The popularity of Salada Teas in the U. S. led to the establishment of U. S. Headquarters and a blending and packaging plant in Boston, Massachusetts in 1917. Larkin constructed his new headquarters in the Back Bay area of Boston and commissioned the magnificent bronze doors that mark the entrance to the Salada Tea Building. The doors depict the early history of the tea trade as well as Larkin's commitment to quality. Over 12 feet tall and weighing more than two tons, the doors still stand proudly at 330 Stuart Street in Boston.

Salada first introduced its tea in tea bags in the 1930's to provide an easy way to brew a single cup of tea. Originally, the bags were made of fabric similar to gauze and were sewn closed. For convenient removal of the teabag, one end of a string was attached to the bag and the other to a paper tag, which remained outside the cup and could be grasped easily to avoid the hot steeping tea. To add an additional twist, Salada subsequently printed a few words of wit or wisdom on each tea tag beginning in the early 1960's. These tidbits were intended to provoke a smile or a thought while the tea drinker paused with a cup of Salada tea. Through the years, Salada tag lines have become a memorable part of Salada Tea, and tea drinkers still appreciate this feature today.
