(b) Investigation format for chemical substances included in products
A Gree’Net provides flexible support for formats of controlling chemical substances included in
products, that are widely adopted in the industrial world, primarily considering usability forsuppliers.
The following formats can be used to input information to A Gree’Net:・ chemSHERPA-CI・ chemSHERPA-AI
・ JAMP AIS #1（2018/7～）

JAMP: Joint Article Management Promotion consortium: https://chemsherpa.net/english/jamp/about
AIS: Information transmission format for chemical substances provided by JAMP. AIS covers
chemical substances that are included in molds.
chemSHERPA：A format for communicating information of chemical substances which JAMP
provides. chemSHERPA-CI is for chemical substances contained in chemical
goods. chemSHERPA-AI is for those contained in articles.
#1：The latest law & regulation may not be included.

2. Regulating chemical substances included in suppliers’ products
2.1 Chemical substances regulated by Hitachi GroupThe Hitachi Group uses the "chemical substances regulated by the Hitachi Group guidelines" toclassify chemical substances contained in procured products into two separate categories, prohibited
substances and controlled substances.
Chemical substances regulated by the Hitachi Group guidelines
Classification
Regulated substances
These chemical substances are prohibited for inclusion in
Level 1 supplied products. Under regulations inside and outside
ProhibitedJapan, these chemical substances are basically prohibited
substances
for use in products (including packaging), but might beused in products supplied to the Hitachi Group.
For details, see Separate table 1 or Attached list 1.
Level 2 Controlled
substances

Under regulations inside and outside Japan, these aresubstances whose actual use must be known, and forwhich appropriate management is required, or controlled
substances whose recycling and proper disposal must be
considered. This also includes substance groups whose
inclusion in supplied products might be restrictedaccording to utility.
For details, see Separate table 2 or Attached list 2.

Main legal regulations
See Separate table 1 orAttached list 1

See Separate table 2 orAttached list 2

Note that the regulation factors (such 31as substance groups, control levels, and threshold values)
might vary depending on the operating division in the Hitachi Group due to circumstances such asindustry trends. Pay attention to the division's requested items, and check the items accordingly.
In addition, we might request an investigation of the chemical substances used in the production,
storage, and transport stages before delivery (even if the substances are not included in the delivered
product) with the objective of conserving supplies. Suppliers' cooperation is also requested.

2.2 Warranty of non-inclusion of chemical substances in procured products
In the Basic Agreement entered into when trading materials, the Hitachi Group requests our
suppliers to make certain considerations for the environment. Regarding chemical substances in theirproducts, suppliers are requested to conduct quality control by warranting the non-inclusion ofchemical substances in their products as necessary.
If non-inclusion of chemical substances in products is stated as a purchase specification requirementin the trade, documentations such as "Warranty of Non-Inclusion Concerning Banned Chemical
Substances in Products" (Warranty of Non-Inclusion) must be submitted to the Hitachi Group as adelivery specification requirement.
"Non-inclusion" indicates that the following is rationally proved regardless of whether inclusion ofthesubstance
isintentional:- Certain chemical substances are not included, or they are included but at an amount less than thedesignated threshold value.

2.3 Guidelines for regulating information about chemical substances included in
products (prohibition and control)
When collecting information about chemical substances contained in products, choose the best way
to do so from an economical and engineering standpoint.
Use of level 1 prohibited substances groups is basically prohibited according to regulations insideand outside Japan, so legally, their non-inclusion in products must be guaranteed.
For level 2 controlled substance groups, appropriate management of inclusion information isrequired regardless of whether the substances are included in the products. Suppliers are requested tofile reports in all cases; even statements such as "There is no information available that shows
inclusion of the chemical substances" are to be reported when appropriate.

2.4 Regarding changes in materials, manufacturing methods, and information
about included chemical substances
If any changes in materials, manufacturing methods, production location, major manufacturing
equipment, persons in charge of manufacturing, etc. are to be made for procured products, suppliers
are required to submit a notice about the details of the change and the scope of effect each time. In
addition, for information on inclusion of chemical substances, submission of a notice is mandatorywhen a new inclusion is discovered, or when previously-reported inclusions have changed.

depending on the product group to be surveyed.
- Some prohibited substances were used for various applications in the past as additive agents toachieve product performance characteristics. These might even be included incurrent products.
Various cases of erroneous use, mixing, and contamination of prohibited substances have beenreported, including those usually contained in raw materials in nature, remaining in products aftergeneration as by-products or used as subsidiary materials in the manufacturing process, being
mixed into products due to shared production lines or the use of alternative materials available ininventory.
Suppliers are requested to properly control prohibited materials in order to prevent their mixture
into products in excess of the threshold value by understanding their characteristics and tracking
their history, including those exempt from laws and regulations.

■ Definition of the denominator and the numerator for calculating the content
percentage of the mass of included chemical substances(1) Definition of the denominator
RoHS regulations: Homogeneous materials

Regulations other than RoHS : For each procured product or for each arbitrary class into which
procured products are divided[Definition of homogeneous material]
Homogeneous material refers to material that cannot be mechanically separated into other materials.
The following are homogeneous substances or homogeneous materials:
Composites
Judgment criteria
Chemical compounds, polymer
Homogeneous materials
alloys, metallic alloys, etc.
Materials that have undergone
Individual monolayers are considered homogeneous material.
painting, printing, plating(In the case of zinc plating chromate treatment, the zinc plating(chromate treatment) or otherlayer and the chromate treatment layer are considered separate
treatments
homogeneous materials. However, if it is difficult to obtain thevalues for individual monolayers by separating multilayers, theminimum separable unit is considered a homogeneous material
unit (JIS C 0950).)(2) Definition of a numerator“Chemical substances” refers to chemical elements or compounds.
Chemical substances
Definition of a numerator
Metals and metallic compounds etc.
Mass of metallic elements
Substances other than metals and metallic Mass of the chemical substancecompounds
The molecular mass relevant to the CAS number is to be filled in (actually larger than the massof metallic elements in the molecule) for the potential REACH SVHC.

■ Example registration of product composition information (Electrical part)
The Hitachi Group defines products, regions, and compositions (chemical substances) as shown in
the table and class chart below.
- Exempted substances not included in prohibited or controlled substances can all be categorized
as “other chemical substances”.
- “Chemical substances” refers to chemical elements or compounds.
- “Product parts” refers to the minimum unit that can be mechanically separated from othermaterials and is composed of homogeneous substances. (For details, see the A Gree’Net user's
manual.)14Ex) Aluminum electrolytic capacitor (weight: 3g)
