HS-4 · Heading
0303 — Fish; frozen, excluding fish fillets and other fish meat of heading 0304
Chapter 03: Fish and crustaceans
Plain-language overview
Use HS-4 0303 when importing frozen fish, such as whole Pacific salmon or frozen tuna, that do not fall under fillets or other fish meat specified in heading 0304. This classification is crucial for ensuring compliance with customs regulations and avoiding penalties.
When determining the correct HS-6 code, consider the specific type of fish you are importing. For example, if you are importing frozen sockeye salmon, you would use HS-6 030311. If it's another type of Pacific salmon, like pink or chum, then HS-6 030312 is more appropriate.
The distinction between various HS-6 lines can be subtle. For instance, HS-6 030341 covers frozen albacore or longfinned tunas, while HS-6 030342 is for yellowfin tunas. Ensure you accurately identify the species to select the correct code, as misclassification can lead to delays or additional duties.
