Classification of fish waste under HS 0511.91

HS code 0511.91 is utilized for the classification of animal products of fish, crustaceans, molluscs, or other aquatic invertebrates that are unfit for human consumption. Chapter 5 of the Harmonized System covers products of animal origin not elsewhere specified or included. Heading 0511 is a broad category for animal products not fit for human consumption, and subheading 0511.91 is the specific carve-out for aquatic species. This classification is essential for distinguishing between edible fish parts and industrial or agricultural raw materials. The determination of whether a product is unfit for human consumption can be based on the nature of the product, such as scales or shells, or its condition, such as being decayed or contaminated. This code is often used for materials destined for the production of fertilizers, glues, or technical oils. According to the General Interpretative Rules, specifically GRI 1, the classification is governed by the legal notes of Section I, which excludes products fit for human consumption from this chapter. Therefore, any fish waste that is still edible or intended for food use must be classified in Chapter 3. This code serves as a vital category for the rendering and animal byproduct industries.

Codes often confused with 0511.91

Common mistake. A common error is classifying fish waste under HS code 2301.20. While 2301.20 covers flours, meals, and pellets of fish used for animal feed, 0511.91 is for the raw, unprocessed waste. Another misclassification occurs with 0305, which is only for fish products that remain fit for human consumption.

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).
