LI firm expands to build Sephora displays for inside 850 Kohl’s stores

A Melville manufacturer of store displays used in selling cosmetics, perfume and skin care products is expanding to construct at least 850 Sephora shops inside Kohl’s department stores nationwide, officials said.

D3 LLC plans to rent 18,840 square feet of additional space at 70 Maxess Rd., where it already uses 36,530 square feet to design and produce cosmetics displays for airports and cruise ships.

The company also plans to make improvements to 20 Melville Park Rd., its headquarters and manufacturing hub for displays found in Sephora stores, and 75 Marcus Dr., where displays are made for Macy’s, Bloomingdale’s and other department store chains.

The expansion is expected to cost $3 million and add 65 jobs to D3’s workforce, which averages 191 people, according to its application for tax breaks from the Suffolk County Industrial Development Agency.

Last month, the IDA board voted unanimously to grant $980,000 in tax aid to the company, including $935,550 off property taxes over 10 years, or a 27.5% savings.
