Last updated: August 2026 dataPeptones — partially hydrolyzed proteins used extensively as microbiological culture media components and fermentation nutrients — anchor this heading alongside broader protein derivatives not elsewhere specified and hide powder (whether chromed or not). Hide powder serves as a reference material in the leather and tanning industry, while protein derivatives find roles in food technology, diagnostics, and specialty chemical manufacturing. The diversity of end-uses means that classification often hinges on the degree of hydrolysis and the specific protein source, distinguishing these materials from intact proteins or finished pharmaceutical preparations.

Peptones are proteins that have been partially hydrolyzed — broken into shorter peptide chains — typically by enzymatic or acid treatment. For classification, the key factors are the degree of hydrolysis and the intended function: peptones used as culture media components remain in this heading, whereas fully hydrolyzed amino acid preparations or finished pharmaceutical proteins generally fall elsewhere.
Both chromed and unchromed hide powders fall within the same SITC heading. However, chromed hide powder may attract additional scrutiny related to chromium content under environmental or hazardous-materials regulations depending on the port and end-use. Importers should verify applicable EPA or OSHA requirements for chromium-containing materials before entry.
