Section 301 tariffs on China under the Trade Act of 1974: list changes, the four-year review, rate increases and reductions, the granting, extension and expiry of exclusions, and USTR investigations and comment procedures.
CBP states in CSMS # 70261629 that ACE will accept entries under the conforming amendment to five Section 301 China product exclusions from 6 pm on October 23, 2026, reflecting USTR's Federal Register notices 91 FR 56538 and 91 FR 64211 and the July 1, 2026 changes to ten-digit HTSUS statistical reporting categories. The amendment revises U.S. notes 20(vvv)(i)(4), (i)(5), (i)(6), (i)(20) and (iv)(4) to subchapter III of chapter 99, all reported under 9903.88.69, replacing classifications 8413.91.9065, 8413.91.9085, 8413.91.9096, 3926.90.9910 and 8479.90.9596 with 8413.91.9039, 8413.91.9046, 8413.91.9059, 8413.91.9099, 3926.90.9915, 3926.90.9920 and 8479.90.9591. Importers must not submit the corresponding Chapter 99 HTSUS number for Section 301 China duties when 9903.88.69 is submitted.
Why it matters: Entries of goods under these five exclusions must use the new statistical reporting numbers from July 1, 2026, and ACE accepts the conforming amendment from 6 pm on October 23, 2026.
CBP extended the compliance date for the new informal entry procedures for international mail from Oct. 22, 2026, to Jan. 20, 2027, a 90-day extension. Beginning Jan. 20, 2027, international postal shipments subject to Section 201, 232 or 301 duties, or within the jurisdiction of a Partner Government Agency, must be filed electronically in the Automated Commercial Environment through the new Entry Type 13 process for informal entry; otherwise formal entry is required. There are no changes to international mail entry procedures before that date, and CBP encourages filers to use the optional Entry Type 13 process during the transition.
Why it matters: Filers of international postal shipments subject to Section 201, 232 or 301 duties or PGA jurisdiction have until Jan. 20, 2027 to file those informal entries electronically through Entry Type 13.
CBP states in CSMS # 69990649 that USTR's Federal Register notice 91 FR 56538, published September 2, 2026, amends four Section 301 China product exclusions to conform with HTSUS ten-digit statistical reporting changes effective July 1, 2026, and that ACE will accept the conforming amendment from noon on September 23, 2026. U.S. notes 20(vvv)(i)(4), (i)(5) and (i)(6) under 9903.88.69 now cover statistical reporting numbers 8413.91.9039, 8413.91.9046, 8413.91.9059 and 8413.91.9099, which were previously classified under 8413.91.9065, 8413.91.9085 or 8413.91.9096 through June 30, 2026. U.S. note 20(vvv)(iv)(4) under 9903.88.69 now covers 3926.90.9915 and 3926.90.9920, previously classified under 3926.90.9910.
Proclamation 11062 of September 8, 2026 excludes certain products of Canada, as set forth in its Annex, from importation into the United States, effective for goods imported on or after 12:01 a.m. eastern time on September 29, 2026. The proclamation states that Canada maintained the dairy tariff-rate quota allocation measures found in Proclamation 11047 to discriminate against U.S. commerce, and that the 50 percent duty imposed by Proclamation 11047 took effect August 22, 2026 after the 3-day suspension in Proclamation 11056 lapsed.
Why it matters: Entries of the Canadian products listed in the Annex on or after September 29, 2026 are excluded from importation, while goods imported but not yet entered or withdrawn from warehouse before that date remain subject to the 50 percent duty rate under Proclamation 11047.

A presidential proclamation signed September 8, 2026 excludes certain products of Canada, as set forth in its Annex, from importation into the United States, effective for goods imported on or after 12:01 a.m. eastern time on September 29, 2026. The excluded products are those currently subject to the additional ad valorem duties imposed under Proclamation 11047, which took effect August 22, 2026 at a 50 percent rate after the 3-day suspension in Proclamation 11056 lapsed. Goods imported but not yet entered for consumption, or withdrawn from warehouse for consumption, before September 29, 2026 remain subject to the 50 percent duty rate.
Why it matters: Importers of the Canadian products listed in the Annex must have goods entered for consumption or withdrawn from warehouse before 12:01 a.m. eastern time on September 29, 2026 to remain under the 50 percent duty rather than the import ban.

In Slip Op. 26-102, Court No. 22-00056, the U.S. Court of International Trade granted Zoetis Services LLC's motion for summary judgment and denied the government's cross-motion, holding that feed-grade chlortetracycline concentrate manufactured in China by Jinhe Biotechnology Co., Ltd. is properly classified as an antibiotic under subheading 2941.30.00 rather than as an animal feed preparation under heading 2309. CBP had liquidated two Chicago entries, dated December 26, 2019 and January 22, 2020, under subheading 2309.90.10 and assessed Section 301 duties under 9903.88.03 at 25 percent ad valorem; the government argued on cross-motion for subheading 2309.90.95 at 1.4 percent.

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.
