Carbon black price surge, September 2026: what it means for masterbatch buyers
Carbon black prices in China rose sharply in September 2026, reaching record levels. For masterbatch buyers the number itself matters less than what it does to quoting over the next one to two quarters — so here is the data, the cause, and what we are doing about it.

What happened
| Indicator | Value | Period / source |
|---|---|---|
| Carbon black benchmark price (China) | CNY 12,778.57/t | 16 Sep 2026, SunSirs (生意社) |
| Change since start of September | +39.77% | from CNY 9,142.8/t on 1 Sep |
| Shandong N330 market price | about CNY 12,000/t, +31.87% in one week | 15 Sep 2026 |
| Change since the start of 2026 | +87.64% — an all-time high | N220, reported 16 Sep 2026 |
| Coal tar feedstock (65–80% of carbon black cost) | CNY 4,600 → 6,720/t, +46% | early Sep → 15 Sep 2026 |
| Industry operating rate | 66.44%; major producers cut 30–40% | September 2026 |
Why it happened — and why it is not a seller's markup
The driver is upstream, not demand. Coking plants under sustained losses cut operating rates, which reduced coal tar availability; coal tar is the dominant input cost in the oil-furnace process, so its price ran up and pulled carbon black with it. The China Rubber Industry Association characterised this as a cost-driven, supply-contraction adjustment rather than demand overheating — in fact tyre producers are resisting the increases and running at around 65% utilisation, so volumes are weak.
One detail is worth pausing on: the industry's total profit in the first half of 2026 was negative CNY 115 million, and September is estimated to have been worse. In other words, the price rise has not made carbon black producers profitable — it has partly recovered input cost. That is a materially different situation from a speculative spike, and it changes how you should read a masterbatch price increase.
What it means if you buy black masterbatch
- Quotes will move, after a lag. How long depends on your supplier's raw-material inventory and the proportion of long-term contracts in their book. Suppliers running high contract cover will hold prices longer, then move.
- Higher carbon loading means more direct exposure. A 40–50% carbon grade carries roughly twice the carbon cost per kilogram of a 20% grade. If you are buying concentrates, expect proportionally larger movements.
- The right question is not "why did you raise the price" but "what is it indexed to". A defensible answer names the benchmark and states how often the price is revised. A price that mysteriously never moves across a quarter is not stability — it was never priced to the material.
- Filler and recycled carrier become more attractive — and must be disclosed. When carbon gets expensive, the incentive to substitute rises. Ask for the ash figure, which separates genuine carbon loading from carbon plus mineral filler.
Our position
We quote against the prevailing carbon black market and state a validity period on every quotation, so a quote is a dated document rather than an open-ended promise. If you need a firm figure for a longer horizon, tell us and we will structure it — but we will tell you what we have assumed rather than absorb an unknown and adjust later.
