How this is calculated

FORMULA
S1 = LyondellBasell shipment value / total shipment value = 7.2%
CR3 = LyondellBasell + Dow (commodity portion) + ExxonMobil Chemical = 16.6%
HHI = Σ(share²) = 98 (Unconcentrated (HHI < 1,500))
DENOMINATOR
Shipment Value — $320B (US)
US commodity chemical manufacturing — basic petrochemicals (ethylene/propylene/aromatics), commodity polymers (PE/PP/PVC/PS), basic inorganics (chlor-alkali/soda ash/sulfuric acid), and manufactured fertilizers. Excludes industrial gases (own market) and specialty chemicals (own market).

METHODOLOGY NOTE
LyondellBasell US polymer + Olefins/Polyolefins-Americas + I&D-Americas FY24 ~$23B, Dow commodity-allocated US shipments ~$18B (P&SP + II&I US portion of $43B global, with commodity weighting ~70%), ExxonMobil Chemical US Chemical Products segment ~$12B FY24. Combined US denominator ~$320B per ACC + segment 10-K reconciliation. Many ethylene crackers are JV/captive (Chevron Phillips = CVX-Phillips66 JV; Equistar; INEOS), making merchant share more fragmented than top-3 capacity suggests. See sub-segments for the granular consolidation story — particularly fertilizers (Nutrien-led oligopoly, CR3 77%).

Hidden concentration inside Commodity Chemicals

The parent CR3 understates aggregation. Within these sub-segments — Fertilizers (Nitrogen + Phosphate + Potash) runs CR3 of 77%. Sub-segments below cover $296B of the market and are informational; they do not feed the 62-market dataset summary figures.

Basic petrochemical building blocks — ethylene, propylene, butadiene, benzene, aromatics. Chevron Phillips (CVX-P66 JV) is p4 ~$5B. Many ethylene crackers are JV/captive structures, so merchant share is more fragmented than capacity rankings suggest.

Bulk commodity plastics — polyethylene, polypropylene, PVC, polystyrene. Westlake, Shintech, and Formosa add meaningful PVC capacity; Chevron Phillips is large in HDPE. More concentrated than petrochemical building blocks because polymer-grade chains favor scale.

Chlor-alkali (chlorine, caustic soda) + soda ash + sulfuric acid. Genuinely concentrated within the US — chlor-alkali is a 3-firm oligopoly. Soda ash is a true Wyoming trona oligopoly: Solvay + Genesis + WE Soda hold ~85% combined.

Highest concentration sub-segment in commodity chemicals. Nutrien (post Agrium-PotashCorp 2018 merger) commands nearly 40% of US manufactured fertilizer shipments. True oligopoly — Koch Fertilizer (private) is p4 ~$3B. The 'commodity' label hides a tight cartel-adjacent structure protected by mining + capital intensity.

of revenue

LyondellBasell FY2024: $40.3B revenue / ~19,000 employees ≈ $2.12M per employee — exceptionally high due to capital-intensive cracker assets with thin labor headcount. SG&A ~6% of revenue. AI compressibility low; commodity chemicals are physics-bound, not knowledge-work-bound.
