(a) Each first handler and each exporter responsible for the collection of assessments under this subpart shall remit assessments to the Board by the 15th day of the month following the month in which the lambs were purchased for slaughter or export, as required by regulations recommended by the Board and prescribed by the Secretary, has provided otherwise; or

(b) If a first handler marketed lambs or lamb products directly to consumers, assessments shall be remitted to the Board by the 15th day of the month following the month in which the lambs or lamb products were marketed, as required by regulations recommended by the Board and prescribed by the Secretary, has provided otherwise.

(c) Late payment charges. Any unpaid assessments due to the Board pursuant to §1280.217 shall be increased 2 percent each month beginning with the day following the date such assessments were due. Any remaining amount due, which shall include any unpaid charges previously made pursuant to this paragraph, shall be increased at the same rate on the corresponding day of each month thereafter until paid. For the purposes of this paragraph, any assessment determined at a date later than the date prescribed by this subpart, because of a person's failure to timely submit a report to the Board, shall be considered to have been payable by the date it would have been due if the report had been timely filed. The timeliness of a payment to the Board shall be based on the applicable postmark date or the date actually received by the Board, whichever is earlier.

(d) Persons failing to remit total assessments due in a timely manner may also be subject to actions under Federal debt collection procedures.
