Chlorine Market Analysis: Price Trend, Trade Data and PVC Demand

Data source: UN Comtrade public trade statistics (https://comtradeapi.un.org/public/v1/preview/C/M/HS?reporterCode=156,842,699,410,276,528,356,360,764,458,724,40,56,251,380,616,826,124,76,484,792,682,784,704,490,702,643,36,710,818,364,203,348,300,620,372,208,246,752,578,320,508&period=202607&cmdCode=280110&partnerCode=0&flowCode=X&includeDesc=true) | Last updated: 2026-10-30

Price Trajectory, latest 12 months (2025-08 to 2026-07)

The monthly customs export unit value for HS 280110 moved from USD 724.30/ton in 2025-08 to USD 448.68/ton in 2026-07 (-38.1% across the window). The window high was USD 742.30/ton in 2025-11 and the low USD 398.28/ton in 2026-05. Three-month averages put the latest quarter -0.9% against the previous one, which is classified here as neutral.

The same panel reported USD 156.8 million of export value on 301,235 tonnes over the twelve months, an average of 25,103 tonnes a month. Values are customs returns for the stated HS heading, so they capture the traded mix of that heading rather than a single quoted grade.

The EU side of the same market gives a volume check rather than a price: Eurostat Comext records EU27 imports of HS 280110 from outside the EU at 48 tonnes in 2026-08 and 422 tonnes over the twelve months to 2026-08. Monthly consignments at that size are too small for a unit value to mean anything, so no EU import price is published here.

2026-08 is not used yet: 8 of the listed reporters had filed both value and net weight for this heading when this page was rebuilt, against the 14 that make up the locked panel used here, and 2026-09 had no filings at all. Mixing a partly-filed month into a fixed panel would move the unit value through composition alone, so the window is held at 2026-07 until the panel for 2026-08 is complete.

HS 280110 carries chlorine only, so the series is product-level; it does not separate liquid chlorine from chlorine shipped as a liquefied gas under pressure, nor does it identify purity grades.

Supply-side factors

• Fixed reporting panel of 14 economies: AUS (36), CAN (124), CZE (203), DNK (208), DEU (276), GTM (320), HUN (348), MYS (458), MEX (484), NLD (528), PRT (620), IND (699), SWE (752), USA (842). The panel is held constant in every month of the window so month-to-month movement is not a composition effect.
• Monthly unit value range over the window: USD 398.28 to USD 742.30/ton.
• Latest month, 2026-07: USD 448.68/ton, +9.3% against the previous month, on 30,185 tonnes.

Demand-side factors

• Chlorine demand is dominated by ethylene dichloride and vinyl chloride for PVC, with isocyanate (TDI/MDI) production, water and waste-water treatment, chlorinated solvents and inorganic chlorides taking the balance. Because chlorine is expensive to store and ship, traded volumes are a residual of local chlor-alkali balances rather than a global clearing price.

Basis: these are customs unit values for the stated HS heading, not quoted spot, contract or assessed prices, and no paid price assessment is used or redistributed on this page. Every figure can be re-checked at the API links listed at the end of this page.
