CBP Issued Filing Guidance for Section 232 Duties on Steel, Aluminum, Copper
CBP announced guidance implementing the April 2, 2026 proclamation that imposed additional duties of 10 to 50 percent on steel, aluminum, and copper articles and derivatives from all countries, effective April 6, 2026. The message explained how to report goods under HTSUS headings 9903.82.02 through 9903.82.17, including exclusions for goods with less than 15 percent metal content and higher rates for Russia-origin metals. It also covered country of melt and pour or smelt and cast reporting, drawback availability, and foreign trade zone and Chapter 98/99 treatment.
Show Allied's positionHide Allied's position
We apply these Section 232 additional duties to steel, aluminum, and copper entries that fall under HTSUS headings 9903.82.02 through 9903.82.17. Nothing in the background we track shows these duties were repealed, so this guidance still applies to entries we file today unless a later CSMS message changed it. Clients who import metal articles or derivatives should ask us to confirm the correct heading, metal content, and country of melt/pour or smelt/cast for their goods. Clients do not need to take independent action unless we request specific documents for a shipment.

CBP updated ACE guide with new DEA and CPSC tariff code flags
CBP announced an updated ACE Agency Tariff Code Reference Guide on March 23, 2026. The update revised the description for DEA flag DE1 and added new flag DE3. It also added two new CPSC flags, CP1 and CP2, to the guide.
Show Allied's positionHide Allied's position
This update concerns the technical reference codes brokers use when filing entries that involve DEA or CPSC data in ACE. It does not change any duty, tariff, or entry requirement for importers. Clients do not need to act, and we apply the updated codes in the filings we prepare.
CBP explained the 10 percent Section 122 import surcharge that applied earlier in 2026
CBP issued guidance on the February 20, 2026 proclamation that added a temporary 10 percent duty on imports from all countries under Section 122, effective February 24, 2026 through July 24, 2026. The message listed exemptions, including certain agricultural products, civil aircraft parts, USMCA-qualifying Canadian and Mexican goods, CAFTA-DR textiles, donations and informational materials. It also covered Chapter 98 treatment, foreign trade zone admission, drawback eligibility, and the required order for reporting HTS numbers on entry summaries.
Show Allied's positionHide Allied's position
This surcharge applied to entries Allied filed between February 24 and July 24, 2026, and is no longer in effect. Clients with entries from that window who believe an exemption applied, or who have questions about how it was applied to their goods, should ask us to review those specific entries. We do not need any action from clients now, since the surcharge period has ended.
CBP kept the de minimis suspension in place and added a 10% import surcharge in February 2026
CBP announced that, starting February 24, 2026, all goods lost eligibility for duty-free de minimis treatment, regardless of country of origin, except for limited items like donations and personal baggage. CBP also announced a 10 percent import surcharge on most goods entered on or after that date. International mail shipments were to keep following existing duty collection processes, and other shipments that previously qualified for de minimis had to be filed as a regular ACE entry type.
Show Allied's positionHide Allied's position
The 10 percent import surcharge described in this message applied only from February 24, 2026 to July 24, 2026 and has since ended. The de minimis suspension for all countries, including mail, remains in effect today, so we continue to file formal or informal entries for shipments that previously would have qualified for the de minimis exemption. If clients are unsure how this affects a specific shipment or entry, they should ask us to review it.
CBP stopped collecting IEEPA duties on goods entered from February 24, 2026
CBP announced that it would stop collecting IEEPA duties under seven executive orders, following the February 20, 2026 Executive Order "Ending Certain Tariff Actions." The change applied to goods entered, or withdrawn from warehouse, for consumption on or after 12:00 a.m. eastern time on February 24, 2026. CBP said the IEEPA HTSUS numbers would be inactive in ACE from that date. Duties under Section 232 and Section 301 were not affected.
Show Allied's positionHide Allied's position
This message meant that entries filed from February 24, 2026 no longer carried IEEPA duties, and that remains the case. Section 232 and Section 301 duties still apply where they cover the goods. CBP now refunds IEEPA duties paid on earlier entries through CAPE Declarations in the ACE Portal, not through post-summary corrections. Clients who paid IEEPA duties should ask us to review their entries for a CAPE refund claim.
Supreme Court Ruled IEEPA Does Not Authorize Tariffs
CBP announced that the U.S. Supreme Court ruled in Learning Resources, Inc. v. Trump that the International Emergency Economic Powers Act (IEEPA) does not authorize the President to impose tariffs. CBP said it was working with other agencies to examine the decision's implications and would issue further technical guidance for ACE filers. The message did not state any immediate change to entry filing procedures.
Show Allied's positionHide Allied's position
This ruling led to Executive Order 14389, which ended IEEPA duties the same day, and CBP later set up a refund process through CAPE Declarations in the ACE Portal. We apply these later rules when we review entries that carried IEEPA duties. Clients who believe they overpaid IEEPA duties should ask us to check their entries for refund eligibility.
CBP added duty checks in ACE for entries with up to 32 HTS codes per line
CBP announced that on February 17, 2026 it deployed an ACE enhancement that validates filer-provided duty amounts on entry summary lines listing up to 32 HTS codes. When a filer's duty amount does not match CBP's calculation, ACE returns condition code 624 for a line mismatch or 627 for a total mismatch. The message directed technical questions to CBP client representatives and other questions to CBP's ESAR email address.
Show Allied's positionHide Allied's position
This is a system level change to how CBP validates entry summary duty amounts, and it concerns the filing process rather than importer action. We account for these mismatch codes when we prepare and transmit entry summaries with multiple HTS codes per line. Clients do not need to do anything because of this message, but if a specific entry shows a duty discrepancy, clients should ask us to review it.

