Why does this matter to me?
It’s important that businesses are aware that this change is happening in order to avoid any unwanted delays or repercussions and remain HMRC compliant when their customs declarations are submitted to HMRC via CDS.
CHIEF vs CDS
The incumbent HMRC system used for customs declarations is being taken out of service and replaced. Where entries are done on behalf of international trading businesses by brokers or freight forwarders this will not cause a change to their overall operational processes. The new system is different and will require some additional information to complete the customs declaration.
The current system used by HMRC for customs declarations; Customs Handling of Import and Export Freight (CHIEF) system, which has been in use since 1994, is being replaced by the Customs Declaration Service (CDS) system.
The current deadlines for the phasing out of CHIEF being available advised by HMRC are 30 September 2022 for imports and 31 March 2023 for exports. Following this CHIEF will cease to operate and the only available system will be CDS.
Why the change?
HMRC are changing the customs declaration system to modernise the customs process as CHIEF entries are based on paper submissions and include several boxes that accept data in a free text format. The CHIEF system was also not designed to manage the volume of customs entries that are now made, and CDS has been designed to ensure that there is a robust system in place that provides a more futureproof solution to increased volumes.
CDS, has been built around data processing rules. As such, most data elements will be restricted to code format other than name and address fields. This means that a higher level of specificity is required, and therefore creates a greater need for accurate details to be provided.
HOW CDS Differs to CHIEF
With this new system, there will come a number of changes that businesses trading internationally should be aware of. These changes will affect the level and type of information that will be requested from you by your Customs Broker.
Data Groups and Data Elements
When making declarations, what are currently known as boxes in CHIEF are being replaced by data elements in CDS. While similar in function they are not like for like, and there will be more data elements required to fill out in CDS than there currently are boxes in CHIEF.
Data elements are categorised into eight data groups. The data group number is used in the identification of the data elements, as an example for dispatch country detail CHIEF box 15 is data element 5/14 in CDS (for data group 5 data element 14). The groups are not necessarily consolidated together in one area on the C88.
| Group | Description | Additional detail |
| 1 | Message information (including Procedure Codes) | Technical information for HMRC eg entry status such as pre-lodged import. The PCs and APCs for the consignment. |
| 2 | References of messages, document, certificates and authorisations | UCR number Licences as required by the commodity code. Authorisation details as dictated by PC and APCs. Proof of origin details if preference is being claimed for duty and VAT reductions. |
| 3 | Parties | Details of the parties involved in the consignment’s movement including: Exporter, Importer Declarant, Representative as well as Buyer and Seller. VAT and EORI numbers. |
| 4 | Valuation information and taxes | Includes incoterms, invoice value, additions and deduction values for items such as transport costs. |
| 5 | Dates, times, periods, places, countries, and regions | Includes dispatch country, destination country, origin country and preference origin country. |
| 6 | Goods identification | Includes package details, commodity code, net and gross weights. |
| 7 | Transport information (modes, means and equipment) | Includes transport details such as vehicle registration number, trailer number, container number and type of transport across the border. |
| 8 | Other data elements (statistical data, guarantees and tariff related data) | Includes financial details such as guarantee type and reference or cash account details if required and type of transaction such as out right sale or financial leasing. |
Additional fields for completion:
- For import declarations made in CHIEF, up to 68 boxes are typically completed, with 45 boxes completed for export declarations.
- In CDS, there will be 91 data elements used across import and export declarations. A subset of 76 data elements may need completing for imports, and 65 for exports, depending on what use the goods are being put to.
A single box in CHIEF can contain several pieces of information; in CDS, the same information may now be separated into specific data elements. For example, box 14 for declarant representative on a CHIEF entry is now made up of 5 data elements on CDS.
CDS also has a mandatory requirement for both net and gross weight of commodities to be entered and therefore both will need to be supplied for every commodity.
Incoterms
Whereas CHIEF only required the letter abbreviation of the incoterm being used for the movement of a consignment. CDS requires the full incoterm to be stated including the named location including country that joins the three letter term for DE 4/1. For example, for an export consignment on FCA terms arranged for collected by the customer on the exporter’s premises in Middlesbrough, that business will need to declare for CDS FCA Middlesbrough, UK or if the terms were CFR for Fremantle, they would need to confirm CFR Fremantle, Australia. An importer on DAP terms to their warehouse in Gateshead would need to state on DAP Gateshead, UK on their declaration instructions.
Customs Procedure Codes
One of the most significant changes to be aware of on CDS will be to do with customs procedure codes (CPCs).
CPCs are used to inform HMRC of the reason for the import/export and identify which Customs regime the goods will enter, such as free circulation or Inward Processing. The CPC also informs HMRC when duties and VAT are to be collected.
On CHIEF, CPCs are comprised of a 7-digit code for each goods item.
On CDS, codes will be split into two parts; a single 4-digit Procedure Code (PC) combined with up to 99, 3-digit Additional Procedure Codes (APCs) for a single goods item.
Much like the changes coming to data elements as detailed above, there is not always a direct conversion between CPC codes on CHIEF, and PC/APC codes on CDS. This is because CHIEF CPC codes are unique to a goods item whereas CDS PC/APC codes make multiple, interchangeable combinations possible that allow a number of circumstances to be represented.
