This is a brief user's guide to the TRI Search. Select a variety of different search options and output options detailed below.

Select more than one search option at a time to speed up the search and make the retrieval more focused. Only those facilities matching all specified criteria will be retrieved.

Standard Industrial Classification (SIC) Search Option

SIC Code Description

Enter a complete or partial SIC code description to obtain a list of all SIC Codes that fit under the description. For example, entering "metal" will retrieve all facilities with SIC Codes that have "metal" somewhere in the SIC description. A partial string may be entered for the SIC Code Description.

SIC Search

Enter a four-digit SIC Code. The first two digits define a major business sector, and the last two digits denote a facility's specialty within the major sector.

Note: If both SIC Code and SIC Code Description are entered, only SIC Code will be used in the search.

North American Industry Classification System (NAICS) Code Search Option

NAICS Code Description

The North American Industry Classification System (NAICS) Code(s) that best describe the business activities conducted at a facility or establishment. NAICS codes are 6 digit numbers used by the Bureau of Census as part of a system to categorize and track the types of business activities conducted in the United States.

The individual digits within the NAICS code indicate different levels of granularity in identifying a business. Here is an example of the granularity the individual digits provide:

No. Example
Digits NAICS Definition / Granularity
- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
Two 31xxxx Manufacturing
Three 311xxx Food Manufacturing
Four 3115xx Food Manufacturing, Diary Products
Five 31151x Food Manufacturing, Diary Products, (Not Frozen)
Six 311511 Food Manufacturing, Diary Products, (Not Frozen), Fluid Milk

A facility may be comprised of one or more establishments. An establishment is an economic unit, generally at a single physical location, where business is conducted or where services or industrial operations are performed. Each establishment may have a unique NAICS code.

Chemical Search Option

Chemical Name

Enter a complete or partial chemical (parameter) name. There can be various common names for the same chemical, so if the name you enter is not listed under that name for the facility, the TRI search will not retrieve a facility that you might want to see.

Chemical Abstract Service (CAS) Number

Use the "Lookup Pollutant codes and CAS numbers" link to look up a CAS Number, or enter the chemical's CAS Number in the field.

Search Values Option

Click on "Use Multisystem facility information to perform facility search" to identify facilities, using facility information from all program systems. Click on "Use TRI facility information to perform facility search" to identify facilities, using only TRI facility information.

Usage Constraints

Information in the TRI database can be freely accessed through the use of this search. The complexity of the search is up to the user. Searches that return a large volume of data may terminate prematurely due to system limitations. Develop searches that return small batches of data and terminate the session as soon as the searches have been executed, so that others can access the database.
