Can "chief value" always determine the country of origin for customs purposes?

The concept of "chief value" refers to the idea that the country of origin for customs purposes is determined by where the value of the product originates most significantly. However, this determination can indeed vary for different types of goods. For instance, in some cases, the country where the final processing occurs may not be where the majority of the product's value is added, leading to a different conclusion regarding the country of origin.

Moreover, customs regulations can be complex and vary widely depending on multiple factors, including the nature of the goods, the manufacturing processes involved, and specific trade agreements. Therefore, what may apply to one product or type of good may not apply universally to all products. This variability makes it clear that while chief value is an important consideration, it does not always provide a definitive answer for every situation concerning the determination of country of origin.
