What additional codes are
Goods are usually identified by their 10-digit commodity code.
Sometimes additional context is needed, beyond just the type of good identified by the commodity code, to ensure that the apporpriate tariffs and/or restrictions are applied, in these cases additional codes are used. Additional codes identify:
- whether a company is subject to punitive measures, such as anti-dumping duties
- products which have reduced duties because they are for pharmaceutical use
- the route goods take into the UK and how different tariff or regulatory treatments apply
- stolen works of art, for example from Syria or Iraq as a result of military conflict
Additional codes can be applied to more than one commodity code.
How additional codes work
Additional codes are 4 digits combining the following 2 elements:
- a code type
- a 3-character ID (which can also include letters)
The additional code type defines the additional code that is being addressed.
For example, the additional code C233 is made up of type C and specific ID 233.
Numeric IDs from 001 to 999 can be reused across multiple additional code type IDs. Numeric IDs are unique only when they are used with a character code.
The list of addional codes is frequently updated, with tens of new codes being added each year.

additional_code_types.description AS "Description",
CASE
WHEN application_code = 0 THEN "Export refund nomenclature"
WHEN application_code = 1 THEN "Additional codes"

The list of additional code types is set by DBT, and rarely changes as it requires extensive updates to downstream systems. The only changes in the last two decades have been the addition of code type C in 2009, and the end of code type F in 2016.
Applicability indicates the data type the additional codes apply to. Only those labelled “Additional Codes” are still in use, however the remainder still appear in the data and are included here for completeness.

Validation rules
Additional Codes
| Code | Description |
|---|---|
| ACN1 | Uniqueness for combination of fields additional code type, additional code ID and start date. |
| ACN13 | Validity contained rule requiring that when an additional code is referred to in a measure, the validity period of the code must span the validity period of the measure. |
| ACN14 | Deletion while in use for additional codes that are used in a measure. |
| ACN17 | Validity contained rule for the additional code type the additional code belongs to. |
| ACN2 | The referenced additional code type must exist and have as application code “non-Meursing” or “Export Refund for Processed Agricultural Goods. |
| ACN4 | Validity overlaps with self rule stating the validity period of the additional code must not overlap any other additional code with the same additional code type, additional code ID and start date. |
| ACN5 | Mandatory subrecord rule for additional code descriptions. The start date of the first description period must be equal to the start date of the additional code. No two associated description periods may have the same start date. The start date must be less than or equal to the end date of the additional code. |
| CT1 | Uniqueness rule for additional code types. |
Read the validation rules for additional codes in the system documentation.
How additional codes apply
Additional codes can only be applied to particular types of measures. For example, types 8, A, B and C can only be used with trade remedies. The full lists of measure types that can reference additional code types are shown below for each code type.
