ACE error dictionary adds validation codes for Entry Type 13 testing

ACE CATAIR Error Dictionary V54 adds nine entry-summary errors supporting the new Entry Type 13 Test. The additions address missing or invalid manifest-complying-party information, missing final-delivery information, an unknown ZIP code, and a dutiable-mail fee that is not allowed for the mode of transportation. The update also renames error B49 and revises errors concerning importer and consignee numbers, destination, mode of transportation, consolidation, Canadian province, merchandise processing fees, and charges. CBP posted the update on September 15, 2026, in the Draft Chapters: Future Capabilities section.

The change reaches filings made for the Entry Type 13 Test and affects how an entry-summary transmission is evaluated when one of the listed conditions is missing, unknown, invalid, or not allowed. The new validation messages include restrictions for manifest-complying-party information and dutiable-mail fees, while the renamed B49 message now states that a post-summary correction is not allowed when the entry cannot be informal or involves mail. The bulletin does not identify an HTSUS provision, duty rate, merchandise exclusion, or country-of-origin rule changed by this update.

CBP does not state an operational effective date for the updated dictionary or the Entry Type 13 Test. It says only that the updated version has been posted under Draft Chapters: Future Capabilities, and directs technical questions to the assigned Client Representative and questions or concerns to the Entry Summary Accounts and Revenue Division.

Section 338 exemption code now fails ACE validation without a dutiable Chapter 99 line

ACE entry-summary validation generates error F884 when exemption HTS 9903.03.05 is used for Section 338 without an appropriate dutiable Chapter 99 HTS reported on the same line. CBP deployed this validation to both the CERTIFICATION and PRODUCTION environments on August 26, 2026.

The rule reaches each entry-summary line that uses the Section 338 exemption code 9903.03.05. A line without an appropriate dutiable Chapter 99 HTS receives error F884, while the bulletin describes the presence of that HTS as the condition that avoids the stated error. The bulletin states no separate carve-out or transition rule; technical questions may be directed to the assigned CBP Client Representative.

FY27 COBRA fees and Entry Type 13 ACE filing rules change

FY27 Customs COBRA user fees and their limitations apply to importations effective October 1, 2026. The updated ACE CATAIR Entry Summary Create/Update V110 contains the fee amounts, but this notice does not state the figures. A summary pre-filed before October 1 still receives the new amount when its relevant entry date is October 1 or later.

The updated ACE CATAIR V111 adds ten changes for Entry Type 13 and three new Input 23-Record requirements; those updates are available in Certification and are scheduled for the Production environment on September 22, 2026. Entry Type 13 filers must consult the updated CATAIR for the exact data requirements, because this notice does not reproduce them. The fee change turns on the relevant entry date, while the filing changes turn on transmission to the ACE Production environment.

Listed scientific instruments approved for duty-free entry

Duty-free entry is approved for the foreign scientific instruments identified in the listed applications. The Department of Commerce made the decision under Section 6(c) of the Educational, Scientific, and Cultural Materials Importation Act of 1966 and states that no instrument of equivalent scientific value was being manufactured in the United States at the time of order. The approval is the operative customs result for the identified instruments.

The decision reaches the instruments and applicants identified by docket numbers 25-034 through 26-139 in the notice, including amplifiers, microscopes, cryogenic equipment, detectors, vacuum chambers, lasers, and other listed scientific instruments. It does not establish a general exemption for unlisted goods: the notice identifies the approved instruments individually, and it reports that no public comments were received. The source does not state a separate effective date or an additional filing procedure, so importers must use the listed instrument descriptions and docket scope when determining whether an entry falls within the approval.

India solar cells receive 126.09% final CVD rate, subject to ITC injury ruling

A 126.09% ad valorem countervailable-subsidy rate applies to Mundra Solar Energy Limited, Mundra Solar PV Limited, and all other producers and exporters for the April 1, 2024, through March 31, 2025 period. Commerce made the final affirmative determination applicable on September 16, 2026, but a CVD order and renewed suspension of liquidation will follow only if the U.S. International Trade Commission makes a final affirmative injury determination. If the ITC finds no material injury or threat, the proceeding ends and deposited duties are refunded or canceled.

