Sinomax USA is closing its Phoenix-area manufacturing operation and plans to lay off 89 workers as production is shifted to other facilities. The company expects its Valley operations to wind down by late April, cutting a local production foothold and moving that manufacturing capacity out of Arizona.

State WARN filing lists 89 job cuts

A Worker Adjustment and Retraining Notification filing with the state lists 89 employees as affected, with the notice dated March 26. According to AZ Job Connection, the notice appears under the name Sinomax East, Inc. and serves as the formal trigger for local rapid-response services aimed at the workers who are losing their jobs.

Company cites regulatory hurdles and shifting demand

As reported by the Phoenix Business Journal, Sinomax pointed to local regulatory hurdles and shifting product demand as reasons behind the move. The company told the Business Journal it plans to consolidate U.S. production in Tennessee and "will cease manufacturing operations by late April."

Support for affected workers

Workers covered by the WARN filing can access reemployment assistance through ARIZONA@WORK and Maricopa County business and workforce teams. These groups typically organize rapid-response events that can include resume workshops, job fairs, training referrals and guidance on unemployment insurance, coordinating with employers and state officials to help displaced employees land on their feet.

Sinomax's U.S. footprint and context

Industry coverage notes that Sinomax maintains manufacturing and distribution capacity in the Nashville and La Vergne, Tennessee, area in addition to its Phoenix-region operations. That existing Tennessee hub makes it a logical consolidation point for U.S. output. Centralizing work there could reduce costs for the company, although it also means shifting jobs and production work out of the Valley.

Legal note: WARN basics

State WARN filings are the official mechanism used to notify workers and local agencies of plant closings or mass layoffs. Under the federal WARN Act, employers generally must provide 60 days of advance notice in those situations, although there are some narrow exceptions. The U.S. Department of Labor offers guidance on how those rules apply.
