MANUFACTURING
RESTRICTED SUBSTANCES LIST
VERSION 2.0 - MARCH 2016

MRSL VERSION 2.0 - MARCH 2016

INTRODUCTION
ScopeThis Manufacturing Restricted Substance List (MRSL) applies
to all G-Star Raw C.V. suppliers. The document addresses
hazardous substances potentially used and discharged into
the environment during manufacturing and related processes,
not just those which could be present in finished products.
G-Star Raw C.V, anticipates that suppliers will work closely with
their chemicals suppliers to ensure substances mentioned inthis MRSL are not present in any of the chemical commercial
products that are purchased from chemical suppliers.
This MRSL is an important part of G-Star's Corporate
Responsibility program and must be shared with all suppliers,sub-contractors and others involved in the production of G-Star
products.
The following production processes are targeted by thisdocument: Textile and synthetic leather, so as leather processing.
Background
G-Star Raw C.V. is a member of the Zero Discharge of Hazardous
Chemicals Foundation (ZDHC) and committed to defined anddevelop a Manufacturing Restricted Substance List (MRSL) for
the apparel and footwear industry. In doing so, brands recognized
the value of addressing hazardous substances potentially usedand discharged into the environment during manufacturing andrelated processes deep within our supply chain - not just those
substances that could be present in finished products. In June
2014, the ZDHC brands achieved a significant milestone andpublished the first version of the ZDHC MRSL.
Purpose of the list
G-Star cares about consumers and the environment. Our
suppliers are critical partners in our commitments in the areaof consumer safety and environmental protection. The MRSL
contains a list of chemical substances by CAS# that are subject
to a usage ban.

The MRSL applies to chemicals used in the manufacturing ofmaterials, components and finished products, which include
solvents, cleaners, adhesives, paints, inks, detergents, dyes,
colorants, auxiliaries and finishing agents used during raw
material production, wet processing, maintenance, waste water
treatment, sanitation and pest control. There should be no
intentional use of the MRSL listed substances in facilities.
IMPORTANT
Threshold limit values on restricted substances in chemical
formulations are in some cases substantially higher than limits
on restricted substances in finished products. This is because
restricted substances in finished products are almost always
found in smaller concentrations than in the chemical formulations
used to produce them. Chemical formulations are highly
concentrated before being diluted upon application to textiles andother materials.
Note: The MRSL does not replace applicable national
environmental or workplace safety restrictions. Worker exposure
to the listed and other hazardous substances must not exceed
occupational exposure limits and chemical formulations mustcomply with all applicable legal restriction, including any
subsequent restrictions that establish stricter limits. The MRSL
does not replace legal restrictions on hazardous substances infinished products (RSL requirements).
G-Star Raw C.V. advises you to communicate the MRSL
requirements to raw material supplier, including sub-contractors
and factories assembling or manufacturing garments andfootwear. To support our goal of using MRSL compliant
formulations, G-Star Raw C.V. also expects that material suppliers
and factories will communicate with the chemical suppliers
to ensure that listed substances are not present in chemical
formulation above established limits.

Definitions
Chemical Substancemeans a chemical element and its compounds in the natural stateor obtained by any manufacturing process, including any additivenecessary to preserve its stability and any impurity derivingfrom the process used, but excluding any solvent which may
be separated without affecting the stability of the substance orchanging its composition.
Commercial Chemical Productis a proprietary blend of several chemical substances or areaction product used to create a 'trade name' or 'functional'
product that is available for purchase from a chemical supplier.
Note this document will not list commercial chemical products.
CAS - Chemical Abstract Service index number
It is a unique numeric identifier, designates only one substance,
has no chemical significance, is a link to a wealth of information
about a specific chemical substance.
It includes up to 9 digits which are separated into 3 groups byhyphens. The first part of the number, starting from the left, has
up to 6 digits; the second part has 2 digits and the final partconsists of a single check digit.

MRSL VERSION 2.0 - MARCH 2016

INTRODUCTION
Usage Ban
Chemical Products used for the manufacturing of articles (e.g.
colorants) must not intentionally contain these substances orsubstances groups.
MRSL Creation Process
The MRSL includes relevant substances from the original
11 priority chemical groups along with additional substances
discussed with qualified experts from the Zero Discharge ofHazardous Chemicals Technical Advisory Committee(ZDHC TAC). Several of the listed substances are regulationin finished products and have been successfully restricted foryears. Though already restricted by ZDHC brands, their inclusionon the list keep it consistent with existing industry standards.
Where possible, the content of the MRSL was peer-reviewed
by independent third-party technical experts and industry
associations related to the production of our key raw materials.
Collaboration with leading technical experts allows to develop a
MRSL that pragmatically represents progress and supports ourlong-term goal of zero discharge.
MRSL Instructions

Organotins are a class of chemicals
combining tin and organics such as
butyl and phenyl groups. Organotins are
predominantly found in the environment
as antifoulants in marine paints, butthey can also be used as biocides (e.g.,
antibacterials), catalysts in plastic andglue productions, and heat stabilizers inplastics/rubber. In textiles and apparel,organotins may be associated withtextiles plastics/rubber, inks, paints,
metallic glitter, and heat transfer material,
but also in polyurethane coatings andpolyurethane membranes.

Polycyclic Aromatic Hydrocarbons(PAHs) are natural components of crude
oil and they are a common residue fromoil refining. PAHs have a characteristic
smell similar to the smell of car tires orasphalt. Oil residues containing PAHs
are added in rubber and plastics as asoftener or extender. Therefore, PAHs
are risky in rubber, plastics, lacquersand coatings. PAHs are often found in
the outsoles of footwear and in printing
pastes of screen prints. PAHs can bepresent as impurities in Carbon Black.
Clean mineral oils should be used in therubber to avoid PAHs.

Disperse dyes are a class of waterinsoluble dyes that penetrate the fiber
system of synthetic or manufacted fibers
and are held in place by phyiscal forces
without performing chemical bonds.
Disperse Dyes are used in synthetic
fiber (e.g. polyester, acetate, polyamide).
Restricted disperse dyes are suspectedof causing allergic reactions and should
no longer be used for dyeing of textiles.

MRSL TEXTILES AND SYNTHETIC LEATHER PROCESSING

Disperse dyes are a class of waterinsoluble dyes that penetrate the fiber
system of synthetic or manufacted fibers
and are held in place by phyiscal forces
without performing chemical bonds.
Disperse Dyes are used in synthetic
fiber (e.g. polyester, acetate, polyamide).
Restricted disperse dyes are suspectedof causing allergic reactions and should
no longer be used for dyeing of textiles.

300ppmPolycyclic Aromatic Hydrocarbons(PAHs) are natural components of crude
oil and they are a common residue fromoil refining. PAHs have a characteristic
smell similar to the smell of car tires orasphalt. Oil residues containing PAHs
are added in rubber and plastics as asoftener or extender. Therefore, PAHs
are risky in rubber, plastics, lacquersand coatings. PAHs are often found in
the outsoles of footwear and in printing
pastes of screen prints. PAHs can bepresent as impurities in Carbon Black.
Clean mineral oils should be used in therubber to avoid PAHs.

In the leather chemical industry,
naphthalene is used as raw material for
manufacture of synthetic tanning agents(syntans) and for manufacture of active
substances in dispersing agents usedduring leather processing.
