South Korea Steel Plate Dumping Duties Finalized

The U.S. Department of Commerce has determined that certain steel plate products from South Korea were sold in the U.S. below fair market value during February 2024-January 2025, resulting in new antidumping duty rates that will increase costs for importers of Korean cut-to-length carbon-quality steel plate.

What Changed in This Administrative Review?

The Department of Commerce completed its annual administrative review of antidumping duties on cut-to-length carbon-quality steel plate (CTL plate) from the Republic of Korea, covering the period from February 1, 2024, through January 31, 2025. The final results confirm that Korean producers and exporters sold these products in the United States at prices below normal value—a practice known as "dumping" that gives foreign manufacturers an unfair competitive advantage.

This review determines the specific antidumping duty rates that will apply to imports from reviewed Korean companies for the next year. These rates are in addition to standard customs duties and are assessed on a company-specific basis.

Key Finding: Commerce found evidence of below-market pricing during the review period, which means antidumping duties will continue to apply—and potentially increase for some importers compared to previous rates.

Which Products Are Subject to These Duties?

Product Scope

The antidumping order covers cut-to-length carbon-quality steel plate—flat-rolled steel products that are:

• Material: Non-alloy or low-alloy steel (carbon content typically under 2%)
• Form: Cut to specific lengths (not coiled)
• Thickness: Typically 0.375 inches (9.5mm) or greater
• Width: 10 inches (254mm) or greater
• Common uses: Construction equipment, bridges, industrial machinery, shipbuilding, storage tanks, rail cars, and heavy equipment manufacturing

What's Included

• Hot-rolled carbon steel plate
• Normalized steel plate
• Heat-treated plate products
• Plate cut to length from coil
• Both prime and non-prime products

What's Excluded

• Stainless steel plate (covered under separate orders)
• Clad plate products
• Plate with decorative coatings
• Cut-to-length alloy steel plate (different product classification)

HS Codes: Products typically enter under HTS codes 7208.40.3030, 7208.40.3060, 7208.51.0030, 7208.51.0045, 7208.51.0060, 7208.52.0000, 7211.13.0000, 7211.14.0030, 7211.14.0045, 7225.40.1110, 7225.40.1180, 7225.40.3005, 7225.40.3050, and others. However, HS classification alone does not determine coverage—the product's physical characteristics control.

Who Is Affected by These Final Results?

Mandatory Respondents

Commerce selected specific Korean producers/exporters for individual examination during this review. These companies receive their own calculated dumping margins based on their actual sales data.

All Other Korean Producers

Companies not individually reviewed receive a weighted-average duty rate based on the mandatory respondents' margins.

U.S. Importers

This matters most to you: If you imported CTL plate from Korea between February 2024 and January 2025, you will receive instructions from U.S. Customs and Border Protection (CBP) regarding assessment of final antidumping duties. If you currently import from Korean suppliers, these rates will apply to future shipments.

Why This Administrative Review Matters to Small Importers

Administrative reviews happen annually for products under antidumping orders. While the order itself (established years earlier) remains in place, these reviews update the duty rates based on current market conditions and company behavior.

Three critical impacts:

1. Retroactive Assessment: Duties on entries made during February 2024-January 2025 will be finalized at the rates determined in this review. If you posted cash deposits at the old rate, you may owe additional duties—or receive a refund if the new rate is lower.

2. Going-Forward Rates: The new rates become the cash deposit rates for all future imports from reviewed Korean companies until the next review is completed.

3. Supply Chain Costs: Higher duties may make Korean steel plate less competitive compared to domestic sources or imports from countries without antidumping orders. This affects your purchasing decisions and project budgets.

Real-World Example

A U.S. construction equipment manufacturer importing 500 tons of CTL plate annually from Korea at $800/ton pays $400,000 for the steel. If antidumping duties increase from 5% to 15%, the annual duty cost rises from $20,000 to $60,000—a $40,000 impact that must be absorbed, passed to customers, or mitigated through alternative sourcing.

What Should Importers Do Right Now?

