HS Code for Sulphite turpentine

Sulphite turpentine is classified under HS code 3805.90. This code resides within Chapter 38, which covers miscellaneous chemical products. Heading 3805 specifically addresses terpenic oils produced by the distillation or other treatment of coniferous woods. While 3805.10 covers gum, wood, or sulfate turpentine, the subheading 3805.90 acts as a residual category for other terpenic oils, including sulphite turpentine, which is a byproduct of the sulphite pulping process. The classification depends on the method of extraction and the resulting chemical profile. Sulphite turpentine contains various terpenes and is often used as a solvent or a raw material in the chemical industry for the synthesis of camphor or resins. Because it is a byproduct of wood pulp manufacture rather than direct distillation of oleoresins, it is excluded from the primary turpentine codes. Importers must provide chemical analysis to distinguish it from other terpenic oils to ensure the correct application of 3805.90. The Explanatory Notes for heading 3805 state that this heading includes products obtained during the pulping of coniferous wood by the sulphite process. This specific mention makes 3805.90 the legally correct classification. It is important to note that if the product were highly refined to a single chemical constituent, such as pure pinene, it might be classified in Chapter 29 as a separate chemically defined compound. However, as a crude byproduct containing a mixture of terpenes, it remains in 3805.90. This code is essential for tracking the trade of industrial wood byproducts.

Products Included

• Crude sulphite turpentine
• Crude dipentene
• Crude para-cymene
• Terpenic oils from sulphite pulping
• Mixed terpenic byproducts n.e.c.

Common Misclassification

Sulphite turpentine is most commonly misclassified under 3805.10, which is strictly for gum, wood, or sulfate turpentine. It can also be confused with pine oil (3805.90) or specific hydrocarbons in 2902 if the product has been significantly refined to isolate a single terpene like limonene.

FAQ

What is the HS code for Sulphite turpentine?

The HS code for sulphite turpentine is 3805.90.

How does it differ from sulfate turpentine?

Sulfate turpentine is a byproduct of the Kraft (sulfate) pulping process and is classified under 3805.10, whereas sulphite turpentine comes from the sulphite process and falls under 3805.90.
