Application Identifier (AI) 422 specifies the country of origin of the product. A product’s country of origin is normally the country where the product was manufactured. It is often determined based on the proportion of the product’s components that were produced in that country. As there are multiple ways to define a product’s “country of origin,” it is recommended that the definition be agreed upon bilaterally between trading partners. It is the responsibility of the producer/manufacturer to ensure that the country of origin is correctly declared.
The country code to be used for the country of origin is defined in ISO standard 3166.
