Strategic Responses

M&A (Vietnam, Indonesia, Philippines), recycling partnerships with FMCGs, and capacity/price discipline aim to protect share and margins.

Market specifics and competitive dynamics by segment:

Segment Dynamics & Key Competitors

Notable competitive facts and metrics through 2024–2025:

• In Thailand cement, SCG and Siam City Cement share oscillated within a few percentage points in 2023–2024 due to price discipline and energy-cost pass-through; national cement demand grew low-single digits.
• SCGC margins were pressured in 2023 as Asian naphtha crackers lagged US ethane peers; by 2024–2025 recovery narrowed gaps but US/ME exports continued to exert price pressure on ASEAN producers.
• SCGP expanded via acquisitions across Vietnam, Indonesia, and the Philippines to counter Oji and local groups; containerboard demand softened in 2022–2024 causing temporary share shifts and capacity curtailments.
• Feedstock and scale remain decisive: PTTGC and regional integrated producers maintain advantages in aromatics/olefins; global polymer majors compete on specialty grades and reliability.
• Recycling and circularity partnerships with FMCGs are raising qualification barriers in packaging, shifting competition toward integrated players with recycled-fiber supply chains.
• Cross-border pricing influence from Semen Indonesia and Cemex Philippines affects Thai export/import flows; Chinese exports add downside pressure on regional cement prices.
