Section 301 China duties are drawback-eligible. Here's how to recover them.

Section 301 China duties are not a special, non-recoverable tariff bucket. They are additional customs duties imposed under federal law, reported through Chapter 99 of the HTSUS, and CBP has expressly confirmed that they may be claimed in drawback.

That matters because the dollar amounts are often much larger than ordinary Column 1 duties. A 7.5%, 25%, 50%, or 100% Chapter 99 line can sit on the same entry as a modest regular duty rate. If the exported or destroyed merchandise qualifies for drawback, the Section 301 portion should be tested and claimed with the rest of the eligible duties.

Where Section 301 China duties sit in the tariff schedule

Section 301 is the trade-remedy authority in 19 USC § 2411. It authorizes USTR, after the required determinations, to impose duties or other import restrictions on goods of the foreign country. For China-origin goods covered by the technology-transfer investigation, those additional duties are implemented in HTSUS Chapter 99, Subchapter III, alongside the ordinary Chapter 1–97 classification for the product.

As of this writing, USTR continues to maintain the China Section 301 action. USTR’s Section 301 page still lists the China technology-transfer investigation, initiated August 24, 2017, and the current HTSUS search results include the China Section 301 Chapter 99 series, including 9903.88 headings and newer 9903.91 headings added through later modifications.

Current exclusion status should also be checked before calculating duty paid. USTR extended 178 current exclusions through 11:59 p.m. Eastern time on November 9, 2026, covering exclusions under 9903.88.69 and 9903.88.70. Excluded goods may have no Section 301 duty to recover for the excluded entries.

Why the duties are drawback-eligible

The basic drawback statute, 19 USC § 1313, allows drawback when qualifying imported merchandise, substitute merchandise, or manufactured articles are exported or destroyed. The modernized drawback regulations state that drawback is allowable on duties, taxes, and fees paid on imported merchandise that were imposed under federal law upon entry or importation, unless a specific exclusion applies.

Section 301 duties fit inside that rule. They are duties imposed under federal law upon importation. CBP’s trade-remedy drawback guidance is direct: Section 301 duties are eligible for duty drawback. CBP’s later CSMS guidance also tells filers how to file claims involving Section 301 duties: provide both the Chapter 99 tariff number and the associated Chapter 1–97 tariff number on all claims.

The practical result is straightforward: if a claim qualifies under a drawback provision, the Section 301 duties paid on the designated import line should generally be part of the recoverable duty pool. That includes direct-identification and substitution manufacturing drawback, unused merchandise drawback, rejected merchandise drawback, and export or destruction scenarios that otherwise meet the statutory and regulatory requirements.

The 99% factor: “eligible” does not mean 100% refund

For most drawback claims, the maximum refund is 99% of the eligible duties, taxes, and fees. CBP retains 1%. That 99% factor applies to the Section 301 portion just as it applies to ordinary duties, subject to the claim type and any applicable “lesser of” limitations.

Example: if an importer paid $250,000 in Section 301 duties on eligible import lines and later supports a qualifying export claim for the full eligible quantity, the Section 301 component of the estimated drawback is generally $247,500 before any claim-specific caps, apportionment, reductions, or CBP adjustments.

Why Section 301 is so often missed

The Chapter 99 line is not carried into the drawback model

Many drawback models are built around the Chapter 1–97 HTSUS classification. That is necessary, but not sufficient for Section 301 recovery. The Section 301 duty is usually reported on a separate Chapter 99 line. If the drawback data pull drops Chapter 99, the claim may recover ordinary duty while leaving the largest duty component behind.

Entry data and export data do not join cleanly

Section 301 recovery depends on the same core drawback proof as any other claim: import entry data, duty paid, quantity, value, HTSUS, product identifiers, transfers, manufacturing records if applicable, and export or destruction evidence. If SKU, part number, lot, or bill-of-material data is inconsistent, the Section 301 line becomes difficult to allocate and support.

Teams assume “trade remedy” means “not eligible”

This is the most common conceptual error. Some trade remedies are not drawback-eligible. Section 301 China duties are different. CBP has confirmed eligibility, and the Part 190 exclusion for antidumping and countervailing duties does not apply to Section 301 duties.

Exclusions and duty changes create noise

A China-origin product may move through different Section 301 rates or exclusions over time. Some entries may carry a 9903.88 duty line; others may be excluded under 9903.88.69 or 9903.88.70; newer strategic-sector goods may involve 9903.91 provisions. If the drawback process does not capture duty actually paid at the entry-line level, estimates will be wrong.

How to recover Section 301 duties

• Start with paid-entry data. Pull ACE entry summaries at the line level, including Chapter 99 HTSUS, Chapter 1–97 HTSUS, entered value, quantity, duty paid, MPF, HMF, liquidation status, and any post-entry changes.
• Identify the Section 301 lines. Flag China-origin entries with 9903.88 or 9903.91 duty provisions, then separate dutiable lines from exclusion lines such as 9903.88.69 and 9903.88.70.
• Match the right drawback program. Use manufacturing drawback where imported or substituted merchandise is used to produce exported articles; unused merchandise drawback where imported or substituted goods are exported or destroyed unused; and rejected merchandise drawback for qualifying nonconforming, defective, shipped-without-consent, or qualifying retail-returned merchandise.
• Preserve the Chapter 99-to-Chapter 1–97 relationship. CBP requires both HTSUS numbers on claims involving Section 301 duties. The drawback file should show which Chapter 99 duty line belongs to which underlying product line.
• Calculate at the line level. Apply the 99% factor to the eligible Section 301 duty paid, then apply any substitution, comparative-value, USMCA, destruction-value, or other claim-specific limitation.
• Support the export or destruction. Maintain export bills of lading, commercial invoices, AES or other export evidence, destruction approvals and certificates where applicable, inventory records, manufacturing records, and transfer records.
• File, monitor, and reconcile. Submit the drawback claim in ACE, respond to CBP requests, and reconcile the estimate against liquidation, protests, refunds, exclusions, PSCs, and prior disclosures that may affect duty paid.

A simple internal test

Ask four questions for each China-origin import line:

• Did the entry actually pay Section 301 duties under a Chapter 99 provision?
• Was the same merchandise, a valid substitute, or an article made from it exported or destroyed within the applicable drawback timeframe?
• Can the company connect import, inventory, production, transfer, and export data with ordinary business records?
• Has the claim model included both the Chapter 99 duty and the underlying Chapter 1–97 HTSUS line?

If the answer to those questions is yes, the Section 301 amount should not be treated as an afterthought. It should be part of the drawback recovery calculation.

One final caution: drawback calculations are estimates until CBP acts. Accelerated payment, if available, is not liquidation of the drawback entry. Final refunds are set by CBP at liquidation and can change based on eligibility review, duty-paid status, exclusions, protests, amendments, or other entry activity.
