Article 2  
The term “registrant” as used herein means a natural person, a juristic person, an 
unincorporated body having a representative  or manager, an administrative authority, or a 
person, who may be the subject of rights and obligations under other laws, that is subject to  2 chemical substances registration pursuant to Article 7 -1 of the Act.

affairs covered in the Regulation s. The representative should be a natural person possessing the 
nationality of the Republic of China, or a juristic person, an institute or an organization that is 
constituted or regi stered by law.  
When applying for chemical substance registration according to the Regulations , a 
registrant shall attach a copy of a National Identification Card, a copy of company registration, 
business registration, factory registration, or other documents verifying the registrant’s 
establishment. A representative shall provide a notarized or certified appointment letter.  
 
Article 3

its stability and any unintended constituent s deriving from the processes used, but 
excluding any s olvent which may be separated without affecting the stability of the 
substance or changing its composition.  
II. “Substance which Occur s in Nature ” refers to a substance that is: unprocessed; processed 
only by manual, gravitational, or mechanical means; by diss olution in water; by water 
extraction; by vapor distillation; by flotation; by heating solely to remove water; by 
extraction from air by any means, without chemical change in the substance; or, large 
molecules from organisms, or polymers occurring in natur e and not chemically processed.  
III. “Mixture ” refers to a mixture or a solution composed of two or more substances in which 
they do not react.  
IV. “Article ” refers to a manufactured item formed to a specific shape or design during 
manufacture.  
V. “Polymer ” refers to a chemical substance that fits the following criteria:  
A. A macro -molecular chemical substance consisting of molecules characterized by the 
sequence of one or more types of monomer units.

C. Differences in the molecular weight are primarily attributable to dif ferences in the 
number of monomer units. 
VI. “Polymers that the 2% Rule is Applicable ” refers to a polymer when its monomers or 
reactants may not be regarded as part of the polymer when the weight percentage of the 
monomers or reactants is less than two percen t; if the naming of the polymer is a 
monomer -based representation, it may or may not include monomers and other reactants 
used at two  percent weight or less. A monomer -based representation means  the naming of  3 polymers is  based on constituent monomers.

XI. “Impurity ” refers to an unintended constituent present in a  substance as produced. It 
originates from the starting materials or is the result of secondary or incomplete reactions 
during the production process. While it is present along with the final substance , it was 
not intentionally added, nor does it enhance t he commercial value of that substance. The 
concentration of an individual impurity is no more than 10% (w/w). All impurities 
presented are no more than 20% (w/w).

registration.  
For a joint registration that is agreed upon by co -registrants, but for which no agreement 
has been reached on the cost sharing of the registration information, the co- registrants may 
submit an equal -cost-sharing request application to the central competent authority. The 
registered chemical substance information can be used after the shared cost has been paid

extensions before the original approval registration expires, those who fail to file the extension 
application pursuant to the  preceding  Paragraph 1 shall stop manufacturing or importing the 
new chemical substance after the valid period of the original approved registration expires. If a 
registrant does not apply for an extension before the valid period expires, the original approved 
registration is revoked exactly on the following day of the expiration day specified with the 
original approved registration. A new application of registration shall be made in order to 
continue manufacturing or importing suc h chemical substance.

items marked with “V” should be submitted. 
5. The central competent authority may designate registration information to be submitted based 
on information collected from Phase 1 registration of existing chemical substances and 
international information on chemical substances. Other requirements to be met shall refer to 
the registration tools released by t he central competent authority.  
6. All of the co -registrants among joint registration pursuant to Article 17 of the Regulation s shall 
submit information according to the registration tools and forms released by t he central

Note:  
a. For existing chemical substances manufactured or imported, pursuant to Article 16, minimum 
information on physical and chemical properties, toxicology, and ecotoxicology of the existing 
chemical substances  shall be submitted as follows:  
i. Level I testing data sh all be submitted for substances in annual manufactured or imported 
volume of 1 ton or more, but less than 10 tons;  
ii. Level II testing data shall be submitted for substances in annual manufactured or imported 
volume of 10 tons or more, but less than 100 tons ; 
iii. Level III testing data shall be submitted for substances in annual manufactured or imported 
volume of 100 tons or more, but less than 1,000 tons;  
iv. Level IV testing data shall be submitted for substances in annual manufactured or imported 
volume of 1,000 t ons or more. 
b. For existing chemical substances manufactured or imported that meet the definition of 
carcinogenic, mutagenic or toxic to reproduction (CMR) Category 1, pursuant to Article 16, 
minimum information on physical and chemical pro perties, toxicolog ical, and eco toxicological 
of the existing chemical substances shall be submitted as follows:  
i. Level II testing data along with Section 8 --Hazard assessment and Section 9 --Exposure 
assessment shall be submitted for substances in annual manufactured or imported volume of 
1 ton or more, but less than 10 tons;
