HS Code for Chemical preparations

HS code 3824.99 serves as a residual category for chemical products and preparations of the chemical or allied industries, including those consisting of mixtures of natural products, not elsewhere specified or included. Classification here requires that the product is a mixture or a preparation that does not meet the criteria for a single chemically defined element or compound found in Chapters 28 or 29. This code is one of the most diverse in the Harmonized System, covering a vast array of industrial and commercial chemical blends. To be classified here, the preparation must not be intended for a specific use that has its own dedicated heading, such as diagnostic reagents (3822) or insecticides (3808). The technical composition and the intended industrial application are the primary drivers for classification under this subheading.

Products Included

• Non-refractory mortars and concretes
• Foundry core binders based on natural resinous products
• Mixed alkylbenzenes and mixed alkylnaphthalenes
• Chemical additives for cement or concrete
• Ready-to-use stencil correction fluids

Common Misclassification

A frequent error is classifying pure chemicals under 3824.99. Pure chemicals must be classified in Chapter 28 (Inorganic) or Chapter 29 (Organic). Another common mistake involves HS code 3824.91, which is specifically for mixtures containing halogenated derivatives of methane, ethane, or propane. If a preparation has a specific therapeutic use, it should be moved to Chapter 30 (Medicaments) rather than 3824.99.
