Requirements for Manifesting

Per Title 30, Texas Administrative Code, Section 335.10 , Texas requires use of the EPA’s Uniform Hazardous Waste Manifest (referred to as “manifest”) for hazardous and Class 1 wastes.

Texas regulations allow hazardous and Class 1 waste handlers the choice of using paper manifests, electronic manifests (e-manifests), or a hybrid of the two.


The EPA established a national electronic system for tracking hazardous waste shipments known as “e-Manifest” beginning on June 30, 2018. Visit the EPA’s e-Manifest webpage and frequently asked questions page for more information about the system.

See the EPA’s fact sheets for each kind of waste handler:

Contact EPA Region 6 for questions about e-Manifesting, including site manager permissions.

How do I Submit Manifests?

The TCEQ does not require submission of a copy of the manifest. The waste generator originates the manifest, keeping a copy for his records. The remaining copies of the manifest stay with the waste throughout transit to the final destination. The transporter and disposal facility sign the manifest, and a copy is returned to the generator.

The definition of “User of the electronic manifest system” in Title 40, Code of Federal Regulations, Section 260.10 may require receivers of hazardous and Class 1 wastes to submit manifests to EPA and pay fees for each manifest submitted.

Texas Waste Codes

Texas has 8-digit waste codes that identify each waste stream. Enter the Texas Waste Code in the blocks in Item 13 on the manifest for both hazardous and Class 1 Industrial waste. Use two of the 6 waste code blocks in Item 13 for the Texas Waste Code on paper manifests. For hazardous waste on paper manifests, enter up to 4 applicable EPA codes (e.g., D001, F001, etc.) in the remaining waste code boxes. Electronic manifests allow for the Texas Waste Code and an unlimited number of applicable EPA codes.

The formula for the Texas Waste Code is:
The 4-digit sequence number + the 3-digit form code + the 1-digit classification code.

Texas Waste Codes should have one of the following sequence codes:

  • a sequence code uniquely associated with a solid waste registration, or
  • a unique sequence code assigned for an unregistered episodic notification within the past 60 days.

If the waste does not have a sequence code as noted above, use the appropriate sequence code listed below:

  • CESQ- for waste from generators who are not subject to the registration requirements in 30 TAC 335.6(c) or the episodic notification requirements in 30 TAC 335.60 .
  • HOUS- for household hazardous waste from a household hazardous waste program.
  • OUTS- for class 1 or hazardous waste (not universal or household hazardous waste) generated outside of Texas.
  • PHRM- for hazardous pharmaceutical waste received from healthcare facilities (both in-state and out-of-state) as defined by 30 TAC 335.751 .
  • RRCT- for Class 1 or hazardous waste generated at facilities subject to regulation by the Railroad Commission of Texas.
  • TSDF- for waste subject to 30 TAC 335.503(b)(8)
  • UNIV- for universal waste

For instance, if a registered generator uses sequence number 5555, the form code for the waste is 001, and the waste is hazardous, the Texas Waste Code would be 5555001H. The rules corresponding to this formula can be found in 30 TAC Section 335.501 – 335.521 .

See the Guidelines for the Classification and Coding of Industrial and Hazardous Wastes (TCEQ Publication RG-022) for more assistance with the Texas Waste Code.

Do I use the Texas Registration Numbers or EPA ID numbers?

If one or more hazardous wastes are being shipped, enter the EPA ID numbers for the generator, transporter, and receiver. If no hazardous waste is being shipped, manifests can have either:

  • the 5-digit Texas solid waste registration numbers with “TX” in front of the registration numbers (e.g. TX88888) for the generator and the transporter, and the EPA ID for the receiver, or,
  • if available, the EPA ID numbers for the generator and the transporter, and the EPA ID for the receiver.

Exception Reporting

Generators must submit an exception report if they do not receive a signed copy of a manifest back from a receiver/designated facility within the timeframes in the table below.

Generator category

Waste Type(s) on manifest


Large Quantity Generator


45 days

Small Quantity Generator


60 days

Any registered generator

Class 1 Industrial only, no hazardous

60 days

Unregistered generators

Hazardous or Class 1 Industrial

Not applicable, no exception reporting requirements

Submit exception reports via a letter with the following information:

  • Solid waste registration number
  • Signature of the generator or authorized representative of the generator
  • Explanation of the efforts taken to locate the waste and the results of those efforts

Include a copy of the manifest with the letter. Send the exception report via:

  • Postal mail to
    Registration and Reporting MC-129
    PO Box 13087
    Austin, TX 78711-3087
  • Or fax to 512-239-6410

How can I Obtain Paper Manifest Forms?

To order paper manifests, contact a registered printer . Only registered printers may print and distribute paper Uniform Hazardous Waste Manifests. Contact EPA to become an approved registrant to print manifests.
