TSCA是英文Toxic Substances Control Act 的缩写，中文意思是：有毒物质控制法案。
TSCA最早是由美国国会于1976颁布，1997正式生效，具体实施是由美国环境保护局负责，这个法案是综合考虑美国境内流通的化学物质对其环境、经济和社会的影响，预防化学物质对人体健康和环境的“不合理风险”。2021年TSCA又明确规定了五种化学物质在各类产品中的具体含量，目前出口到美国的产品属于TSCA监管的，TSCA合格是基本要求了，成为了中美贸易的基础条件。
Under Section 13 of the Toxic Substances Control Act (TSCA), chemical substances, mixtures, or articles not in compliance with TSCA, or whose importation is not in compliance with TSCA, must be denied entry into the customs territory of the United States. There are three different situations concerning TSCA certification statement.
A positive certification statement is required for chemical substances subject to TSCA. The importer must certify by a statement on the entry document or invoice that any shipment of a chemical substance subject to TSCA, complies with TSCA, and that it is not offered for entry in violation of TSCA or rules or orders under TSCA.
建议向美国出口商品的公司与美国进口商合作，在必要时提供正面或负面认证声明。遵守TSCA始终是向美国进行化学品贸易的先决条件。请检查您的货物是否符合TSCA，如果是这样的话，一份积极的证明声明才是真正有助于你进入美国市场的护照。
