Section 301: China vs Vietnam Origin – Compliance Reality

Goods substantially transformed in Vietnam acquire Vietnam origin and avoid Section 301. Substantial transformation requires more than simple assembly, packaging, or labeling – it requires manufacturing that creates a new article with a distinct character. Misclaimed Vietnam origin where transformation does not actually occur exposes the importer to retroactive Section 301 plus penalties.

This guide covers Section 301: China vs Vietnam Origin – Compliance Reality. 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.

Substantial transformation test

CBP applies the substantial transformation test for Section 301 purposes. The test asks whether processing creates a new and different article from the imported components – change in name, character, or use.

What does NOT qualify as substantial transformation

Simple assembly of imported components, repackaging, relabeling, or testing/inspection alone do not constitute substantial transformation.

Documentation supporting Vietnam origin

Manufacturing process descriptions, BOM analysis showing Chinese vs. Vietnamese inputs, supplier affidavits from Vietnamese manufacturers, factory inspection reports.

CBP trans-shipment scrutiny

CBP enforcement on Section 301 trans-shipment via Vietnam has intensified. Misclaimed origin can result in retroactive Section 301 application plus civil penalties under 19 U.S.C. § 1592.

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.
