HS Code 8419.33 – Dryers; lyophilisation apparatus, freeze drying units and spray dryers, not used for domestic purposes
HS code 8419.33 is the 6-digit subheading for dryers, lyophilisation apparatus, freeze drying units and spray dryers, not used for domestic purposes. It is used for pharmaceutical freeze dryers, industrial lyophilizers, laboratory freeze drying units, food spray dryers and chemical spray dryers.
What HS 8419.33 covers
This HS code covers sophisticated industrial drying equipment, specifically lyophilizers (freeze dryers) and spray dryers, which are vital for preserving sensitive materials and creating fine powders in various industries. Lyophilization is crucial for pharmaceuticals, biotechnology, and food processing, enabling long-term storage of vaccines, enzymes, and instant coffee. Spray dryers are extensively used in dairy, chemical, and ceramic industries to convert liquid feeds into dry powders. International trade is driven by the demand for high-quality, stable products and efficient processing. Importers include pharmaceutical companies, food processors, chemical manufacturers, and research labs. Exporters are typically specialized engineering firms. Key trade considerations involve capacity, energy efficiency, product integrity, and compliance with industry-specific regulations (e.g., GMP for pharma).

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).
