HS Code 03.05 – Fish, dried, salted or in brine; smoked fish, whether or not cooked before, or during the smoking process

HS code 0305 is a 4-digit heading in the Harmonized System that covers: Fish, dried, salted or in brine; smoked fish, whether or not cooked before, or during the smoking process. Heading 0305 comprehensively covers fish that have undergone specific preservation methods: drying, salting, or brining, as well as smoked fish, irrespective of whether they were cooked before or during the smoking process. This classification is crucial in international trade as it distinguishes these preserved products from fresh, chilled (0302), or frozen fish (0303), and also from more extensively prepared or processed fish products found in Chapter 16 (e.g., canned fish, fish pastes). The scope is broad, encompassing whole fish, fillets, or other pieces, as long as the primary preservation method falls under drying, salting, brining, or smoking. Key sub-categories include stockfish (air-dried cod), bacalao (salted and dried cod), various brined anchovies or sardines, and a wide array of smoked fish like salmon, herring, and mackerel. This classification is vital for trade compliance, impacting tariffs, import quotas, and sanitary regulations, as preserved fish often have different shelf-life, storage, and handling requirements compared to their fresh counterparts. Historically, these preservation methods were essential for food security and enabling long-distance trade before refrigeration, a significance that continues today for certain markets and traditional cuisines. This heading sits within Chapter 3, which focuses on fish and aquatic invertebrates, emphasizing products in their raw or simply preserved state, making 0305 a natural extension of the chapter's scope by covering basic, traditional preservation techniques.

Dried cod fillets, salted anchovies in brine, smoked salmon fillets, dried sardines, salted mackerel, bacalao (salted cod), stockfish (dried cod), smoked herring (kippers), salted pollock, dried tuna flakes, smoked trout, salted hake, dried sprats, smoked haddock, salted pilchards, dried whitefish, smoked eel, salted ling, dried barracuda, smoked mackerel fillets, dried cuttlefish (if fish not mollusc - careful here, stick to fish), dried shark fins (if not further processed), salted mullet, smoked catfish, dried croaker.

Common misclassifications for products under HS 0305 often arise from confusing the level of processing. Traders sometimes mistakenly classify dried, salted, or smoked fish under 0302 (fresh or chilled fish) or 0303 (frozen fish), ignoring the specific preservation methods. Another frequent error is classifying these products under 1604, which covers 'prepared or preserved fish' (e.g., canned fish, fish in sauces, or fish pastes). The key distinction is that 0305 products are preserved solely by drying, salting, brining, or smoking, without further preparation like canning, adding sauces, or being processed into pastes. Misclassifying inedible fish waste or by-products as 0305 instead of 0511 is also a pitfall.

In 2025, the top exporters of HS code 0305 in UN Comtrade data were Poland ($1.3B, 19% of world exports), Norway ($1.1B) and China ($417M). World exports came to about $6.9B, adding countries' reported figures and partner-based estimates for those that did not report (UN Comtrade data). Countries that did not report 2025 data are estimated from partner records, which can understate them.

In 2025, the top importers of HS code 0305 in UN Comtrade data were Germany ($987M, 14% of world imports), Portugal ($709M) and Italy ($699M). World imports came to about $7.0B, adding countries' reported figures and partner-based estimates for those that did not report (UN Comtrade data). Countries that did not report 2025 data are estimated from partner records, which can understate them.

HS code 0305 is a 4-digit heading under Chapter 03 of the Harmonized System. The first 2 digits (03) identify the chapter, and digits 3-4 (05) specify the heading. This code contains multiple 6-digit subheadings for precise product classification.
