Customs broker bond requirement: licensed brokers must maintain prescribed security and remain liable for losses from misfeasance or negligence. Licensed customs brokers must provide a statutory bond and prescribed security deposit obliging the broker and their successors to pay sums due to the Government arising from misfeasance or negligence by the broker or their employees; the Government may apply the deposited security to remedy short collections or unpaid charges, including after demands under the Customs Act, and the security is retained for a defined post-cessation retention period as additional protection for latent liabilities.
