Tariff Radar

Treasury Secretary Bessent announced on 2026-09-23 (Fox News interview, during President Xi's Washington visit) a two-month extension of the Busan-agreement truce: the truce elements — the 24% reciprocal suspension, the fentanyl rate, the 178 China 301 exclusions and the port-fee suspension — now run to 2027-01-10 instead of 2026-11-10. Note: a cabinet-secretary statement so far (per Politico/Reuters/CNBC); the Federal Register implementation is pending — until then, entries keep their FR-confirmed dates. The Radar tracks follow-through.

Scope: Truce scope (reciprocal suspension / 178 Section 301 exclusions / port-fee suspension)

NHTSA, on behalf of the U.S. Department of Transportation, finalizes a substantial recalibration of the Corporate Average Fuel Economy (CAFE) program (91 FR 61988, published 2026-09-30, effective 2026-11-30): amendments to fuel-economy standards for light-duty vehicles (passenger cars and light trucks) for model years 2022-2026 and 2027-2031, plus compliance aspects including vehicle classification and other compliance pathways. Vehicle fuel-economy regulation only — unrelated to U.S. import-duty calculation and no HTS rate change; the notice states no specific figures, see the FR document for details.

Scope: None (vehicle fuel-economy regulation; no HTS codes)

178 China Section 301 product exclusions (incl. fasteners) run through 2026-11-10; after expiry the affected HTS codes revert to their list rates (e.g. List 3 at 25%) (2026-09-23 update: a two-month truce extension to 2027-01-10 was announced; until FR implementation this entry stands as of 2026-11-10 — see the 2027-01-10 Radar entry.)

Scope: HTS codes covered by the 178 exclusions

The Federal Maritime Commission (FMC), under the Paperwork Reduction Act, opens a 60-day comment period on the renewal of the information collection for Carrier Automated Tariffs (46 CFR part 520, OMB 3072-0064, currently approved through 2027-01-31) and the related Form FMC-1 (91 FR 65553; comments due 2026-12-14; docket FMC-2026-0431). Review type: extension with change — burden estimates are raised because the number of respondents has grown, and Form FMC-1 remains electronic but is being folded into the agency's ServiceNow modernization platform. Burden estimates: ~9,324 carrier automated tariffs, 189,134 annual responses, 0.017–2 person-hours per response (~0.25 for Form FMC-1), 4,740.03 total annual person-hours. Under section 8(a) of the Shipping Act of 1984, common carriers and conferences must keep their rates, charges, classifications, rules and practices open to public inspection in an automated tariff system — this notice is the paperwork-approval renewal of that obligation, i.e. procedural only, with no duty-rate change.

Scope: None (carrier automated tariffs paperwork notice; no HTS codes)

USITC notice (91 FR 65254): on a complaint filed by Vicor Corporation (Andover, MA) on 2026-09-09 and supplemented 2026-09-10, the Commission instituted investigation No. 337-TA-1526 on 2026-10-09 — the accused products are vertical power delivery systems and components thereof used in data center server, AI and cloud computing systems to power AI accelerators, TPUs, GPUs and CPUs, and computing systems containing the same; the alleged violation rests on infringement of certain claims (1-8, 11-14, 18-26, 40-56, 65-71, 80, 81, 83, 84, 90-93, 95) of U.S. Patent No. 10,903,734 ('734 patent). The 20 named respondents span Taiwan, Germany, mainland China, the US and Canada: Delta Electronics (and Americas arm), DET Logistics, Infineon Technologies AG, Luxshare Precision and Dongguan Luxshare, Monolithic Power Systems (incl. Chengdu/Shanghai entities), Flex, Celestica, Quanta Computer/Quanta Cloud (and US arms), Hon Hai/Foxconn, Foxconn Industrial Internet (FII) and Ingrasys; the complainant requests a limited exclusion order and cease-and-desist orders, and respondents must answer within 20 days of service. This notice is a procedural 337 institution announcement and does not change any tariff rate; a subsequent violation finding could lead to a limited exclusion order (import relief, not duties). See the FR notice for details.

