The Scopes of JIS C 0950
and J-Moss Green Mark Guideline
JIS C 0950 is the Japanese Industrial Standard
specifying the rules about “marking for presence”
of the specific chemical substances
for specific electrical and electronic equipment

What is marking for presence ?
3.1 “marking for presence” (JIS C 0950)
marking of content mark and presence condition of presence
places when the percentage content of the substance to be
calculated exceeds the reference value of percentage content inelectrical and electronic equipment
What are cases of exceeding the reference value of percentage content?
1”Cases of exceeding the reference value of percentage content” mean
① to ④ described below.

① There is no exempted application (i.e.JIS Annex B), and the content
exceeds the reference value.
･･･ Content mark (legal obligation)② There are exempted applications (= exceeding the reference value), andthe content exceeds the reference value in other portions as well.
･･･ Content mark (legal obligation)③ There are exempted applications (= below the reference value) Note, andthe content exceeds the reference value in other portions.
･･･ Content mark (legal obligation)④ There are exempted applications (= exceeding the reference value), andthe content is less or equal to the reference value in other portions.
･･･ J-Moss Green Mark (voluntary) Note
Note ③ The pattern of “There are exempted applications (= less or equal to the reference value)”
may be realized if technology further advances.

Note ④ Although the content exceeds the reference value in ④, it is not necessary to place a content
mark because this case falls under “Exemption from content mark (Annex B)” in JIS C 0950.
2The J-Moss Green Mark may be placed voluntarily according to the “J-Moss Green Mark Guideline.”Cases ① to ④ require “marking for presence”
because they are within the scope of JIS C 0950.
What is marking for presence?
3.1 “marking for presence” (JIS C 0950)
marking of content mark and presence condition of presence places
when the percentage content of the substance to be calculated exceeds thereference value of percentage content in electrical and electronic equipment
The rules about placing content mark and the presence condition are specified in
the following sections in JIS C 0950.
4 Marking for presence of specific chemical substances
5 Object of marking for presence
6 Method of marking
Note: Case ④ does not need to place a content mark but must “display the presence condition” on thewebsite and include its URL in catalogs based on Sections 4 to 6 in JIS C 0950.

Cases ⑤ and ⑥ shown below
do not exceed the “reference value of percentage content” anddo not need “marking for presence” as specified in JIS C 0950.
The J-Moss Green Mark can be placed voluntarily, according to the rules of the”J-Moss Green Mark Guideline.”⑤ There are exempted applications (= less or equal to the reference value),and the content is less or equal to the reference value in other portions
as well.
･･･ J-Moss Green Mark (voluntary) Note
⑥ There is no exempted application, and the content is less or equal to thereference value in all portions.
･･･ J-Moss Green Mark (voluntary)
Note ⑤ The pattern of “There are exempted applications (= less or equal to the reference value)”
may be realized if technology further advances.

The display of the presence condition on the website and the inclusionof its URL in catalogs are also voluntary.
