1501 - Pig fat (including lard) and poultry fat, other than that of heading 0209 or 1503:

This HTS category, 1501, encompasses pig fat, including lard, and poultry fat. It is crucial to note that this heading specifically excludes rendered pig fat (lard) and other pig fats of heading 0209 (which covers fresh, chilled, or frozen pig fat and pig meat with bone) and fat of swine and poultry which are the fatty substances of heading 1503. This means that while 1501 deals with the fats themselves, exclusions apply to certain preparations or specific forms found elsewhere.

When classifying goods, it is important to distinguish this category from its sibling entries. For instance, sibling categories within Chapter 15 will cover other types of animal or vegetable fats and oils, or their cleavage products, each with distinct tariff treatments. Similarly, headings in earlier chapters of Section III, such as Chapter 01, deal with live animals, not their derived fat products. The focus here is strictly on the fat and lard derived from pigs and poultry, excluding specific raw forms or pre-existing preparations.

Within the 1501 heading, further subdivisions exist to refine classification based on the type of fat. The subcategories differentiate between lard (1501.10.00.00), which is specifically rendered pig fat, and other pig fat (1501.20.00), which would include fat from pigs that is not classified as lard. The residual category, "Other" (1501.90.00.00), captures poultry fat and any other pig fat not specifically enumerated in the preceding subheadings, ensuring a comprehensive classification of all eligible products.
