Each packer, swine contractor, live poultry dealer, stockyard owner, market agency, and dealer, upon proper request, shall give to the Secretary or his duly authorized representatives in writing or otherwise, and under oath or affirmation if requested by such representatives, any information concerning the business of the packer, swine contractor, live poultry dealer, stockyard owner, market agency, or dealer which may be required in order to carry out the provisions of the Act and regulations in this part within such reasonable time as may be specified in the request for such information.

Each stockyard owner, market agency, dealer, packer, swine contractor, and live poultry dealer, upon proper request, shall permit authorized representatives of the Secretary to enter its place of business during normal business hours and to examine records pertaining to its business subject to the Act, to make copies thereof and to inspect the facilities of such persons subject to the Act. Reasonable accommodations shall be made available to authorized representatives of the Secretary by the stockyard owner, market agency, dealer, packer, swine contractor, or live poultry dealer for such examination of records and inspection of facilities.

No agent or employee of the United States shall, without the consent of the stockyard owner, market agency, dealer, packer, swine contractor, or live poultry dealer concerned, divulge or make known in any manner, any facts or information regarding the business of such person acquired through any examination or inspection of the business or records of the stockyard owner, market agency, dealer, packer, swine contractor, or live poultry dealer, or through any information given by the stockyard owner, market agency, dealer, packer, swine contractor, or live poultry dealer pursuant to the Act and regulations, except to such other agents or employees of the United States as may be required to have such knowledge in the regular course of their official duties or except insofar as they may be directed by the Administrator or by a court of competent jurisdiction, or except as they may be otherwise required by law.

Every packer, live poultry dealer, stockyard owner, market agency, and dealer (except a packer buyer registered to purchase livestock for slaughter only) shall file annually with the Administration a report on prescribed forms not later than April 15 following the calendar year end or, if the records are kept on a fiscal year basis, not later than 90 days after the close of his fiscal year. The Administrator on good cause shown, or on his own motion, may grant a reasonable extension of the filing date or may waive the filing of such reports in particular cases.

No packer or dealer shall, in connection with the purchase of livestock in commerce, charge, demand, or collect from the seller of the livestock any compensation in the form of commission, yardage, or other service charge unless the charge is for services mandated by law or statute and is not inconsistent with the provisions of the Act.

(a) Each packer purchasing livestock on a carcass grade, carcass weight, or carcass grade and weight basis shall, prior to such purchase, make known to the seller, or to his duly authorized agent, the details of the purchase contract. Such details shall include, when applicable, expected date and place of slaughter, carcass price, condemnation terms, description of the carcass trim, grading to be used, accounting, and any special conditions.

(b) Each packer purchasing livestock on a carcass grade, carcass weight, or carcass grade and weight basis, shall maintain the identity of each seller's livestock and the carcasses therefrom and shall, after determination of the amount of the purchase price, transmit or deliver to the seller, or his duly authorized agent, a true written account of such purchase showing the number, weight, and price of the carcasses of each grade (identifying the grade) and of the ungraded carcasses, an explanation of any condemnations, and any other information affecting final accounting. Packers purchasing livestock on such a basis shall maintain sufficient records to substantiate the settlement of each transaction.

(c) When livestock are purchased by a packer on a carcass weight or carcass grade and weight basis, purchase and settlement therefor shall be on the basis of carcass price. This paragraph does not apply to purchases of livestock by a packer on a guaranteed yield basis.

(d) Settlement and final payment for livestock purchased by a packer on a carcass weight or carcass grade and weight basis shall be on actual hot weights. The hooks, rollers, gambrels or other similar equipment used at a packing establishment in connection with the weighing of carcasses of the same species of livestock shall be uniform in weight. The tare shall include only the weight of such equipment.

(e) Settlement and final payment for livestock purchased by a packer on a USDA carcass grade shall be on an official (final—not preliminary) grade. If settlement and final payment are based upon any grades other than official USDA grades, such other grades shall be set forth in detailed written specifications which shall be made available to the seller or his duly authorized agent. For purposes of settlement and final payment for livestock purchased on a grade or grade and weight basis, carcasses shall be final graded before the close of the second business day following the day the livestock are slaughtered.
