  3. Adding product identifiers for the EU

Adding product identifiers for the EU

From November 1st, every item you ship into the EU must carry three additional product identifiers on its customs declaration. You most likely already have two of them. Here is how to add the one you probably don't.

What’s changing?

The European Union is introducing a new customs requirement under Commission Delegated Regulation (EU) 2026/1022. Every item sold into the EU must be declared with three separate product identifiers that enable EU customs authorities to trace an item back to both the seller and the manufacturer.

  • This new requirement applies to all 27 EU countries, and to every shipment regardless of value. There is no low-value exemption.
  • It applies per product, not per order. A five-item order will require five sets of identifiers.
  • You provide the product identifiers in Shopify or in the FlavorCloud product template. FlavorCloud sends them to the carrier and puts them on the customs paperwork.

What we need from you

Your product SKU: Already have it

Merchant Product Identifier (M‑PID)

In Shopify, we use the SKU already associated with each variant, so no action is needed. If you use the product template, enter each variant's SKU in the SKU column.

Manufacturer product reference: Needs to be done

Non-Standardised Manufacturer Product Identifier (NS‑PID)

This is a code defined by the product manufacturer, not the merchant. This is the key field that needs new data, and it’s required for every product variant with no exceptions.

Standardised product code: Confirm either way

Standardised Manufacturer Product Identifier (S‑PID)

An EAN, UPC, GTIN or ISBN, where the product has one. If it doesn't have one, set the code type to NONE. You cannot leave this field blank.

How to get started

There are two ways to provide your identifiers: directly in Shopify, or in the FlavorCloud product template. Start with step 1, then follow the option that fits how you manage your catalogue.

1. Find your manufacturer references

This value comes from your supplier rather than from your own systems. It is usually on:

  • The purchase order or commercial invoice from your supplier
  • The product spec sheet or tech pack
  • The carton or case label on inbound stock

If you manufacture your own products, your own internal product code will suffice. It's fine for it to be the same as your SKU in that case, as long as you're confirming that deliberately rather than copying it in to fill the box.

Option A: Add them in Shopify

A1. Create the fields in your Shopify store

These fields don't exist by default. You create them in Settings › Custom data. Create four metafield definitions, three on Variants and one on Products:

Create it on

Namespace and key

Name it

Type

Variants

custom.ns_manufacturer_pid

Manufacturer product reference

Single line text

Variants

custom.std_manufacturer_pid

Standardised product code

Single line text

Variants

custom.std_manufacturer_pid_type

Type of standardised code

Single line text, list of choices:
GTIN, EAN13, EAN8, UPC, ISBN, OTHER, NONE

Variants

custom.merchant_pid

Merchant PID override

Single line text

The namespace and key must match exactly. Shopify generates a key from the name you type, so open Advanced options when you create each definition and set the namespace and the key to the values in the table. If the entries are not identical, we will not be able to find your data and your products will report as not ready.


Additionally, choose Single line text, never a number type, because a number type will drop leading zeros. Create the manufacturer product reference on both Variants and Products, so you get the bulk-fill shortcut in step A2.


Creating them as definitions rather than ad-hoc metafields will make the fields appear in the variant editor, in Shopify's bulk editor, and in your CSV exports, which is how you will actually fill them.

A2. Add them in bulk, not one at a time

Manufacturer references are usually shared across sizes and colors of the same style. Set the reference on the product and every variant of it inherits the value e.g. 200 styles in 8 sizes means 200 entries, not 1,600. Only set it on an individual variant where the manufacturer explicitly references each size separately.


For large catalogues, use Shopify's bulk editor, or export your products to CSV, fill the column in a spreadsheet, and re-import it.

A3. Add standardised codes, or confirm there aren't any

If a product carries an EAN, UPC, GTIN or ISBN, enter it and pick the matching type from the dropdown. Enter the code exactly as printed, including any leading zeros.


If a product has no such code, leave the code field empty and set the type to NONE. EU rules require the absence of a code to be explicitly declared, so we need you to confirm it rather than infer it from a blank field. Once you have, we’ll make that declaration for you.


Do not invent a code and do not copy in the SKU. A wrong code is a false customs declaration, and a confirmed "no code" is entirely lawful.

Option B - Non-Shopify: Use the FlavorCloud product template

B1. Download the product template

Download the FlavorCloud product template. It includes every field we need, including all three product identifiers, plus example rows that show the correct format. Start preparing your file now.

B2. Fill in one row per variant

Each row in the template is one product variant. A style in 8 sizes gets 8 rows, each with the same Title and its own Variant Title and SKU. Delete the example rows before you add your own.

B3. Add standardised codes, or confirm there aren't any

Before you enter any codes, format the SKU, Manufacturer Product Reference and Standardised Product Code columns as Text. Spreadsheet apps like Excel treat long numbers as numbers and drop the leading zeros.


If a product carries an EAN, UPC, GTIN or ISBN, enter it in the Standardised Product Code column and enter the matching type in the Type Of Standardised Code column: GTIN, EAN13, EAN8, UPC, ISBN, OTHER or NONE. Enter the code exactly as printed, including any leading zeros.


If a product has no such code, leave the code column empty and set the type to NONE. EU rules require the absence of a code to be explicitly declared, so we need you to confirm it rather than infer it from a blank field. Once you have, we’ll make that declaration for you.

What happens if you leave a field blank

If this field is empty

What happens from 1 November

Manufacturer product reference

Your EU shipments for that product will be blocked. There is no exception for this field.

Standardised product code
type set to NONE

Nothing. We declare that the product has no standardised code, which is permitted and normal.

Standardised product code
left blank, not confirmed

Not a valid declaration. We cannot state that a code is absent unless you have told us it is, so the product reports as not ready.

Never type "N/A", "none" or "TBC" into the manufacturer product reference. 

Quick rules

  • One value per field. No lists, no separators, no notes like "see supplier sheet". Each field must contain exactly one identifier.
  • Ensure the Product ID lengths fit within the max character limits in the table below. Values that exceed these limits can be rejected, so ensure none of your IDs exceed them.
  • Type it exactly. Capitals, hyphens and leading zeros all matter. We pass the value through unchanged. Copy and paste directly wherever possible to avoid typos.
  • Plain characters only. Letters, digits, hyphens, full stops, slashes and underscores.

Field reference

Here are the exact field names and accepted formats for Shopify, API and template setups. All Shopify and API keys are from the flavorcloud namespace.

std_manufacturer_pid
std_manufacturer_pid_type

Standardised Product Code (Optional)
Type Of Standardised Code (Optional)

Always. Either the code with its type, or type NONE to confirm there is no code

Code: 8, 12, 13 or 14 digits, or 10 characters ending X.
Type: GTIN, EAN13, EAN8, UPC, ISBN, OTHER, NONE

EAN13
0012345678905

The SKU; an invented code; a stripped leading zero

Use a text type for every one of these fields, whether that's a Shopify definition or a spreadsheet column. A number type drops leading zeros and turns a valid code into an invalid one.

Before November 1st

The October 15th preparation target has passed. If you haven’t completed these steps, finish them now. From November 1st, EU shipments for any product without a manufacturer product reference will be blocked.

  • Shopify: the four fields are created, with the exact namespace and keys. Template: you've downloaded it and added every product you ship to the EU.
  • Every variant you ship to the EU has a SKU
  • Every one of those has a manufacturer product reference
  • Standardised codes added where the product has one, and the type set to NONE where it doesn't
  • No placeholders like "N/A" anywhere in the manufacturer reference field
