1515.60.05.00 - Microbial fats and oils and their fractions

This HTS subheading, 1515.60.05.00, specifically classifies microbial fats and oils, along with their fractions. These are fats and oils derived from microorganisms, such as bacteria, yeasts, or algae, and are distinct from animal or vegetable-based oils. The classification applies whether these microbial oils are refined or not, as long as they have not undergone chemical modification.

This category is distinguished from its sibling categories by its origin. While other subheadings within 1515.60 cover fixed vegetable oils like linseed, corn, castor, and sesame oils, this particular code is exclusively for oils derived from microbial sources. It serves as a distinct grouping for these biotechnologically produced or extracted oils, ensuring accurate customs reporting for a growing class of raw materials.

As a leaf node in the HTS structure, 1515.60.05.00 does not have further subdivisions. Therefore, classification within this code relies on confirming the microbial origin of the fat or oil and ensuring it is not chemically modified. This includes products intended for various industrial applications, such as biofuels, lubricants, or ingredients in cosmetics and pharmaceuticals, where a pure microbial fat or oil is required.