CBP dropped 25% Russia-related duty on India goods in February 2026, kept reciprocal tariffs
CBP announced that products of India entered on or after February 7, 2026 were no longer subject to the 25 percent additional duty imposed by EO 14329 on Russia-related threats, retiring HTSUS headings 9903.01.84-9903.01.89. Reciprocal tariffs under EO 14257 remained in effect for India goods that did not qualify for an exemption. CBP told filers to correct entries filed under the retired headings, using a post summary correction for unliquidated entries or a protest within 180 days of liquidation for liquidated entries.
Show Allied's positionHide Allied's position
This message predates the Supreme Court's February 20, 2026 ruling that IEEPA does not authorize tariffs and the EO 14389 order that ended IEEPA duties, including reciprocal tariffs, the same day. The PSC and protest process described here for correcting these entries has since been replaced by the CAPE Declaration refund process in the ACE Portal for IEEPA duties. Clients with India entries from this period should ask us to review whether their duties were refunded through CAPE rather than through the process this message describes.
CBP added a new ACE report to track Section 232 auto import adjustment offsets
CBP announced a new ACE Reports tool, TR-015 Section 232 Auto Credit, for importers and brokers with an ACE role. It shows entries filed with an offset license number for Section 232 duty offsets on automobile parts. The report helps track offset amounts claimed against limits set by the Department of Commerce.
Show Allied's positionHide Allied's position
This report is a tracking tool for clients who use Section 232 auto parts offset licenses. It does not change any duty rate or filing requirement, and Allied does not need to take new action because of it. Clients who use these offsets should ask Allied to review their entries if they want help monitoring their license balances.
CBP added more parties certified to pay duty on international mail shipments
CBP announced updates to its list of parties certified to collect and pay duty on international mail shipments under Executive Order 14324, which ended duty-free de minimis treatment for all countries effective August 29, 2025. CBP said mail carriers or qualified third parties must pay duty on these shipments, following the process in earlier CSMS guidance that requires a CBP Form 5106 and a bond. CBP said it would keep posting updated lists of qualified parties on CBP.gov.
Show Allied's positionHide Allied's position
This message concerns international mail carriers and third parties seeking CBP certification to pay duty on mail shipments, not entries Allied files directly. The de minimis suspension it references remains in effect for all countries, including mail, as of today. Clients who ship by international mail should confirm their carrier or designated party appears on CBP's current qualified party list, and can ask Allied to review how this affects their specific entries.
CBP added duty calculation error checks for entry summary filings in ACE
CBP announced in January 2026 that it enhanced ACE certification (CERT) to add two new validation codes, 624 and 627, that flag mismatches between estimated and calculated duty on entry summary lines with up to 32 HTS codes. CBP said the enhancement would move from CERT testing into ACE production on February 17, 2026. The message was aimed at software vendors testing ABI filing systems.
Show Allied's positionHide Allied's position
This update concerns the filing software and validation checks brokers like Allied use in ACE, not actions importers need to take. The new codes help catch duty calculation errors on entry summary lines before filing. Clients do not need to do anything; if a specific entry raises a duty mismatch question, we can review it on request.
CBP explained filing rules for 25% Section 232 duties on semiconductors (Jan 2026)
CBP issued guidance on the January 14, 2026 proclamation imposing a 25 percent Section 232 duty on certain semiconductors and derivative products, effective January 15, 2026. It listed HTSUS 9903.79.01 through 9903.79.09 covering duty rates and exclusions such as data centers, repairs, research and development, startups, and other listed uses. The message also set the required sequence for stacking Chapter 98 and Chapter 99 classifications, barred drawback for these duties, and set FTZ admission rules.
Show Allied's positionHide Allied's position
This guidance governed how we classified and filed entries for semiconductors subject to the January 2026 Section 232 proclamation. We applied the required HTSUS 9903.79 codes and duty stacking sequence to entries filed under that guidance at the time. Later CSMS messages may have changed rates, exclusions, or classification requirements since then, so clients should ask us to review their current semiconductor entries for what now applies.
CBP updated the list of qualified parties that pay duty on international mail
On January 14, 2026, CBP announced that it had certified additional parties to collect and pay duty on international mail shipments under Executive Order 14324. The list was attached to the message, and CBP said it would post and update the list on CBP.gov. Parties seeking certification had to file a CBP Form 5106, obtain a bond and meet other requirements. Parties with a Form 5106 and active bond on file could email CBPDM@cbp.dhs.gov to request qualification.
Show Allied's positionHide Allied's position
This message mattered to foreign postal operators and forwarders choosing who pays duty on mail shipments to the United States. De minimis remains suspended for all countries, including mail, so duty on mail still applies. The list of qualified parties may have changed since January, so check CBP.gov for the current list. Clients who want to act as a qualified party or need help with mail entries should ask Allied to review their situation.

