3923.10.20.00 - Specially shaped or fitted for the conveyance or packing of semiconductor wafers, masks or reticles of subheadings 3923.10 or 8486.90

This HTS classification, 3923.10.20.00, specifically covers plastic boxes, cases, crates, and similar articles that are designed and manufactured with a special shape or fitting for the secure conveyance or packing of semiconductor wafers, masks, or reticles. The critical distinguishing feature of these articles is their specialized internal configuration, often incorporating precise cutouts, anti-static materials, or cushioning to protect these highly sensitive electronic components during transit and handling.

This category is differentiated from its sibling, 3923.10.90.00 ("Other"), by the explicit mention of their specialized application. While the "Other" category encompasses general-purpose plastic containers for conveyance or packing that do not meet the specific functional requirements of semiconductor component protection, this classification is reserved for items meticulously engineered for that particular purpose. The specialized shaping and fitting are paramount in determining classification under 3923.10.20.00.

As this classification is a leaf node, there are no further subcategories. Therefore, classification within this code relies solely on the precise nature of the article's design and its intended use in safeguarding semiconductor wafers, masks, or reticles, as opposed to general packing materials.
