Organotin is a hazardous substance that is subject to mandatory restrictions on its use in exports to the European Union, and is often included in the environmental compliance requirements of buyers. Common control requirements for organotin include:

REACH SVHC: reaction materials and derivatives of tributyltin oxide (TBTO), dibutyltin dichloride (DBTC), di (2-ethylhexyl mercaptoacetate) tin (DOTE), di (acetylpyruvate) dibutyltin (DBTP), di (2-ethylhexyl mercaptoacetate) tin (DOTE), and tri (2-ethylhexyl mercaptoacetate) octyltin (MOTE), where C12 is the main carbon atom of the fatty acyloxy group.

When the concentration of SVHC in "goods" products exceeds 0.1%, information transmission and SCIP notification obligations need to be fulfilled, and if the total amount entering the EU is greater than 1 ton/year, notification obligations need to be fulfilled to ECHA.

REACH Restricted Article:

Organic tin: cannot be sold on the market when used as a component of a substance or mixture in bio insecticides for free combination coatings; Not allowed to be listed or used as a component of a substance or mixture for use as a biological insecticide: for ships, any facilities used in aquaculture farms; Any appliance or equipment partially or completely submerged in water shall not be used as a component of a substance or mixture for the treatment of industrial water.

Trisubstituted organotin compounds (such as TBT, TPT, etc.): Starting from July 1, 2010, no more than 0.1% of trisubstituted organotin compounds (calculated by tin content) shall be used in goods.

Dibutyltin compounds (DBT): Starting from July 1, 2012, no more than 0.1% of DBT compounds (based on tin content) shall be used in items.

Dioctyltin compounds (DOT): Starting from July 1, 2012, daily necessities such as textiles, gloves, shoes, diapers, etc. shall not use more than 0.1% of DOT compounds (calculated by tin content).

EN71-3: Methyltin, Dimethyltin, Butyltin, Dibutyltin, Tributyltin, Tetrabutyltin, Octyltin, Dioctyltin, Dipropyltin, Diphenyltin, Triphenyltin (the migration limit of organic tin varies depending on the toy material):

Category I: 0.9mg/kg;

Category II: 0.2mg/kg;

Category III: 12mg/kg.

GB/T 39498-2020 "Guidelines for the Use and Control of Key Chemical Substances in Consumer Goods":

Dioctyltin compound: suitable for textile products, gloves, footwear or parts of footwear that come into direct contact with the skin, wall and floor coverings, children's care products, women's hygiene products, diapers, with a tin content of ≤ 0.1%.

Dimethyltin, diphenyltin, dipropyltin, butyltin, octyltin, methyltin, phenyltin trichloride, tetrabutyltin, tetraethyltin, tricycloethyltin chloride, trimethyltin chloride, trioctyltin chloride, and trin-propyltin chloride: The migration amount of organic tin compounds in dry, fragile, powdered, or flexible toy materials is required to be ≤ 0.9mg/kg; Require the migration amount of individual organic tin compounds in liquid or viscous toy materials to be ≤ 0.2mg/kg; The migration amount of individual organic tin compounds in toy materials that can be scraped off is required to be ≤ 12mg/kg.
