What is a Core Charge?
A core charge (also called "core deposit") is similar to the deposit you might pay for a can or bottle of soda and is a standard requirement in the auto parts industry. For example, in many states, to promote recycling, you pay a deposit when you purchase a can of soda and receive your deposit back when you return the empty can. Many automotive parts have a core charge, or core price, that works in essentially the same way as a soda can deposit.
30 Day Core Charge Hold
You authorize Tamerx Diesel Products, to hold your credit card for the specified core charge amount and that you agree to return your core with 30 days of receiving the purchased part. When we have received your core return, the hold is released and the core charge payment is canceled.
The customer, or parts buyer, is responsible for any shipping costs associated with core returns unless otherwise specified in the product listing/detail page. Tamerx Diesel Products offers prepaid UPS shipping labels (SKU numbers UPS-CR1 and UPS-CR2) for use in returning your core that are available for purchase on our website during your shopping/order process.
The shipping label you will need to use for the core return is dependent upon what part you are purchasing. UPS-CR1 is good for cores weighing up to 20 pounds. UPS-CR2 is appropriate for shipping cores weighing 21 pounds or more. You must include enough information with the core return that clearly identifies it as a.) a Core Return, and b.) contains enough information we can use to clearly associate the core return with your order. Including a copy of the invoice or packing slip that came with the original shipment, clearly marked "Core Return", is ideal. Alternately, you can include a note marked as "Core Return" that includes your order number, full name and address, and phone number or other contact information. Failure to include this information with your returned core will most likely delay any due core credit being issued and/or delay any applicable warranty activation. Core returns need to be for the exact part purchased and cannot be damaged. Substituting another part in place of the part you have purchased is not acceptable.
All fluids must be drained.
If you have purchased a set or a parts package, you will need to return cores for all components of the set. For example, if you have purchaed a high pressure oil pump with an IPR valve, you will need to return both HPOP and IPR valve cores to receive proper credit. If you have purchased an EGR cooler/EGR valve package, your core return must consist of an EGR cooler core and an EGR valve core, or core credit will not be given.
Core Charges are often mandated by state legislature, and, as such, the actual core charge and taxes on the charge may vary depending on the state in which you buy your part. The Tamerx Diesel Products core charge presented to you online today with your item is representative of the most common core charge.
Designed for 2008–2010 Cummins diesel platforms, the ISM and ISL DOC is a critical component of the exhaust aftertreatment system. This diesel oxidation catalyst is engineered to fit Cummins ISM and ISL engines, ensuring compatibility with factory exhaust layouts and emissions sensors. It functions by converting hydrocarbons and carbon monoxide in the exhaust stream into less harmful gases, supporting emissions compliance for these model years. Reliable DOC operation helps maintain proper exhaust flow and supports the efficiency of downstream aftertreatment components. This page provides application-specific details for the Cummins ISM and ISL DOC used in 2008, 2009, and 2010 vehicles, helping ensure accurate identification for service and replacement needs.

Yes, you can usually still drive if your DOC (Diesel Oxidation Catalyst) has gone bad, but it should only be considered a short-term option. Continuing to drive with a failing DOC can lead to downstream damage and more costly repairs.
A bad DOC affects how exhaust gases are treated and how heat is generated for the rest of the emissions system. While the vehicle may still run, problems tend to escalate over time.
What can happen if you keep driving with a bad DOC:
- Frequent or failed DPF regeneration
- The DOC helps create the heat needed for regeneration. When it fails, regeneration attempts may occur repeatedly or not complete at all, leading to rapid DPF loading.
- Persistent warning lights and fault codes
- Emissions or efficiency-related fault codes often remain active, even after resets, because the underlying catalyst issue has not been resolved.
- Abnormal exhaust temperatures
- A damaged DOC may cause uneven heat distribution or uncontrolled fuel oxidation, increasing the risk of thermal stress to exhaust components.
- Increased exhaust restriction over time
- Internal breakdown of the catalyst can partially block exhaust flow, resulting in reduced drivability and protective operating modes.
- Downstream component damage
- Prolonged operation with a bad DOC can shorten the lifespan of the DPF, sensors, and other exhaust components.
Short-distance driving may be possible, but ignoring a bad DOC increases the risk of compounded emissions system failures. If warning lights persist or regeneration issues continue, replacement should be prioritized to prevent further damage.
It is a diesel oxidation catalyst designed to chemically treat exhaust gases.
Exhaust flows directly into the catalyst housing from the turbo outlet piping.
Yes, it helps condition exhaust gases that support downstream regeneration activity.
Yes, it is a separate exhaust component positioned before the particulate filter.
