rCB Has No Public Price: A Data Point That Doesn't Exist, and the Reference System Around It
In one line: Virgin carbon black is up more than 55% year-to-date, with coal tar accounting for 65–80% of cost — yet recovered carbon black (rCB) still has no independent public price series. That gap is not our oversight; it is the state of the industry.
1. Virgin carbon black: one clear upward line
| Period | Price | Change |
|---|---|---|
| March 2026 | CNY 7,671/t (previous 7,057) | +8.7% month-on-month (official monthly basis) |
| Aug–Sep 2026 | Industry statement: "some grades have broken CNY 10,000 and are approaching 12,000/t" | Cumulative gain of roughly +55% or more against the March anchor |

2. The rise is on the cost side: coal tar
- Coal tar accounts for 65–80% of carbon black production cost
- Year-to-date: coking coal up about 77%, coke up about 36%
- Some coal tar auction prices are approaching the December 2022 historic high

What this means: the increase is cost-push, not demand-pull. The distinction matters — cost-push increases differ in downstream acceptance and in how long they hold.
3. The import–export "scissors"
| Metric | Value |
|---|---|
| Monthly export average price (USD/t) | 995.78 → 1,021.76 → 1,052.32 → 1,157.41 (Jan–Apr 2026, four consecutive rises; April turned positive YoY at +3.01%) |
| Import average price | USD 2,186.88/t (+33.12% YoY) |
| Import volume | 88,001 t (−40.64% YoY) |

How to read it: export prices rising, import prices rising faster, and import volume halved. In the same price cycle, the value proposition of overseas product entering China is falling quickly — which usually signals room for domestic substitution.
4. But rCB's price cannot be looked up
This is the single most important thing to state:
There is no independent public price series for rCB in official channels or announcements.
We verified this: it is not that we failed to find it — the data does not exist:
- Virgin carbon black has official monthly reports and branch-level trade data — rCB has no corresponding official series
- Why: rCB currently trades mainly on bilateral long-term contracts, with price terms not publicly disclosed
So we cannot give you an "rCB price". Anything presented as one would be an estimate, not a quote.
5. The question therefore becomes: how to build a traceable reference system
When a market lacks a benchmark, there are two paths: invent a number, or build a verifiable method. We chose the latter.
Our reference range (ABP) comes from an explicit formula:
ABP(t) = AF(t) × VF(t) × 1000
| Factor | Meaning | Verifiability |
|---|---|---|
| AF (anchor factor) | The relative base-period ratio of the virgin carbon black anchor price | Strictly traceable — the anchor series is official monthly data |
| VF (value factor) | A synthesised driver-factor value for rCB's relative value | ⚠️ Not price-calibrated — an expert judgement range |
Base and layering: - Base period 2025-01, base value 1000 - Classification per the ASTM D8632 two-parameter matrix (R value + toluene transmittance grade + inorganic content grade) - Layers: P1 refined / P2 standard / P3 industrial (each with a different ρ)
The primary anchor: China's carbon black export average price (HS 28030000, all grades) — from the official monthly import/export tables of the Carbon Black and White Carbon Black Branch, China Rubber Industry Association, traceable month by month.
6. What we explicitly do not do (this matters more than the numbers)
An index without stated boundaries is more dangerous than no index. So these limits are deliberately written into the method:
| Limitation | Statement |
|---|---|
| Not a transaction price | This index is a reference range; rCB trades mainly on bilateral long-term contracts with undisclosed price terms |
| Anchor scope is limited | The primary anchor is an all-grade export average, applicable only to standard grade and below, not usable for anchoring premium/specialty tiers |
| Single-grade series missing | No official series exists for grade N550 alone; any absolute-price derivation involving it is separately flagged |
| Regional coefficients uncalibrated | Regional coefficients are placeholder values under calibration; regions that fail calibration do not publish figures (e.g. NA and SEA do not publish in phase one) |
| VF uncalibrated | VF is an expert judgement range, not calibrated against historical price data; it applies prospectively only from July 2026 and is not backfilled |
| Historical period differs in nature | The historical period (2024-01 to 2025-12) is a pure anchor trend, with VF marked not_assessed |
| Classification ≠ interchangeability | ASTM D8632 is a classification standard, not an interchange specification — products within the same layer still differ in quality |
In one line: we provide a shape-credible, traceable relative trend, while the plausibility of absolute prices still requires calibration. What can be published and what is withheld — and why — is flagged entry by entry in the data.
7. What this means for the rCB industry
1. Cost-push increases widen rCB's price advantage — but only if it can be measured. Rising virgin carbon black prices should improve rCB's substitution economics. But if neither side can produce a comparable reference, negotiation falls back on intuition.
2. The absence of a public price is itself a maturity indicator. A category without independent public pricing usually means: opaque transactions, insufficient standardisation, long-contract dominated. All three describe rCB today.
3. Standardisation is the precondition for pricing. That is why we built the ASTM D8632 classification matrix into the method — you can only price in tiers once you can define tiers.
4. For buyers and users: absent a public price, establishing an internal reference line from "anchor benchmark + layer coefficient" is better grounded than picking a number — at minimum it can be traced and challenged.
8. Scope and disclaimer
The rCB reference range (ABP) is research reference material — not a transaction price, not a quote, and not a basis for trading. The primary anchor is the virgin carbon black export average price (official monthly industry data), applicable only to standard grade and below. Virgin carbon black price data comes from industry associations (China Coking Industry Association / China Rubber Industry Association) — an industry-body basis, not a government release.
