Entry practice: ACE system changes and filing fields, liquidation and extensions, protests, post summary corrections (PSC), prior disclosures, drawback, and the operational positions CBP gives in CSMS messages.
Global Affairs Canada states in Notice to Importers Serial No. 1168 that imports of electric vehicles originating in China under Import Control List items 195(1) to (3), classified in tariff items 8702.20.10 through 8704.90.00 or a Chapter 99 tariff item, require a shipment-specific import permit and are administered under a first-come, first-served quota, with 24,500 vehicles available for the second period of Quota Year 1 from September 1, 2026 to February 28, 2027, plus unused volumes from the first period. Eligible EVs enter at a most-favoured-nation rate of 6.1%, and importers must be Canadian residents that are EV original equipment manufacturers or their appointed Canadian-resident agents.
CBP published a final rule on August 26, 2026 requiring electronic transmission of export manifest data in ACE for cargo departing the United States by rail, including trains to Mexico and Canada. The rule identifies the parties eligible to transmit and the time frames before departure in which the information is due. It is effective October 26, 2026, and CBP will begin enforcing it on October 26, 2027.
Why it matters: Rail carriers and other eligible parties must file export manifest data electronically in ACE before departure, with CBP enforcement beginning October 26, 2027.
CBP states in CSMS # 69668138 that it has updated the order of reporting multiple HTSUS classifications on the same ACE entry summary line when a Chapter 98 or 99 classification is claimed. The sequence is Chapter 98 (if applicable), then Chapter 99 additional-duty classifications, then Chapter 99 replacement-duty or other-use classifications, then other quota Chapter 99 classifications, then the Chapter 1 to 97 classification. Within trade remedies, filers report Section 301 first, followed by Section 338, Section 232, Section 201 duties and Section 201 quota. The entered value is reported on the Chapter 1-97 classification unless Chapter 98 provisions require otherwise.
Why it matters: Importers filing entry summaries that claim Chapter 98 or 99 classifications must report the HTSUS classifications on each line in the sequence CSMS # 69668138 sets out, with Section 301 reported first among trade remedies.
CBP states in CSMS # 69657207 that it rescinds support for the "Flying Trucks" process, effective immediately, and will no longer authorize air manifests for cargo arriving at the border via truck; carriers must transmit advance electronic manifest information matching the mode of transportation that crosses the border, as required by 19 CFR § 123.92. CBP provides a 90-day transition period for express carriers to update systems and procedures, with an effective date of termination on November 24, 2026. All express carriers and stakeholders participating in the process must align operations with standard truck manifest requirements by that date. Non-compliance may trigger delays, penalties or other enforcement actions.
CBP states in CSMS # 69635410 that ACE CATAIR Error Dictionary V52 adds error F883, PSC NOT ALLOWED TO MODIFY IEEPA HTS, which prevents filers from submitting a Post Summary Correction for a Foreign Trade Zone entry type 06 if the IEEPA HTS is modified in any way. The updated dictionary is posted under the Supporting Documents: Documentation for Entry Summary Chapters section on CBP.gov, and the update was deployed to the CERTIFICATION and PRODUCTION environments on August 21, 2026. Technical questions go to the assigned Client Representative, and questions or concerns to the Entry Summary Accounts & Revenue Division at esar@cbp.dhs.gov.
Why it matters: Filers of FTZ entry type 06 cannot use a Post Summary Correction to change an IEEPA HTS, and the F883 validation is already active in both CERT and PROD.
CBSA states in Customs Notice 26-20 that goods subject to tariff rate quotas entered into a customs bonded warehouse must have a valid shipment-specific import permit issued by Global Affairs Canada to be accounted for at the "within access" rate of duty, and that the permit's validity period must cover the date the goods exit the warehouse. The notice says this is a clarification of existing application, not a change in policy, and applies to all goods subject to TRQs.
Why it matters: Importers using a customs bonded warehouse must hold a shipment-specific import permit valid through the date goods exit the warehouse, and must amend the Type 10 CAD before filing an ex-warehouse movement at the "within access" rate.
CBSA states in Customs Notice 26-16 that rail carriers reporting domestic in-transit cargo moving between points in Canada through the United States (CAN-US-CAN) must now select "Rail In-transit Manifest" in the Movement Type Code field of the ACI/eManifest cargo transmission, the same movement type used for other in-transit movements, instead of transmitting the cargo as an import with "in-transit Canadian origin goods" in the special instructions field.
The Canada Border Services Agency states in Customs Notice 26-15 that, when the Order Amending the General Import Permit No. 83 — Aluminum Products comes into force on October 1, 2026, importers must submit the country of largest smelt (CLS), country of second-largest smelt (C2S) and country of most recent cast (CRC) to the CBSA via the Single Window Initiative Integrated Import Declaration; until then submission is optional. The requirements apply to all aluminum HS codes in Global Affairs Canada's SWI IID Regulated Commodities Data Element Matching Criteria Table, and cover goods containing primary aluminum for CLS and C2S and all goods covered by GIP 83 for CRC.
