Alternative Classifications

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

9027Same rate: 35%

If primarily non-optical thermal measurement

Instruments not using optical radiations (UV, visible, IR) fall under other physical analysis categories.

8419.89.95Higher: 39.2% vs 35%

If classified as industrial furnace or oven

Heating apparatus without analytical functions are under laboratory heating equipment, not analysis instruments.

9031.49Lower: 10% vs 35%

If for measuring or checking other physical/chemical quantities

Chapter note prioritizes 9031 for non-specific measuring instruments over optical thermal analyzers.
