Guts, bladders and stomachs of animals (other than fish); whole and pieces thereof, fresh, chilled, frozen, salted, in brine, dried or smoked

HS code 0504 is a 4-digit heading in the Harmonized System that covers: Guts, bladders and stomachs of animals (other than fish); whole and pieces thereof, fresh, chilled, frozen, salted, in brine, dried or smoked. Heading 0504 specifically covers guts, bladders, and stomachs of animals (excluding fish), whether whole or in pieces, and in various states of preservation: fresh, chilled, frozen, salted, in brine, dried, or smoked. This classification is critical for distinguishing these particular animal organs from other edible offal or animal products not elsewhere specified. The scope is precise: it only includes guts, bladders, and stomachs, explicitly excluding fish products, which fall under Chapter 3. The specified preservation methods are exhaustive, allowing for a wide range of commercially traded forms. Key sub-categories include natural sausage casings (e.g., hog, sheep, beef casings), tripe (unprepared for direct consumption), and animal bladders for various uses. Accurate classification is paramount for trade compliance due to stringent sanitary and veterinary controls, food safety regulations, and potential disease transmission risks associated with animal by-products. Historically, these items have been essential in traditional food processing, particularly sausage making, and have also become crucial for pharmaceutical industries (e.g., heparin extraction from pig intestines). This heading perfectly aligns with Chapter 5's focus on raw or minimally processed animal products, highlighting specific animal parts and allowed preservation methods.

Fresh beef intestines, chilled hog casings, frozen sheep guts, salted pig bladders, dried cow stomachs, in brine lamb casings, smoked pork chitterlings (unprepared), whole beef stomachs, pieces of hog guts for sausage making, sheep casings for frankfurters (unprepared), natural sausage casings (unprepared), tripe (unprepared for direct consumption), raw animal bladders for packaging, animal guts for pharmaceutical extraction, animal stomachs for pet treats (unprocessed), cleaned beef bung, salted pork intestines, frozen veal stomachs, dried goat guts, in brine natural casings, smoked beef tripe (raw), raw pig maws, cleaned lamb stomachs, chilled bovine guts, preserved natural casings.

Traders frequently confuse goods under 0504 with 'edible offal' classified under HS 0206. While some items like stomachs or guts might be considered edible offal, 0504 is more specific to 'guts, bladders and stomachs' and includes a wider range of preservation methods (salted, in brine, dried, smoked) beyond just fresh, chilled, or frozen. Misclassifying these could lead to incorrect duties or non-compliance with veterinary certificates. Another mistake is classifying highly processed or prepared foods derived from these items (e.g., cooked chitterlings) under 0504, when they should go to Chapter 16, 'Preparations of meat, of fish or of crustaceans, molluscs or other aquatic invertebrates.'

Major exporters of guts, bladders, and stomachs are countries with significant livestock industries, such as the USA, Brazil, Germany, and Australia. Key importers include countries with strong culinary traditions involving sausages (e.g., Germany, Poland, France) and pharmaceutical manufacturers globally. Trade is heavily regulated by stringent sanitary certificates, veterinary inspections, and food safety standards due to the biological nature of the products. These regulations can significantly impact market access and overall trade costs, often outweighing standard tariff considerations, although trade agreements can offer duty reductions.

HS code 0504 is a 4-digit heading under Chapter 05 of the Harmonized System. The first 2 digits (05) identify the chapter, and digits 3-4 (04) specify the heading. This code contains multiple 6-digit subheadings for precise product classification.
