M-PID, NS-PID and S-PID — what they mean for an online seller
EU customs rules for distance sales of imported goods to consumers use three product identifiers (Regulation (EU) 2026/1022; Commission guidance §3.5.4). The names are clumsy; the idea is simple: who is selling it, who made it, and what universal barcode does it carry.
| Term | Plain meaning | Example | Required? |
|---|---|---|---|
| M-PID — merchant product identifier | The seller's or marketplace's own code for the listing | SKU TW-BGVL3-10, or a listing / variant ID | Yes |
| NS-PID — non-standardised manufacturer product identifier | The maker's, producer's or supplier's own reference, not based on a global standard | Model BGVL3-10-BLK, part number A-1042-BLK | Yes |
| S-PID — standardised manufacturer product identifier | A code based on an international standard | EAN-13 8858812345671, UPC, ISBN | Where one exists |
Y081
Y081 is the code a declarant uses to state that no standardised identifier exists for the item. It does not excuse a missing manufacturer code; it only covers the barcode field. A hand-made item with no barcode can be declared with Y081 — it still needs the merchant code and a maker's code.
Common mistakes
- Copying the barcode into the manufacturer-code field without asking. A maker may use its barcode as its own product code too (Commission guidance, section 3.5.4), but only the maker or supplier can confirm that, so record their confirmation.
- Using the vendor's name as the manufacturer code. It must be an item reference, not a company name.
- Reusing one barcode across different products. A barcode identifies one exact item.
- Leaving the SKU blank on some variants. Every shipped variant needs its own merchant code.

Questions
Can the SKU and the manufacturer code be the same value?
Only if you are the manufacturer and your SKU is genuinely your model reference. For resold goods they are different codes from different parties.
Is an Amazon ASIN an M-PID?
A marketplace listing identifier can serve as the merchant product identifier for sales on that marketplace. For your own store, use your SKU or variant reference.
Do variants need separate codes?
Yes for the merchant code. For the manufacturer code and barcode, the Commission guidance (section 3.5.3) describes each identifier as referring to exactly one product variant (same brand, size, colour, packaging), so each size or colour needs its own manufacturer code, and its own barcode where one exists. If a maker gives one code for several sizes or colours, ask the maker for a code per variant and record the answer.
