025. Export prices from FOB Houston increased by around 3.0% compared to Q2 2025.

Steady regional demand and consistent procurement activity supported this increase. Feedstock costs for formaldehyde and related intermediates remained stable, helping producers maintain firm price levels.

In September 2025, prices experienced a small 0.4% decline compared to August due to slightly moderated demand and sufficient supplier inventories. However, the overall tone of the market remained firm and balanced throughout the quarter.

China: Positive Growth with Late Adjustment

In China, Polyoxymethylene import prices at CIF Shanghai from South Korea rose by approximately 3.44% in Q3 2025. The Polyoxymethylene price trend was driven by firm regional demand and stable supply conditions.

Procurement activity remained consistent, and feedstock prices were stable. Competitive offers ensured smooth transactions and prevented sharp market swings.

However, in September 2025, prices declined by about 2.0% compared to August due to moderate demand and adequate inventories. Despite this monthly correction, the overall quarterly movement remained positive.

Key Factors Supporting POM Prices

Several common factors supported POM prices globally in Q3 2025:

• Balanced supply-demand fundamentals

• Stable feedstock costs

• Consistent procurement activity

• Adequate but not excessive inventory levels

• Stable industrial production in major regions

Unlike markets that experience oversupply or sudden demand drops, the Polyoxymethylene price trend in Q3 reflected a steady and healthy environment in most regions.

In simple terms, Q3 2025 was a stable and positive quarter for the global Polyoxymethylene market. Most regions saw gradual price increases ranging from 2% to 3.5%. Countries like South Korea, the USA, China, Mexico, Thailand, and Vietnam experienced steady growth supported by balanced market conditions. India was the only key market that showed a mild decline due to reduced domestic demand and adequate inventories.

Overall, the Polyoxymethylene price trend demonstrated how stable feedstock costs, steady procurement, and balanced supply-demand fundamentals can support gradual price growth. While minor monthly fluctuations occurred in September across several regions, the broader quarterly picture remained firm. If these stable fundamentals continue, POM prices are likely to maintain steady movement in the coming months.
