The Section 301 tariffs on goods from China and other countries have reshaped global supply chains. For importers, these duties can significantly impact product margins and pricing strategies. Yet, proactive companies are finding legal, creative ways to mitigate the impact through tariff exclusions, product modifications, and re-engineering—all while staying compliant with U.S. Customs and Border Protection (CBP) regulations.

This article explores how trade professionals can apply these strategies to manage 301 duty exposure responsibly and effectively.

Understanding Section 301 Duties

Section 301 duties are additional tariffs imposed by the United States under the Trade Act of 1974. They target specific countries and product categories based on findings of unfair trade practices, intellectual property violations, or other policy concerns.

Since 2018, these duties have affected thousands of HTS classifications, ranging from industrial machinery to consumer electronics. Importers face additional tariffs of 7.5% to 25%, depending on the product’s classification.

Strategy 1: Using Tariff Exclusions

When the U.S. Trade Representative (USTR) announces exclusion opportunities, importers can petition for temporary relief from 301 duties. Even though many rounds have expired, reactivations and new reviews occur periodically.

Key steps for leveraging exclusions include:

• Monitor the Federal Register for reinstatement notices and deadlines.
• Document eligibility with proof of product equivalence and sourcing history.
• File timely requests with comprehensive technical descriptions.
• Coordinate with suppliers to ensure consistent part numbers and specifications.

Even after an exclusion expires, companies may still seek retroactive refunds for entries filed during the covered period if they meet all requirements.

Strategy 2: Product Modifications and Re-engineering

Re-engineering products can sometimes move them into a different Harmonized Tariff Schedule (HTS) classification not subject to 301 duties. This is a form of tariff engineering, which is legal when the physical characteristics of the imported product support the declared classification.

Examples include:

• Material substitution: Using non-Chinese components or alternate materials.
• Functional redesign: Simplifying or separating product components so that imports reflect distinct subassemblies.
• Firmware or software adjustments: Importing devices without embedded programs when the classification changes based on programming state.
• Packaging or assembly modifications: Altering the imported form without misrepresenting its true nature.

Every modification must reflect the commercial reality at the time of importation and be supported by clear documentation, engineering drawings, and testing data.

Strategy 3: Country-of-Origin Shifts

In some cases, companies can shift final assembly or substantial transformation to countries not covered by Section 301 duties. However, this strategy requires careful analysis of origin rules, as minor processing in a third country will not change the product’s origin under CBP standards.

Compliance teams should verify transformation steps using rulings, lab reports, and bill of materials documentation before declaring a new origin.

Avoiding Red Flags and Compliance Risks

Customs authorities closely monitor changes made solely for tariff avoidance. To stay compliant:

• Never obscure the true origin or actual manufacturing process.
• Maintain detailed records of design rationale and engineering decisions.
• Confirm that all import documentation, including invoices and HTS declarations, matches the product’s imported condition.
• Consider obtaining a binding ruling from CBP to validate new classifications or origin determinations.
