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

According to data from the General Administration of Customs, isobutyraldehyde is classified under HS code 2912.19.00.90 (Other acyclic aldehydes). The official customs reporting framework does not disaggregate isobutyraldehyde separately; instead, it is aggregated with other acyclic aldehydes, such as n-butyraldehyde, for statistical purposes. Consequently, no official public data on independent exports of isobutyraldehyde are available.

For the category "Other unnamed acyclic aldehydes containing no other oxygen function," China's export volume in September 2026 was 1,065.26 metric tons. Based on industry research estimates, isobutyraldehyde accounted for a small portion of this total, with an estimated export volume ranging from 30 to 80 metric tons, primarily driven by small-lot orders destined for Southeast Asian markets.
