§ FAQFrequently asked questions

What is the US import duty for HTS 2903.77.00?
HTS 2903.77.00 (Other, perhalogenated only with fluorine and chlorine) has a general (MFN) column rate of 3.7%. No Chapter 99 overlays are currently linked to this line. Final duty is determined by CBP at entry.
Does Section 301 or IEEPA tariff apply to HTS 2903.77.00?
No Chapter 99 overlay is linked to this line in our current snapshot. That means no Section 301, IEEPA, or reciprocal additional duty is mechanically attached. Always double-check against the latest Federal Register for proclamations that may not yet be reflected in the HTS export.
Could HTS 2903.77.00 be subject to antidumping / countervailing duty (AD/CVD) orders?
Organic chemicals (Chapter 29) see a high volume of AD/CVD orders on specific products and countries. Duty does not evaluate AD/CVD automatically — check the DOC AD/CVD dashboard and CBP messages for your specific product + origin before quoting a landed cost.
How do I compare duty from different countries for HTS 2903.77.00?
Use the origin compare view to evaluate this HS code against alternative countries. The calculator applies each country-specific Chapter 99 overlay and the appropriate column rate.
Is this the binding duty determination?
No. This page is a reference built on USITC + Federal Register open data. The binding classification and duty amount is determined by CBP at entry. AD/CVD and product-specific exclusions require separate review.
