NEW YORK (Reuters) – Amazon.com Inc (AMZN.O) is suspending sellers from sending non-essential products to its U.S. and U.K. warehouses until April 5 in the latest move to free up inventory space for much-needed supplies that are in shortage as a result of the coronavirus outbreak.

In a note sent to sellers on Tuesday, Amazon said it is seeing increasing online shopping demand from consumers. As its household staples and medical supplies are running out of stock, it will prioritize certain categories in order to “quickly receive, restock, and ship these products to customers.”

Amazon defined five categories as essential products that can continue shipping, including Baby Product, Health & Household, Beauty & Personal Care, Grocery, Industrial & Scientific, Pet Supplies.

The move follows Amazon’s announcement it will hire 100,000 workers for its warehouses on Monday, as the Seattle-based giant is trying to meet growing online shopping need from people who stay home amid the coronavirus outbreak.

Third-party sellers account for over half of the sales on Amazon. Amazon has been courting sellers to use its own fulfillment system, enabling many of them with faster delivery without the risks of sitting on inventories.

It is especially popular for sellers who use a dropping shipping method, meaning sellers import products from manufacturers in countries including China and directly send them to an Amazon warehouse. Amazon earns fees from managing the storage and delivery process.

Sellers supplying products that are deemed non-essential could see their products run out of stock and they will be unable to restock as a result of the measure. Still, they can use other fulfillment methods to directly mail products to customers.

Amazon did not immediately replied to request for comment.
