FAQ for this HTS code.

What is this HTS code?

This is a US Harmonized Tariff Schedule (HTS) code that classifies "Microscopes other than optical microscopes; diffraction apparatus; parts and accessories thereof:". It determines base duty rates for imports; additional duties may apply by country of origin.

Does origin affect duty?

Yes. General and Special rates apply by trade agreement and origin. Additional duties (Section 301, 232, IEEPA) are origin-specific. Use the tariff calculator or resolve API with an origin to see full duty.

How do I compute total duty?

Use our tariff calculator (with HTS and optional origin) or the API endpoint GET /api/v1/tariffs/resolve with hts and origin. The API returns base tariffs and additional measures separately; sum as needed for your use case.
