Tariff Impact on Accounts Payable: Why Importers Are Losing Control of AP

Tariff impact on accounts payable is the operational strain that hits when changing import duties knock invoice values, GL coding, and approval workflows out of sync with purchase orders and budgets. Businesses importing goods will see strain regardless of the decisions made surrounding tariffs. The 10% Section 122 import surcharge expired by law at midnight on July 24, 2026, and the replacement has arrived exactly as expected: not a return to flat-rate simplicity, but a country- and product-specific framework that's arguably harder for AP teams to manage. This article looks at why tariff volatility hits accounts payable harder than almost any other finance function, and what AP automation actually does to bring it back under control.

 Key Takeaways 

• The Section 122 tariff surcharge expired July 24, 2026. It has been replaced by Section 301 tariffs on 60 economies, ranging from 10% to 12.5%, with no statutory expiration date.
• Tariff volatility causes invoice-to-PO mismatches, duty miscoding, refund reconciliation backlogs, and approval bottlenecks in AP.
• Manual AP processes can't absorb frequent rate changes. The exception volume just compounds every cycle.
• AP automation gives finance leaders real-time visibility into landed cost, GL coding accuracy, and cash flow, whatever tariff framework is in place.
• Businesses that automate AP now will be in a much stronger position to handle the Section 301 regime and whatever changes follow it.

What Is Happening With US Tariffs in 2026? 

he Section 122 import surcharge was always a stopgap. Introduced after the Supreme Court struck down the earlier IEEPA tariffs in February 2026, it ran for a fixed 150-day period that ended by statute at 12:01 a.m. ET on July 24, 2026. Only Congress could have extended it, and no extension legislation was ever introduced.

On July 23, the day before expiry, USTR made the shift official. Ambassador Jamieson Greer announced final Section 301 tariffs on 60 economies, the outcome of a forced-labor investigation that concluded every reviewed economy, accounting for roughly 99% of US import volume, had failed to adequately enforce bans on goods made with forced labor. The new rates took effect alongside Section 122's expiry: 10% for roughly 15 trading partners, and 12.5% for around 45 others, replacing the flat 10% surcharge with a country-by-country structure. A separate 25% tariff on most Brazilian goods took effect July 22. EU goods had already moved to a 15% all-inclusive ceiling on July 1, and USMCA-qualifying goods from Canada and Mexico remain at zero. A second Section 301 investigation into excess industrial capacity, covering 16 economies, is still pending and could add further country-specific duties later this year, alongside separate Section 232 investigations into pharmaceuticals and medical devices.

The practical difference for finance teams is significant. Section 122 was one flat number applied almost universally. Section 301 has no rate cap and no built-in expiration, and it now applies dozens of different rates depending on country of origin, with separate exemptions for agricultural goods, aviation parts, minerals, and goods already covered by Section 232. That's no longer a hypothetical planning question, it's the live environment AP teams are now operating in.

The question for most finance teams was never really whether rates would go up or down after July 24. It was whether their AP setup could handle the shift from one flat national rate to dozens of country- and product-specific rates, each capable of changing on its own timeline. That structural shift, now in effect, is what determines whether AP stays in control from here.

How Tariff Volatility Disrupts Accounts Payable 

Tariff changes tend to get discussed as a procurement or pricing issue. In practice, the operational burden lands on accounts payable, and it repeats every processing cycle until the underlying process changes.

Invoice Values Stop Matching Purchase Orders

When a shipment lands after a rate change, or gets reclassified under a new HTS code, the landed cost on the invoice no longer matches the original PO or budget. That triggers a manual investigation on every affected line.

Duty and Surcharge Coding Becomes a Moving Target

Section 122, Section 232, and Section 301 duties interact differently, and some stack while others don't. Get the GL coding wrong and it's not just a reporting headache, it distorts true margin visibility across every import-heavy product line.

Refund and Reconciliation Work Piles Up

CBP is now processing tariff refund claims through its ACE Portal, which means AP and trade compliance teams are chasing historical refunds alongside current invoices. It's a second workstream most AP functions were never resourced to handle.

Approval Workflows Can't Keep Pace

When landed costs shift week to week, static approval thresholds and PO-matching rules start to break down. More invoices end up in manual exception queues, right when the team can least afford the bottleneck.

Forecasting and Cash Flow Planning Lose Reliability

CFOs need a current, accurate view of committed and incoming payables to model cash impact properly. If AP data is delayed, miscoded, or stuck in spreadsheets, that visibility disappears just when leadership needs it most.

According to Ardent Partners, organizations with automated AP processes absorb rising invoice volume and cost pressure with far less added headcount than those still relying on manual processing. That gap only widens during periods of input-cost volatility, like the one AP teams are heading into now.

Manual AP vs. Automated AP During Tariff Volatility

Best Practices for Managing AP Through Tariff Uncertainty

• Centralize invoice capture so every invoice, whatever its format or supplier, lands in one system instead of scattered across inboxes and shared drives.
• Standardize duty and tariff GL coding so Section 122, 232, and 301 charges are classified consistently and reportable by country of origin and HTS code.
• Automate PO and landed-cost matching so rate changes get flagged immediately instead of turning up during month-end close.
• Build configurable, volume-flexible approval workflows so a spike in exceptions doesn't turn into late payments or lost early-payment discounts.
• Maintain real-time payables visibility so finance leadership can model cash flow scenarios as tariff policy shifts, rather than waiting on period-end reports.

How Kefron AP Brings Stability Back to Accounts Payable

Kefron AP replaces manual, spreadsheet-driven invoice processing with automated capture, intelligent coding, and configurable approval workflows that adapt as your cost structure changes. Not once a quarter, but as often as trade policy demands.

• Invoices are captured and matched automatically, so a shifted landed cost gets flagged for review instantly instead of surfacing weeks later.
• Duty and tariff-related GL coding is standardized and auditable, giving finance a reliable view of true cost by product line and country of origin.
• Approval workflows scale with volume and complexity, so exception spikes don't turn into payment delays.
• Full visibility into payables status gives finance leaders the real-time data they need to forecast cash flow with confidence, even while trade policy is still in flux.

Whatever framework ends up replacing Section 122, whether rates fall, hold steady, or expand into new product categories, the businesses best placed to absorb the change will be the ones whose AP function isn't held together by manual patches.

Frequently Asked Questions

What is the tariff impact on accounts payable? Tariff changes alter landed cost after a PO has already been issued. That causes invoice mismatches, incorrect duty coding, and approval delays in AP, unless the process is automated to catch these changes in real time.

When does the current US tariff surcharge expire? The Section 122 import surcharge expires July 24, 2026, by statute, unless Congress extends it.

Will tariffs be removed after July 24, 2026? It's unlikely. The most probable outcome is a shift to Section 301 and Section 232 authorities, which typically produce country- and product-specific rates rather than one flat tariff.

How does AP automation help with tariff volatility? It standardizes duty coding, flags invoice-to-PO mismatches automatically, scales approval workflows during exception spikes, and gives finance leaders real-time visibility into payables. All of that matters most when tariff rates are changing frequently.

How long does it take to implement Kefron AP? Timelines vary depending on business size and integration complexity. A consultation is the fastest way to get a specific estimate for your organization.
