A clean bill of lading is a bill of lading without any restrictive clauses. It will only be delivered if the quantity of the goods is correct and if they are in apparent good order and condition and loaded under deck. If, during the loading of the cargo, the apparent good order and condition or the quantity, is different with the particulars given on the shipping permit, measurement slip, and mate's receipt, remarks will be entered by the head tallyman on the shipping permit and the measurement slip and by officer, responsible for the loading of the goods on board, on the mate's receipt (e.g. 5 bags less in dispute, 7 bars rusty, etc.). Later, these remarks, called restrictive clauses, will be copied on the bill of lading.
Consequently, a clean bill of lading is a bill of lading stating: "Shipped on board in apparent good order and condition" , without handwritten or stamped remarks (called restrictive clauses).
From Rule 34a of the U.R it follows that remarks or clauses which do not refer to the quantity or the state of the goods, do not make the bill of lading "foul". The following clauses: "Carrier's liability ceases on transshipment in paper bags - carrier's rights reserved" or "Second hand drums" , or "Weak strapping" , etc. don't make the bill of lading "foul".
