The item must be mercury-free for use on submarines/surface ships, with strict contamination prohibitions. Offers will be evaluated using Lowest Price Technically Acceptable (LPTA) criteria, and consideration for award is limited to authorized distributors of the original manufacturer, who must provide proof of authorization.
