Customs broker security bond ensures deposit may be used to satisfy government claims for negligence or misfeasance. A customs broker bond obliges the broker to provide a security deposit guaranteeing faithful conduct and payment of any sums due to the Government resulting from the broker's or employees' misfeasance or negligence; the Government may apply the deposit to satisfy such liabilities. The bond remains effective for a fixed period after the broker ceases to act, permitting application of the deposit to liabilities discovered after cessation, and authorizes Commissioner-level acceptance on behalf of the President.
