8485.30.00.00 - By plaster, cement, ceramics or glass deposit

HTS Code 8485.30.00.00 encompasses machines for additive manufacturing that build objects through the deposition of plaster, cement, ceramics, or glass. These machines operate by selectively applying or solidifying these non-metallic, inorganic materials layer by layer to create a three-dimensional form. Examples include 3D printers utilizing ceramic pastes, cementitious mixtures for construction, or glass powders that are then sintered.

This category is distinguished from its siblings by the specific materials used in the deposition process. HTS 8485.10.01.00 covers machines that deposit metal, while 8485.20.00.00 applies to those depositing plastics or rubber. The "Other" category, 8485.80.00.00, is for additive manufacturing machines that do not fall into the defined material categories of metal, plastic, rubber, plaster, cement, ceramics, or glass, or that utilize a combination of these distinct material types in a manner not covered by the more specific headings.

As a leaf node, 8485.30.00.00 does not have further subcategories. Classification within this code relies on the definitive identification of the primary deposition material as plaster, cement, ceramics, or glass. Therefore, the critical distinguishing factor for correct classification under this heading is the material composition being processed and deposited by the additive manufacturing machinery.
