USPS raises Priority Mail and Ground Advantage 6 percent from Oct 4 to Jan 17
USPS · Shipping & postal · Effective Oct 4 · in 23 daysEffective Oct 4in 23 days6/6claims matched to the source
Who does this affect?
Any seller shipping domestic parcels with USPS through the holiday season, and anyone whose checkout shipping rates or 3PL contract are pegged to USPS list prices.
What it costs
A 6.0 percent increase on every domestic Priority Mail, Priority Mail Express, Ground Advantage, and Parcel Select label from October 4, 2026 to January 17, 2027, at both retail and commercial prices.
Do this now
Reprice holiday shipping now: if your checkout or 3PL passes USPS list rates through, expect about 6 percent more on every domestic label from October 4 to January 17, and check whether your negotiated commercial rates follow the list before you set free-shipping thresholds for Q4.
The Postal Service's Governors set a time-limited peak-season increase of 6.0 percent on average for Priority Mail Express, Priority Mail, USPS Ground Advantage, and Parcel Select, in effect from October 4, 2026 until January 17, 2027, at both retail and commercial prices.

Act now
CBP will void importer numbers with inaccurate Form 5106 data from September 18
CBP · Tariffs & customs · Deadline Sep 18 · in 7 daysDeadline Sep 18in 7 days7/7claims matched to the source
Who does this affect?
Every importer of record, especially sellers whose broker or forwarder filled in the form, brands registered at a registered agent, mailbox, or 3PL address, and foreign sellers importing into the US.
What it costs
No fee. The cost of getting it wrong is a voided importer number and every shipment stuck until CBP reinstates it; the notice gives no reinstatement timeline.
Do this now
Before September 18, have your broker pull the Form 5106 on file and confirm the physical address is your real location (a home address is allowed), the email and phone are yours and not the broker's, and the EIN matches the IRS; correct it through ABI or your Center now, because a voided IOR number stops every shipment until CBP reinstates it.
Implementing Executive Order 14411, CBP is reviewing every importer of record's Form 5106 and, from September 18, 2026, will void the IOR number of any importer whose physical address, email, phone, or EIN is inaccurate, incomplete, or belongs to someone else, which stops that importer from making entry.

FTC order names the e-commerce merchant profile processors must refuse
FTC · Payments & fraud · Published Sep 8Published Sep 85/5claims matched to the source
Who does this affect?
New online stores, sellers using a UPS Store or virtual address as their business address, and anyone running subscription or negative-option billing.
What it costs
$12 million paid by the processor, not by sellers. For a store that gets dropped, the cost is a frozen merchant account, held reserves, and weeks without payouts.
Do this now
If your business address is a mailbox service, expect processors to ask for a physical location, bank history, and chargeback data before approving you. Keep chargebacks well under card-network thresholds and never split volume across multiple merchant accounts to hide it.
Humboldt Merchant Services will pay $12 million to settle charges it processed payments for sham merchants. The order bars it from serving online sellers that use a mailbox-only address and either bill on a negative option, are new, or have no processing history.

Matched to source. Humboldt pays $12 million and is permanently banned from processing for higher-risk merchants.
Matched to source. The order bars processing for e-commerce businesses with a mailbox-only address that use negative option billing, are new, or lack processing history.

Section 232 drone duties of 25 to 100 percent took effect September 3
CBP · Tariffs & customs · Effective Sep 3 · In forceEffective Sep 3In force7/7claims matched to the source
Who does this affect?
Anyone importing or selling drones, drone docking stations, or drone parts, including camera and hobby drones sold on Amazon and Shopify, from any country of origin.
What it costs
An additional 100% of customs value on drones with thermal imaging, docking stations, and parts for drones over 25 kg, and 25% on other drones, on top of existing duties, for goods entered on or after September 3, 2026; a further 25% on the remaining drone parts from February 9, 2027.
Do this now
If you sell drones or drone parts, get the HTS classification of every SKU from your broker this week and check whether it falls in the 100 percent group (thermal imaging, docking stations, parts for drones over 25 kg) or the 25 percent group; reprice or pause inbound orders accordingly, and diarize February 9, 2027 for the remaining parts.
CBP's guidance implements Proclamation 11055: unmanned aircraft with thermal imaging, docking stations, and parts for heavy drones pay an additional 100 percent, drones without thermal imaging pay 25 percent, and a 25 percent duty on the remaining drone parts starts February 9, 2027, all on top of existing duties and from every country.

