HTS heading 3805 is a broad product category for certain terpene-based oils and related products obtained mainly from coniferous wood. It includes gum, wood, or sulfate turpentine; other terpenic oils made by distilling or otherwise treating coniferous woods; crude dipentene; sulfite turpentine; other crude para-cymene; and pine oil in which alpha-terpineol is the main constituent.
The 4-digit heading is only the starting point. To select the more specific 8-digit HTS code, compare the product with the heading’s subcategories and identify the relevant product type, such as the kind of turpentine or terpene product, whether it is crude, and the applicable composition or constituent description. Product specifications, manufacturing records, and laboratory data may be needed to distinguish closely related subheadings. The final classification should be checked against the current HTSUS and, when uncertain, reviewed by a customs broker or classification specialist.
What to check
- Confirm that the product is derived from coniferous wood or otherwise fits the heading’s listed product families; do not classify a general fragrance or essential oil here solely because it contains terpenes.
- Identify the product’s commercial and technical name, manufacturing process, and condition, including whether it is described as crude, refined, distilled, or otherwise treated.
- Check the product’s composition and any required constituent information, especially for pine oil described by its main alpha-terpineol constituent.
- Compare the product against every applicable 6-digit and 8-digit subheading, using the wording of the current HTSUS rather than relying only on a supplier’s tariff code.
- Keep a specification sheet, safety data sheet, certificate of analysis, and process description to support the classification; request broker or customs authority guidance if the distinctions remain unclear.

How to find your code in this category
A heading is a product category. To get the exact duty, narrow from this 4-digit heading to a sub-category (usually by material), then open the 8-digit code that matches your product.
Open any code in the tables below to see its exact duty rate, a duty calculator (enter your shipment value → estimated duty and landed cost), the rate-change history chart, and the country-by-country breakdown (including Section 301/232 add-on duties).
Why you have to click in: a single category can contain products with very different duties. The rate depends on the specific product — its material and construction — and on the country of origin, and those only get pinned down at the 8-digit code level. That is why this page points you to codes instead of showing one rate for the whole category.
