9902.11.57 - Industrial grade nitrocellulose, having a nitrogen content of less than 12.4 percent on a dry weight basis, damped with an alcohol content of 28 to 32 percent by weight (CAS No. 9004-70-0), presented in fiber drums each containing 85 kg, 100 kg, 110 kg or 120 kg of such nitrocellulose, certified by the importer as made from at least 50 percent cotton linter or wood pulp and as having each such drum lined with an antistatic plastic bag and equipped with a coupling for mechanical unloading (provided for in subheading 3912.20.00)

This HTS category, 9902.11.57, specifically classifies industrial grade nitrocellulose that meets precise technical specifications. The nitrocellulose must have a nitrogen content below 12.4 percent on a dry weight basis and be damped with an alcohol content ranging from 28 to 32 percent by weight. This particular product is presented in standardized fiber drums of specific weights (85 kg, 100 kg, 110 kg, or 120 kg) and requires certification by the importer regarding its composition (at least 50 percent cotton linter or wood pulp) and packaging (antistatic plastic bag lining and a mechanical unloading coupling). Its classification under Chapter 99 indicates it is subject to temporary legislation, modifications, or additional import restrictions, referencing its primary classification under subheading 3912.20.00.

As this node is a leaf within the HTS, it does not have subcategories. Its distinctiveness from sibling categories at the HTS Database Root level is absolute; sibling categories at this level typically represent vastly different product groups, such as live animals (e.g., horses, bovine animals, swine) or other basic commodity classifications. The extensive list of siblings underscores the granular nature of the HTS system, where each code represents a unique product or a narrowly defined group of products. The focus for this specific entry is on the precise chemical and physical attributes, packaging, and importer certifications that collectively identify this industrial grade nitrocellulose, distinguishing it from any other nitrocellulose or chemical product that might fall under different HTS headings or subheadings.