Section 301 tariffs of 10 or 12.5 percent hit all goods of 60 economies from July 24
USTR · Tariffs & customs · Effective Jul 24 · In forceEffective Jul 24In force7/7claims matched to the source
Who does this affect?
Every importer sourcing from any of the 60 economies whose products are not on the exemption annexes; apparel importers from Bangladesh, Cambodia, Indonesia, and Malaysia pay 10 percent until the promised textile quotas exist.
What it costs
An additional 10 percent or 12.5 percent of customs value on nearly all imports from the 60 economies since July 24, 2026, on top of existing duties, unless the product appears in the exemption annexes.
Do this now
Pull a duty report by country of origin for entries since July 24 and confirm your broker applied the right Section 301 rate (10 or 12.5 percent, or net of the MFN rate for EU, Japan, Korea, Switzerland, and Taiwan goods) and checked the exemption annexes; any landed-cost sheet built before July 24 is wrong for almost every origin.
USTR imposed additional Section 301 duties on all products of 60 economies, including China, Vietnam, India, the EU, Japan, Korea, the UK, Canada, and Mexico, for failing to impose or enforce a forced-labor import ban: 10 percent for economies with a ban or a reciprocal-trade commitment, 12.5 percent for the rest, with exemptions in two annexes and a four-day grace period for goods already in transit.

What it costs
Re-testing every SKU that contains a coin cell if the revised standard changes a test you rely on; the notice gives no cost estimate.
Do this now
If you sell anything with a coin or button cell, ask your supplier which edition of UL 4200A the test report cites. If the revision changes a test you rely on, comment on docket CPSC-2023-0004 before September 17.
UL revised the standard that CPSC's mandatory button-battery rule incorporates. Unless CPSC rejects the revision within 90 days, the new version becomes the mandatory standard automatically.

CBP weighs requiring foreign export documents and supplier IDs on every entry
CBP · Tariffs & customs · Deadline Dec 1 · in 81 daysDeadline Dec 1in 81 days6/6claims matched to the source
Who does this affect?
Every importer of record, especially brands that buy through trading companies or third-party logistics providers and marketplace sellers whose supplier paperwork never reaches them.
What it costs
No cost yet. If adopted, every entry could carry a document-collection burden and a supplier-identifier requirement; CBP asks commenters to quantify those costs and whether small entities should get a longer implementation timeline.
Do this now
Ask your supplier or forwarder this week whether you can get copies of the export declaration and commercial invoice they file abroad, and how long that takes; if the answer is no or weeks, say so in a comment on docket USCBP-2026-1058 before December 1. Small importers who stay silent get a rule written for large ones.
An advance notice of proposed rulemaking asks whether importers of record should submit the export declaration, invoice, and origin certificate their supplier filed abroad, replace the manufacturer ID code with real identifiers, name the marketplace that facilitated a sale, and file entries sooner. Comments are open until December 1, 2026; nothing changes yet.

CBP raises the merchandise processing fee cap to $670.86 per entry on October 1
CBP · Tariffs & customs · Effective Oct 1 · in 20 daysEffective Oct 1in 20 days4/4claims matched to the source
Who does this affect?
Every importer filing formal entries, most sharply those whose entry values are large enough to hit the per-entry cap, plus anyone paying informal entry, dutiable mail, or express consignment fees.
What it costs
Merchandise processing fee limits move to a 34.58 minimum and a 670.86 maximum (in dollars) per formal entry from October 1, 2026, up 2.84 percent; the 0.3464 percent rate is unchanged, so entries between the floor and the cap pay the same as before.
Do this now
If a single entry is worth more than about $193,700 (the cap divided by the 0.3464 percent rate), the cap binds and each formal entry costs $670.86 in MPF from October 1; many small entries each pay the $34.58 floor, so consolidating shipments into fewer entries saves fees either way. Check your broker's October invoices against these numbers.
Customs user fees rise 2.84 percent for fiscal year 2027 because inflation cleared the one percent trigger: the minimum merchandise processing fee becomes $34.58 and the maximum $670.86 per formal entry, while the 0.3464 percent rate itself does not change.

