Legal Standard
Origin rule used to determine the country of origin for a product that has been processed in multiple nations. The substantial transformation criterion requires that the material undergoes a fundamental change in name or use in the country where it is being finished. For linen, this involves the transition from raw flax fibre into spun yarn or from yarn into fabric.
Value Addition
Determination of origin is based on whether the processing creates a new and different article of commerce. Under the substantial transformation criterion, simple assembly or packaging does not count as a change of origin. In the context of Chinese mills, processing European flax into cloth is generally accepted as a sufficient change to label the fabric as a product of China.
The distinction is necessary for applying the correct tariff rates and following trade agreements.
Customs Verification
Authorities examine the production records and the costs involved to verify that the transformation actually occurred. If the substantial transformation criterion is not met, the product must be labelled with the origin of the raw material. Detailed documentation of every manufacturing step is kept to support these claims during a customs audit.
This rule ensures fairness in international trade.
