(i)either the concentration specified in the approved supply list for the substance or substances under consideration, or
(ii)the concentration specified in paragraph 4 of Part II of this Schedule (Table IV or Table IVA in the case of gases) where the substance or substances do not appear in the approved supply list or appear in it without concentration limits;

PXi.R38 the percentage by weight of each irritant substance to which is assigned the risk phrase R38 in the preparation,
LXi.R38 the irritant (R38) limit specified for each corrosive or irritant substance expressed as a percentage by weight to which is assigned the risk phrase R35, R34 or R38 in the preparation;
(c)owing to their sensitizing effects by skin contact preparations containing at least one substance dangerous for supply to which is assigned phrase R43 (may cause sensitization by skin contact) that produces such effects in individual concentrations exceeding:
either the concentration specified in the approved supply list for the substance under consideration, or
the concentration specified in paragraph 5 of Part II of this Schedule (Table V or Table VA) where the substance or substances do not appear in the approved supply list or appear in it without concentration limits.
