8514.39.10.00 - Of a kind used solely or principally for the manufacture of printed circuits or printed circuit assemblies

This HTS classification, 8514.39.10.00, specifically designates industrial or laboratory furnaces and ovens that are primarily or exclusively employed in the manufacturing processes of printed circuits or printed circuit assemblies. This includes equipment used for various heat treatment stages critical to PCB fabrication, such as curing solder paste, reflow soldering, or firing dielectric layers. The defining characteristic for classification under this subheading is the intended end-use in the specialized production of these electronic components.

This subheading is distinguished from its sibling, 8514.39.90.00, which covers "Other" furnaces and ovens not meeting the specific manufacturing purpose outlined here. While both fall under the broader category of "Other" furnaces and ovens, 8514.39.10.00 is reserved for equipment with a singular or principal application in the printed circuit industry. Therefore, general-purpose ovens or those used for a wider range of material heat treatments would typically be classified under the sibling category.

As a leaf node in the HTS database, this category does not have further subdivisions. Classification into 8514.39.10.00 relies on confirming the primary or sole use of the furnace or oven for the manufacture of printed circuits or printed circuit assemblies, as opposed to other industrial heating applications.
