1514 - Rapeseed, colza or mustard oil, and fractions thereof, whether or not refined, but not chemically modified:

This HTS category, 1514, encompasses various types of rapeseed, colza, and mustard oils, as well as their separated fractions. Crucially, these oils must not have undergone chemical modification; refinement is permitted. This includes a broad spectrum of vegetable oils derived from these specific seeds, used in a variety of industrial and sometimes food-related applications where the inherent chemical structure of the oil is preserved.

Unlike sibling categories within Section III, which deal with other animal and vegetable fats and oils or their cleavage products, this heading is specifically limited to oils originating from rapeseed, colza, or mustard seeds. It distinguishes itself from categories covering other oilseeds or their refined, chemically altered derivatives. The key differentiator is the source material and the absence of chemical modification, which is a critical determinant for accurate classification.

Within this heading, further subdivision is made to distinguish between oils with low erucic acid content and other types. This distinction is often based on specific compositional standards, such as the percentage of erucic acid, which can impact the suitability and application of the oil. The "Other" subcategory captures all remaining rapeseed, colza, and mustard oils that do not meet the criteria for low erucic acid oil.
