Environmentally hazardous substance mark
The mark shall be in the form of a square set at an angle of 45° (diamond-shaped). The symbol (fish
and tree) shall be black on white or suitable contrasting background. The minimum dimensions shall
be 100 mm x 100 mm and the minimum width of the line forming the diamond shall be 2 mm. If the

Lithium battery mark
Packages containing lithium cells or batteries prepared in accordance with special provision 188 shall

The mark shall indicate the UN number preceded by the letters "UN", i.e. ‘UN 3090’ for lithium metal
cells or batteries or ‘UN 3480’ for lithium ion cells or batteries. Where the lithium cells or batteries
are contained in, or packed with, equipment, the UN number preceded by the letters "UN", i.e. ‘UN
3091’ or ‘UN 3481’ as appropriate shall be indicated. Where a package contains lithium cells or
batteries assigned to different UN numbers, all applicable UN numbers shall be indicated on one or
The mark shall be in the form of a rectangle with hatched edging. The dimensions shall be a minimum
of 120 mm wide x 110 mm high and the minimum width of the hatching shall be 5 mm. The symbol

metal batteries or cells) shall be black on white. The hatching shall be red. If the size of the package
so requires, the dimensions/line thickness may be reduced to not less than 105 mm wide x 74 mm

shall be legibly marked with package orientation arrows which are similar to the illustration shown
below or with those meeting the specifications of ISO 780:1997. The orientation arrows shall appear
on two opposite vertical sides of the package with the arrows pointing in the correct upright direction.
They shall be rectangular and of a size that is clearly visible commensurate with the size of the
package. Depicting a rectangular border around the arrows is optional.
Orientation arrows are not required on:
(a) Outer packagings containing pressure receptacles except cryogenic receptacles;
(b) Outer packagings containing dangerous goods in inner packagings each containing not more
than 120 ml, with sufficient absorbent material between the inner and outer packagings to
completely absorb the liquid contents;
(c) Outer packagings containing Class 6.2 infectious substances in primary receptacles each
containing not more than 50 ml;
(d) Type IP-2, type IP-3, type A, type B(U), type B(M) or type C packages containing Class 7
(e) Outer packagings containing articles which are leak-tight in all orientations (e.g. alcohol or
mercury in thermometers, aerosols, etc.); or
(f) Outer packagings containing dangerous goods in hermetically sealed inner packagings each

Labelling of packages
For each article or substance listed in Table A of Chapter 3.2, the labels shown in Column (5) shall be
affixed unless otherwise provided for by a special provision in Column (6).
