Amazon’s “Fulfillment by Amazon” (FBA) program, through which it provides warehousing and shipment services for products from third-party sellers, was well as its larger vendor shipment services are being partially suspended through April 5 due to the global coronavirus outbreak. This suspension will allow Amazon to prioritize shipment of “household staples, medical supplies and other high-demand products” the company said in a support document on its website, and confirmed to TechCrunch in an email.

The commerce giant notes in the email that it is “seeing increased online shopping” in the wake of the COVID-19 pandemic, and will focus on prioritizing the reception, restocking and delivery of the essential products that are most in demand from this new uptick in activity from Amazon shoppers. For all other products, Amazon says it has disabled the creation of new inbound shipments for FBA members, as well as for retail vendors (their business-to-business selling platform).
