Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If principally for agricultural machinery integration
Instruments for machines in Section XVI classify there per Chapter 90 note 1(g).
If functioning primarily as a thermometer rather than hygrometer
Heading prioritizes principal function; thermometer-only instruments go to 9025.19.
If sold as part of automated environmental control machine
Complete machines with control functions classify under 8479, not as separate instruments.

Import Tips & Compliance
• Certify agricultural end-use to support classification; industrial process use may differ
• Avoid bundling with data loggers to maintain non-recording status
• Check for exclusion under technical textile supports if incorporating elastic fabrics (Chapter 90 note 1(b))
