Korea Steel Quota Proposal Would Keep a 50% Tariff Floor
U.S. steel groups seek a Korea quota with tariffs of at least 50% inside it and a higher rate above it. Buyers would get no Section 232 tariff relief.

A quota on Korean steel would offer U.S. buyers no reduction in the current steel-mill tariff under the industry proposal issued September 28. The steel industry associations and United Steelworkers letter to Commerce and USTR, September 28, 2026 asks for a minimum 50 percent Section 232 tariff within a quota and a higher rate above it. Quota access would limit the tariff bill, but would offer none of the Section 232 exemption that Korean steel once received.
For a U.S. buyer approving a Korean steel supply contract, the risk is paying more for some of the planned tonnage. A signed order would not itself establish access to the lower rate. That would depend on rules the administration has yet to issue.
The letter creates neither a quota nor an entry rule. The immediate task is to test the contract against a possible higher rate, while retaining the current duty calculation for the purchase approval.
Three regimes, three different buying decisions
The old Korean arrangement traded a quantity restriction for an exemption from Section 232 steel duties. Proclamation 9740, clauses 1 and 2, established that structure in 2018. CBP administered the arrangement as an absolute quota with quarterly limits, as set out in CSMS 18-000342 on Korean steel quotas. Other applicable duties remained separate.
Proclamation 10896 ended Korea's alternative arrangement on March 12, 2025. Paragraph 17 explained the replacement as access from any source and in any quantity when the additional duties were paid, subject to other applicable law. The former quota stopped limiting shipments under that arrangement.
Korean steel restrictions as of September 29, 2026. Rates below concern Section 232, not all applicable duties.

Above-quota volume could remain available at a higher tariff cost
The requested tariff-rate quota would create two rate bands, allowing above-quota imports subject to a higher charge. How strongly the upper band restrains purchases depends on its rate and the cost of available substitutes.
The premium for missing in-quota treatment would be the gap between the two rates. The in-quota rate could itself exceed today's 50 percent, since the letter sets only a minimum. Neither rate nor the quota quantity is specified precisely enough to calculate what access to the lower band would be worth.
The 50 percent floor has a defined product scope
The current baseline matters because a reference to Korean steel can sweep in products with different treatment. Proclamation 11021, clauses 1 and 2 applies the Section 232 charge to full customs value and generally sets a 50 percent rate for covered steel articles and specified derivatives.
Other derivatives follow different schedules. Proclamation 11032 provides temporary separate treatment for specified equipment, including a combined Column 1 and Section 232 rate of 15 percent for eligible Korean Annex I-C goods when Column 1 is below 15 percent. The June equipment exceptions do not reduce the rate on Korean mill steel.
The purchasing memo should therefore identify the actual product classification before applying the proposed quota scenario. The letter does not provide an HTS schedule. Its references to long products, pipe and tube, and flat products do not establish the scope of a future government measure.
The August data show both a monthly decline and a large annual increase. In Census's September 24 release, Exhibit 3, preliminary August steel imports from Korea were 368,917 metric tons, against July's final 504,221. August was about 27 percent lower month on month but 131 percent above August 2025's 159,768. Exhibit 4 separately puts final January through July imports 43 percent above the same period in 2025. The August country figures remain subject to revision.
Those are all-steel totals. They do not reproduce the letter's selected product groupings or show how a particular product pool would fill. The decline from July does not disprove sustained elevated imports. It does show why treating one month's pace as a durable annual baseline can misstate the volume a new quota would constrain.
For a buyer, a national headline quantity is only the beginning. A common pool would allow different products to compete for the same lower-rate volume. Separate product limits could leave pipe subject to the higher rate while a sheet allocation remained available. A historical baseline could also preserve a product mix that no longer matches current purchases.
These are alternative designs, not announced rules. They explain why the threshold, measurement period and allocation unit would determine which shipments face the higher rate. A national import total cannot answer that purchasing question.
Price the contract before assuming quota access
The purchase approval memo should keep the current-law price alongside a contingent quota scenario. Classification, customs value and applicable duties determine the first calculation. For the scenario, separate firm orders from optional volume and record their expected entry periods. Either could face the higher rate. A commercial commitment does not establish customs quota eligibility.
A promise of access needs a basis in the eventual rules. The old arrangement supplies none by itself. CBP's termination notice required entries that had not obtained quota status by the March 11, 2025 cutoff to be refiled as non-quota entries the following day. Old allocations should not be carried forward as prospective rights.
The commercial question is which party would absorb the difference if a shipment attracts the higher rate, and whether the buyer could reduce or replace that volume without disrupting production. The memo can identify this exposure before a rate is known. It should not attach a numerical tariff saving to an allocation that does not exist.
Reprice the order when an operative government measure supplies the product coverage, quantities, rate bands and allocation rules. Those terms will establish which shipments qualify for the lower rate and whether the contract can absorb the cost of those that do not.
