Pre-Registration	Companies must pre-register NMDC before submitting a full registration dossier.
Registration Dossier	A detailed technical file must be submitted, including information on physicochemical properties, toxicity, ecotoxicity, and risk management measures.
Substance Evaluation	EU authorities may request additional data or testing to assess the risks associated with NMDC.
Authorization	NMDC is not currently subject to authorization, but it may be restricted under certain conditions.
Restriction	NMDC is not currently restricted, but companies must comply with any future restrictions imposed by the EU.

2.4. Toxic Substances Control Act (TSCA)

In the United States, the TSCA regulates the manufacture, import, processing, and distribution of chemical substances, including NMDC. Under TSCA, NMDC is listed on the TSCA Inventory, and companies must comply with reporting, record-keeping, and testing requirements. The following table outlines the key TSCA requirements for NMDC:

Requirement	Description
Pre-Manufacture Notification (PMN)	If NMDC is being manufactured or imported for the first time, a PMN must be submitted to the EPA.
Significant New Use Rule (SNUR)	NMDC is not currently subject to a SNUR, but companies must notify the EPA if they intend to use NMDC for a significant new use.
Import Certification	Importers of NMDC must certify that the substance complies with TSCA regulations.
Reporting and Record-Keeping	Companies must maintain records of NMDC production, import, and use, and report any significant adverse effects to the EPA.

3. Domestic Regulatory Framework

In addition to international regulations, countries have their own national laws and regulations governing the trade of NMDC. Below are some examples of domestic regulatory frameworks in major markets:

3.1. China

China has implemented strict regulations to control the production, import, and use of chemicals, including NMDC. The primary legislation governing chemical trade in China is the "Regulations on the Administration of Chemicals" (RAC).
