Frozen, Raw: The shrimp are uncooked and sold frozen.
IQF (Individually Quick Frozen): This processing method means that each individual shrimp is frozen separately, preventing them from clumping together in a solid block. This makes it easy for the user to take out and thaw only the exact amount needed.
Head Off / Unpeeled: The head has been removed, but the shell and tail are still on the shrimp (also known as "shell-on" or "headless, shell-on"). This is a common form for wholesale or retail, as the shell helps protect the meat during freezing and cooking, and retains flavor.
