Customs product identifiers - M-PID, NS-PID and S-PID

The EU has introduced a requirement to provide product identifiers for goods imported into the EU. New attributes entries are now supported on objects in the customs.goods array, letting you declare them: m_pid (assigned by the seller or platform), ns_pid (a non-standardised manufacturer identifier) and s_pid (a standardised manufacturer identifier, such as an EAN or ISBN).

Product identifiers are accepted today for DHL Express, FedEx, UPS and unspecified-carrier shipments, with a couple of carrier-specific requirements. See Product identifiers (PID) for EU import for the full details.
