National Industrial Cracking C5 Weekly Output Statistics Table

| Data | Previous Period | Current Period | Weekly Output |
| --- | --- | --- | --- |
| Cracking C5 Output (10,000 tons) | 7.45 | 7.44 | -0.1 |
| Data Source: chempricehub.com | | | |

This week, the output of industrial cracking C5 decreased slightly compared to last week, with a negligible change of 0.15%.

Individual enterprises saw small fluctuations in output this week, mainly within the normal range due to changes in feedstock charging. Overall output fluctuation was small. The ethylene unit of Sinopec-SK (Wuhan) Company started maintenance on June 4, and Hainan Refining & Chemical is expected to begin maintenance on June 6. Next week, cracking C5 output is expected to decline by approximately 3.6% compared to this week. Additionally, more enterprises are scheduled to enter maintenance periods at the end of the month.

Based on the maintenance schedules, the total cracking C5 output in June is forecast to be 306,700 tons. In July, as some enterprises complete their maintenance, output is expected to increase slightly compared to June. At the same time, enterprises that previously halted sales may resume sales.

Currently, the anticipated reduction in refining unit throughput has not affected ethylene unit load. We will continue to follow up and report.

Sample Description:

Output: Output generally refers to the actual quantity produced by manufacturing enterprises that meets relevant standards within a certain period.

The cracking C5 output statistics from chempricehub.com represent the total output of all industrial cracking C5 producers in China (including self-use enterprises).

The cracking C5 output data from chempricehub.com are primary statistics, covering 38 domestic enterprises with a sample coverage rate of 100%. The statistical period is from last Friday to this Thursday.

    With two ethylene units down, pyrolysis C5 supply tightens next week, lowering capacity utilization. June forecast still 306.7kt, but downstream demand may shift margins—July output recovery could ease pressure.
