HS Code 38.23 – Industrial monocarboxylic fatty acids; acid oils from refining; industrial fatty alcohols

HS code 3823 is a 4-digit heading in the Harmonized System that covers: Industrial monocarboxylic fatty acids; acid oils from refining; industrial fatty alcohols. Heading 3823 encompasses industrial monocarboxylic fatty acids, acid oils from refining, and industrial fatty alcohols. These products are crucial raw materials derived primarily from the hydrolysis, distillation, or hydrogenation of natural fats and oils (animal or vegetable) or, in some cases, from petroleum. This classification is vital for industries manufacturing soaps, detergents, cosmetics, lubricants, plastics, paints, and certain food additives. The term 'industrial' is key, distinguishing these bulk chemicals from highly purified or pharmaceutical-grade counterparts that might fall under other chapters. The scope includes widely used compounds like stearic acid, oleic acid, palmitic acid, cetyl alcohol, and stearyl alcohol, as well as the by-products of oil refining, such as acid oils. This heading replaced the former 1519 for these specific products, which is an important historical context for classification. Compliance under 3823 is significant for managing supply chain costs, adhering to environmental regulations (e.g., regarding sustainable sourcing of palm oil derivatives), and navigating technical specifications for industrial applications. As part of Section VI, this heading represents a critical segment of processed organic chemicals, bridging the gap between basic agricultural commodities and advanced manufactured goods, highlighting the transformation of natural resources into versatile industrial intermediates.

A common misclassification involves confusing 3823 with Chapter 15 (Animal or vegetable fats and oils and their cleavage products). While related, Chapter 15 covers the *raw fats and oils* and simpler cleavage products like crude glycerol, whereas 3823 is for *industrial fatty acids and alcohols* which are more processed. For instance, crude palm oil is 1511, but palmitic acid derived from it is 3823. Another mistake is classifying specific, pure, chemically defined fatty acids or alcohols under Chapter 29 (Organic chemicals) if they are industrial mixtures or less pure forms. The 'industrial' aspect of 3823 is key, differentiating it from highly purified organic compounds.

In 2025, the top exporters of HS code 3823 in UN Comtrade data were Indonesia ($7.6B, 42% of world exports), Malaysia ($4.5B) and the Netherlands ($1.6B). World exports came to about $17.9B, adding countries' reported figures and partner-based estimates for those that did not report (UN Comtrade data). Countries that did not report 2025 data are estimated from partner records, which can understate them.

In 2025, the top importers of HS code 3823 in UN Comtrade data were China ($3.8B, 20% of world imports), Malaysia ($1.9B) and the Netherlands ($1.7B). World imports came to about $18.8B, adding countries' reported figures and partner-based estimates for those that did not report (UN Comtrade data). Countries that did not report 2025 data are estimated from partner records, which can understate them.

HS code 3823 is a 4-digit heading under Chapter 38 of the Harmonized System. The first 2 digits (38) identify the chapter, and digits 3-4 (23) specify the heading. This code contains multiple 6-digit subheadings for precise product classification.
