HS Code for Freeze dryer

A freeze dryer, or lyophilization apparatus, is classified under HS code 8419.33. This classification is determined by the functional nature of the machine, which uses a process of sublimation to remove moisture from products. Heading 8419 covers machinery and plant equipment for the treatment of materials by a process involving a change of temperature, such as heating or drying. Within this heading, subheading 8419.33 is specifically dedicated to lyophilization apparatus and freeze-drying units. This code is applicable to industrial and laboratory-grade equipment used in pharmaceutical, food processing, and scientific research sectors. The classification relies on the fact that the primary function is drying through the specific technical method of freezing the material and then reducing the surrounding pressure to allow frozen water to sublimate.

Products Included

Common Misclassification

Freeze dryers are often misclassified under HS code 8418, which covers refrigerators and freezers. While freeze dryers do incorporate refrigeration components to freeze the product, their primary purpose is drying, not just cooling or storage, which places them in 8419. Another common error is using 8419.39, which is the residual category for "other" dryers. Because 8419.33 is a specific 6-digit subheading for lyophilization, it takes precedence over the general category. Furthermore, small domestic units might be confused with 8509 (electro-mechanical domestic appliances), but if the unit performs true lyophilization, 8419.33 remains the most accurate technical classification.

FAQ

What is the HS code for freeze dryer?

The international HS code for a freeze dryer (lyophilization apparatus) is 8419.33.

Does this code apply to both food and medical freeze dryers?

Yes, HS code 8419.33 applies to freeze-drying units regardless of whether they are used for food preservation, pharmaceutical manufacturing, or laboratory research, provided they are not for domestic use.
