1	Acute toxicity (Inhalation: Dusts and mists)	Classification not possible	- -	-	-	No data available	FY2006	GHS Classification Manual （10 Feb, 2006）
2	Skin corrosion/irritation	Not classified	- -	-	-	From description that skin irritation was not admitted by the examination of the rabbit and the guinea pig (EHC, 129, 1992), and from description that there was no report of humans skin irritation (HSG (Health&Safety Guides), 61, World Health Organization/IPCS, 1991), it was carried out the outside of Category.	FY2006	GHS Classification Manual （10 Feb, 2006）
3	Serious eye damage/eye irritation	Category 2B	- Warning	H320	P305+P351+P338 P337+P313 P264	There were no results of an animal experiments. But it is believed that there is mild irritation due to the description "an eye may be stimulated"(HSG (Health&Safety Guides), 61, World Health Organization/IPCS, 1991). So it was classified into Category 2B.	FY2006	GHS Classification Manual （10 Feb, 2006）

7	Reproductive toxicity	Category 2	Warning	H361	P308+P313 P201 P202 P280 P405 P501	It was considered as Category 2 since in the study of the rat of EHC129 (1992) of Priority 1 document, reduction of the number of newborn and decline in a child's survival rate were seen at the dose in which toxicity (convulsion) is observed in the parental animals.

This GHS classification was conducted based on the information sources and the guidance for classification and judgement which are described in the GHS Classification Guidance for the Japanese Government etc. Using other literature, test results etc. as evidence and including different content from this classification result in a label or SDS are allowed.
Hazard statement and precautionary statement will show by hovering the mouse cursor over a code in the column of "Hazard statement" and "Precautionary statement," respectively. In the excel file, both the codes and statements are provided.
A blank or "-" in the column of "Classification" denotes that a classification for the hazard class was not conducted in the year.
An asterisk “*” in the column of “Classification” denotes that “Not classified (or No applicable)” and/or “Classification not possible” is applicable. Details are described in the column of “Rationale for the classification”. If no English translation is available for “Rationale for the classification,” please refer to the Japanese version of the results.
