    Monosodium acid methanearsonate and cacodylic acid salts

Use K031 only when the waste stream and named Schedule 12 industry process both match.

By-product salts from making monosodium acid methanearsonate (MSMA) and cacodylic acid. A federal K source code.

Is Federal K031 hazardous waste?

Yes, if the listing and federal definition apply. Federal K031 is the federal listing for monosodium acid methanearsonate and cacodylic acid salts. The source, composition, concentration or test condition must match, and the exclusions in SOR/2021-25 still apply.

On a federally regulated international shipment, the applicant enters the waste classification in the waste-line details of the federal notification in CNMTS. The movement rules and exclusions apply.

What does Federal K031 cover?

By-product salts generated during production of monosodium acid methanearsonate (MSMA) and cacodylic acid. Both the waste form and its named generating step must match. A similar material from another operation isn't K031.

Official wording
By-product salts generated in the production of monosodium acid methanearsonate (MSMA) and cacodylic acid.

Is monosodium acid methanearsonate and cacodylic acid salts always Federal K031?

CodeWhen it fits
K031The waste is monosodium acid methanearsonate and cacodylic acid salts from the named Schedule 12 process.

Decide between these entries from the material's real origin, use, composition and test results. A shared chemical or process word doesn't make the codes interchangeable. The full listed condition and any federal exclusion still govern.