The scope covers crystalline silicon photovoltaic cells from India, including cells assembled into modules, laminates, panels, and certain products assembled in third countries from Indian cells; the written scope controls over the listed HTSUS provisions. Thin-film products and the specifically described consumer-good, panel, and off-grid product exclusions are outside the scope. For entry timing, Commerce continued suspension for subject merchandise entered or withdrawn for consumption on or before June 25, 2026, and discontinued it for entries on or after June 26, 2026; critical-circumstances suspension reaches entries of merchandise produced or exported by Mundra Solar Energy or Mundra Solar PV on or after November 28, 2025. The ITC must determine injury within 45 days of Commerce's final affirmative determination, and an affirmative result would lead Commerce to issue a CVD order directing CBP to assess duties upon further instruction.

The notice does not itself establish the final cash-deposit or assessment operation of a CVD order because that step depends on the ITC's injury determination and subsequent Commerce instructions. Importers should therefore distinguish entries covered by the existing suspension history from later entries that remain subject to the pending ITC outcome.

Indian CSPV cells: 123.04% dumping margin and cash-deposit rate

A 123.04 percent estimated dumping margin and 123.04 percent cash-deposit rate apply to covered crystalline silicon photovoltaic cells, modules, laminates, and panels from India upon publication on September 16, 2026. Commerce made a final affirmative less-than-fair-value determination and instructed CBP to require deposits for covered entries. The listed respondents are Mundra Solar PV Limited, Mundra Solar Energy Limited, Kowa Company Ltd., and Premier Energies Photovoltaic Private Limited; the same 123.04 percent rate applies to all other producers and exporters. Although Commerce calculated rates adjusted for subsidy offsets at 107.17 percent, it is not instructing CBP to collect on that adjusted basis because provisional measures in the companion countervailing-duty case were discontinued.

The entry-date and company axes control suspension of liquidation. For subject merchandise produced or exported by Mundra Solar Energy, Mundra Solar PV, Kowa, or Premier Energies, liquidation remains suspended for entries or warehouse withdrawals for consumption on or after January 28, 2026; for all other companies, suspension applies on or after April 28, 2026. The scope covers CSPV cells at least 20 micrometers thick and specified modules, laminates, panels, and building-integrated materials, but excludes the listed thin-film products, qualifying consumer goods, specified off-grid products, certain third-country and other order-covered merchandise, and other products described in the appendix. The written scope description controls over the listed HTSUS classifications. The ITC must decide injury no later than 45 days after Commerce's final determination; a negative injury decision would terminate the proceeding, refund or cancel deposits, and lift suspension, while an affirmative decision would lead Commerce to issue an antidumping duty order.

Laos solar cells face 82.03% CVD rate and retroactive suspension

Estimated countervailing duty rates are 82.03% ad valorem for Solarspace Technology (Laos) Sole Co. Ltd. and all other producers or exporters, and 153.67% for Vietnam Sunergy Joint Stock Company. Commerce issued the final affirmative determination applicable September 16, 2026, and found critical circumstances for VSUN and all others, but not for Solarspace Laos. Commerce states that it will instruct CBP to suspend liquidation of covered VSUN and all-others entries entered or withdrawn from warehouse for consumption on or after November 28, 2025.

The shipment line is the entry or withdrawal date and the named producer or exporter. Covered entries from VSUN or other producers and exporters on or after November 28, 2025 are subject to the stated suspension of liquidation; entries from Solarspace Laos do not receive the critical-circumstances extension. The scope covers Lao crystalline silicon photovoltaic cells and modules, laminates, panels, and related products described in Appendix I, including modules made in a third country from subject-country cells, while modules made in Laos from third-country cells are excluded. The written scope description controls over the listed HTSUS classifications, and the notice also excludes specified thin-film products, qualifying consumer-integrated cells, specified off-grid panels, and products covered by the named prior orders.

