Green Purchase Standard

Established on December 1, 2001
Revised on July, 2023(Ver.23)
TAIYO YUDEN CO., LTD.

TAIYO－Version23

1. Introduction
TAIYO YUDEN Group promotes “to supply the Environmentally friendly products” as one of the top priority
issues on its environmental preservation activities. To realize this, it is essential for us to procure ecofriendly materials, parts and sub-materials (hereafter “Materials”) used in our manufacturing process. In
other words, each of our suppliers’ environmental efforts is taken into account as a key element in our
procurement activities.
As the definition of “Green Purchase”, that is, to preferentially procure the environmentally conscious
materials and parts from environmentally conscious suppliers, TAIYO YUDEN Group will give priority tosuch environmentally active suppliers, while considering the conventional focuses such as "Low Price","High Quality", and "Quick Delivery" as well.
This Standard sets the minimum rules, which TAIYO YUDEN suppliers are required to comply with.
Please note that this Standard shall be revised in accordance with the future changes in laws & regulation
as well as social trend accordingly.

2. Scope
This Standard shall apply to all the materials, parts, and other goods supplied to the TAIYO YUDEN Groupand its manufacturing/design subcontractors. List of companies within TAIYO YUDEN Group is attachedat the end of this document.
Object Materials: Examples(1) Parts:- Electronic parts, Electromechanical parts, Semiconductor devices, Printed circuit boards,
Functional units, Modules, Assembly parts such as Board A'ssy, etc.
(2) Materials:- Product composing materials (e.g. Compounded Materials for Ceramics, Resin, Solder,
Adhesives, Paste, Inks, Wire rods etc.)- Materials used in manufacturing process such as binder and solvent.
(3) In-process Materials:- Materials or tools used in production of product such as screen, cutting blade, PET film.
(4) Subsidiary Materials:- Packaging Materials
Trays, Reels, Sticks, Bags, Buffer Materials, Cardboards, Staples, Banding bands, Tapes, Labels,
Printing inks, Paints, etc.
- Instruction Manuals (attached with the products TAIYO YUDEN Group sells) etc.

3. Definition of Terms(1) Environment-Related Substance
The Substance with adverse effects on human health and environment, which is restricted by laws
and regulations, or which should be controlled by self-imposed regulation (TAIYO YUDEN specifies
the following (2) through (4) as Environment-Related Substances.)(2) Banned Substances
The substance whose inclusion in products is prohibited (Any substance under this category mustnot be used for all or certain application(s).) Substances which are prohibited or limited by applicablelaw and regulations, industrial guidelines, treaties, or limited by the customer. Intentional addition,
mixture/adhesion in process, and impurity content which may affect characteristics are banned. Whenthreshold is specified, impurity must be below threshold.
(3) Restricted SubstanceIn principle, the substance fallen into this category is banned to include in products. The use in limited
application is allowed if it is currently used and immediate prohibition is difficult, or there is noalternative substance.
Sifting to other materials shall be promptly proceeded by design change, change to alternative
substances, etc.
(4) Substance to be Controlled
The substance whose content in products should be controlled. (If any substances under this category
is contained in the products supplied to TAIYO YUDEN Group, the supplier must declare thesubstances and its content to us before starting the transaction of the products. TAIYO YUDEN Groupwill control these substance contents in our products, and if necessary due to legal requirement or
environmental trend, we will modify the status to avoid or reduce the usage.)1 / 12TAIYO－Version23(5) Contained
The situation in which a substance is added to, fills up, is blended with, or adheres to the parts ordevices employed in products, or the materials used for the parts or devices, whether the situation isintentionally created or not. (When a substance is unintentionally contained in, or added to a productin a processing process, this situation is also regarded as “Contained.”)(6) Intentional addition
Planned use of chemical substance as composition of materials or component in order to provide
specific feature, outline, or quality of product.
(7) Impurity
A substance contained in a natural material, which cannot be completely removed in a refining
process by technical means, and a substance generated in a synthesis process, which cannot becompletely removed by technical means. If they are used for the purpose of changing thecharacteristics of a material, they are treated as “Intentional addition”.
Where the threshold is specified concentration is set in this Standard, the environment-related
substance concentration must not exceed the threshold specified even though the substance isincluded as an impurity.
(8) Homogeneous materials
Materials or part which is wholly homogeneous composition. Or, materials or part which could not be
dissolved, or separated into different materials by mechanical measures (by screwing, cutting,smashing, crushing, grinding, etc.).
(9) Article
Article means “an object which during production is given a special shape, surface or design which
determines its function to a greater degree than does its chemical composition.” (EU REACH
Regulation Article 3, Section 3).
e.g. PC, TV, Cell Phone, Electronic Parts, Capacitor, Filter, Lamp etc.
(10) Substance/Mixture
Substance means “a chemical element and its compounds in the natural state or obtained by any
manufacturing process, including any additive necessary to preserve its stability and any impurity
deriving from the process used, but excluding any solvent which may be separated without affecting
the stability of the substance or changing its composition.” (EU REACH Regulation Article 3, Section
1)e.g. Methane, Hydrocarbon, Sulfuric Acid, Ethanol, Calcium Carbonate, Silicon Dioxide, Metals (forexample, Copper, Aluminum)Mixture means “ a mixture or solution composed of two or more substances. ” (EU REACH
Regulation Article 3, Section 2)
e.g. Paints, Lubricant Agent, Adhesive Agent, Cleaning Agent, Alloy (for example, Steel, Brass)(11) SVHC (Substance of Very High Concern)
Substance of Very High Concern (SVHC) which has possibility to be listed in the Annex XIV on
REACH.
These substances are highly toxic to Carcinogenicity, Persistent and Bioaccumulation.

4. Basic Concept of Green Purchase
Green Purchase Standard of TAIYO YUDEN Group consists of 2 items: (1) Supplier's Criteria forEnvironment-related Substance Management System, (2) Criteria for Environmental Consideration inMaterials. Before commencement of new transaction, TAIYO YUDEN Group effort for Environmental
Preservation shall be agreed by concluding "Environmental Agreement: Form 6" with supplier.
4.1 Criteria for Environment-related Substance Management System(1) TAIYO YUDEN Group shall make preferential transaction with suppliers who have Environmentrelated Substance Management System to prevent inclusion of Banned Substances.
In define,- There is system to ensure no inclusion of harmful chemicals in procured materials of suppler.
- There is control in process to prevent generation or mixture of harmful chemicals.
- In materials to be delivered to TAIYO YUDEN Group, there is system to ensure no inclusion ofharmful chemicals.
- In case of change in contained substance, there is system to obtain prior approval from TAIYOYUDEN Group.
- In case of abnormality in contained substance, there is system to make prompt report to TAIYOYUDEN Group.
2 / 12TAIYO－Version23(2) Evaluation shall be made at the time of initiating transaction, and form then onward, on a periodic
basis (every other year). To be more precise, we will check the Form-5: Green Purchase Evaluation
Sheet filled out by suppliers. Moreover, we will visit the supplier’s factory(factories) to conduct
audit(s) if necessary; in case that the supplier is requested for cooperation on such audit(s) by the
TAIYO YUDEN’s division in charge, the company shall respond to the request.
(3) Regarding Green Purchase Evaluation Sheet, according to evaluation score, Environmental Rating
as shown in Table 1 shall be marked which shall be reflected to our materials purchasing.
