# Purified terephthalic acid: Cycles

A business that lives on a thin processing fee

Source page: https://www.materialinsights.org/chemicals/pta/cycles/

What this tab covers How its prices and margins move: past booms and busts with price levels, the spread or margin that the industry watches, the drivers of the cycle and the metrics to track.

PTA is a conversion business: its price is PX plus a processing fee. The fee is the cycle. Chinese overbuilding since 2019 has kept fees near or below cash cost for much of 2023-2025, with Chinese margins about $40/t in late 2024 (Argus) and fees around CNY200/t in mid-2025 (Tiger Brokers). The floor is set by run cuts and announced production cuts among Chinese producers; the ceiling by polyester demand peaks and plant outages. Absolute prices follow crude through PX.
 The spread to watch **PTA processing margin (PTA minus 0.655 x PX)**

Chinese processing fee about CNY200/t in July-October 2025 (Tiger Brokers). Chinese offers in January 2026 were PX plus $45-55/t; non-China plants need PX plus at least $100/t (S&P Global).

#### Booms and busts

1. 2021-2023

India imported heavily from China, peaking at about 960,000 t in 2022 (derived from Tiger Brokers). From mid-2023 India's BIS quality-control order stalled Chinese imports (S&P Global, Jun 2023).

2. Late 2024

New Chinese PTA met weak polyester demand. Margins fell below breakeven and producers announced cuts.

China PTA margins about $40/t; PTA fell 3.4% in early November 2024 (Argus)

3. 2025-January 2026

Processing fees stayed around CNY200/t, implying losses (Tiger Brokers). India revoked the QCO in late 2025 and Chinese exports to India jumped.

PTA $649/t FOB China and $687/t CFR India on 21 Jan 2026 (Platts via S&P Global)

#### What drives the cycle

- **Chinese capacity additions.** New 2.5-3 Mt/yr trains keep the industry long; four more are planned for 2027-2028.
- **Polyester demand.** Textiles and bottles; Chinese PTA ran at 70-71% in October 2026 as polyester demand lagged (Procurement Resource).
- **India's trade policy.** QCOs and anti-dumping decisions switch Chinese exports to India on or off.
- **PX price.** About 85-90% of cost; crude shocks pass through.

#### Metrics to track

| Metric | Why it matters | Where to track it |
|---|---|---|
| **ZCE PTA futures** | Most liquid polyester-chain price | Zhengzhou Commodity Exchange |
| **PTA processing fee** | Margin signal | CCF, Mysteel, Tiger Brokers |
| **China PTA exports by destination** | India and Turkey demand | GACC |
