Polyacrylate rubber (ACM) is a specialty elastomer, but in Q3 2026 its price rose sharply. In China, the price index jumped 19.13% from Q2, and the quarterly average reached about USD 6,000/MT FOB Shanghai. That is the third quarterly increase in a row and about 29% above Q1 2026.
The bigger change for buyers is the regional gap. In Q2, US buyers paid about USD 1,273/MT more than the Chinese FOB price. In Q3, the gap shrank to about USD 480/MT. The usual cost advantage of buying from China has mostly disappeared.

Why ACM prices matter
ACM is made from acrylic acid and acrylate esters, which are linked to propylene. It resists heat and oil, so it is the material of choice for:
- Automotive transmission and engine seals
- Gaskets and O-rings that handle hot oil
- Turbo and oil hoses
- Industrial seals for compressors and machinery
When an ACM seal fails, the cost to the customer is far higher than the cost of the rubber. Buyers therefore need reliable supply as much as a good price.
Q3 2026 at a glance
🇨🇳 China (FOB Shanghai): about USD 6,000/MT, +19.13% vs Q2
🇺🇸 United States (CFR): about USD 6,480/MT, compared with about USD 6,310/MT in Q2
🇮🇳 India: import costs rose because of a late-September freight spike and a weaker rupee
🇪🇺 Europe: prices depended on feedstock costs, Asian import supply and automotive demand
China: three quarters of increases
- Q1 2026: USD 4,643/MT (+5.13%)
- Q2 2026: USD 5,037/MT (+8.47%)
- Q3 2026: USD 6,000/MT (+19.13%)
Each quarter’s increase was larger than the one before.
What drove the Q3 increase
1. VOC rules cut output. When new VOC (volatile organic compound) rules took effect in July, producers reduced operating rates. Output fell by about 800 tonnes, which removed most of the spot supply.
2. Higher feedstock costs. Acrylic acid and acrylate esters rose with propylene, increasing production costs.
3. Logistics problems. During heat waves, trucking slowed down, and warehouses at East China ports ran unusually low. Sellers had no reason to discount.
4. Strong export demand. Enquiries from South Korea, India and Europe increased, with buyers asking for cargoes to be shipped early for immediate delivery.
5. Car production. China’s passenger vehicle output rose 6.9% year-on-year in July, supporting demand for high-temperature seals.
ChemAnalyst’s outlook points to modest further upward pressure in the near term, as feedstock costs stay firm and export supply remains limited.
India: higher import costs
Indian importers faced two additional costs:
- Freight: Container rates from Shanghai to JNPT rose sharply in late September, and containers were harder to find.
- Currency: The rupee weakened from July to September, increasing dollar-denominated customs duties and letter of credit requirements.
Indian ACM prices had already risen 9.0% in Q2. With Chinese prices up again and higher landed costs, Q3 was more expensive for Indian buyers on every count.
United States and Europe
In the US, ACM was about USD 6,480/MT CFR in Q3, compared with about USD 6,310/MT in Q2. Feedstock costs, the price of imports and demand from automotive seal makers set prices. In Europe, acrylate feedstock costs, Asian import supply and freight determined delivered prices, and the Q4 outlook depends on automotive output and restocking.
What this means for buyers
1. China is no longer much cheaper. A gap of USD 480/MT barely covers freight and duty for many buyers. Compare total delivered costs, not just FOB prices.
2. Regulation now drives supply. VOC rules cut supply in China within weeks. Further environmental measures could do the same again.
3. Rubber is a small part of the cost of a seal. ACM is a small share of the cost of a seal, but a shortage can stop a production line. Securing supply matters more than saving a few dollars per tonne.
4. Indian buyers need to manage freight and currency risk. Freight spikes and rupee moves can add more to landed costs than the FOB price change.
Questions procurement teams should be asking now
- Have our Q4 offers already reflected the 19% increase in China?
- With the US–China gap at USD 480/MT, is a US or Korean supplier now competitive with China?
- How much will freight and currency add to our landed cost next quarter?
- Are more VOC restrictions planned that could cut Chinese output again?
