FSIS applies US standards of identity to many sausage types — such as frankfurters, bologna, and salami — meaning imported products must conform to the same composition and labeling rules as domestically produced equivalents. Products that do not meet a defined standard may still be admissible but must be labeled with a descriptive name rather than a standardized one.

Blood sausages and preparations where blood is the primary or a significant ingredient fall within this same SITC heading alongside conventional meat and offal sausages. However, at the HTS level, blood-based preparations may be assigned to distinct tariff lines with different duty rates, so importers should confirm the precise HTS classification based on the product's actual formulation before filing entry.
