9902.09.13 - Plaster mold release agent made from propan-2-ol (CAS No. 67-63-0), 2-methylpropan-1-ol (CAS No. 78-83-1), 2-methoxy-methylethyl acetate (CAS No. 108-65-6), hexadecanoic acid (CAS No. 57-10-3), octadecanoic acid (CAS No. 57-11-4) and other ingredients (provided for in subheading 3403.99.00)

This HTS classification, specifically 9902.09.13, pertains to a specific formulation of a plaster mold release agent. The product is characterized by its composition, which includes propan-2-ol, 2-methylpropan-1-ol, 2-methoxy-methylethyl acetate, hexadecanoic acid, and octadecanoic acid. Crucially, any additional ingredients present in this formulation fall under the provision of subheading 3403.99.00, indicating a complex mixture where the primary function as a mold release agent is paramount for its classification within this temporary provision.

As a Chapter 99 provision, this classification falls under temporary legislation and special classification provisions, distinct from the permanent tariff classifications found in Chapters 1-98. Therefore, it does not directly compete with the sibling categories listed, such as live animals or other general merchandise. The siblings represent fundamental product categories in international trade, whereas 9902.09.13 is a specific, temporary classification for a specialized chemical product with particular import restrictions or conditions. Its uniqueness lies in its application as a mold release agent and its specific, detailed chemical composition, setting it apart from broader chemical classifications.

This entry is a leaf node, meaning it has no further subcategories within the HTS. Classification under 9902.09.13 is therefore definitive for the described plaster mold release agent. Any product meeting the precise chemical composition and functional criteria outlined in the description will be classified here. The presence of the "provided for in subheading 3403.99.00" note signifies that while the core classification is temporary, the general nature of the "other ingredients" aligns with the broader scope of lubricants and release agents, further solidifying its functional identity.
