In Q3 2025, Glass Fibre Prices remained mostly stable across global markets, with only small increases or decreases depending on the region. Compared to other chemical and material markets, glass fibre showed a relatively balanced performance. The main reasons behind price changes were freight costs, currency movements, and small shifts in local demand. Raw material costs, such as silica and other chemicals used in production, stayed largely steady during the quarter.

Glass fibre is widely used in construction, automotive parts, wind energy blades, infrastructure materials, and electronics. Because it plays an important role in many industries, price stability often reflects overall industrial health. In Q3 2025, demand from construction and renewable energy projects helped maintain a supportive market environment.

China: Slight Softness Due to Export Competition

In China, export prices from Shanghai showed a small decline in September 2025. Prices slipped by about 0.30%, averaging between USD 690 and 730 per metric ton for E-Glass Fiber Chopped Strands.

The slight drop in Glass Fibre Prices was mainly linked to softer overseas demand and stronger competition among Asian exporters. New production capacity in China increased domestic inventories, which put mild pressure on exporters. To maintain sales volumes, some suppliers adjusted prices slightly.

However, raw material costs remained stable, and logistics operations ran smoothly. Because of this, price adjustments were limited. The overall Chinese market still appeared balanced, and expectations for the next quarter remained steady.

South Korea: Stable Market Conditions

In South Korea, import prices at Busan remained steady throughout September 2025. The quarter showed quiet price movement, with no major increases or declines.

The stability in Glass Fibre Prices was supported by consistent demand from construction and automotive sectors. Buyers managed their inventory carefully, purchasing materials according to project timelines rather than building excess stock.

Feedstock costs did not change significantly, and regional trade flows remained smooth. These factors helped keep the market balanced. South Korea reflected how stable demand and disciplined procurement can support price stability.

Brazil: Freight Costs Push Prices Higher

Brazil saw a noticeable increase in Glass Fibre Prices during September 2025. Import prices at Santos rose by around 3.5%.

The main reason behind this increase was higher global freight rates, which raised landed costs. Brazil depends heavily on imports, so changes in shipping costs directly impact local pricing.

At the same time, domestic demand remained strong, especially from infrastructure projects and wind energy installations. These sectors require large amounts of glass fibre for reinforced materials and turbine blades. While raw material costs stayed stable, higher shipping expenses created upward pressure.

If freight rates continue to remain high, Brazil may see continued price strength in the coming months.

India: Stable but Slightly Firm Tone

India showed two different but related trends—domestic and import markets.

In the domestic market in Delhi, Glass Fibre Prices remained stable in September 2025, averaging between INR 79,000 and 86,000 per metric ton. Demand from construction, composites, and infrastructure sectors stayed healthy.

There was a slight upward tone due to local logistics costs and higher operating expenses. However, adequate supply and controlled inventory levels prevented large price changes. Producers followed a disciplined pricing strategy.

On the import side, prices at Nhava Sheva increased by around 4%. This rise was mainly driven by higher global freight rates and depreciation of the Indian rupee against the U.S. dollar. When currency weakens, imported materials become more expensive.

Although raw material prices abroad were steady, shipping and exchange rate movements were the key drivers. If freight and currency conditions improve, prices may stabilize again.

In the Mumbai domestic market, prices at Mumbai edged up about 1.2% in September 2025. Strong demand from wind energy, transportation, and construction sectors supported this small increase. Overall, India showed a cautiously positive market outlook.

United States: Freight Relief Lowers Prices

In the United States, import prices at Houston declined by about 3.75% in September 2025.

The main reason was lower freight costs and improved shipping conditions. Ports operated efficiently, and supply availability remained comfortable. Healthy demand from construction, automotive, and aerospace sectors supported active procurement.

Even though demand remained strong, reduced logistics expenses helped bring Glass Fibre Prices slightly lower. This shows how freight costs can influence pricing even when industrial activity remains steady.

If shipping costs stay moderate, the U.S. market may continue to see stable or slightly softer pricing.

Japan: Freight Hikes Drive Price Spike

Japan experienced one of the sharper price increases in September 2025. Import prices at Tokyo rose nearly 6%.

The primary driver was higher global shipping rates and logistical delays. Even though raw material costs stayed stable, freight escalation significantly increased landed costs.

Demand from automotive and electronics sectors remained resilient. Infrastructure development also supported consumption. Importers accepted higher prices to ensure steady supply and avoid project disruptions.

If freight volatility continues, Japan may face ongoing pricing pressure in the coming quarter.

Key Factors Influencing Glass Fibre Prices

Looking at global trends in Q3 2025, several common factors influenced Glass Fibre Prices:

1. Freight Rate Changes – Shipping costs played a major role, especially in Brazil, India, Japan, and the USA.

2. Currency Movements – Exchange rate changes affected import-heavy markets like India.

3. Stable Raw Material Costs – Silica and chemical inputs remained steady, preventing major cost-driven spikes.

4. Steady Demand from Construction and Wind Energy – Infrastructure and renewable energy projects provided market support.

5. Balanced Supply Levels – Production remained sufficient without major shortages.

Overall, the glass fibre market did not face strong supply disruptions or raw material shocks. Instead, logistics and currency factors shaped most regional price changes.

Market Outlook for Q4 2025

Moving into the next quarter, the outlook for Glass Fibre Prices appears generally stable. If freight rates normalize and currency fluctuations ease, markets may see fewer price adjustments.

Demand from construction, automotive, and renewable energy sectors is expected to remain supportive. Wind energy expansion in particular continues to create steady consumption of glass fibre materials.

However, markets will closely monitor shipping conditions and global trade flows. Any major disruption in logistics could quickly influence pricing again.

In simple terms, Q3 2025 showed that Glass Fibre Prices were steady overall, with only moderate regional changes. While some countries experienced small increases due to freight or currency issues, the global market stayed balanced. Stable raw material costs and consistent industrial demand helped prevent major volatility.
