The August 24 Learning Resources motion in the Section 301 forced-labor tariff lawsuit puts USTR's 10 percent and 12.5 percent rates under a separate appropriateness test. An import compliance manager should keep current duty treatment as the model's base case while tracking the rate evidence the government cites on September 4.

The August 24 Rule 56.1 motion in the Section 301 forced-labor tariff lawsuit isolates one question. What connects USTR's 10 percent and 12.5 percent duties to the statutory objective of eliminating each investigated practice?
Section 301(b) requires more than a finding that an unreasonable or discriminatory practice burdens U.S. commerce. USTR must also determine that action by the United States is appropriate, then choose appropriate and feasible action to obtain elimination of the practice. Section 304 requires USTR to determine what action, if any, should be taken and publish the factual basis for that decision.
The plaintiffs present appropriate action as a third and independent requirement. Their theory would permit scrutiny of the chosen tariff rate even if other parts of USTR's decision survived review. The court has not adopted that theory. The August 24 filing is an advocacy document, and none of its factual or legal claims is a holding.
For an import compliance manager, the filing adds a rate-nexus field to the duty-contingency model. That field keeps the rate evidence separate from the rest of the case, avoiding one undifferentiated probability across the entire lawsuit. Current duty treatment remains the base case.
Two appropriateness decisions sit inside Section 301(b)
The relevant statutory sentence contains two decisions. USTR first determines whether action by the United States is appropriate. Once that condition is met, the agency chooses appropriate and feasible action directed at obtaining elimination of the investigated act, policy, or practice. The August 24 motion relies on this sequence to argue that the second decision reaches the design of the remedy, including its rate.
The Federal Circuit's 2025 HMTX decision supplies the most important language for that argument. The court described appropriate as a broad term anchored to a specific purpose. A discretionary Section 301 action must be capable of ending or reversing the investigated conduct.
HMTX addressed USTR's Section 307 authority to modify an existing discretionary Section 301 action, not the validity of an initial action like the forced-labor tariffs. It nevertheless gives the government substantial room. The Federal Circuit held that USTR could increase the List 3 and List 4A China tariffs after determining that China's response had made the earlier action insufficient. The opinion treated appropriateness as a judgment for USTR, subject to presidential direction, and imposed no mathematical proportionality requirement on a discretionary action.
The government's September 4 response will show how it reads those two features of HMTX. The statutory objective constrains the action, while USTR retains judgment over the means. The factual bridge between them is the contested ground.
At memorandum pages 29 to 31, the plaintiffs argue as a matter of statutory authority that naming a remedy does not supply the facts showing why it can end or reverse the targeted conduct. At pages 44 to 47, they recast the rate-specific challenge under the APA, contending that USTR did not adequately explain why the 10 percent and 12.5 percent baselines would obtain the statutory result.
The court could reject that construction, find USTR's explanation sufficient, or decide that the statute leaves the rate judgment largely to the agency. The filing still separates authority to use a tariff from the adequacy of the selected rate. That distinction belongs in the contingency model now.
The final action did address the choice between its two target levels.
Seventeen economies receive a flat 10 percent Section 301 duty. Thirty-eight receive a flat 12.5 percent duty. Five use a duty-gap formula. For the European Union and Taiwan, the Section 301 increment brings the combined MFN and Section 301 rate to 10 percent. For Japan, South Korea, and Switzerland, it brings the combined rate to 12.5 percent. The Section 301 increment is zero when the MFN rate already meets or exceeds the target. Product exclusions and other scope rules remain separate checks.
USTR answered the rate comments by pointing to measures and commitments announced after the proposal, then concluded that the two levels and their 2.5 percentage point difference were significant enough to spur action. The lower band recognized specified measures or commitments.
The plaintiffs dispute the sufficiency of that explanation. Their motion characterizes it as generalized and argues that USTR did not adequately link either baseline to the result required by Section 301(b).
The parties have put the path from the chosen rate to the statutory objective at issue. They disagree over whether USTR's use of the words appropriate and elimination is backed by enough record reasoning. The government's response can point to the explanation at 91 Fed. Reg. 47,329 to 47,330, additional administrative-record citations, HMTX's treatment of agency discretion, or a combination of those sources. As of August 25, ECF No. 17 supplies a generic master answer and anticipated defenses, but expressly reserves fuller development for dispositive briefing. The public docket therefore has the plaintiffs' full Rule 56.1 presentation and USTR's published explanation, but not the defendants' consolidated merits response due September 4.
Put the litigation beside the duty calculation
The operative tariff calculation should remain the model's base case. Filing a Rule 56.1 motion does not alter the final action.
For a flat-rate economy, the model continues adding the full Section 301 rate to the otherwise applicable tariff stack, subject to exemptions and implementation terms in the final action. For a duty-gap economy, use the applicable target:
The target is 10 percent or 12.5 percent under the final action. A hypothetical move between the two flat bands changes exposure by 2.5 percentage points. Under the duty-gap structure, the effect depends on the product's MFN rate and may be smaller or zero.
The litigation field belongs beside that calculation. It records why the rate is under review, the status of the evidence, and the event authorized to change the operating assumption.

The tags keep a litigation claim from silently becoming an operating instruction. O controls the live duty calculation. A identifies an argument that could affect the model later. A holding becomes H only after the court decides the issue. S fixes the next scheduled evidence update.
For a flat-rate product, forecast entered value multiplied by the relevant rate difference gives the gross exposure range. For a duty-gap product, use the actual MFN rate at the tariff-line level. Exempt merchandise stays outside the incremental scenario to the extent provided by the operative action.
The control card keeps a litigation scenario out of current entry calculations until an operative event makes it relevant. It also brings the dispute into landed cost, where a narrative legal note is easy to miss.
September 4 will show how the government defends the number
The defendants' consolidated response is due September 4 under the court's scheduling order. That filing is the next scheduled update to the rate contingency.
The key model input will be any record citation explaining why the selected levels were expected to change the targeted conduct. The final notice already says that the rates and the 2.5 percentage point difference were significant enough to spur action. The response may identify the record material behind that judgment, explain how the lower and higher bands reflect different responses, and show how the duty-gap formulas serve the same statutory objective.
HMTX supports USTR's discretion while giving the plaintiffs language that ties appropriateness to an action capable of ending or reversing the conduct. The September 4 brief can connect those positions by identifying what USTR knew about the rate's expected operation when it acted and where that reasoning appears in the record.
When the September 4 brief arrives, add the government's citations to the rate-nexus field. The operative rate remains O unless a later event carries legal or entry effect. The model then recognizes the new litigation predicate without changing the duty treatment currently in force.
