Section 301 Retroactive Refund Options

Section 301 retroactive refunds come through three pathways: (1) exclusion approvals (refund duty paid during active exclusion period), (2) protest filing under 19 USC § 1514 within 180 days of liquidation challenging Section 301 application, and (3) reliquidation under § 1520. None covers the full Section 301 period; specific eligibility is narrow.

This guide covers Section 301 Retroactive Refund Options. The Section 301 program targets China-origin goods at rates of 7.5-25% across Lists 1-4A, with periodic exclusion processes.

For SMB importers paying Section 301, mitigation options include reclassification, supply-chain shifts, USMCA qualification on Mexican production, and exclusion requests where available.

Exclusion-based refunds

When USTR approves an exclusion, importers can claim retroactive refund of Section 301 duty paid during the exclusion’s active period. Filing through CBP within applicable deadlines.

Protest-based challenges

For entries where Section 301 was incorrectly applied (wrong country of origin, wrong HS classification, etc.), protest filing within 180 days of liquidation provides a recovery path.

Reliquidation under § 1520

For specific cases of CBP error or clerical mistake. Narrow eligibility; rarely successful for substantive Section 301 disputes.

What is NOT refundable

Section 301 duty correctly paid on covered Chinese-origin goods, where no exclusion was granted, is not refundable. The Supreme Court IEEPA ruling did not affect Section 301.

Frequently asked questions

Does Section 301 still apply in 2026?

Yes. Section 301 has no statutory expiration and continues in force. The current administration has indicated periodic adjustments but not termination.

Can I file a Section 301 exclusion request?

Periodic exclusion processes have run since 2018; the current process status varies. We track active and pending exclusion windows.

How does Section 301 stack with Section 122?

Both apply to China-origin goods. Section 122 (15%) plus Section 301 (List-specific 7.5-25%) plus base MFN. Effective rates often 22-42%.

Can shifting from China to Vietnam or Mexico help?

Yes – provided substantial transformation actually occurs in the new origin country. Misclaimed origin exposes you to retroactive Section 301 plus Section 1592 penalties.

How do you help with Section 301 work?

We run classification audits, supply-chain shift feasibility analyses, USMCA qualification reviews, and exclusion requests. Engagements typically $5,000-$15,000 fixed-fee per project.
