HS Code 19.04 – Prepared foods obtained by swelling or roasting cereals or cereal products (e.g. corn flakes); cereals (other than maize (corn)) in grain form or in the form of flakes or other worked grains (not flour and meal), pre-cooked or otherwise prepared, n.e.c.

HS code 1904 is a 4-digit heading in the Harmonized System that covers: Prepared foods obtained by swelling or roasting cereals or cereal products (e.g. corn flakes); cereals (other than maize (corn)) in grain form or in the form of flakes or other worked grains (not flour and meal), pre-cooked or otherwise prepared, n.e.c.. Heading 1904 encompasses a diverse range of prepared food products derived from cereals and cereal products, characterized by specific preparation methods: swelling or roasting, or being pre-cooked or otherwise prepared (excluding flour and meal). This classification is critical for products like breakfast cereals (e.g., corn flakes, puffed rice, shredded wheat) and various pre-cooked grains such as bulgur wheat, instant oats, or pre-cooked quinoa. The scope of 1904 specifically excludes unprocessed cereals (covered in Chapter 10), flours and meals (Chapter 11), pasta (1902), and bread/pastry (1905), focusing instead on cereals that have undergone significant processing to make them ready for consumption or quick preparation. Key sub-categories include products obtained by swelling or roasting, and cereals (other than maize) that are pre-cooked or otherwise prepared. This classification matters immensely for trade compliance due to varying tariff rates, specific food safety regulations (e.g., for allergens, additives), and labeling requirements that differ from raw agricultural commodities or other processed food categories. Historically, the rise of industrial food processing and the demand for convenience foods, particularly breakfast cereals, propelled the significance of this heading. It sits within Chapter 19, 'Preparations of cereals, flour, starch or milk; pastrycooks' products,' serving as a distinct category for cereal preparations that are neither raw nor traditional baked goods, highlighting the evolution of food technology.

Traders often misclassify products under 1904 by confusing them with less processed cereals. **1006 (Rice)** or **1008 (Other cereals)** are common pitfalls if cereals are merely husked or milled but not 'prepared' by swelling, roasting, or pre-cooking. The critical differentiator is the extent of processing that renders the cereal ready-to-eat or quick-cooking. Similarly, **1104 (Cereal grains otherwise worked)** is often confused if grains are merely rolled or flaked (like rolled oats) but not pre-cooked or roasted. Uncooked pasta products, even if cereal-based, belong to **1902**.

In 2025, the top exporters of HS code 1904 in UN Comtrade data were Germany ($956M, 10% of world exports), Poland ($779M) and the United Kingdom ($677M). World exports came to about $9.1B, 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 1904 in UN Comtrade data were the United States ($1.0B, 11% of world imports), Germany ($744M) and Canada ($660M). World imports came to about $9.2B, 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.
