HS Code 2917.19 – Acids; acyclic polycarboxylic acids; n.e.c. in item no. 2917.1
HS code 2917.19 is the 6-digit subheading for acids, acyclic polycarboxylic acids, n.e.c. in item no. 2917.1. It is used for succinic acid, glutaric acid, malonic acid, tartaric acid and citric acid.
What HS 2917.19 covers
This HS code acts as a residual category for "other" acyclic polycarboxylic acids and their derivatives not specifically enumerated in the preceding codes within subheading 2917.1. It covers a diverse array of organic compounds, each with unique industrial applications, ranging from specialty polymers and plasticizers to food additives and pharmaceutical intermediates. Importers are typically specialized chemical manufacturers or research institutions seeking specific compounds for niche applications or R&D. Exporters are often smaller, specialized chemical synthesis companies or larger firms producing a wide portfolio of fine chemicals. The trade in these "not elsewhere specified" acids is characterized by lower volumes but often higher unit values, driven by specific performance requirements. Understanding the exact chemical identity and purity is paramount, as regulatory and application requirements can vary significantly for each compound within this broad grouping.

Codes often confused with 2917.19
Common mistake. This code is frequently confused with other specific acyclic polycarboxylic acids like 291711 (oxalic acid) or 291712 (adipic acid) if the specific chemical is not clearly identified, or with 291819 (other carboxylic acids with alcohol function) if the polycarboxylic nature is not recognized.
Top exporters and importers of HS code 291719, 2025
In 2025, the largest exporter of HS code 291719 in UN Comtrade data was China, with 39% of world exports; the largest importer in UN Comtrade data was the United States, with 13% of world imports. Countries that did not report 2025 data are estimated from partner records, which can understate them.

How these figures are built
109 countries reported 2025 trade to UN Comtrade in HS 2022, and their own totals are used. Countries that did not report are estimated from what other countries recorded trading with them. Those estimates miss trade with other non-reporting countries, so they can be low, and a non-reporting country can rank higher than shown or be missing from the list. World totals add both and leave out trade between two non-reporting countries. Figures are in current US dollars; reported imports are mostly valued CIF and exports FOB, and exports include re-exports. The UN Comtrade links show the underlying records; they can also list a few reporters left out here (regional groups and older HS editions).
