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.


Serving as a vital part of the exhaust aftertreatment system, the Diesel Particulate Filter (DPF) for Cummins ISC engines is designed to capture soot and particulate matter from exhaust gases. This filter helps manage emissions by storing particulates within its internal structure until they are addressed through normal regeneration processes. Its emissions-rated construction supports proper fitment, consistent exhaust flow, and durability in high-temperature operating environments. When issues such as exhaust restriction, increased soot accumulation, or aftertreatment system alerts occur, replacing the DPF can help restore correct exhaust system function. Designed with durable materials and precise engineering, it provides dependable exhaust filtration for Cummins ISC engine applications.

The Diesel Particulate Filter (DPF) is designed to trap soot and release it through regeneration. Over time, ash accumulation and internal wear reduce its ability to function properly. While many DPF problems can be resolved through professional cleaning, there are clear situations where replacement is the safest option.

A DPF should be replaced when it can no longer regenerate effectively or when physical damage is present. Continuing to operate with a worn filter can cause exhaust restriction and place stress on other emissions components.

You should consider replacing your DPF when:

  • DPF warning lights return after cleaning
  • Regeneration cycles fail or occur excessively
  • Exhaust backpressure readings remain high
  • Ash load exceeds service limits
  • Cracks, melting, or internal damage are found
  • Vehicle enters derate mode repeatedly
  • No improvement occurs after diagnostics and service

Diagnostic scans help confirm soot load, ash accumulation, and regeneration history. If the filter has reached its service limit or suffered internal damage, replacement is the only reliable solution.

Replacing the DPF at the right time helps restore proper exhaust flow, protects the DOC and sensors, and prevents costly downtime.

The system uses exhaust temperature and pressure data to track restriction levels.

The filter must be removed and cleaned or replaced to restore exhaust flow.

Clean combustion reduces the amount of soot entering the filter.

Rising backpressure can indicate increased particulate loading.