Antidumping duties on Chinese and Vietnamese walk-behind mowers revoked
Commerce (ITA) · Tariffs & customs · Effective Sep 8 · In forceEffective Sep 8In force5/5claims matched to the source
Who does this affect?
Importers and online sellers of gas-powered walk-behind mowers or mower sub-assemblies from China or Vietnam.
What it costs
A saving: no antidumping or countervailing deposits on entries made on or after July 13, 2026, and deposits already paid on those entries may be refundable through your broker.
Do this now
If you import these mowers, re-quote landed cost for shipments entered after July 13, 2026 without AD/CVD deposits, and ask your broker about deposits already paid on entries after that date. Separate duty orders on small vertical-shaft engines from China are not affected by this notice.
Commerce revoked the antidumping and countervailing duty orders on gas walk-behind lawn mowers from China and Vietnam because no U.S. producer asked to keep them. Entries on or after July 13, 2026 no longer owe AD/CVD deposits.

Nuvei pays $4.85M; FTC requires screening merchants by chargeback rate
FTC · Payments & fraud · Published Sep 4Published Sep 45/5claims matched to the source
Who does this affect?
Any seller opening a new merchant account, selling by telemarketing, or carrying elevated chargebacks.
What it costs
$4.85 million paid by Nuvei. Sellers with a prior termination or elevated chargebacks now face declined applications and reserve holds rather than fines.
Do this now
If a processor ever terminated you, disclose it when applying elsewhere; the order treats prior terminations as a red flag processors must catch. Track your chargeback ratio monthly and keep it far below one percent.
The FTC's second processor settlement in a week requires Nuvei to screen prospective merchants and investigate any client whose chargebacks exceed set limits. Expect tighter onboarding at every processor.

Commerce proposes 25 percent Section 232 duty on fire extinguishers, safes, and cables
Commerce Department, Industry and Security Bureau · Tariffs & customs · Deadline Aug 27 · PassedDeadline Aug 27Passed6/6claims matched to the source
Who does this affect?
Importers of fire extinguishers and fire-safety products, safes, electrical cables, musical instruments, welding-equipment parts, and trailers, and any brand whose product is mostly metal by weight, since this inclusion process now runs on a rolling basis.
What it costs
A proposed 25 percent Section 232 duty on the listed articles, 50 percent on filled steel containers applied to the container's value only, and 15 percent on agricultural trailers, on top of existing duties, if the inclusion is adopted.
Do this now
If any SKU is on the list (fire extinguishers, floor safes, conductor cables, brass instruments, welding parts, heat-exchanger parts, trailers), ask your broker to model a 25 percent Section 232 add-on now and watch the Federal Register for the inclusion notice; the same rolling process can reach any product that is mostly steel, aluminum, or copper, so check your top SKUs by weight.
The Bureau of Industry and Security proposed adding 14 derivative articles to the Section 232 steel, aluminum, and copper tariffs, including fire extinguishers, free-standing floor safes, electric conductor cables, brass-wind instruments, welding-machine parts, and trailers; most would pay 25 percent and filled steel gas containers 50 percent.

Do this now
If you sell children's loungewear, either make it tight-fitting under the sleepwear sizing rules or have the fabric flame-tested to 16 CFR 1615 and 1616. Loungewear that looks like pajamas is regulated as pajamas.

How a row earns its check mark

What it covers: Tariff proclamations and CBP guidance. Customs filing rules and fees. The documents Amazon suddenly asks for. Payment processor orders. Carrier price changes. Recalls in your category.
Source, not coverage: Every day we pull what the Federal Register, CBP’s CSMS messages, the FTC, and the CPSC actually published. No trade press, no commentary, no rumor from a thread.
Every claim matched: Each claim is tied to a sentence copied verbatim from the document. Software checks the match before publication and deletes any claim it cannot find. Open any change and tap “Source sentence” to see it.
Money is verified too: The cost line uses only figures the document itself gives, or one total shown with its arithmetic. No estimates of your exposure, no risk scores.
Ends with what to do: Who this affects and what to check in your store this week. Written by an operator, not a law firm.