Global Affairs Canada's Notice to Importers Serial No. 1163, effective June 13, 2026, replaces Serial No. 1160 and sets out the policies and procedures for administering the tariff-rate quotas on certain steel goods in item 82 of the Import Control List, above which a 50% surtax applies. The Third Amending Surtax Order, effective June 28, 2026, adjusts TRQ volumes for the Hot-Rolled Sheet, Cold-Rolled Sheet, Hot-Rolled Bar, Structural Steel and Stainless Steel Billets and Blooms classes from non-FTA partners and the Hot-Rolled Sheet, Steel Plate and Cold-Rolled Sheet classes from non-CUSMA FTA partners, and reassigns certain tariff classification numbers from the Hot-Rolled Sheet to the Cold-Rolled Sheet class.
President Donald Trump signed the executive order "Strengthening Customs Enforcement" on June 3, 2026, directing CBP to require importers, domestic and foreign, to provide more detailed information about their ownership, business operations and supply chain and to maintain good standing with CBP to keep importing. Customs brokers will be held to higher standards and must conduct greater due diligence on their importers, foreign importers face heightened import restrictions, and bond rules are being updated to set new minimums and leverage against risk. The order does not state effective dates or the specific information importers must submit.
Why it matters: Importers and customs brokers covered by the order face new ownership, operations and supply chain reporting duties, higher broker due diligence standards and updated bond minimums, with importing privileges at risk for non-compliance.
CBP states that the U.S. Department of the Treasury will stop issuing paper checks for all CBP refunds on Feb. 6, 2026, unless the recipient has an approved waiver under 31 C.F.R. § 208.4, and that two upgrades to the ACE Secure Data Portal prepare users for the electronic refund process. The changes, outlined in the Interim Final Rule: Electronic Refunds, follow Executive Order 14247 on modernizing federal payments. The first upgrade adds a secure online tool for authorizing electronic refunds and the second simplifies the application process for creating importer accounts.
Why it matters: Importers, brokers and other refund recipients must be enrolled for electronic refunds through the ACE Portal before Feb. 6, 2026, or hold an approved waiver under 31 C.F.R. § 208.4 to keep receiving paper checks.
CBSA states in Customs Notice 25-31 that the January 1, 2026 Departmental Consolidation of the Customs Tariff (T2026) is now available on the CBSA website in various formats. T2026 reflects scheduled duty rate reductions under individual free trade agreements and the substitution of certain tariff classification pre-ambles and tariff classification numbers in chapters 28, 29, 73 and 81. Changes are marked by a change bar in the PDF version, by the number 1 in the change column of the Access files, and are not marked in the HTML version; concordance tables are also provided.
Global Affairs Canada states in Notice to Importers SER 1133 that, effective November 5, 2024, importers using General Import Permit No. 80 – Carbon Steel and General Import Permit No. 81 – Specialty Steel Products must provide country of melt and pour information at the time of importation as a term and condition of the permits. The requirement covers carbon steel under HS headings 7206-7217, 7225-7229, 7301-7302, 7304-7306 and 7308, and specialty steel under HS headings 7218-7224, 7312-7313 and 7317.
Why it matters: Importers of carbon and specialty steel under GIP No. 80 or GIP No. 81 must report country of melt and pour at the time of importation, for example through the Single Window Integrated Import Declaration, unless an exemption applies.

Global Affairs Canada states that certain Export and Import Controls System (EICS) commodity codes change effective January 1, 2022, following World Customs Organization HS code updates and related Customs Tariff updates, and that permit and certificate applications with an entry or exit date after December 31, 2021 for the affected goods must use the new commodity codes.
Global Affairs Canada states in Notice to Importers No. 1032 that, effective November 2, 2020, item 80 (Carbon Steel Products) and item 81 (Specialty Steel Products) of the Import Control List have been re-added following their deemed removal on November 1, 2020, and the associated HS codes amended. Carbon steel covers HS headings 7206-7217, 7225-7229, 7302 and 7304-7306; specialty steel covers HS headings 7218-7224, 7301, 7308, 7312-7313 and 7317. The changes do not limit the quantity of carbon or specialty steel that may be imported into Canada, and the new items have no deemed removal date.
Why it matters: Importers and customs brokers using GIP No. 80 or GIP No. 81 must state the applicable permit on the customs documentation for shipments under HS headings 7206-7302, 7304-7306, 7308, 7312-13 and 7317, and retain the prescribed records for six years.
