4411.12.60.00 - Not surface covered (except for oil treatment) 🖩

This HTS category, 4411.12.60.00, specifically covers medium density fiberboard (MDF) with a thickness not exceeding 5 mm, which is neither surface covered nor treated with oil. The defining characteristic here is the absence of any surface treatments, such as laminates, veneers, or painting, beyond simple oil treatment, which is also excluded from this specific subcategory. This designation is crucial for distinguishing it from other forms of processed wood fiber.

The primary sibling category to consider is 4411.12.90, which encompasses "Other" medium density fiberboards of a thickness not exceeding 5 mm. This implies that 4411.12.60.00 represents a very specific subset within this thickness range, differentiated by the lack of surface treatments. Therefore, any MDF within the 5mm thickness limit that *does* have surface treatments, such as printing, coating, or lamination, would fall under the "Other" category (4411.12.90) and not this one.

As this is a leaf node in the HTS classification structure, there are no further subdivisions within 4411.12.60.00. The classification is final at this level, emphasizing the precise physical state of the fiberboard: medium density, a thickness of 5 mm or less, and importantly, an untreated surface (excluding oil treatment). This granular detail ensures accurate tariff application for these specific types of fiberboard panels.
