Hammill & Gillespie manufactures, imports, exports and supplies quality raw materials to a broad range of industry, following a tradition established by James Hammill in 1848. H&G represents the leading international manufacturers of clays, feldspars, silicas and carbonates, and we manufacture specialty mineral products to meet the most varied and demanding requirements of industry. We do not, however, carry USP or Food Grade products.

Hammill & Gillespie is headquartered in Livingston, NJ with a primary import/export terminal at Port Newark and with raw material and manufacturing sites throughout the country.
