Goods of Class 4.2

The total mass carried in a bulk container shall be such that its spontaneous ignition temperature is
greater than 55 °C.

Goods of Class 4.3

These goods shall be carried in bulk containers which are waterproof.

Goods of Class 5.1

Bulk containers shall be so constructed or adapted that the goods cannot come into contact with wood
or any other incompatible material.

Goods of Class 6.2

Animal material containing infectious substances (UN Nos. 2814, 2900 and 3373) is authorized for
carriage in bulk containers provided the following conditions are met:
(a) Sheeted bulk containers BK1 are permitted provided that they are not filled to maximum
capacity to avoid substances coming into contact with the sheeting. Closed bulk containers
BK2 are also permitted;
(b) Closed and sheeted bulk containers, and their openings, shall be leak-proof by design or by the
fitting of a suitable liner;
(c) The animal material shall be thoroughly treated with an appropriate disinfectant before
loading prior to carriage;
(d) Sheeted bulk containers shall be covered by an additional top liner weighted down by
absorbent material treated with an appropriate disinfectant;
(e) Closed or sheeted bulk containers shall not be re-used until after they have been thoroughly
cleaned and disinfected.
NOTE: Additional provisions may be required by appropriate national health authorities.

Wastes of Class 6.2 (UN 3291)

(a) (Reserved);
(b) Closed bulk containers and their openings shall be leakproof by design. These bulk containers
shall have non porous interior surfaces and shall be free from cracks or other features which
could damage packagings inside, impede disinfection or permit inadvertent release;
(c) Wastes of UN No. 3291 shall be contained within the closed bulk container in UN type tested
and approved sealed leakproof plastics bags tested for solids of packing group II and marked in
accordance with Such plastics bags shall be capable of passing the tests for tear and
impact resistance according to ISO 7765-1:1988 "Plastics film and sheeting - Determination of
impact resistance by the free-falling dart method - Part 1: Staircase methods" and ISO 6383-
2:1983 "Plastics - Film and sheeting - Determination of tear resistance. Part 2: Elmendorf
method". Each bag shall have an impact resistance of at least 165 g and a tear resistance of at
least 480 g in both parallel and perpendicular planes with respect to the length of the bag. The
maximum net mass of each plastics bag shall be 30 kg;
(d) Single articles exceeding 30 kg such as soiled mattresses may be carried without the need for a
plastics bag when authorized by the competent authority;
(e) Wastes of UN No. 3291 which contain liquids shall only be carried in plastics bags containing
sufficient absorbent material to absorb the entire amount of liquid without it spilling in the bulk
(f) Wastes of UN No. 3291 containing sharp objects shall only be carried in UN type tested and
approved rigid packagings meeting the provisions of packing instructions P621, IBC620 or
(g) Rigid packagings specified in packing instructions P621, IBC620 or LP621 may also be used.
They shall be properly secured to prevent damage during normal conditions of carriage. Wastes
carried in rigid packagings and plastics bags together in the same closed bulk container shall be
adequately segregated from each other, e.g. by suitable rigid barriers or dividers, mesh nets or
otherwise securing, such that they prevent damage to the packagings during normal conditions
of carriage;
(h) Wastes of UN No. 3291 in plastics bags shall not be compressed in a closed bulk container in
such a way that bags may be rendered no longer leakproof;
(i) The closed bulk container shall be inspected for leakage or spillage after each journey. If any
wastes of UN No. 3291 have leaked or been spilled in the closed bulk container, it shall not be
re-used until after it has been thoroughly cleaned and, if necessary, disinfected or
decontaminated with an appropriate agent. No other goods shall be carried together with UN
No. 3291 other than medical or veterinary wastes. Any such other wastes carried in the same
closed bulk container shall be inspected for possible contamination.


Material of Class 7

For the carriage of unpackaged radioactive material, see

Goods of Class 8

These goods shall be carried in bulk containers which are watertight.

Goods of Class 9

For UN 3509, only closed bulk containers (code BK2) may be used. Bulk containers shall be made
leak tight or fitted with a leak tight and puncture resistant sealed liner or bag, and shall have a 
means of retaining any free liquid that might escape during carriage, e.g. absorbent material. 
Packagings, discarded, empty, uncleaned with residues of Class 5.1 shall be carried in bulk 
containers which have been so constructed or adapted that the goods cannot come into contact with 
wood or any other
combustible material.

Use of flexible bulk containers

Before a flexible bulk container is filled it shall be visually examined to ensure it is structurally
serviceable, its textile slings, load-bearing structure straps, body fabric, lock device parts including
metal and textile parts are free from protrusions or damage and that inner liners are free from rips, tears
or any damage.

For flexible bulk containers, the period of use permitted for the carriage of dangerous goods shall be
two years from the date of manufacture of the flexible bulk container.

A venting device shall be fitted if a dangerous accumulation of gases may develop within the flexible
bulk container. The vent shall be so designed that the penetration of foreign substances or ingress of
water is prevented under normal conditions of carriage.

Flexible bulk containers shall be filled in such a way that when loaded the ratio of height to width does
not exceed 1.1. The maximum gross mass of the flexible bulk containers shall not exceed 14 tonnes.
