美国TSCA是什么、TSCA认证哪里可以办理?

EPA’s compilation of the public TSCA Inventory information is updated twice a year to include new and corrected TSCA Inventory chemical listings, and it contains none of the chemical identities claimed as confidential. Thus it is not as complete nor current as the information contained in EPA's TSCA Master Inventory File, which includes the chemical identities claimed as confidential and is updated continuously as new and corrected information is received by EPA. Consequently, for the purposes of TSCA compliance, the TSCA Master Inventory File maintained by EPA's Office of Pollution Prevention and Toxics is the only complete and accurate source that can provide authoritative and conclusive information about which chemical substances are currently included in the TSCA Inventory.

美国环保局对《有毒有害物质清单》公开信息的汇编每年更新两次，以包括新的和更正的《有毒有害物清单》化学品清单，其中不包含任何声称保密的化学品身份。因此，它不像美国环保局TSCA主清单文件中包含的信息那样完整和最新，该文件包括被声称为机密的化学品身份，并随着美国环保局收到新的和更正的信息而不断更新。因此，为了符合TSCA，由美国环保局污染预防和毒物办公室维护的TSCA主清单文件是唯一完整和准确的来源，可以提供关于哪些化学物质目前包含在TSCA清单中的权威和结论性信息。

一旦环保局收到完整的NOC，报告的物质就被视为清单上的物质，并成为“现有化学品”。环保局每年收到大约400个NOC，因此TSCA清单几乎每天都在变化。
