[Polymer] Registration of Polymer under K-REACH

A new polymer which does not satisfy polymer exemption conditions under K-REACH shall be registered like new substance. However, required test data for a polymer are less than those for a substance. Please refer to the following table for data requirements in accordance with tonnage bands.

Volume of manufacture and import	Data requirements
① 0.1 ~ 1ton/yr	- Physicochemical properties (state of substance, water solubility, melting/freezing point, boiling point, vapor pressure) - GPC data - Stability in acidic and alkaline conditions
② 1 ~ 10ton/yr
③ 10 ~ 100ton/yr	- Data requirements of ①, ② - Acute oral toxicity (Acute inhalation toxicity shall be needed in case the main exposure pathway is considered as inhalation) - Ames test - Acute fish toxicity - Ready biodegradability
④ 100 ~ 1000ton/yr	- Data requirements of ③ - Physicochemical properties (octanol/water partition coefficient, density, granulometry) - Skin irritation/corrosiveness - Skin sensitization - Acute daphnia toxicity
⑤ Over 1000ton/yr	- Data requirements of ④ - Physicochemical properties (flammability, explosive properties, oxidizing properties) - Acute dermal toxicity or acute inhalation toxicity - Eye irritation/corrosiveness - In vitro chromosome aberration using mammalian culture cell - Genetic toxicity - 28days repeated dose toxicity - Reproductive and developmental toxicity: screening * can be substituted with test protocol - Freshwater algae growth inhibition - pH hydrolysis

* Polymer compounds with 1,000≤Mn<10,000 whose monomers, which are new chemicals, hazardous chemicals and chemicals with hazard and risk or announced by MoE, exceed 2%weight shall be registered, but if content of residual monomer is less than 0.1%, only physicochemical test data are required.
