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 current 10% Section 122 import surcharge expires by law on July 24, 2026, and whatever replaces it is expected to bring country- and product-specific rates instead of one flat number. 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 expires July 24, 2026. It's likely to be replaced by a more complex, country-specific tariff framework, not eliminated.
  
  
• 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 for whatever replaces Section 122 after July 24.

What Is Happening With US Tariffs in 2026? 

The Section 122 import surcharge is a temporary 10% tariff introduced after the Supreme Court struck down the earlier IEEPA tariffs in February 2026. It runs for a fixed 150-day period, and by statute that period ends on July 24, 2026. Only Congress can extend it. Markets expect the administration to announce its next move before that deadline, most likely sometime between July 15 and July 24.

The most likely outcome isn't a return to tariff-free trade. Instead, the administration looks set to lean on Section 301 and Section 232 authorities, which allow for country-specific and product-specific tariffs rather than one universal rate. USTR has already proposed tariffs in the 10 to 12.5% range on countries that together account for the large majority of US imports, tied to a Section 301 forced-labor investigation, plus a proposed 25% tariff on most goods from Brazil. Separate Section 232 investigations into pharmaceuticals and medical devices could add further tariffs later this year.

Most finance teams are focused on whether rates go up or down after July 24. The bigger question is whether their AP setup can 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, not the headline rate, is what really determines whether AP stays in control.

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.
