    Recordkeeping Requirements

    Daily Summary of Magazine Transactions (DSMTs) is a running balance of explosive materials in each magazine, and has the following requirements.

    • A complete inventory of your explosive materials is required annually. This inventory shall be entered into the DSMT for inspection purposes.

    • DSMTs must be maintained at each magazine or at a central location on the premises (a separate DSMT is required for each magazine).

    • The DSMT record should include:

      • The manufacturer’s name or brand name;

      • The date of receipt or removal;

      • The total quantity received in and removed from each magazine during the day; and

      • The total remaining on hand at the end of the day.

    • Entries of transactions SHALL be recorded no later than the close of the next business day.

    • Records must be retained for no less than 5 years from the transaction date.

    • When going out of business, records must be sent to the ATF Out of Business Records Center.

    • No entry is required for any day on which no explosive materials are placed into or removed from a magazine.

    Storage Variances

    Licensees or permittees who wish to use an alternate method or procedure, including alternate magazine construction standards, must submit a request for variance from the regulations. For additional information regarding variance requirements, see ATF’s Variance Request Guidelines.
