TSCA: Toxic Substances Control Act
Definition
The Toxic Substances Control Act (TSCA) of 1976 authorized the U.S. Environmental Protection Agency (EPA) to track the 86,000+ industrial chemicals currently produced or imported into the United States. The EPA repeatedly screens these chemicals and can require reporting or testing of those that may pose an environmental or human-health hazard. EPA could (in theory; see below) ban the manufacture and import of those chemicals that pose an unreasonable risk.
A number of changes to the Act took effect on June 22, 2016; see the Frank R. Lautenberg Chemical Safety for the 21st Century Act information below.
TSCA applies to organizations that involve the manufacture, processing, distribution in commerce, use, and/or disposal of a new or existing chemical substance or mixture that may present an unreasonable risk of injury to health or the environment. The reporting threshold was raised in 2002 from 10,000 lbs (4,500 kg) to 25,000 lb (11,340 kg) per year. Most businesses that meet the 40 CFR 704.3 definition for small manufacturer or importer are exempt from reporting requirements. A business meets that criterion when total annual sales are less than $40 million and the manufacturing or import volume is less than 100,000 pounds (45,360 kg) at all sites.
By definition, TSCA-regulated chemical substances and mixture do not include "...any source material, special nuclear material, or byproduct material (as such terms are defined in the Atomic Energy Act of 1954 and regulations issued under such Act)..." [TSCA, Section 3(2)(B)(iv)]. Although TSCA excludes nuclear material, the TSCA-regulated portion of a mixed nuclear and regulated waste must comply with TSCA requirements. Materials that are not chemical substances or mixtures are not subject to the requirements of TSCA.
Any substance that is not on the Inventory is classified as a new chemical. If a substance is "new", it can be manufactured for a commercial purpose only if it is subject to an exemption from PMN (Premanufacture Notice) reporting or a TSCA reporting exclusion. For substances which are "existing", the Inventory can be used to determine if there are restrictions on manufacture or use. See Further Reading below for more information.
Under the Inventory Update Rule (IUR) the TSCA inventory is updated every 5 years. Prior to 2006, the update period was 4 years. Some new changes included in the 2002 update were:
Increased the reporting threshold from 10,000 to 25,000 pounds.
Require companies to include data on inorganic chemicals.
Include the number of workers likely exposed a chemical in its manufacture.
List the uses of each substance.
Require businesses to present "up-front substantiation" to claim a chemical identity as proprietary information that must be held in confidence by the EPA.
Certain natural gas streams are exempted from all reporting. Other groups of chemicals, including most petroleum streams and certain chemicals that are of low current interest, are now partially exempt from reporting and are not required to report processing and use information.
The idea of the higher reporting limit is to reduce the additional burden associated with covering more chemicals. As one might expect, both chemical manufacturers and community/environmental groups like some of these changes more than others.
Frank R. Lautenberg Chemical Safety for the 21st Century Act
The EPA's ability to ban chemicals under the original implementation of TSCA was a dismal failure. Only five chemicals were ever explicitly banned. In 1989, after ten years of study and spending ten million dollars, EPA issued a Final Rule which banned asbestos, a known and potent human carcinogen for which there are multiple and far safer alternatives and removal of which is so dangerous that it is governed by an array of safety regulations. However, the Final Rule was vacated in 1991 in an absurd court ruling that TSCA required the EPA to prove it had analyzed every conceivable way of restricting asbestos and had chosen the "least burdensome alternative" to industry. EPA basically gave up on efforts to ban chemicals after that point, and to this very day, asbestos may still be legally included in a host of materials, which not only expose the workers who manufacture and install it, but also any unsuspecting person who unwittingly disturbs the material and releases asbestos fibers into the air.
In September of 2009, the Obama administration unveiled broad proposals to reform TSCA and give the EPA the ability to ban or restrict unsafe chemicals. Supporting legislation was announced by US Senators Frank Lautenberg (Democrat, NJ) and James Jeffords (Independent-VT) in 2010, but after a number of hearings and stakeholder sessions, the bill died amidst industry opposition. After considerable effort, on June 22, 2016, the Frank R. Lautenberg Chemical Safety for the 21st Century Act was signed which made many needed improvements although it fell far short of the original goals. Under the revisions, the following changes were made.
A mandatory requirement for EPA to evaluate existing chemicals with clear and enforceable deadlines
A new risk-based safety standard for new chemicals
New requirements for confidentiality claims
Consistent funding for the program through user fees
Federal-state partnership for when state and federal laws conflict
Amends the Mercury Export Ban Act (MEBA) and requires that EPA create an inventory of supply, use, and trade of mercury and mercury compounds.

Critics point out the Act is so watered down that the EPA wouldn't begin testing chemicals for three years, and even then the initial list included only 3 solvents, 20 chemicals, and asbestos, all of which were already on EPA's agenda, leaving 30,000+ high-production chemicals untested. Further, within days of the signing of the act, it became clear that politicians and other parties would begin demanding that the EPA give their personal concerns priority instead of letting the EPA do its job - determining which chemicals pose the greatest risk based on exposure levels, production volume, individual hazards, and known human health effects.
The Trump administration's implementation of the testing provisions was met with great criticism for concealing health studies and violating transparency provisions. Critics have pointed to ten failures in the EPA's April 2019 asbestos Significant New Use Rule (SNUR), a rule that could conceivably allow asbestos back on the US market for certain applications. This comes on top of the administration's attempt to bar the use of some of the best available health information on certain chemicals under the misleadingly named "Strengthening Transparency in Regulatory Science" rule that has been widely condemned by the scientific community.

SDS Relevance
Much of the information contained in the TSCA database overlaps, parallels or supplements the information found on Safety Data Sheets. Some SDS's may refer to particular TSCA items, and TSCA information can be useful when constructing a new SDS sheet.
Some SDS's may contain code letters that are used in the TSCA Inventory to identify substances that are the subject of an EPA rule or order
promulgated under TSCA, or to indicate the a full or partial exemption from TSCA reporting requirements. These codes are not required to be on an SDS. In our opinion, these codes are completely useless to the end user - why give a cryptic code instead of simply writing out what the code stands for?
Note: Some of the letters/symbols used in this table are also used as CHIP, HMIS, and/or DoD HMIRS/HCC codes, all of which have completely different meanings and applications! See why we dislike code systems?
