Newport Beach-based American Vanguard Corp. has launched a new Netherlands unit as part of a restructuring of its subsidiary Amvac Chemical Corp. and in preparation for Alfredo Pelaez’s retirement as Amvac’s director of international sales.

Pelaez plans to retire in the first quarter of next year, according to the company.

The specialty chemical maker has named agriculture industry veteran Ad de Jong as managing director of the new subsidiary, Amvac Netherlands BV. De Jong will lead all sales, marketing, finance and registration of Amvac products to international markets.

He joined Amvac from Middlebury, Conn.-based chemicals manufacturing company Chemtura Corp., where he spent 23 years in various roles, including vice president of crop protection for Europe, Middle East, Africa and Asia Pacific. He also spent time as chairman of Chemtura’s European business council.

Pelaez has been at Amvac since 2001 overseeing international sales, which have grown tenfold during the period, according to the company.

Amvac’s parent company ended the first quarter with $87.3 million in revenue, up 32% from the year-earlier quarter. It had $8.7 million in net income, a 74% jump.
