TRE Makes Customs Data Free: The Next Step in Data Transparency

For the first time, HMRC will provide free access to official customs declaration data through a new service called Trade Reporting and Extracting, or TRE. This is a significant shift for any business that imports or exports goods through the UK. Where obtaining your own declaration data previously required paid subscriptions and lengthy application processes, TRE removes those barriers entirely.

For compliance teams, finance departments, and supply chain professionals, this opens the door to routine oversight of customs activity without the friction and cost that previously discouraged it. Here is what you need to know about TRE, how it works, and why it should become part of your compliance toolkit.

From MSS to CDS

HMRC's original mechanism for providing traders with access to their own declaration data was the Management Support System, commonly known as MSS. MSS reports gave importers and exporters a way to review what had been declared on their behalf, though uptake was often limited due to the administrative effort involved.

As HMRC transitioned from the legacy CHIEF platform to the Customs Declaration Service (CDS), data reporting evolved alongside it. CDS introduced its own reporting functionality, designed to serve a more modern declarations environment. However, even under CDS, accessing your data still required formal applications and ongoing subscription fees.

The Launch of the TRE Service

HMRC has confirmed that CDS reports will be fully phased out, with all existing contracts expiring by 31 March 2026. In their place, the TRE service will become the sole mechanism for traders to download their official customs declaration data directly from HMRC.

This is not simply a rebrand. TRE represents a fundamental change in how HMRC makes data available, moving from a paid, application-based model to a free, self-service platform accessible through Government Gateway.

From Paid Applications to Free Access

Under the previous model, businesses needed to apply for individual CDS reports, each carrying an annual fee of £240 plus VAT. For organisations requiring full access across all four report types, the total cost reached £960 or more per year before VAT. On top of the cost, the application and renewal process added administrative overhead that deterred many businesses from obtaining their data at all.

TRE eliminates both of these obstacles. The service is entirely free and available to any trader with a valid Government Gateway account. This removes the financial justification for not reviewing your own customs data, and it means that businesses of all sizes now have equal access to the same official records.

Accessing TRE

To use TRE, you will need a valid EORI number and an active TRE registration linked to your Government Gateway account. Once registered, you can request and download your declaration data in either CSV or Excel format, with data typically available within 48 hours of a request.

One of the most practical advantages of TRE is that it consolidates information from both the legacy CHIEF system and the current CDS platform into a single data source. This is particularly valuable for businesses that traded during the transition period and need a unified view of their declaration history.

Why Using TRE Data Matters

There is a critical reason why every importer and exporter should be using TRE: HMRC conducts its post-clearance checks and audits against its own records, and TRE data is drawn from exactly those records. It is the definitive version of what was declared, regardless of what your broker or freight forwarder may have reported back to you.

If there is a discrepancy between what your agent told you was declared and what HMRC actually holds, it is the HMRC record that will determine whether you are compliant. TRE gives you direct visibility into that record, enabling you to identify and resolve issues before an audit brings them to light.

The Risks of Inaction

Choosing not to review your TRE data carries real consequences. Mis-declarations can go undetected for months or even years, accumulating financial exposure through incorrect duty payments, misapplied preferences, or wrong commodity codes. Overpaid duties represent cash that could have been recovered but was simply never identified.

Perhaps most critically, when HMRC does conduct a compliance check, the expectation is that you have been exercising reasonable care over your customs affairs. If you have had free access to your own declaration data and have never looked at it, that becomes a difficult position to defend. The absence of any internal review process suggests a gap in due diligence that auditors are trained to identify.

The Value of Routine TRE Use

Building TRE data review into your regular operations delivers benefits well beyond audit preparedness. It enables genuine internal audit capability, allowing you to verify that what your customs agents declared matches your commercial records, purchase orders, and shipping documentation.

For businesses that work with multiple brokers or agents, TRE provides a single consolidated view of all declarations, making it straightforward to compare performance, identify inconsistencies, and hold agents accountable. It also creates a documented trail of due diligence. Demonstrating that you routinely download, review, and act on your customs data establishes a strong foundation for any compliance enquiry.

Enhancing TRE with CAT360

TRE provides the raw data, but raw data alone does not tell you where the problems are. This is where CAT360 adds significant value. By ingesting your TRE downloads, CAT360 applies intelligent analysis to surface the insights that matter most.

CAT360's dashboards give you immediate visibility into declaration patterns, duty spend, and classification trends. Anomaly detection highlights entries that fall outside expected parameters, whether that is an unusual commodity code, an unexpected duty rate, or a valuation that does not align with your commercial records. Duty tracking ensures you know exactly what you have paid and where recovery opportunities may exist.

For businesses preparing for or responding to an HMRC audit, CAT360 provides structured, evidence-based reporting that demonstrates active customs oversight. Rather than scrambling to compile data when an audit notice arrives, you have a continuous, up-to-date picture of your compliance position.

The combination of free TRE data and CAT360's analytical capabilities means there has never been a more accessible or cost-effective way to take control of your customs compliance. The data is now available at no cost. The tools to make sense of it are ready. The only remaining question is whether your organisation will use them.