Scope: No specific HTS codes listed (accused products: vertical power delivery systems and components used in data center server, AI and cloud computing systems to power AI accelerators, TPU, GPU and CPU, and computing systems containing the same)

Per clause (2)(d) of Proclamation 11032 (June 1, 2026, 91 FR 34085, "Further Adjusting the Tariff Regimes for Imports of Aluminum, Steel, and Copper into the United States", modifying the metal tariff regimes of Proclamations 9704, 9705 and 10962), the Commerce Department's Bureau of Industry and Security (Docket 260918-0056, XRIN 0694-XC163) issued guidance to CBP defining "U.S. content": (1) the value of the product attributable to parts wholly obtained, entirely produced, or substantially transformed in the United States; and (2) to the extent not otherwise accounted for in (1), the value attributable to steel melted and poured in the US, and aluminum and/or copper smelted and cast in the US. The guidance applies to products of Canada and Mexico qualifying for USMCA preferential tariff treatment, effective for goods entered for consumption or withdrawn from warehouse for consumption on or after 12:01 a.m. ET on 2026-10-14 — the first official articulation of this test; the notice sets no new rate values. See the FR notice for details.

Scope: USMCA-qualifying Canada/Mexico goods under Section 232 steel/aluminum/copper coverage (no specific HTS codes listed)

U.S. Customs and Border Protection (CBP) issued a notice of proposed rulemaking (91 FR 64840; Docket USCBP-2026-0992, RIN 1651-AB60): proposed new subpart K of 19 CFR part 123 (eight sections) would require rail carriers to transmit to CBP an advance notice of arrival or departure for any train entering, leaving, or transiting the United States with a traveler on board, plus advance electronic traveler information for each passenger and crew member — converting the current voluntary rail/bus APIS submissions into a mandatory requirement (OMB collection 1651-0088 would be amended; estimated ~141,381 additional annual responses and 6,512 burden hours). Comments are due December 14, 2026. Procedural rulemaking notice on border-security filing procedures — no tariff-rate changes; no specific duty values are given, see the FR text.

Scope: Rail traveler reporting obligations (border filing procedure; no specific HTS provisions involved)

The U.S. International Trade Commission (91 FR 64398) gives notice that, on a complaint filed September 3, 2026 and supplemented September 17, 2026 by trinamiX Sensing LLC (Austin, TX) and trinamiX GmbH (Germany), the Commission instituted on October 5, 2026 a Section 337 investigation (No. 337-TA-1525) concerning certain mobile electronic devices and components thereof — the accused products are iPhones and iPads and components such as processors and TrueDepth camera modules (VCSEL, flood-illumination VCSEL, and near-infrared camera components with face authentication, 3D-sensing, and/or material detection capabilities). Respondent: Apple Inc.; six patents alleged ('925, '421, '334, '760, '394, '352). Complainants request a limited exclusion order and cease-and-desist orders. Institution itself changes no tariff rates; an exclusion order could result if a violation is ultimately found.

Scope: No specific HTS numbers are listed in the notice (accused products: iPhones/iPads and components such as processors and TrueDepth camera modules)

CBP published a notice of proposed rulemaking (91 FR 64532; docket USCBP-2026-0298) to rework low-value shipment processing following the suspension of the de minimis exemption, amending 19 CFR parts 113, 128, 141, 143, and 145: (1) the informal entry (ET11) deadline would tighten from 15 days after arrival to on or prior to the date of importation, with a new final deliver-to party data element; (2) the $250 informal-entry eligibility cap for HTSUS Chapter 99 Subchapters III/IV goods (e.g., Section 232/301 goods) would be removed, so goods of $251–$2,500 would no longer be barred from informal entry; (3) mail shipments of $2,500 or less would be required to file via a new electronic informal mail entry type 13 (new data elements for filers and carriers), and mail articles not entered within 15 days of importation would be deemed voluntarily abandoned (processed per USPS procedures, possibly destroyed or returned); (4) all ET11/ET13 filers would need a basic importation and entry bond, with a $1,000 floor on liquidated damages. Proposed rule only — comments due December 7, 2026; not yet in effect and no tariff rates are changed.

