Completion of Registration of Chemical Substances
The Japan Paper Association (JPA) has been improving management system ofchemicals used in pulping and papermaking process, in order to ensure higher
level of food safety, in response to increasing public awareness of harmful chemical
substances and international movement toward control of the substances. As partof such efforts, last year, JPA started the registration of existing chemicalsubstances used in producing paper and paperboard for food contact containers
and packages to “JPA-ChemiNet” which is an open database among registeredmembers. The registration work was completed in March, 2011.

Registration of Existing Chemical Substances to JPA-ChemiNet
Procedures for registering existing chemical substances to JPA-ChemiNet are thefollowing:1) If chemical suppliers are members of the ChemiNet, paper manufacturers
shall notify them of the chemicals used for producing paper and paperboard forfood contacts, and they shall register the composition of the chemicals for theChemiNet.
2) If the chemical suppliers are nonmembers of the ChemiNet, they shall notify
paper manufacturers of the composition of the chemicals, and manufacturers
shall register them for the ChemiNet.
3) In case that the suppliers refuse to disclose the composition of the Chemicals,
the chemicals cannot be registered for the ChemiNet. If manufacturers would
like to continue to use the chemicals that cannot be registered, they have toensure the safety of the products through risk assessment.

Membership of JPA ChemiNet
As of May 2011, the number of registered members of the ChemiNet is 143, ofwhich, 34 are paper manufacturers and 109 chemical suppliers. For chemicalsuppliers, in addition to 109 registered members, over 10 nonmember suppliers
register their products to the ChemiNet through paper manufacturers. In thiscontext, JPA recognizes that registration of all of chemicals which are or were usedin producing paper and paperboard for food contact containers and packages has
been completed. However, all the registered existing chemicals are those which areused in paper manufacturing mills, not including the chemicals used in converting
plants and printing factories. Therefore, it is necessary for related industries toconsider appropriate measures when needed.

Classification of Registered Chemical Substances
JPA made a tentative classification of the registered chemical substances - over
1,900 substances into six categories based on certain standards (like positive list
systems in western countries). JPA will conduct risk assessment of each substancebased on hazardousness and exposure to make a definitive classification.
Assessment results and the definitive classification will be disclosed to the public.
Description of the six categories is as follows:
1. Substances Group 1-A(Substances that are not listed in both JPA’s Negative List (NL) and candidate
substances for the Negative List (CNL), and listed in the positive list (PL) inthe western countries)
2. Substances Group 1-B(Substances t that are not listed in both JPA’s NL and CNL, but are not listedin PL in the western countries)
3. Substances Group 2-A(Substances that are listed in JPA’s CNL, while being listed in PL in thewestern countries)
4. Substances Group 2-B(Substances that are listed in JPA’s CNL and are not listed in PL in thewestern countries)
5. Substances for which CAS registry number are unidentified
6. Substances contained in dyestuff
Note: More information on JPA’s NL and CNL is described in the Appendix.

Registration of New Chemical Substances
JPA will start acceptance of new chemical substances registration in May.
Registration applicants will be required to submit information on the substanceincluding hazardousness (e.g. physicochemical character), regulations andexposure (e.g. additive amount in paper making and residual volume in paper
produced). Submitted information will be shared among the ChemiNet members,and members collectively will conduct a risk assessment to determine whether thesubstance can be registered to the ChemiNet.

6.

Future Works
JPA will promote risk assessment of registered existing chemical substances withclosely examining their hazardousness and exposure. For examining exposure,
JPA will divide the substances into the following three categories to estimate, or insome cases measure residual volume of each substance in base paper produced.
1. Substances used in papermaking process for quality control and remain in
paper produced
2. Substances used for controlling papermaking process and are unlikely toremain in paper produced.
3. Substances used in wood pulp or recovered paper pulp production process andare unlikely to remain in paper produced.