Immediate Actions (Within 30 Days)

1. Identify Your Exposure Review all entries of CTL plate from Korea made between February 1, 2024, and January 31, 2025. Check commercial invoices and customs entry documents to:

• Confirm the Korean producer/exporter name
• Verify entry dates and values
• Calculate potential additional duty liability

2. Verify Current Supplier Status Contact your Korean steel supplier to confirm:

• Whether they were reviewed in this proceeding
• What their final antidumping duty rate is
• How they plan to address duty costs (absorb vs. pass through)

3. Review Cash Deposit Status If you made entries during the review period, you posted cash deposits based on the prior rate. Once Commerce publishes the final results in the Federal Register, CBP will:

• Assess final duties at the new rates
• Issue bills for underpaid amounts (if new rates are higher)
• Process refunds for overpaid amounts (if new rates are lower)

Expect liquidation instructions from CBP within 90-180 days after publication of final results.

Strategic Planning (Next 90 Days)

4. Evaluate Alternative Sources Consider sourcing strategies to reduce antidumping duty exposure:

• Domestic suppliers: U.S. steel mills produce CTL plate without additional duties
• Non-subject countries: Steel plate from countries without dumping orders (though many major producers have similar orders)
• Different product specifications: Some end-use applications may accept alternative steel products outside the scope

5. Review Your Classification Work with a licensed customs broker to verify that your imports actually fall within the scope. Some steel plate products are excluded, and proper classification can save significant duty costs. Key questions:

• Does your plate meet the thickness requirements?
• Is it truly "cut-to-length" or does it qualify as a different product form?
• Are there any applicable exclusions?

6. Budget for Ongoing Costs Update financial projections to reflect the new duty rates. Antidumping orders typically remain in place for years unless revoked through a sunset review process.

Compliance Considerations

7. Maintain Detailed Records Keep comprehensive documentation for all steel plate imports:

• Commercial invoices showing Korean producer name
• Entry documents with HTS classification
• Correspondence with suppliers about pricing
• Payment records for duty deposits

The statute of limitations for Customs issues is typically 5 years. Proper documentation protects you in case of audits or duty rate corrections.

8. Monitor for Circumvention Commerce actively investigates attempts to evade antidumping duties through:

• Transshipping through third countries
• Minor alterations to products
• Misclassification schemes

Ensure your supply chain is compliant to avoid severe penalties, which can include duty assessment on the full value plus penalties of up to four times the lost revenue.

Understanding Antidumping Duty Calculations

Antidumping duties are calculated as the difference between the "normal value" (typically the price in the producer's home market) and the "export price" (the price when sold to the U.S.).

The duty margin is expressed as a percentage. For example:

• Normal value in Korea: $900/ton
• Export price to U.S.: $800/ton
• Dumping margin: ($900-$800)/$800 = 12.5%

This 12.5% rate is then applied to the entered value of future imports from that producer.

Important note: Rates vary by company. Korean Producer A might have a 5% rate while Producer B has a 15% rate based on their individual pricing behavior.

The Bigger Picture: U.S. Steel Trade Enforcement

This administrative review is part of a broader U.S. trade enforcement strategy targeting steel imports. The United States currently maintains antidumping and countervailing duty orders on steel products from multiple countries including:

• China (numerous steel product categories)
• South Korea (plate, pipe, and other products)
• Taiwan, Vietnam, Turkey, and others

Additionally, steel imports face:

• Section 232 tariffs: 25% on steel imports from most countries (some exclusions apply)
• Section 301 tariffs: Additional duties on Chinese steel products
• Countervailing duties: Targeting government subsidies in certain countries

For importers, this creates a complex web of overlapping duties that can total 50% or more of the product value.

Frequently Asked Questions

Bottom Line for Small Business Importers

The final results of this administrative review mean duty rates are now locked in for Korean CTL plate imports during the review period, and new rates apply going forward. Whether this increases or decreases your costs depends on your specific Korean supplier and their individual dumping margin.

The key action items:

1. Calculate your exposure on past entries (Feb 2024-Jan 2025)
2. Confirm current supplier rates for future budgeting
3. Evaluate sourcing alternatives if duties make Korean steel uncompetitive
4. Ensure proper classification and compliance with all requirements

Given the complexity of overlapping steel duties (antidumping, countervailing, Section 232, potentially Section 301), professional guidance is essential. Always consult a licensed customs broker for entry-specific advice and compliance questions.
