1	Acute toxicity (Inhalation: Vapours)	Classification not possible	- -	-	-	No data.	FY2011	GHS Classification Guidance by the Japanese Government （July, 2010）
1	Acute toxicity (Inhalation: Dusts and mists)	Classification not possible	- -	-	-	No data.	FY2011	GHS Classification Guidance by the Japanese Government （July, 2010）
2	Skin corrosion/irritation	Classification not possible	- -	-	-	No data.	FY2011	GHS Classification Guidance by the Japanese Government （July, 2010）
3	Serious eye damage/eye irritation	Classification not possible	- -	-	-	No data.	FY2011	GHS Classification Guidance by the Japanese Government （July, 2010）
4	Respiratory sensitization	Classification not possible	- -	-	-	No data.	FY2011	GHS Classification Guidance by the Japanese Government （July, 2010）
4	Skin sensitization	Classification not possible	- -	-	-	No data.	FY2011	GHS Classification Guidance by the Japanese Government （July, 2010）
5	Germ cell mutagenicity	Classification not possible	- -	-	-	The classification is not possible due to no in vivo test data. Besides, a negative was reported in a bacterial reverse mutation test as an in vitro test (Evaluation of effect for the food safety (2004)).	FY2011	GHS Classification Guidance by the Japanese Government （July, 2010）
6	Carcinogenicity	Classification not possible	- -	-	-	No data.	FY2011	GHS Classification Guidance by the Japanese Government （July, 2010）
7	Reproductive toxicity	Classification not possible	- -	-	-	A test in which female rats were orally administrated from 7 days before cohabitation and throughout cohabitation, gestation, parturition, and a 4-day post-parturition period reported that "The only effects reported were reduced body-weight gain in dams at the two higher doses, accompanied by a statistically significant reduction in food consumption in those at the highest dose. No effects were observed in dams at the lowest dose or in offspring at any dose. The authors concluded that tetramethyl-pyrazine had no reproductive or developmental effects" (JECFA 1032 (2002)). But data on developmental effects in the offspring including teratogenicity are insufficient due to no fetal examination data at term pregnancy. In addition, there are no data on sexual function and fertility in male rats, therefore, it was classified as "Classification not possible."	FY2011	GHS Classification Guidance by the Japanese Government （July, 2010）
8	Specific target organ toxicity - Single exposure	Classification not possible	- -	-	-	No data.	FY2011	GHS Classification Guidance by the Japanese Government （July, 2010）
9	Specific target organ toxicity - Repeated exposure	Classification not possible	- -	-	-	A 90-day diet administration test given one dose (50 to 55 mg/kg/day) to rats reports that slight to moderate decrease in body-weight gain accompanied by statistically significant decreases in food use efficiency were observed only in females but no pathological lesions were found, and a NOEL was 50 to 55 mg/kg/day (JECFA 1032 (2002)). The dose is in a dose of a range of Guidance values, and effects near the upper limit of Guidance values (100 mg/kg/day) are unknown, therefore it was classified as "Classification not possible."	FY2011	GHS Classification Guidance by the Japanese Government （July, 2010）
10	Aspiration hazard	Classification not possible	- -	-	-	No data.	FY2011	GHS Classification Guidance by the Japanese Government （July, 2010）

NOTE:

GHS Classification Result by the Japanese Government is intended to provide a reference for preparing a GHS label or SDS for users. To include the same classification result in a label or SDS for Japan is NOT mandatory.
Users can cite or copy this classification result when preparing a GHS label or SDS. Please be aware, however, that the responsibility for a label or SDS prepared by citing or copying this classification result lies with users.
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.