CBP detailed new Reciprocal tariff rates for Swiss and Liechtenstein goods
CBP announced that, under a framework agreement, Reciprocal tariffs on covered products of Switzerland and Liechtenstein changed effective November 14, 2025. Products with a Column 1 rate of 15 percent or higher paid no additional Reciprocal tariff, while lower-rate products paid a combined 15 percent rate under new HTSUS headings. CBP also listed new exemptions for certain agricultural goods, natural resources, generic pharmaceuticals and civil aircraft articles, and told filers to correct prior entries by post summary correction or protest.
Show Allied's positionHide Allied's position
This message set duty rates and HTSUS headings for Swiss and Liechtenstein goods that Allied used at the time it was in effect. The Reciprocal tariffs it describes were IEEPA duties, and CBP ended all such duties on February 20, 2026, later moving refunds to CAPE Declarations in the ACE Portal instead of post summary corrections or protests. Clients with entries affected by this notice should ask Allied to review whether a CAPE Declaration or other later CBP guidance applies to their filings.

CBP published UK auto tariff rate quota bulletin for Q1 and Q2 2026
CBP announced Quota Bulletin 26-508 covering the tariff rate quota for UK-origin automobiles under Executive Order 14309. The bulletin set two quota periods for 2026, January 1 to March 31 and April 1 to June 30, with opening dates of January 2 and June 30. Entries filed after 12:01 am local port time and before 8:30 am ET on the opening date received an 8:30 am ET entry time for quota purposes, and CBP prorated accepted entries if a HTSUS group's limit was exceeded.
Show Allied's positionHide Allied's position
This bulletin covered UK automobile quota periods that have both closed as of today. It applied only to entries of UK-origin automobiles under the specified HTSUS Chapter 87 subheading filed during those quota windows. Clients who imported UK automobiles in Q1 or Q2 2026 and have questions about how their entries were processed should ask us to review the specific entries.

CBP corrected an HTS number for Korea reciprocal tariff reporting
CBP issued a correction to CSMS 66987366 about reciprocal tariffs on South Korean products. For products with a Column 1 duty rate below 15 percent, filers must use HTS heading 9903.02.80, not 9903.02.79, to report the combined 15 percent rate. The correction applied to entries for consumption or withdrawn from warehouse on or after November 14, 2025.
Show Allied's positionHide Allied's position
At the time, this correction told us which HTS heading to use when filing entry summaries for South Korean goods under the reciprocal tariff program. Later CSMS messages, including changes tied to the Supreme Court ruling on IEEPA tariffs, may have changed how this program applies. Clients with South Korean entries from this period should ask us to review the specific entries.
CBP detailed new Korea tariff rates for autos, wood, aircraft parts under trade deal (Dec 2025)
CBP announced guidance implementing tariff-related elements of the US-Korea Strategic Trade and Investment Deal, based on a December 3, 2025 Federal Register notice. It modified Section 232 duty rates on Korean automobiles, automobile parts, wood products and civil aircraft parts, and adjusted reciprocal tariff rates on Korean goods, with effective dates in November 2025. It also told filers how to correct entries already filed under the old rates, either by post summary correction before liquidation or by protest within 180 days after liquidation.
Show Allied's positionHide Allied's position
This message set specific Chapter 99 duty rates and reporting sequences for Korean-origin autos, auto parts, wood products, aircraft parts and general reciprocal tariff goods filed in late 2025. The reciprocal tariff portions relied on IEEPA authority, which the Supreme Court struck down and CBP ended on February 20, 2026, so those specific reciprocal rates no longer apply as described here. Section 232 duties on autos and wood are a separate authority and may still be in effect, but later CSMS messages may have changed the rates further. Clients with Korea entries from this period should ask us to review how these changes affect their filings.
