Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If primarily a processor or controller
Integrated circuits acting as processors or controllers for specific functions fall under 8542.31, not dedicated active filters.
If general other ICs without specific filter function
Broader 8542.39 covers other ICs; active filter specificity requires proof of filtering characteristics.
If sold as discrete assembled modules rather than monolithic IC
Assembled electronic modules or parts not qualifying as integrated circuits go to 8543.90.

Import Tips & Compliance
• Verify the IC datasheet confirms active filtering functionality with internal op-amps to meet HTS 8542.39.00.20 classification
• Include manufacturer specifications and test reports in documentation to prove it's not a general-purpose amplifier or processor
• Avoid misclassification as discrete components; ensure packaging labels it as an integrated circuit
