Chlorosulphonated Polyethylene Rubber Prices: Chart, Trends, Market Analysis and Forecast Q3 2026

According to ChemAnalyst,  The global Chlorosulphonated Polyethylene (CSM) Rubber Prices experienced a broadly upward trend during the third quarter of 2026, supported by increasing feedstock expenses, higher international logistics costs, and regional differences in import availability. Prices strengthened across APAC, Europe, and North America, although purchasing patterns and supply-side developments varied between markets. Rising Low-Density Polyethylene (LDPE) and chlorine costs influenced production economics in Asia, while elevated freight expenses and longer shipping lead times contributed to higher landed costs in North America.

During Q3 2026, the average Chlorosulphonated Polyethylene price in APAC reached USD 4,075.00/MT FOB Qingdao, China, representing a 1.03% quarter-over-quarter increase. Europe recorded an average price of USD 4,253.33/MT CFR Hamburg, Germany, reflecting a 2.22% increase. North America experienced the strongest appreciation, with prices averaging USD 4,419.33/MT CFR Houston, USA, marking a 4.66% quarter-over-quarter rise.

Despite the overall positive quarterly performance, September witnessed some moderation in Asian and European markets as export inquiries weakened, buyers adopted cautious procurement strategies, and lower international transportation expenses improved import availability. In contrast, North American prices maintained upward momentum due to higher freight charges, increased feedstock costs, and extended procurement lead times.

Chlorosulphonated Polyethylene Rubber Prices in APAC

The APAC Chlorosulphonated Polyethylene Rubber Price Index increased by 1.03% quarter-over-quarter during Q3 2026, with the average price reaching approximately USD 4,075.00/MT FOB Qingdao, China. The upward movement was primarily associated with higher feedstock costs, particularly LDPE and chlorine, which increased production expenses and encouraged manufacturers to maintain firmer export quotations.

During July and August, the Chinese market experienced relatively stronger pricing momentum as LDPE adhesive-grade costs increased and producers maintained disciplined operating rates. Higher raw material expenses reduced manufacturing margins, prompting suppliers to protect profitability through more cautious pricing strategies. Although production remained broadly steady, seasonal electricity restrictions and a maintenance shutdown at Ningxia Boyuan limited the availability of some spot material.

Export demand also contributed to the positive market sentiment during the first two months of the quarter. Buyers from Vietnam and India actively explored procurement opportunities and secured fourth-quarter requirements, providing additional support to Chinese exporters. This demand helped producers maintain relatively stable selling positions despite the availability of domestic inventory.

However, the market experienced a softer tone in September. Overseas inquiries from Vietnam and India declined, reducing export bookings and weakening suppliers’ negotiating leverage. At the same time, stable chlorine and HDPE availability prevented further significant increases in manufacturing costs. Sufficient warehouse inventories and scheduled shipments also reduced immediate restocking requirements among buyers.

Consequently, some traders offered modest discounts to attract customers and maintain sales volumes. Nevertheless, inventories remained broadly within seasonal norms, preventing substantial oversupply and limiting the extent of price reductions.

Why Did Chlorosulphonated Polyethylene Rubber Prices Change in September 2026 in APAC?

Several factors influenced the September price movement in the Asian market:

• Weaker export inquiries: Reduced purchasing interest from Vietnam and India lowered export bookings and weakened sellers’ bargaining power.
• Stable feedstock availability: Consistent chlorine and HDPE availability helped contain production expenses and reduced upward pricing pressure.
• Sufficient inventories: Normal warehouse stock levels and scheduled shipments reduced buyers’ immediate procurement requirements.
• Competitive selling strategies: Traders offered modest discounts to maintain sales volumes amid slower international demand.

Chlorosulphonated Polyethylene Rubber Prices in India

The Indian Chlorosulphonated Polyethylene Rubber market remained influenced by import availability, overseas supplier quotations, and international freight movements during Q3 2026. Prompt import cargoes remained relatively limited, reducing short-term material availability and supporting suppliers’ ability to maintain elevated offers.

Although lower shipping costs provided some relief to Indian importers, these savings were insufficient to fully offset higher supplier quotations. Consequently, buyers continued to face relatively firm landed procurement costs.

Importers generally adopted cautious purchasing strategies, balancing immediate consumption requirements against expectations of improved availability and more competitive overseas offers. The market outlook remained dependent on Chinese export pricing, shipping schedules, and the availability of prompt cargoes.

Chlorosulphonated Polyethylene Rubber Prices in Europe

The European Chlorosulphonated Polyethylene Rubber Price Index increased by approximately 2.22% quarter-over-quarter during Q3 2026. Germany recorded an average price of around USD 4,253.33/MT CFR Hamburg, reflecting stronger supplier quotations during the earlier part of the quarter.

