Alternative Classifications

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

8471.49.00.00Lower: 32.5% vs 36.4%

If imported as integral part of a complete crystal grower machine

Assembled semiconductor manufacturing machines including cooling components fall under heading 8471 as automatic data processing or production machinery.

8419.89.95Higher: 39.2% vs 36.4%

If for industrial use outside semiconductor wafer processing

Heat exchangers for other industrial machinery storage units are classified in 8419 if not specifically for air conditioning temperature/humidity control.

9032.89.60Higher: 36.7% vs 36.4%

If primarily for testing semiconductor wafers rather than processing

Testing apparatus for semiconductor devices, including temperature control units, moves to Chapter 90 per statistical notes.
