What else affects this line Outside Portigo's full-coverage set
This product's HTS chapter is not one of Portigo's eight fully-curated chapters. The base
(MFN) rate and any Section 301 or 232 overlays shown are real, but this chapter has not had
the trade-SME review the core chapters receive, AD/CVD orders are not flagged ,
and overlay coverage may be incomplete. Treat the total as an estimate, not a complete landed
cost, and verify with a licensed customs broker.
You may be owed a CAPE refund
Imports from this origin were subject to IEEPA emergency duties between 2025-02-04 and 2026-02-20.
The Supreme Court ruled IEEPA does not authorize tariffs, and CBP's CAPE process can refund
IEEPA duties paid on past entries. This does not affect Section 301, 232, 122, or fees.
