A new round of reciprocal tariff rates took effect Saturday, August 1, 2026, and unlike several earlier deadlines in this trade cycle, it came and went without a delay. Commerce officials confirmed ahead of time that there would be no extension and no grace period. For small business importers, the cost is now landing on entries clearing customs this week.
What happened
The administration set country-specific reciprocal rates by letter, layered on top of the roughly 10% baseline tariff applied to most imports. Among the rates now in force, as reported by Under30CEO: Japan at 25%, South Korea at 25%, Indonesia at 32%, and Thailand and Cambodia at 36%. Steel and aluminum remain at 50%. Canadian and Mexican goods that don’t qualify under USMCA remain at 25%.
The scale of the small-business exposure is the part that gets underplayed. The Commerce Department reports that 97% of U.S. businesses that import are small businesses — meaning the pressure from this round falls mostly on firms without a trade-compliance department or the balance sheet to absorb a cost shock.
The Center for American Progress estimates tariffs cost small-business importers an average of $306,000 in the first year, and projects that if current monthly tariff levels hold through 2026, the typical small business will pay more than $500,000 in tariffs next year.
There’s a second, quieter cost. With the $800 de minimis exemption gone since August 2025, every inbound shipment now requires a formal customs entry — adding brokerage fees, paperwork and processing time to shipments that used to clear with almost none of it.

Why it matters
Small importers spent the first half of 2026 finally seeing profitability tick back up. This round arrives on top of that recovery, not instead of it — and it arrives right as fall and holiday inventory is being ordered and paid for.
The cash-flow shape of a tariff is what makes it hurt more than the headline rate suggests. Duty is owed at entry, before the goods are sold and often months before the receivable is collected. A 25% or 32% rate doesn’t just compress margin; it pulls working capital forward into the exact stretch of the year when seasonal businesses are already at their thinnest.
And there’s no gradual phase-in to plan around. The rates applied to goods entered on August 1.
What this means for small business owners
Reprice from landed cost, not invoice cost. If your pricing still keys off the supplier invoice, it’s wrong. Landed cost is invoice plus duty plus freight plus brokerage plus formal-entry fees. Rebuild it per SKU for anything sourced from an affected country, and do it before you quote fall orders.
Get duty out of a single lump expense account. Booking all of it to “Cost of Goods Sold” or a catch-all “freight and duties” line tells you nothing you can act on. Separate duty and tariff charges by country or supplier so you can see which sourcing relationships are actually underwater and which are fine.
Check the country of origin, not the shipping address. Rates are set by origin. Goods routed through a third country still carry the origin country’s rate, and getting this wrong on an entry creates a liability, not a saving.
Model the cash gap, not just the margin hit. Duty paid in August on goods that sell in November and collect in December is a three-to-four-month hole. Map it on a 13-week cash flow so you find out now whether you need a line of credit, rather than in October.
Budget the de minimis change separately. If you’re an e-commerce seller who used to ship small parcels under the old $800 threshold, formal entry on every shipment is a per-shipment administrative cost. On high-volume, low-value orders that can matter more than the duty rate itself.
Keep clean documentation. Origin records, classification support and entry paperwork are what let you claim a refund, challenge a classification, or survive a customs review later. As Under30CEO put it, clean documentation is quietly becoming a competitive advantage.
The bottom line
These rates are live and they’re not scheduled to phase out. The businesses that come through the next two quarters intact will be the ones that reprice off real landed cost, track duty at a granular enough level to see where it’s actually coming from, and plan the cash timing around it. That work is a bookkeeping exercise before it’s a strategy exercise — and it’s easier to do in August than in November.