Scope: Not tied to specific HTS lines — applies to low-value shipments valued at $2,500 or less (including Chapter 99 Subchapters III/IV goods, where informal entry would be opened for the $251–$2,500 range); amends 19 CFR parts 113, 128, 141, 143, 145

Following the USITC's July 1, 2026 changes to ten-digit HTSUS statistical reporting categories (under 19 U.S.C. 1484(f)), five China Section 301 product exclusions were affected; four were corrected by USTR on September 2, 2026 (91 FR 56538). This notice (91 FR 64211) makes the final conforming amendment: U.S. note 20(vvv)(i)(20) to subchapter III of chapter 99 is modified by inserting "through June 30, 2026; described in statistical reporting number 8479.90.9591 effective July 1, 2026" after "January 27, 2022" — i.e., from July 1, 2026 the covered product is described under the new statistical reporting number 8479.90.9591. This is a technical amendment to maintain the pre-existing exclusion coverage: the exclusion continues to bar the additional Section 301 duties, and no rate is added or raised. Retroactive to goods entered for consumption, or withdrawn from warehouse for consumption, on or after 12:01 a.m. EST July 1, 2026; CBP will issue entry guidance.

Scope: Product covered by the U.S. note 20(vvv)(i)(20) exclusion — statistical reporting number 8479.90.9591 (within 8479.90.95)

A GEO applies regardless of who imports the products — entry of any infringing articles within the scope is barred, and importers must show their goods fall outside the patent claims to secure release. This is an IP-based import-relief order: it bars the infringing products from importation and changes no tariff rates; exporters to the U.S. of automotive cooling-system maintenance products (e.g. coolant supplement-type items) should assess whether their products fall within the patent claims. No specific values are given, see the FR text.

Scope: Certain boiler protection for absorption refrigeration systems and components thereof (per the GEO scope)

The Office of the United States Trade Representative (USTR) announced the Fiscal Year 2027 (October 1, 2026 through September 30, 2027) in-quota quantity allocations of the tariff-rate quota (TRQ) for imported raw cane sugar (91 FR 60487). The FY2027 in-quota quantity is 1,117,195 metric tons raw value (MTRV), the minimum amount committed under the WTO Agreement; 1,061,202 MTRV was allocated on July 24, 2026 (91 FR 46822), and this notice allocates the remaining 55,993 MTRV among 28 supplying countries (Dominican Republic 11,931; Philippines 9,151; Australia 5,626; Guatemala 3,254; Argentina 2,915; Peru 2,779; etc.). In-quota quantities may enter the United States as of October 1, 2026; imports from allocated countries must be accompanied by certificates of quota eligibility, and allocations to net sugar importers are conditioned on verifications of origin. The allocations are made pursuant to Additional U.S. Note 5 to Chapter 17 of the HTSUS; they adjust quota access quantities only and do not change in-quota or over-quota duty rates.

Scope: Raw cane sugar TRQ (under Additional U.S. Note 5 to HTSUS chapter 17; no specific HTS numbers listed in the notice)

In its quarterly notice (91 FR 60141), CBP advises, per 19 U.S.C. 1505 and T.D. 85-93, that for the calendar quarter beginning October 1, 2026 (through December 31, 2026), interest on underpayments of customs duties is 7% for both corporations and non-corporations, and overpayment interest is 7% for non-corporations and 6% for corporations — per IRS Revenue Ruling 2026-15 (4% federal short-term rate plus 3/2 percentage points). Routine quarterly interest notice; no tariff rate is changed. Note: the FR SUMMARY says the rates remain the same as the prior quarter, while the supplementary text says they increase — the document is internally inconsistent; this entry records the rates as stated. Prior-quarter values are not given; see the FR document.

Scope: No HTS impact (applies to interest on all customs underpayment/overpayment accounts)

The FDIC invites comment on a proposed rule (91 FR 60196; RIN 3064-AG18; amending 12 CFR parts 303, 314, and 333) that would reform how it processes and evaluates merger transactions under the Bank Merger Act; comments are due November 23, 2026. Key points: accounting for credit unions and centrally booked deposits in the initial competitive-effects analysis; a letter-filing process with "deemed approval" for de minimis merger transactions; tailoring filing burdens and processing times to a transaction's size and risk profile; and limiting FDIC discretion to remove filings from expedited processing while codifying its statutory-factor evaluation.

Per FR 2026-18839 (91 FR 58339), Proclamation 11065 modifies the scope of the 50% additional duty on Canadian motor vehicles under Proclamation 11048: products listed in Annex I Part A become subject to the duty and products in Part B are removed, with conforming HTSUS changes (Annex II), effective for goods entered for consumption, or withdrawn from warehouse for consumption, on or after 12:01 a.m. ET September 15, 2026.
