U.S. imports of lyophilization apparatus, freeze-drying units, and spray dryers (HS 841933) totaled $1.0M in April 2026, traded with 16 countries.
Importers of Lyophilization Apparatus, Freeze-Drying Units, and Spray Dryers paid $86K in duties in April 2026 — an effective duty rate of 12% on $732K in dutiable value, based on actual customs collections rather than the published tariff schedule. Lyophilization Apparatus, Freeze-Drying Units, and Spray Dryers imports of $1.0M in April 2026 ran 14% above the year-to-date monthly average of $880K.
Last updated: April 2026 dataFreeze-drying (lyophilization) and spray-drying equipment occupies a specialized niche across pharmaceutical manufacturing, food processing, and agricultural applications. The US tariff schedule divides this heading between agricultural-use apparatus (8419331000) and all other uses (8419335000), so a freeze-dryer destined for a pharma API plant classifies differently than one sold to a coffee or fruit processor. Lyophilizers for pharmaceutical use are capital-intensive, highly engineered systems often sourced from European and Japanese manufacturers, and their classification can intersect with FDA facility registration requirements when the equipment is integral to drug production.

The agricultural subheading applies to apparatus principally designed and used for drying agricultural products such as grains, herbs, or food ingredients. Equipment designed for pharmaceutical, chemical, or industrial applications — even if it could theoretically process food — is classified under 8419335000. The importer's purchase order, technical specifications, and end-use declaration are key supporting documents.
Not necessarily. A spray dryer for infant formula or other food ingredients may qualify under the agricultural subheading (8419331000), while one dedicated to pharmaceutical excipient or API production would fall under 8419335000. The intended end-use at the time of importation governs, and documentation of the buyer's production process strengthens the classification position.
