8422.30.91.50 - Vacuum or gas packaging

This HTS category, 8422.30.91.50, specifically encompasses machinery designed for vacuum or gas packaging. These machines are utilized to remove air from a package and then seal it, or to displace the internal atmosphere with a specific gas mixture (such as nitrogen or carbon dioxide) before sealing. This process is crucial for extending the shelf life of perishable goods, protecting sensitive items from oxidation or spoilage, and maintaining product integrity during transit and storage. Examples include vacuum sealers for food products, modified atmosphere packaging (MAP) machines for fresh produce, and nitrogen flushing machines for electronics.

The distinction between this category and its sibling, 8422.30.91.60 "Other," lies in the specific function of vacuum or gas displacement. While the sibling category covers a broader range of "other" machines that perform capping, lidding, sealing, or closing operations, this node is precisely defined by its ability to create a vacuum or modify the atmospheric composition within the packaging. It does not include machines that solely perform sealing without prior vacuuming or gas insertion, nor those focused on other aspects like capping or labeling.

As this is a leaf node within the HTS structure, there are no further subcategories. Therefore, the focus for classification purposes remains on verifying that the machinery's primary function is indeed vacuum or gas packaging, as opposed to other types of sealing or container manipulation covered by adjacent HTS codes.
