HS-6 · Subheading
841933
Dryers; lyophilisation apparatus, freeze drying units and spray dryers, not used for domestic purposes
Heading 8419 — Machinery, plant (not domestic), or laboratory equipment; electrically heated or not, (excluding items in 85.14) for the treatment of materials by a process involving change of temperature; including instantaneous or non electric storage water heaters
Chapter 84: Nuclear reactors, boilers, machinery
Plain-language overview
Use HS-6 841933 when importing or exporting industrial dryers, specifically lyophilisation apparatus and freeze-drying units. For example, if you're shipping a freeze dryer used in a pharmaceutical lab, this code applies.
This code is distinct from HS-6 841931, which covers spray dryers. While both are used for drying processes, 841933 specifically targets equipment that uses lyophilisation, a method crucial for preserving sensitive materials.
Items classified under 841933 include industrial-grade freeze-drying machines that remove moisture from products like food, pharmaceuticals, and biological samples by freezing them and then reducing the surrounding pressure.
When dealing with these units, ensure they are not designed for domestic use, as that would shift classification to a different heading. Always check the specifications to confirm their industrial application.
