HS Code for LABSA

Linear Alkylbenzene Sulphonic Acid, commonly known as LABSA, is classified under HS code 3402.31. This classification falls within Chapter 34, which covers soap, organic surface-active agents, and washing preparations. Specifically, heading 3402 is designated for organic surface-active agents (other than soap). LABSA is a synthetic surfactant characterized by its anionic properties, meaning it carries a negative charge in aqueous solutions. Under the 2022 HS nomenclature updates, subheading 3402.31 was specifically created to identify linear alkylbenzene sulphonic acids and their salts. The classification is based on the chemical structure of the molecule, which consists of a hydrophilic sulfonic acid group attached to a hydrophobic linear alkylbenzene chain. This product is a critical precursor in the manufacturing of synthetic detergents and liquid cleaners, and its classification is determined by its chemical identity as an anionic surface-active agent.

Common Misclassification

LABSA is often misclassified under HS code 3817.00, which covers mixed alkylbenzenes and mixed alkylnaphthalenes. While LABSA is derived from alkylbenzenes, the addition of the sulfonic acid group transforms it into a surface-active agent, moving it from Chapter 38 to Chapter 34. Another common error is using 3402.39, which is the residual category for "other" anionic agents. Since LABSA has a specific dedicated subheading (3402.31), using the general category is a violation of GRI 3(a), which requires the most specific description. Finally, it should not be confused with pure sulphuric acid under 2807.00, despite containing a sulfonic group.

FAQ

What is the HS code for LABSA?

The specific HS code for Linear Alkylbenzene Sulphonic Acid (LABSA) and its salts is 3402.31.

Is LABSA classified as a hazardous chemical for shipping?

While the HS code identifies the product for customs, LABSA is chemically corrosive and usually requires specific UN numbers (like UN 2586) for transport safety, though this does not change its 3402.31 classification.