It is the responsibility of the business to provide the relevant PC and APCs for each commodity on every consignment for all customs declarations. Businesses need to familiarise themselves with these new PC/APC codes. Links to HMRC guidance on these new codes can be found via the following links:
- CDS Procedure Codes
- CDS Additional Procedure Codes
- Export PC – APC Correlation Matrix
- Import PC-APC Correlation Matrix
*The Correlation Matrices can be used to check which APCs can be used with each PC.
Commodity Codes
Whilst the UK trade tariffs for both CHIEF and CDS were updated at the beginning of 2022 in line with changes made by the World Customs Organisation (WCO). Requirements including for licencing for the same commodity codes in CHIEF and CDS can be different in some instances. Businesses are therefore advised to check the CDS tariff requirements for commodity codes before arranging a CDS declaration. The tariff can be found here.
Getting Access
All traders will need to register for CDS, this can be done via logging into the trader’s Government Gateway Account, where the following pieces of information will need to be provided:
- Your EORI number that starts with GB (if you do not have an EORI number starting with GB and are a UK based business, you must apply for one here)
- Your Unique Taxpayer Reference (UTR)
- The address for your business that matches HMRC’s Customs records
- Your National Insurance Number (for individuals or sole traders only)
- The date you started your business
- Your email address
Once registered for CDS via the Government Gateway traders will be able to view their Financial Dashboard and use the Secure File Upload Service. This will allow supporting payments to be made and supporting documents will be able to be submitted to HMRC such as licenses or certification where required.
Real time account balances and limits can be seen via the Financials page. Limitations are that it will not be possible to view historical transactions against the account.
Changes to payment methods for CDS
Duty Deferment Accounts
To use Duty Deferment Accounts in CDS existing account holders must complete a new Direct Debit Instruction. Original Direct Debit instructions for CHIEF should not be cancelled.
Whilst CHIEF and CDS are both in operation it will be necessary to have two active HMRC Direct Debit Instructions, one for CDS and one for CHIEF, payments for both will be taken on the same day. Separate statements for each account will be issued. This ensures that whilst both systems are operational entries can be made via either system as required.
In CDS deferment account holders will have the option of making interim payments against their deferment account to increase their available balance. This will provide the flexibility to increase the value of declarations in a given month without needing to increase agreed guarantees or limits. Further information is available here.
Any traders using an intermediary to clear goods through UK Customs will need to inform their intermediary of their payment preferences prior to the goods arriving in the UK. Where available as a service, intermediaries will still be able to arrange payment of any VAT and duty via their own Deferment Account on behalf of a trader where agreed by the two parties.
New payment methods on CDS
Flexible Accounting System to become Cash Accounts
The method currently used with CHIEF for payment of VAT and any duties at the time of import clearance will close. The Flexible Account System (FAS) will be replaced by Cash Accounts in CDS. When traders will be automatically issued a Cash Account when they register for CDS. Cash accounts will be managed through the Traders Government Gateway account. When payment is required for a clearance, the Trade will need to ensure that the account has the necessary funds in. Via their Government Gateway account traders will be able to:
- Top them up and use them to pay duties due for your goods when at the time the declaration is made
- Authorise their agents to use the accounts on their behalf
- Use their account in all Customs locations
- Allocate funds for declarations to clear against, in chronological order
- Withdraw funds from the Cash Account
Further information on paying funds into your CDS Cash Account can be found here.
Traders can view their Cash Account and manage who has permission to use it from the menu option ‘view your customs financial accounts’, which can be accessed via their Government Gateway account.
Immediate Payments
There will also be an option to arrange immediate payments to HMRC for VAT and duty, it will require the import customs clearance reference for that specific clearance to be known at the time of payment.
There are a variety of methods of payments available include CHAPS, BACS, online or telephone banking and debit or corporate credit card.
The 12 digit clearance reference number which will be prefixed with CDSI must be used in conjunction with the correct HMRC bank account details for CDS and the chosen payment method to ensure that the payment is correctly allocated.
Further details on immediate payment options, payment value thresholds and fund clearance timescales can be found here.
Guarantees
If goods are entering a customs special procedure an individual guarantee or a custom comprehensive guarantee may be required. The guarantees are usually required to allow the goods to enter a customs special procedure regime and permit duty to be deferred.
If a traders has a General Guarantee account, permission must be given via the ‘View your customs financial accounts’ on the CDS area of their Government Gateway account to give authorisation for brokers acting on their behalf. General Guarantee Accounts can be used as a combined method of payment with Duty Deferment Accounts.
Further details on General Guarantee accounts is available here.
Where an individual guarantee is used on CDS, it will be possible to use more than one individual guarantee per declaration. The guarantee along with the MRN from the declaration along with the payment reference number will need to be sent to HMRC.
Additional information is available on individual guarantees here.
CDS output document
The output document from CDS will still be called a C88. The C88 generated by CDS will be in a slightly different format to the C88’s generated by CHIEF, due to the changes and additional data fields to be shown on the C88. It will contain all details of VAT and duty costs, unlike CHIEF where additional documents are issued (H2 and E2) to confirm these details.
As with the CHIEF C88, CDS C88’s must be retained as your record of the declaration. HMRC’s requirements for archiving international trade documentation is available here.
Chamber CDS Service and Help
The Chamber has a wide range of services to support businesses with their international trade. The chamber’s ChamberCustoms Brokerage Service and Export Documentation Service are provided by a dedicated team based locally.
ChamberCustoms, the British Chamber of Commerce (BCC) network of agents, are early adopters of CDS and were the first to submit an export declaration via CDS and have been submitting import entries via CDS since November 2021.
