SUGARS, SIRUPS, AND MOLASSES

GENERAL INSTRUCTIONS ·

Art. 673. Duties of customs officers.-(a) All customs officers and employees having duties to perform in connection with the treatment of imported sugars, sirups, and molasses are hereby instructed to use the utmost care and vigilance to insure that the work of weighing, gauging, sampling, classifying, and testing is accurately and efficiently performed.

(b) Each inspector, weighing officer, gauging officer, and sampler shall be furnished with a copy of the regulations relative to sugars, sirups, and molasses. The appraiser shall notify the collector of the boundaries of sugar districts and the location of the examiner's or sampler's office in each district, and such information shall be furnished by the collector to the inspectors and weighing officers. The examiners and samplers in charge shall be held responsible by the appraiser for the strict and impartial enforcement of these regulations, and to this end they shall be notified relative to the time of

discharge and weighing of sugar and molasses cargoes in their respective districts by the inspector or weigher in charge of the same.

(c) Duties of inspector.-Inspectors are directed to exercise a personal supervision over the discharging of sugar cargoes. They shall have their permits indorsed by the examiner or sampler in charge after the samples have been obtained in accordance with these regulations. Dock sweepings shall be gathered up and weighed and sampled when discharging has stopped for any cause. The inspector is directed to keep, in every instance, an accurate account of the kind and number of packages of sweepings, which he shall indorse on the back of the permit or lighter manifest before it is presented to the appraiser's office for indorsement. If no sweepings are found, the inspector shall indorse the permit or manifest accordingly.

(d) Duties of weighing officers.-The weighers shall do the actual weighing and recording of the results, and shall not permit any other person to handle the scales. They shall be required to exercise a strict scrutiny of the conditions under which the weighing is being done, shall keep the scales clean of all foreign accretion, to the end that atmospheric and other exterior influence inimical to accuracy may be avoided, and to obviate the possibility of any drafts passing over the scales unweighed or being reweighed. Scales with beam indicating 1 pound are to be employed in weighing sugar wherever possible.

Art. 674. Separation of shipments.--When an importation is consigned to two or more consignees, each consignee's merchandise shall be treated as a separate importation, provided separate entry is made therefor.

Art. 675. Time of weighing and sampling.-All sugars and sugar products requiring either weighing or sampling shall have those operations performed at the time of unlading. Merchandise requiring both weighing and sampling shall have those operations performed simultaneously whether discharged under either a regular or a special permit.

Art. 676. Absorption of sea water.-Inasmuch as the absorption of sea water or moisture reduces the polariscopic test of sugar, there shall be no allowance on account of increased weight of sugar importations due to unusual absorption of sea water or of moisture while on the voyage of importation. That portion of the cargo claimed by the importer to have absorbed sea water or

T. D. 39463.

moisture on the voyage of importation shall be weighed, sampled, classified, and tested separately. This claim must be made at the time of weighing. Special care must be taken that such sugars are sampled so as to represent the contents of the packages.

Art. 677. Molasses not for human consumption.-When molasses is not imported to be used commercially for the extraction of sugar or for human consumption, a declaration to that effect and identifying the invoice covering such molasses shall be filed by the importer with the collector.

Art. 678. Filing of affidavit for molasses in tank cars.— When an importation of molasses is shipped in tank cars the importer shall file with the collector an affidavit showing whether there is any essential difference either in total sugars or character of the molasses in the different cars. A composite sample shall be made by the examiner to represent the importation. When, in the opinion of the appraiser, the molasses in any of the cars is not identical with that in the other cars, such cars shall be gauged, sampled, classified, and tested separately.

Art. 679. Expense of unlading.-No expense incidental to the unlading, transporting, sorting, or arranging of sugars and molasses for the convenient weighing, gauging, measuring, sampling, or marking thereof shall be borne by the Government. When weighing, gauging, sampling, or measuring is performed concurrently with the unlading, or while the merchandise is being transported from the vessel's side to the importer's premises, no part of the expense of the transportation or handling of the merchandise shall be borne by the Government.

Art.680. Standardization of weights and measures.In the carrying out of these regulations, all weights and measures shall fully comply with the standards established for such weights and measures by the National Bureau of Standards.

Art. 681. Mixing classes of sugar.-No regulations relative to the weighing, taring, sampling, classifying, and testing of imported sugars shall be so construed as to permit of mixing together sugars of different classes, such as centrifugal, beet, molasses, or any sugar different in character from those mentioned, for the purpose of weighing, taring, sampling, classifying, or testing.