The quarterly increase occurred despite a softer market environment in September, when lower international shipping costs, cautious downstream purchasing, and competitive import offers moderated pricing momentum.

During the first half of the quarter, European buyers encountered relatively firm import quotations as international feedstock and transportation costs influenced supplier pricing strategies. However, the market gradually shifted toward a more balanced position as overseas producers maintained regular output and warehouse availability remained adequate.

Chinese and US manufacturers continued supplying the European market, preventing substantial shortages and supporting relatively stable import flows. German automotive and roofing manufacturers remained cautious about fresh procurement, relying partly on existing inventories and limiting additional spot purchases during September.

Currency movements also influenced import economics. The depreciation of the euro against the US dollar increased the local-currency cost of imported material, partially offsetting the benefits of lower international shipping expenses. This created mixed pricing signals for European distributors and end users.

Another important development was the approval of an additional South Korean grade, which broadened sourcing opportunities for European buyers. Increased supplier competition placed additional pressure on import quotations and encouraged more competitive offers into Hamburg.

Lower international transportation costs further reduced landed import expenses, allowing suppliers to compete more aggressively. However, moderate downstream consumption and existing inventories restricted the potential for stronger price increases.

Why Did Chlorosulphonated Polyethylene Rubber Prices Change in September 2026 in Europe?

The September market movement in Germany was influenced by several interconnected factors:

• Moderate downstream consumption: Automotive and roofing manufacturers maintained cautious procurement strategies, limiting fresh spot demand.
• Lower shipping costs: Reduced international freight expenses lowered landed import costs and encouraged more competitive supplier offers.
• Currency depreciation: A weaker euro increased local-currency import expenses, partially offsetting freight-related savings.
• Additional supplier competition: Approval of another South Korean grade expanded sourcing options and increased competitive pressure.
• Stable overseas production: Regular production in China and the United States supported consistent shipments and prevented significant supply shortages.

Overall, the European market maintained a positive quarterly price performance, although September developments indicated limited scope for further substantial increases.

Chlorosulphonated Polyethylene Rubber Prices in North America

North America recorded the strongest quarterly increase in Chlorosulphonated Polyethylene Rubber prices during Q3 2026. The US Chlorosulphonated Polyethylene Rubber Price Index increased by 4.66% quarter-over-quarter, with the average price reaching approximately USD 4,419.33/MT CFR Houston.

The upward movement was primarily driven by higher landed import costs, increasing international shipping expenses, and rising LDPE feedstock prices. Unlike the Asian and European markets, where September witnessed some moderation, North American prices continued to experience upward pressure due to logistics-related cost increases.

In September, Chlorosulphonated Polyethylene Rubber prices increased by approximately 0.52% month-over-month. Higher international freight expenses contributed to this movement by increasing the overall cost of imported material delivered to the US Gulf Coast.

Feedstock expenses also played an important role. Low-Density Polyethylene costs increased by 1.34% during September, tightening the margin flexibility of overseas producers. Manufacturers consequently had less room to reduce export quotations, keeping landed prices relatively firm for American importers.

Chinese and Japanese exporters maintained regular production levels, ensuring that export availability remained broadly stable. However, increased international shipping expenses and extended delivery lead times limited the flexibility of US buyers seeking prompt replacement material.

The domestic demand environment remained relatively stable. Roofing, wire-and-cable, and automotive applications continued supporting baseline consumption, preventing a substantial decline in purchasing requirements. Nevertheless, Gulf Coast distributors maintained lean inventories and followed needs-based procurement strategies to manage working capital and avoid excessive stock accumulation.

The combination of steady consumption, higher freight expenses, and limited prompt availability supported the overall upward market direction during the quarter.

Why Did Chlorosulphonated Polyethylene Rubber Prices Change in September 2026 in North America?

Several market developments contributed to the September price increase in the United States:

• Higher international freight expenses: Increased shipping costs raised the landed price of imported Chlorosulphonated Polyethylene Rubber.
• Rising LDPE costs: A 1.34% increase in LDPE feedstock expenses tightened overseas manufacturers’ margin flexibility.
• Extended delivery lead times: Longer procurement schedules limited buyers’ ability to secure prompt replacement cargoes.
• Lean distributor inventories: Limited stock availability increased the importance of timely imports and supported supplier pricing.
• Stable downstream consumption: Roofing, automotive, and wire-and-cable applications continued providing consistent demand support.

Although regular production in China and Japan prevented severe supply tightness, the combination of higher logistics expenses and feedstock costs maintained an upward pricing bias across the North American market.
