Inorganic solids
Catalyst (reaction aid), inorganic solid

The material is nonpumpable rather than catalyst sludge.

Spent inorganic catalyst that is solid rather than sludge. Catalyst sludges take forms 493, 597 and 697 instead.

Where does Texas form code 393 go in the Texas waste code?

In characters 5–7. The 8-character code is a 4-character stream sequence, then the 3-digit form 393, then a class character. Form 393 describes the stream in the inorganic solids category. It says nothing about hazard. The class character depends on what the stream is made of, where it came from and its properties.

For a hazardous or Class 1 shipment that needs a Uniform Hazardous Waste Manifest, enter the full Texas code in Item 13, across 2 blocks on paper. Add any EPA waste codes. The 3 form digits alone are not enough.

The generator sets the class. Work through the exclusions, then the federal hazardous-waste listings and characteristics, then the Texas industrial-waste criteria. H means hazardous. 1, 2 and 3 are nonhazardous industrial classes. Process knowledge or testing backs the class. Choosing a form doesn't set it.

What does Texas form code 393 cover?

Catalyst waste that is nonpumpable and mainly inorganic. A catalyst speeds up a reaction and is not its intended product. Organic catalyst solids and pumpable catalyst sludges have their own forms.

Is catalyst waste Texas form code 393, 493, 597 or 697?

Code	When it fits
393	Nonpumpable, mainly inorganic solid catalyst waste.
493	Nonpumpable, mainly organic solid catalyst waste.
597	Pumpable, mainly inorganic catalyst sludge.
697	Pumpable, mainly organic catalyst sludge.

Record the catalyst material, how the process used it, its inorganic composition and its nonpumpable form.

Which wastes take Texas form code 393?

Waste	When it’s 393
Inorganic catalyst solids	Nonpumpable inorganic solid catalyst waste. Mainly organic catalyst solids use form 493 instead.
