Headline numbers: a record-breaking first half, then a measured Q3 cool-down

China's chemical export complex has spent the first three quarters of 2026 rewriting the playbook. According to customs data compiled by CITIC Securities and the General Administration of Customs, the country shipped RMB 1,604.5 billion of chemical products abroad between January and June — a 13.7% year-on-year increase and the strongest first half on record. June alone set an all-time monthly high of RMB 302.5 billion, up 22.7% on the year and 3.4% on the month. That single month accounted for more than 18% of the entire first-half tally, a concentration that has not been seen since the 2021 container crunch.

The heat did not survive the summer intact. July exports came in at RMB 266.4 billion, up 8.4% on the year but down 11.9% sequentially. Cumulative shipments for January–July reached RMB 1,870.9 billion (+13.0%). The August data confirmed the cooldown: RMB 263.4 billion, +6.8% year-on-year — still positive, but the slowest pace since March 2025. By September, the broader trade complex re-accelerated — overall exports of goods rose roughly 25% on the year and high-tech product exports surged 91.8% — but the chemical line did not fully participate in that rebound, reflecting a market that is rotating rather than uniformly booming.

Put differently: 2026 is not a year of indiscriminate growth. It is a year of structural reset. Two product families — plastics and articles thereof (HS Chapter 39) and organic chemicals (HS Chapter 29) — contributed roughly 74% of the incremental export value in June. Within those two chapters, the gains are concentrated in perhaps a dozen SKUs. The rest of the catalogue is flat or negative.
