ARCANE's chain index records cracker configuration and catalyst supply as the narrowest named step. This reference record exposes the known constraint and substitution window without assuming unnamed tiers, nodes, or company exposures.
Cracker configuration and catalyst supply is the chain's named pacing step
The current reference map identifies feedstock spread, power as the constraint readers should test first. The record does not claim a supplier count or a live output level; it establishes where a disruption must be checked before a sector-level conclusion is made.
The recorded substitution window is 12–24 m. That is the decision-relevant interval: an alternative that exists outside it does not relieve the operating cycle that needs it.
Is feedstock spread, power becoming the pacing step for this chain, rather than a symptom reported downstream?
- Observe
- Start at the named step: Cracker configuration and catalyst supply. Compare a source record for that step with the downstream delivery or recognition it is meant to constrain.
- Boundary
- This is a 5 recorded tiers reference chain with a recorded substitution window of 12–24 m. It does not establish issuer exposure until a named record supports it.
- Breaks the read
- A custody-backed record showing that an alternative clears inside 12–24 m, or that downstream delivery no longer moves with feedstock spread, power, would weaken this chain read.
Hengli obeys U.S. sanctions even as Beijing orders firms to defy them
China’s Hengli Petrochemical stopped sanctioned crude purchases despite government opposition, showing U.S. penalties can override official defiance inside major Chinese companies.
