Dryers, lyophilisation apparatus, freeze drying units and spray dryers, not used for domestic purposes.
Classification of spray dryer under HS 8419.33
Spray dryers are classified under HS code 8419.33. This classification falls under heading 8419, which includes machinery and plant for the treatment of materials by a process involving a change of temperature, such as heating, cooking, roasting, distilling, or drying. Subheading 8419.33 is a specific provision for lyophilization apparatus, freeze-drying units, and spray dryers. A spray dryer operates by atomizing a liquid feed into a hot drying gas medium to rapidly produce a dry powder. This industrial process is distinct from simple centrifugal drying or domestic drying. The classification is determined by the mechanical and thermal principles used to achieve the drying effect in an industrial or laboratory setting. These machines are vital in the food, pharmaceutical, and chemical industries for creating stable, powdered versions of liquid products. The HS code 8419.33 ensures that these complex thermal processing units are distinguished from general-purpose industrial dryers or ovens that do not utilize the atomization and spray-drying technique.

Codes often confused with 8419.33
Common mistake. Spray dryers are often misclassified under HS code 8419.39, which is the residual category for "other" dryers. However, because 8419.33 specifically names spray dryers, it must take precedence according to the rules of specificity. Another common error is classifying them under HS code 8514, which covers industrial or laboratory electric furnaces and ovens. While spray dryers use heat, their primary function is the specialized process of drying through atomization, which is specifically addressed in heading 8419.

How these figures are built
109 countries reported 2025 trade to UN Comtrade in HS 2022, and their own totals are used. Countries marked * did not, so their figures add up what other countries recorded trading with them, and their exports are valued at buyers' CIF prices. 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).
