Amazon is introducing one of the most important operational changes for Fulfilled by Merchant (FBM) sellers serving Amazon Business customers.
Starting September 30, 2026, Amazon will begin enforcing its Business Hour Delivery Rate (BHDR) requirement. Sellers that fail to maintain a 90% or higher BHDR could see their seller-fulfilled Amazon Business offers deactivated by October 30, 2026.
If your business ships directly to Amazon Business customers in the United States, United Kingdom, or Germany, this policy deserves your immediate attention. Unlike many performance metrics that affect visibility over time, BHDR can directly determine whether your products remain available to Business buyers.
In this guide, we'll explain exactly what the new rule means, why Amazon is enforcing it now, who is affected, and how you can prepare before enforcement begins.
Business Hour Delivery Rate (BHDR) measures the percentage of seller-fulfilled (FBM) orders that are delivered during the customer's stated business operating hours.
This is different from simply delivering a package on its promised date.
For example:
That order would negatively impact your Business Hour Delivery Rate.
Amazon has displayed BHDR as an informational metric for several years, allowing sellers to monitor performance without penalties. Beginning September 30, 2026, it becomes an enforceable performance requirement.

The timing isn't accidental.
Amazon continues investing heavily in the Amazon Business marketplace, which generated approximately $35 billion in annualized gross sales during 2025. With enterprise procurement becoming a major growth opportunity, Amazon is placing greater emphasis on reliable business deliveries.
Business buyers expect shipments to arrive when receiving departments are open—not simply by the promised delivery date.
Amazon's upcoming Amazon Business Reshape Conference in Nashville further highlights the company's expanding B2B strategy.
Alongside BHDR enforcement, Amazon has also introduced a pallet delivery option for eligible FBM Amazon Business shipments. Early pilot results showed that nearly 80% of participating business buyers selected pallet delivery, often preferring predictable receiving schedules over faster shipping.
Together, these initiatives demonstrate Amazon's broader objective:
Reliable business delivery is becoming just as important as fast delivery.
Not every Amazon seller needs to worry about BHDR.
The rule applies only if you:
The following sellers are not affected:
If your catalog includes both retail and Business customers, only your Business orders contribute to BHDR.
Amazon has outlined a phased enforcement process.
If your Business Hour Delivery Rate drops below the required threshold:
Importantly, this does not suspend your seller account.
Instead, your FBM offers become unavailable specifically to Amazon Business buyers until performance improves.
For sellers generating significant B2B revenue, that can translate into substantial lost sales.
Many FBM sellers rely on external shipping carriers.
Unlike FBA, where Amazon controls fulfillment and delivery timing, FBM sellers depend on carrier schedules, local delivery routes, weather conditions, and business receiving hours.
Even when shipments arrive on the promised date, deliveries made outside a customer's operating hours may still count against BHDR.
This makes operational planning more important than ever.
Businesses selling office supplies, industrial equipment, healthcare products, restaurant supplies, janitorial products, commercial electronics, and bulk inventory should pay particular attention, as Business customers often maintain strict receiving schedules.
The best time to improve BHDR is before enforcement begins.
Don't wait until September.
Review your Business Hour Delivery Rate now and identify any downward trends before they become enforcement issues.
Different carriers perform differently depending on destination and delivery windows.
Look for:
Small improvements in carrier selection can significantly improve BHDR.
If certain products receive a large percentage of Amazon Business orders, moving them to Fulfillment by Amazon (FBA) may reduce operational risk.
While FBA introduces storage and fulfillment fees, it also removes the burden of managing delivery timing for Business customers.
Compare:
For many high-volume SKUs, FBA may become the more cost-effective long-term option.
If you sell bulk products or large commercial orders, Amazon's new pallet delivery option could improve the customer experience while aligning with Business buyer preferences.
Early adoption may provide operational advantages as Amazon expands the program.
To consistently remain above the 90% threshold:
Proactive monitoring is far easier than recovering after enforcement begins.
Amazon's Business Hour Delivery Rate policy represents another step toward creating a more dependable B2B marketplace.
While the rule affects only a subset of sellers today, it signals Amazon's increasing focus on operational excellence—not just competitive pricing.
For FBM sellers serving Business customers, maintaining a 90% BHDR should become part of your standard performance monitoring well before September 30, 2026.
Preparing now gives you time to optimize carriers, adjust fulfillment strategies, and evaluate whether certain Business products are better suited for FBA.
Waiting until enforcement begins could mean scrambling to recover lost Business visibility.
No. Business Hour Delivery Rate only applies to seller-fulfilled (FBM) orders shipped to Amazon Business customers. FBA orders are not included.
Amazon will first notify you and provide recommendations for improvement. If your BHDR remains below 90% after the improvement period, your seller-fulfilled offers for Amazon Business customers may be deactivated beginning October 30, 2026.
The initial rollout applies to sellers serving Amazon Business customers in the United States, United Kingdom, and Germany.
Amazon evaluates BHDR using a rolling 14-day measurement window, meaning your performance is continuously updated based on recent deliveries.
Operational policy changes can impact profitability just as much as advertising costs. Understanding whether to improve your FBM workflow, switch specific SKUs to FBA, or optimize your shipping strategy requires a careful review of your data.
