Request Management Support System data on imports and exports

Find out how to request and buy Management Support System data from HMRC if you're a company that imports or exports goods.

When a customs audit takes place, HMRC holds records of actual data entered and raises assessments on duties for imports not recorded in the trader’s records but actually declared to customs. This can happen when an agent fails to make a correct declaration.

It’s your responsibility to correctly declare goods and only negligible liability is placed on your agent. Larger traders with multi-site operations can find it difficult to keep records of imports due to the number of different locations and agents.

The Management Support System (MSS) data helps simplify and improve the accuracy of your records. For example, by giving accurate figures for the total amount of duty paid against value of goods entered.

What information is in a report

There are 4 standard reports available, covering:

  • import item
  • import entry
  • import tax lines
  • export item

The import and export item reports should meet the needs of most HMRC customers.

The reports are sent to a named responsible person in your business and include:

  • entry date
  • commodity code
  • Customs Procedure Code
  • value of goods and tax paid
  • others items of data

Not all data items on the MSS can be purchased in the reports. There is information on the system which cannot be released because it could compromise HMRC control activities.

Minimum sign up for monthly and one-off reports

You can request both ongoing and one-off reports.

If you request ongoing reports, you must sign up to receive them for a minimum of 12 months. For example, if you sign up in January 2018, you will receive ongoing reports from January 2018 to December 2018. Backdated requests cannot be accepted.

After 12 months, you’ll be sent a renewal email notification and invoice for you to sign up for another 12 months. If you do not want to renew, Email:

You can request one-off retrospective reports, as long as the requested report period is within the last 4 years.

How to request a report

If you’re a trader

Send the completed MSS Agreement (PDF, 206 KB, 12 pages) and a covering letter to the MSS Team at Email:

Use this MSS Agreement checklist (PDF, 133 KB, 2 pages) to make sure your application is correct and includes all needed information.

Covering letter

You must include a covering letter which:

  • is on company headed paper
  • is signed by the authorised person
  • has the dates or month the applicant requires historic or ongoing data to cover or begin
  • uses the standard wording in Schedule D, page 10, of the agreement including the information in the square brackets and relevant wording in the curly brackets


You must complete each page of the agreement.

Page 1 should include the:

  • same dates as the covering letter
  • applicant or third party company name

    • the applicant or third party applicant (if relevant)
    • data recipient (if different to either of above)

Page 3 should include:

  • any additional requested information or show ‘n/a’ if not requested
  • all the attached documents are to replace all the versions currently published

How the data is sent to you

Reports are sent by email to the nominated representative, normally as an Excel spreadsheet.

If you agree to receive the reports by email, HMRC will not be responsible for the security of the information once it has been sent to you.


  1. A single Standard Report will be provided by the client for the agreed duration of the agreement, at a cost of £240 plus VAT per VAT registration per year.

  2. Any additional Standard Reports will be provided at an additional cost of £240 plus VAT per VAT registration per year for each report.

  3. A purchaser who requires 4 separate Standard Reports for a single VAT registration number would have to pay £960 plus VAT per year.

  4. For each different VAT registration held, where the purchaser requires a separate monthly Standard Report, a separate charge will be levied. Therefore if the purchaser requests single monthly reports on 4 different VAT registrations the cost of that data for a year would be £960 plus VAT per year. However, the purchaser can elect to receive a single Standard Report containing details of all the separate VAT registrations, the cost of that data for a year would then be £240 plus VAT.

  5. Data will be provided each month from the point of acceptance to the scheme.

  6. Should the purchaser require a separate report that deviates from the Standard Report then this will represent a non-standard enquiry, which will be chargeable at a rate of £423.75 plus VAT per year for each VAT registration monthly report.

  7. Additionally, should the purchaser require a Standard Report for historical data before the date of sign up, then this report will be charged at a rate of £240 plus VAT per year. The maximum amount of historical data available is 4 years and the maximum charge is therefore £960 plus VAT per year.

  8. Non-standard reports of historical data are also available at a rate of £423.75 plus VAT per year.

  9. Where reports are requested for a period covering less than 12 months charges will be applied at a pro-rata monthly rate of £20 plus VAT for Standard Reports and £35.31 plus VAT for Non-Standard Reports.

Customs warehouse reports

EORI number reports

EORI reports help traders that, before EORI, were issued Traders Unique Reference Numbers (TURN) with separate suffixes, to identify branches that are not themselves legal entities.

The reports list entries made by the trader where a header additional information statement starting with ‘BR’ (or ‘AG’ if the trader is acting as a declarant or representative) is entered in Box 44. If no such code is entered the entry will not appear on the reports.

The reports are to help reconciliation, in particular against:

  • C79s
  • duty deferment statements

Complete the EORI report form to request a report.

How to identify branches or divisions

Some Economic Operators use TURN to help identify imports or exports and revenue due against individual branches or divisions.

As branches or divisions do not qualify for an EORI number, this may cause problems for Economic Operators set up in this way.

HMRC has 2 processes in place which may help associate declarations to individual branches or divisions.

Option 1

HMRC has set up 2 Additional Information (AI) statement codes at header level in box 44 of the C88 declaration to identify the branch importing, exporting or acting as declarant when a customs declaration is made. These codes are:

  • BR followed by a 3 digit numeric code for importers or exporters
  • AG followed by a 3 digit numeric code for agents or declarants

It’s likely the 3 digit numeric code used will be the same as the current TURN suffix but you’re free to choose any number you want. Both codes can appear on the same declaration if necessary.

You do not need to tell customs the numbers you’ve chosen to identify your branches. However, you’ll need to keep records and provide this information to HMRC, if requested.

Four new EORI reports are available to importers, exporters, agents or declarants on a monthly basis:

  • BR imports
  • BR exports
  • AG imports
  • AG exports

They list all entries made where the BR or AG code has been entered in box 44, in particular against C79s. If no code is entered in box 44, the entry will not appear on the report.

The report includes:

  • the entry number
  • date
  • EPU
  • declaration unique consignment reference (UCR)
  • master UCR
  • agent’s reference
  • BR or AG code in box 44

Reports will normally be sent within 15 working days of month end (for imports) and between the 15th working day and the end of the month following submission of the entry (for exports).

Option 2

This solution is for importers only.

Add your 3 digit branch identifier number as part of the agent’s reference in box 7 of the C88 customs declaration, for example TGR12867498/002 or 001 - FWAYU561829.

As box 7 of the declaration also appears on the C79 (a form detailing each month all your imports where VAT has been charged) this may help reconciliation of your imports against branches and may be used with or instead of the MSS report detailed above.

Contact the MSS team to sign up for EORI reports.

This team is not responsible for issuing EORI numbers.


There is no charge for the EORI report.
