9902.10.53 - Mixtures of methyl esters of C16-C18 and C18 unsaturated fatty acids (CAS No. 67762-38-3) and methyl hexadecanoate (Methyl Palmitate) (CAS No. 112-39-0) (provided for in subheading 3824.99.41) derived from coconut, palm-kernel or palm oil, used other than as a fuel

This HTS classification, 9902.10.53, specifically covers mixtures of methyl esters derived from coconut, palm-kernel, or palm oil. These mixtures are characterized by containing methyl esters of C16-C18 and C18 unsaturated fatty acids (identified by CAS No. 67762-38-3), along with methyl hexadecanoate (Methyl Palmitate, CAS No. 112-39-0). Crucially, these substances are intended for use other than as fuel and are provided for in subheading 3824.99.41.

Within the broader context of Chapter 99, which pertains to temporary legislation and trade agreement modifications, this specific subheading functions as a temporary provision or modification related to a particular class of goods. Unlike the primary product-based headings in the initial chapters of the HTS (such as Chapter 1 for live animals), this category is a specialized provision under the temporary legislation chapter, indicating a specific trade policy or restriction applied to these particular chemical mixtures. Its purpose is to manage or account for these specific fatty acid methyl ester mixtures under unique trade circumstances.

As this is a leaf node, there are no further subdivisions. The classification is precisely defined by the chemical composition and intended use as described. Therefore, distinguishing this category from potential siblings would involve examining other entries within Chapter 99 to understand the scope of other temporary provisions, or by referencing the parent subheading 3824.99.41 to understand the underlying commodity classification that this temporary code modifies. The key classification criteria here are the specific chemical components and their non-fuel application.
