According to data from the General Administration of Customs, the HS code for isobutyraldehyde is 2912190090 (Other).

According to data from the General Administration of Customs of China, isobutyraldehyde falls under HS code 2912.19.00.90 (Other acyclic aldehydes). The customs’ publicly available statistical categories do not disaggregate isobutyraldehyde; it is aggregated with other acyclic aldehydes such as n-butyraldehyde. Consequently, no official public export data exist for isobutyraldehyde as a standalone item.

For September 2026, imports of “Other acyclic aldehydes containing no other oxygen function” (not elsewhere specified) totaled 137 tonnes. Industry surveys estimate that isobutyraldehyde accounted for only a negligible portion of this volume in September, reflecting sporadic replenishment orders rather than routine trade flows.

For the period January–September 2026, estimated cumulative imports of isobutyraldehyde ranged from several hundred tonnes (typically between 200 and 600 tonnes), exhibiting significant month-to-month volatility, with near-zero import volumes recorded in many months.
