Within modern trade compliance frameworks, origin determination plays a central role in tariff eligibility, preferential access, and enforcement risk, requiring exporters to apply legal tests consistently across jurisdictions.

According to the World Customs Organization ‘Rules of Origin Handbook’, there are two types of origin determinations:

1. ‘Wholly obtained’: which means the goods origin naturally occurred, for example, a mineral was extracted in a single country, a live animal was born or raised in a given country, or a product was manufactured from wholly obtained material.
2. ‘Substantial transformation’: which means the product had to undergo a substantial or sufficient transformation. There are three ways that this can happen:

• Tariff shift: This is when there is a change in the tariff classification of the good after a transformation that it received in the country. For example, a company could import raw cocoa beans (HS 18.01) and process them into chocolate bars (HS 18.06). Depending on the degree of change, these shifts are referred to as ‘CC’ (change in chapter), ‘CTH’ (change in tariff heading), or ‘CTSH’ (change in tariff subheading).
• Ad valorem (value added): This rule determines origin based on the value of domestic content added during production. In other words, a product may qualify as originating if a specified percentage of its value is generated within the region. For example, a trade agreement might require that at least 45 percent of the value of a finished product come from originating materials or processing carried out within the member countries. If that threshold is met, the final product is considered originating, even if some non originating components are used.
• Technical requirement: The product must undergo substantial processing operations. For example, simply painting, polishing, or packaging a non originating item is generally not considered sufficient transformation to confer origin. These are viewed as minimal operations under most trade agreements. By contrast, if a company imports unassembled bicycle components (frames, gears, and wheels) and assembles them into a complete bicycle, this would normally meet the requirement for substantial transformation as the production results in a new product with a different function, use, and tariff classification.

Various free trade agreements’ legal definitions of production or substantially processed vary, so it is important for the trader to ensure their meaning is in line with their operations for a specific FTA.

For example, the definition for production in the PAN EURO MED FTA is ‘any kind of working or processing including assembly or specific operations’, whereas in the Trans Pacific Partnership Agreement it means ‘operations including growing, cultivating, raising, mining, harvesting, fishing, trapping, hunting, capturing, collecting, breeding, extracting, aquaculture, gathering, manufacturing, processing or assembling a good’, or in the UK EU Trade and Cooperation Agreement production is described as ‘any kind of working or processing including assembly’ (Article 38 Definitions).

What this means to the trader is that if origin is determined by substantial transformation and a specific FTA describes what it means by production or manufacture, the trader’s operations must be in line with the specific definition. For some FTAs, simple processing such as painting or repackaging of the imported product may not meet the definition of substantial transformation. Therefore, additional consideration must be given to how a company’s operations are defined and whether they align with the legal definitions.

Other considerations from the supply chain and operational standpoint that need to be aligned with the particular FTA are accumulation and cumulation rules. Cumulation allows businesses to treat materials from other countries named in the FTA, or countries linked via different FTAs, as originating when manufacturing a product that qualifies for preferential treatment.

There are three types of cumulation: bilateral, diagonal, and full. As defined by the WCO (Study on Cumulation, 2024), the main difference lies in the number of parties involved and what types of inputs, originating or non originating, can be used as the basis for cumulation. Cumulation not only simplifies origin rules for businesses, making it easier for products to qualify for preferential treatment, but also encourages regional economic integration among partner countries.
