HTS code 1518.00 classifies imports of: Animal, vegetable or microbial fats and oils and their fractions, boiled, oxidized, dehydrated, sulfurized, blown, polymerized by heat in vacuum or in inert gas or otherwise chemically modified, excluding those of heading 1516; inedible mixtures or preparations of animal, vegetable or microbial fats or oils or of fractions of different fats or oils of this chapter, not elsewhere specified or included:. This line sits within Chapter 15 (Animal, vegetable or microbial fats and oils and their cleavage products; prepared edible fats; animal or vegetable waxes), Section III (Animal or Vegetable Fats and Oils), and is catalogued as a heading in the USITC 2026 Basic Edition. The schedule specifies ad valorem (percentage-of-value) duty for this line. Chapter 15 covers a broad category with many neighboring tariff lines, so double-check the classification against the closest matches before filing.

The general (MFN / Column 1 General) rate for HTS 1518.00 is Free, which applies to most trading partners of the United States. No special preferential rate is listed for this line, so FTA origin alone will not reduce the general duty. Because the general rate is Free, most imports under this code enter the US without duty, though anti-dumping, countervailing, or Section 301 tariffs can still apply depending on country of origin.

Beyond the published rate, importers should check for Section 201 safeguards, Section 301 China tariffs, and any active AD/CVD orders that can materially change the real landed cost. Always verify the classification with a licensed customs broker before committing to a supply contract, this page is a research tool, not a customs ruling.
