Starting in March 2026, HMRC is handing UK businesses something they've never had before: free, direct access to their own customs declaration data. For the first time ever, you can see exactly what's been filed in your company's name, every tariff code, every duty payment, every single entry your customs agent has submitted on your behalf.
Here's the uncomfortable truth: most businesses have been flying blind, trusting their agents to get it right. And many haven't.
We're talking about overpayments, misclassifications, and errors that have cost UK importers thousands, sometimes tens of thousands, of pounds. The difference now? You can finally see it all for yourself.
What Is HMRC's Trader Request for Entry (TRE) Data?
HMRC's Trader Request for Entry (TRE) system is essentially your complete customs filing history. Every declaration made on your behalf since you started importing is logged in this database.
Until now, accessing this data came at a cost. Businesses either paid for expensive third-party data services or relied entirely on their customs agents to provide summaries, often incomplete ones. This created a power imbalance where agents controlled the information and businesses couldn't easily validate the work being done.
That all changes in March 2026. HMRC is making TRE data freely accessible to all registered importers. You'll be able to download your complete customs history, analyze it, and identify exactly where money may have been misspent or errors made.
This isn't just about transparency. It's about taking control of your customs compliance and making sure you're not subsidizing someone else's mistakes.
The Shocking Reality: Most Businesses Are Overpaying
Here's what we've discovered after auditing hundreds of customs declarations for UK importers: the majority contain at least one significant error or missed opportunity.
Common issues we find include:
- Incorrect commodity codes: Using the wrong HS code can result in overpaying duty by 5-15% on every single shipment. Multiply that across a year of imports, and you're looking at serious money left on the table.
- Missed duty relief schemes: Many agents don't bother claiming Returned Goods Relief, Inward Processing Relief, or other legitimate exemptions because it requires extra paperwork. You pay full duty when you shouldn't have to.
- Valuation errors: Declaring the wrong customs value, whether too high or too low, creates financial and compliance risks. Too high means overpaying; too low triggers HMRC audits.
- Origin documentation failures: Without proper proof of origin, you can't claim preferential tariff rates under trade agreements. Your agent should be managing this proactively, but many don't.
- Duplicate or ghost entries: We've seen cases where the same shipment was declared twice, resulting in double payment of duties that were never reclaimed.
These aren't theoretical problems. They're happening right now in thousands of UK businesses, hidden in data that was previously inaccessible or difficult to analyze.
The 2026 data gift changes that equation completely. For the first time, you have the power to audit your agent's work independently.
Why Manchester Customs Clearance Agents Need to Step Up Their Game
If you're working with a Manchester customs clearance agent or any customs provider in the UK, this shift should worry them, unless they've been doing excellent work all along.
Here's why: HMRC's expectations are rising in 2026. Audit activity is increasing, classification decisions carry heavier financial and reputational consequences, and businesses are no longer willing to accept "trust us" as an answer.
The agents who survive and thrive in this new landscape will be the ones offering:
- Proactive misclassification identification: Reviewing your data before HMRC does and fixing errors before they become liabilities.
- Tariff optimization strategies: Actively searching for duty savings opportunities rather than defaulting to the easiest commodity code.
- Compliance risk management: Building systems that prevent errors rather than simply reacting when HMRC comes knocking.
- Full transparency: Giving you access to your data in real-time, not hiding behind information gatekeeping.
If your current agent's primary value was controlling access to customs data, their business model just became obsolete. The question you need to ask is: what are they offering beyond data entry?
How to Conduct Your Own Customs Audit (and What to Look For)
Once you have access to your TRE data in March 2026, here's how to start identifying problems:
Step 1: Export Your Complete Declaration History
Request your full dataset from HMRC's TRE portal. You'll receive CSV or Excel files containing every declaration filed under your EORI number. This includes dates, commodity codes, duty amounts, origin countries, and declared values.
Step 2: Identify Patterns and Anomalies
Look for:
- The same product declared under different HS codes: This suggests inconsistency and potential errors.
- Unusually high duty payments: Compare your effective duty rate against the tariff schedule. Are you paying more than you should?
- Missing relief claims: Cross-reference your declarations against eligible duty relief schemes you should be using.
Step 3: Cross-Check Against Trade Agreements
If you import from countries where the UK has Free Trade Agreements (FTAs), verify that preferential rates are being applied. Many agents fail to utilize these agreements, costing you the difference between standard and preferential duty rates.
Step 4: Validate Commodity Code Accuracy
Take your top 10 imported products and verify their HS codes using HMRC's Trade Tariff tool. Even small classification errors compound over time into significant overpayments.

Frequently Asked Questions
What exactly is HMRC's TRE data and why does it matter?
TRE (Trader Request for Entry) data is your complete customs declaration history showing every filing made under your EORI number. It matters because it allows you to independently verify your agent's work, identify overpayments, and spot compliance risks before HMRC does.
When will HMRC make this data freely available?
HMRC is making TRE data freely accessible starting March 2026. Previously, businesses either paid for access or relied on incomplete summaries from their customs agents.
How do I know if my customs agent is overcharging me?
Common signs include inconsistent commodity codes for the same products, unusually high duty payments compared to tariff schedules, and failure to claim eligible duty relief schemes. A customs audit can reveal these issues definitively.
What is a customs audit and how does it work?
A customs audit involves reviewing your complete declaration history to identify errors, overpayments, and missed opportunities. At GCL, we analyze your TRE data, cross-check against tariff schedules and trade agreements, and provide a detailed report of findings and recommendations.
Can I reclaim duties I've overpaid in previous years?
Yes, you can submit reclaim applications to HMRC for overpaid duties, typically within three years of the original declaration. Our customs team manages this process for clients, maximizing recovery while ensuring compliance.
What's the difference between a freight forwarder and a customs agent?
A customs agent specifically handles customs declarations and compliance, while a freight forwarder manages the entire logistics chain including transport, warehousing, and customs. At GCL, we provide both services integrated into one seamless operation.
Why should I choose a Manchester-based customs clearance agent?
A Manchester-based agent offers local expertise, face-to-face support when needed, and deep understanding of regional supply chains: particularly important for businesses using Manchester Airport or surrounding distribution hubs for international trade.
What happens if HMRC finds errors in my customs declarations?
HMRC can issue penalties, demand payment of underpaid duties plus interest, and increase audit frequency for your business. Proactive auditing helps identify and fix errors before HMRC discovers them, protecting you from these consequences.
How often should I audit my customs declarations?
We recommend quarterly reviews for high-volume importers and annual audits for smaller operations. However, with HMRC's increased scrutiny in 2026, more frequent monitoring provides better risk management.
What is Shipflow and how does it help with customs management?
Shipflow is our digital platform that gives you real-time visibility into shipments, customs status, and costs. It centralizes all your trade data in one place, making it easier to monitor declarations, track compliance, and identify issues quickly.
