Silica Quartz Oxidation Boat Holder

A fused silica holder for wafer boats inserted into oxidation furnaces to grow oxide layers on semiconductor wafers. Engineered for thermal stability and minimal contamination in high-temperature environments. Falls under HTS 7017.10.30.00 due to its fused quartz construction and specific semiconductor furnace application.

Alternative Classifications

This product could be classified differently depending on its characteristics or intended use.

7010.90.50Same rate: 37.5%

If in the form of unfinished tubes or rods before final fabrication into holders

Unworked fused quartz products classify under heading 7010, prior to becoming specific lab articles.

7017.90.10Same rate: 37.5%

If constructed from other glass types meeting laboratory glassware criteria

Non-fused quartz lab glassware falls under the residual laboratory glassware provisions.

3824.99Lower: 17.5% vs 37.5%

If chemically prepared as semiconductor processing preparations rather than glassware

Certain prepared chemical articles for semiconductor use may classify under Chapter 38.

Import Tips & Compliance

• Provide engineering drawings showing furnace insertion design and wafer compatibility to support specific HTS classification

• Ensure supplier declarations confirm fused silica material per Chapter 70 fused quartz definition

• Avoid misclassification by distinguishing from general lab ware; include process flow documentation
