China Silicone Prices in March 2021: Historical Market Note
Direct Answer: Did Silicone Prices Rise After the 2021 Chinese New Year?
This page is a historical market note published on 5 March 2021—not a current quotation or price forecast. The original note recorded seller quotations for China DMC moving from about RMB 21,000/tonne in early February to nearly RMB 25,000/tonne in early March, a reported increase of roughly 19%. These quotations were not drawn from an official statistical series and must not be used as today’s purchasing price.
Historical claims and sources reviewed: 13 August 2026.
Reported Dow Silicone Price Increase (2021)
The original 5 March 2021 article reported that Dow planned a 5%–20% adjustment for certain high-performance construction silicone products from 20 March. During this 2026 audit, a matching Dow announcement could not be independently confirmed in the public archive reviewed. Treat this as an unverified historical report, not proof of a current Dow price or a prediction for China’s silicone market.
WACKER’s official release dated 10 March 2021 announced a global increase of 10%–20% for its entire silicone range, effective for material shipped from April as contracts allowed. The release cited higher strategic raw-material costs, support and packaging materials, and pandemic-related service measures. This corrects the earlier wording that described a single 20% increase effective 1 March.
Energy prices were also rising at the time: the U.S. EIA’s March 2021 outlook reported that front-month Brent increased by USD 10.39 per barrel between 1 February and 4 March 2021. That is useful historical context, but it does not prove that crude oil or any government stimulus directly caused every silicone price adjustment.
Reported China DMC Quotes in February–March 2021
The original market note recorded indicative China DMC seller quotations of approximately RMB 21,000/tonne in early February 2021 and close to RMB 25,000/tonne in early March—a reported increase of RMB 4,000/tonne, or about 19%. It also reported limited or suspended quotations from some monomer producers. Because no official DMC price series or named quotation panel was supplied, these figures should be read as contemporaneous market observations rather than independently verified benchmarks.
Evidence-Based Context for the 2021 Price Movement
How to Use This Historical Price Note
- Do not use the 2021 quotations as a current buying price or supplier offer.
- For current sourcing, request dated quotations with product grade, active content, packaging, Incoterm, currency, validity and minimum order quantity.
- Separate verified company announcements from market commentary and macroeconomic interpretation.
- Track upstream inputs and logistics as risk indicators, but validate the effect on the exact silicone intermediate or finished defoamer.
No current-price conclusion is made on this page. Historical price direction does not establish the next market move.
Evidence Sources & Historical Method
- WACKER press release, 10 March 2021 — 10%–20% increase for its global silicones range, effective for April shipments as contracts allowed.
- U.S. EIA Short-Term Energy Outlook, March 2021 — contemporaneous crude-oil price and supply context.
- Dow first-quarter 2021 results — reports local price gains for siloxanes and supply constraints, but does not independently verify every claim in the original article.
Method: Company announcements and official historical energy data are distinguished from unnamed market quotations. This archive does not provide a current silicone or defoamer price.
