1605.10.20.22 - C. opilio (small)

This HTS classification pertains to prepared or preserved snow crab meat from species such as *Chionoecetes opilio* (often referred to as snow crab), specifically when packaged in airtight containers. This category encompasses products where the crab meat has undergone processing, such as cooking or chilling, and is then sealed in cans, pouches, or other airtight packaging to ensure preservation and extend shelf life. The "small" designation in the description refers to the size of the individual crab pieces or the overall presentation within the container, distinguishing it from larger cuts or whole crab preparations.

This category is differentiated from its sibling, 1605.10.20.25 "Other," which would cover prepared snow crab meat not packaged in airtight containers. The key distinguishing factor is the method of preservation and packaging; 1605.10.20.22 is strictly for goods sealed to prevent air and contaminant ingress, whereas the "Other" category would encompass items like refrigerated crab meat salads or crab meat simply packed in brine or oil without hermetic sealing.

As this is a leaf node within the HTS, there are no further subcategories. Classification at this level is determined by the species of crab (snow crab), the form (meat), and crucially, the packaging method (in airtight containers). This precise delineation ensures accurate tariff application for imported and exported snow crab products.
