HS code 0511.91 is the 6-digit subheading for animal products, of fish or crustaceans, molluscs or other aquatic invertebrates, dead animals of chapter 03, unfit for human consumption. It is used for fish meal, fish oil (non-food grade), shrimp shells, crab shells and squid ink (industrial use).
What HS 0511.91 covers
This category encompasses various animal products derived from fish, crustaceans, molluscs, or other aquatic invertebrates, specifically those unfit for human consumption, including dead animals of Chapter 03. These by-products are crucial for industries like animal feed, aquaculture, and fertilizer production, transforming what would otherwise be waste into valuable resources. The trade involves processing raw aquatic materials into forms such as meals, oils, or chitin. Importers are typically manufacturers of pet food, fish feed, or agricultural inputs. Exporters are countries with significant fishing industries or aquaculture operations that efficiently process their by-products. Key aspects include sustainable sourcing, processing efficiency, and adherence to quality standards for non-food applications, ensuring environmental responsibility and economic value.

How these figures are built
109 countries reported 2025 trade to UN Comtrade in HS 2022, and their own totals are used. Countries that did not report are estimated from what other countries recorded trading with them. Those estimates miss trade with other non-reporting countries, so they can be low, and a non-reporting country can rank higher than shown or be missing from the list. World totals add both and leave out trade between two non-reporting countries. Figures are in current US dollars; reported imports are mostly valued CIF and exports FOB, and exports include re-exports. The UN Comtrade links show the underlying records; they can also list a few reporters left out here (regional groups and older HS editions).
