5911.40.01.00 - Filtering or straining cloth of a kind used in oil presses or the like, including that of human hair

This HTS classification, 5911.40.01.00, specifically covers filtering or straining cloth intended for use in oil presses or similar industrial applications. The defining characteristic of these textiles is their function in separating solids from liquids or gases, particularly in processes involving high pressure or the extraction of oils. Notably, this category explicitly includes such cloths even if they are manufactured from human hair, a material chosen for its specific filtering properties in certain contexts.

While other categories within Chapter 59.11 address textiles for technical uses, 5911.40.01.00 is distinct in its focus on filtration and straining within oil extraction and analogous processes. For instance, it differs from 5911.10 which pertains to fabrics for card clothing and spindle coverings, and from 5911.20 which is specifically for bolting cloth used in sieving grains. Furthermore, it is separate from the broad category for endless felts used in papermaking machinery (5911.31 and 5911.32) and the general "other" category (5911.90.00).

As a leaf node in the HTS database, this classification does not have further subdivisions. Therefore, the primary classification criteria will revolve around the physical characteristics of the fabric, its mesh size or porosity, and its intended end-use as a filtering or straining material within an oil press or comparable industrial setup. Evidence of its application in such machinery or its suitability for such a purpose is key to its correct classification under this specific code.