The rates and suspension do not yet establish a permanent countervailing duty order on their own. Commerce states that an affirmative ITC material-injury or threat determination within 45 days would lead to a CVD order, reinstated suspension, and cash deposits at the stated rates; a negative ITC determination would terminate the proceeding and require deposited duties to be refunded or securities canceled. Importers should therefore preserve the entry records needed to identify the producer or exporter and the November 28, 2025 cutoff while the ITC determination remains pending.

Laos solar cells: 65.03% cash deposit rate subject to ITC injury finding

A 65.03% estimated antidumping cash deposit rate applies to the listed Laos solar-cell producer/exporter combinations and the Laos-wide entity if the U.S. International Trade Commission makes an affirmative injury determination. Commerce is continuing suspension of liquidation for subject entries entered or withdrawn from warehouse for consumption on or after April 28, 2026, and will instruct CBP to apply the suspension.

The rule reaches crystalline silicon photovoltaic cells, modules, laminates, and panels within the written scope, including certain products assembled after importation and modules made in a third country from cells produced in Laos. It excludes specified thin-film products, qualifying consumer-goods integrations, listed off-grid and portable panels, products covered by identified China and Southeast Asia orders, and modules made in Laos from third-country cells. The written scope controls over the listed HTSUS provisions; the producer/exporter combination controls the rate, with unlisted Laotian combinations receiving the Laos-wide rate and unlisted third-country exporters receiving the rate of the supplying Laotian producer/exporter or Laos-wide entity.

The ITC must issue its final injury determination no later than October 25, 2026, calculated as 45 days after Commerce's September 10, 2026 final determination. An affirmative ITC decision would lead Commerce to issue an antidumping duty order and direct CBP to assess duties; a negative decision would terminate the proceeding, refund deposited duties or cancel securities, and lift suspension of liquidation.

Indonesian solar cells: 73.20%–173.70% CVD rates set, ITC decision pending

Estimated countervailable subsidy rates are 173.70% for PT Blue Sky Solar Indonesia and 73.20% for PT REC Solar Energy Indonesia and all other producers and exporters. Commerce made the final affirmative determination applicable September 16, 2026, but a CVD order and renewed cash-deposit requirement still depend on the ITC's injury determination.

The scope covers Indonesian crystalline silicon photovoltaic cells and modules, laminates, and panels containing such cells, including certain products assembled in a third country from Indonesian cells; the written scope controls over the listed HTSUS provisions. Thin-film products and the numerous specified consumer-good, small-panel, off-grid, hydropanel, automation-device, and other exclusions are outside the scope. For entries, CBP was instructed to suspend liquidation and collect deposits for REC Solar merchandise entered or withdrawn on or after February 26, 2026, and for Blue Sky and all other producers or exporters on or after November 28, 2025; suspension was discontinued for entries on or after June 26, 2026 while entries on or before June 25, 2026 remain suspended. If the ITC finds injury, Commerce will issue a CVD order and reinstate suspension; if not, the proceeding ends and deposits or securities are refunded or canceled.

The ITC must make its final injury determination no later than 45 days after Commerce's final determination. Based on the September 16, 2026 publication date, that deadline is October 31, 2026. Until that determination and any resulting Commerce order, the packet does not establish a continuing final-order cash-deposit requirement for future entries.

Indonesian solar cells face a 94.36% antidumping margin and critical-circumstances suspension

A 94.36 percent estimated antidumping duty margin now applies for cash-deposit purposes to subject crystalline silicon photovoltaic cells, modules, laminates, and panels from Indonesia upon publication of the final determination. Commerce assigned that rate to PT Blue Sky Solar Indonesia, PT REC Solar Energy Indonesia, and all other producers and exporters, and directed CBP to continue suspension of liquidation for covered entries made or withdrawn for consumption on or after January 28, 2026, because critical circumstances exist.

