1510 - Other oils and their fractions, obtained solely from olives, whether or not refined, but not chemically modified, including blends of these oils and fractions with oils or fractions of heading 1509:

Heading 1510 encompasses a specific range of olive-derived oils and their fractions that fall outside the scope of heading 1509. This category is reserved for oils and fractions obtained *solely* from olives, which have undergone refining processes but have not been chemically modified. Importantly, this heading also includes blends of these purely olive-derived oils and fractions with oils or fractions that originate from heading 1509. The key distinction lies in the origin of the primary component – strictly olives – and the absence of chemical modification, even if refined.

This classification stands distinct from its sibling categories within Section III, which cover a vast array of animal and vegetable fats and oils, as well as their cleavage products and waxes. For instance, headings like 1501 (pork and poultry fat) or 1508 (ground-nut oil) would be used for oils derived from different sources. Heading 1510 specifically isolates the treatment and origin of olive oils and their fractions, ensuring accurate tariff application for this particular group of products.

Within heading 1510, two subcategories provide further specificity. Subheading 1510.10 covers "Crude olive pomace oil," denoting the unrefined oil extracted from the residue of olive pressing. All other olive oils and fractions that meet the criteria of heading 1510 but are not crude olive pomace oil are classified under subheading 1510.90, "Other." This division allows for more granular tariff treatment based on the processing stage of these specialized olive-derived oils.
