EPA TRI Category Code: N270

Hexabromocyclododecane (EPA TRI Category Code N270) is a chemical tracked by the EPA Toxics Release Inventory (TRI) program under Section 313 of the Emergency Planning and Community Right-to-Know Act. The TRI requires industrial facilities above specified threshold quantities to disclose annual manufacturing, processing, and otherwise-used volumes, along with quantities released to air, water, land, and off-site transfers.

Across the United States, 5 facilities have filed TRI Form R disclosures for Hexabromocyclododecane, with a cumulative reported release volume of 166.8K lbs. The chemical is not flagged as a carcinogen in the TRI classification set. It is also listed as a persistent, bioaccumulative, and toxic (PBT) substance, a category subject to lower reporting thresholds and elevated regulatory concern. The largest individual disclosure in the current dataset comes from EQ DETROIT INC in MI at 127.8K lbs.

TRI volumes are self-reported estimates, not measured stack emissions, and each pound counts equally regardless of chemical toxicity, so total pounds should not be equated with total risk. Inclusion of a chemical or facility in the TRI does not itself establish a health hazard; it documents the public right-to-know record. Consult EPA's IRIS (Integrated Risk Information System) and the Agency for Toxic Substances and Disease Registry for health-effect summaries.

Frequently Asked Questions

What is Hexabromocyclododecane? ▼
Hexabromocyclododecane (EPA TRI Category Code: N270) is a chemical tracked by the EPA Toxic Release Inventory (TRI) program. It is classified as a persistent bioaccumulative toxicant (PBT). 5 facilities in the United States report releasing this chemical to the EPA.
How much Hexabromocyclododecane is released in the U.S.? ▼
U.S. facilities have reported a total of 166.8K lbs of Hexabromocyclododecane releases to the EPA Toxic Release Inventory across 5 facilities. Release quantities are self-reported estimates. This includes releases to air, water, land, and off-site transfers.
Is Hexabromocyclododecane harmful to health? ▼
Hexabromocyclododecane is not classified as a carcinogen in the EPA TRI database. It is classified as a persistent bioaccumulative toxicant (PBT), meaning it persists in the environment and accumulates in food chains. Health effects depend on exposure levels, duration, and route. For specific health questions, consult a toxicologist or your local health agency.
Which facilities release the most Hexabromocyclododecane? ▼
The largest reported releasers of Hexabromocyclododecane include facilities across multiple states. Release data is self-reported annually to the EPA under the TRI program. View the full list of 5 facilities on this page.
Why is Hexabromocyclododecane listed under code N270 instead of a CAS number? ▼
N270 is an EPA TRI Category Code, not a CAS Registry Number. EPA assigns category codes (N-prefix and K-prefix) to chemical groups that share reporting requirements, for example, "Hexabromocyclododecane" covers many distinct compounds aggregated for TRI reporting. Individual constituents may have their own CAS Registry Numbers (e.g., elemental Lead is CAS 7439-92-1), but the group is reported under the single TRI Category Code.

Health Information

Persistent Bioaccumulative Toxicant (PBT): This chemical is classified as a PBT by the EPA. PBT chemicals are toxic, persist in the environment, and bioaccumulate in food chains. Because of these properties, even relatively small releases can pose a significant threat to human health and the environment over time.

Data comes from the EPA Toxic Release Inventory (TRI) program. Release quantities are self-reported by facilities and may represent estimates. The total shown aggregates reports across all facilities and reporting years.

PlainEnviro presents this data without advocacy framing. The presence of a chemical in the TRI database does not by itself indicate a health risk at current exposure levels. For health-related questions about specific chemical exposures, consult your local health agency or a toxicologist.