The rule turns on the merchandise, producer, exporter, and entry date. Covered Indonesian solar cells and qualifying modules, laminates, or panels owe the 94.36 percent cash deposit; if the exporter is not listed but the producer is, the producer's rate applies, while all other producer-exporter combinations receive the all-others rate. The written scope controls, and it includes specified cells and products while excluding thin-film products, identified consumer goods and off-grid panels, and modules made in a third country from third-country cells.

The 94.36 percent deposit requirement is not yet an assured final duty assessment because the U.S. International Trade Commission must determine whether the domestic industry suffered or faces material injury. If the ITC finds no injury, the proceeding will end, posted deposits will be refunded, and suspension of liquidation will be lifted; if it finds injury, Commerce will issue an antidumping order directing CBP on assessment.

Italian cold-drawn mechanical tubing gets a 68.95% final AD margin for Dalmine

A 68.95 percent antidumping duty margin applies to Dalmine S.p.A. for the June 1, 2024, through May 31, 2025 period of review. Commerce will instruct CBP to assess that ad valorem rate on all appropriate entries of subject merchandise during the period. The cash-deposit requirement begins for covered shipments entered, or withdrawn from warehouse, for consumption on or after September 16, 2026, the publication date. Assessment instructions are not intended before October 21, 2026, which is 35 days after publication, unless the litigation procedure described in the notice affects liquidation.

The rule reaches cold-drawn mechanical tubing of carbon and alloy steel from Italy within the order's scope, but the notice says the complete scope description is in the Preliminary Results and does not reproduce it. Dalmine entries receive the 68.95 percent deposit rate; covered merchandise exported by a company outside this review but covered in a prior completed segment keeps that segment's most recent company-specific rate, and merchandise from an unreviewed exporter receives the producer's most recent completed-segment rate when the producer is covered. All other producers and exporters remain subject to the 47.87 percent all-others rate. Importers must file the reimbursement certificate required before liquidation of relevant period entries, or Commerce may presume reimbursement and assess double antidumping duties.

China L-lysine orders impose AD/CVD rates and service-list deadline

AD and CVD orders now apply to covered L-lysine from China. Effective September 16, 2026, CBP is to require cash deposits with estimated customs duties at AD rates of 139.65% for the China-wide entity and 73.37% for the specifically listed lower-rate combinations, and at CVD rates of 48.21% for Inner Mongolia Eppen and all others and 82.11% for Heilongjiang Wanli Runda and Shouguang Golden-land. The order states that the AD and CVD instructions remain in effect until further notice.

The covered merchandise is animal-feed-grade lysine, in forms including lysine hydrochloride, lysine sulfate, liquid lysine, and coated or encapsulated products; only the lysine component of a combined product is covered. The scope also reaches covered lysine processed in a third country. The written scope controls, while the listed HTSUS provisions are provided for customs convenience. AD assessment reaches unliquidated consumption entries from March 6, 2026, except entries from September 2 through September 7, 2026, which are to be liquidated without AD; CVD assessment reaches entries from January 22, 2026, except entries from May 22 through September 7, 2026, which are to be liquidated without CVD. AD suspension and collection resume September 8, 2026, while the CVD section specifies September 9, 2026.

Interested parties seeking placement on the annual inquiry service list must submit an entry of appearance in ACCESS within 30 days after publication of the order, making October 16, 2026 the computed deadline from the September 16 publication date. Commerce will create the list segment within five business days of publication, and the petitioner and foreign governments must make their initial appearances to be included in the first lists; later annual resubmission is not required for those parties, although amendments remain their responsibility.

The order states that Commerce will direct CBP to assess AD and CVD duties upon further instruction, so the assessment mechanics remain subject to those instructions. The notice itself nevertheless specifies the cash-deposit rates, the suspension dates, the entry-date boundaries, and the written scope that governs coverage.
