Define transshipment and explain why it matters in tariff classification and duties.

• A. Transshipment refers to shipping goods directly from origin to final destination without any intermediate countries.
• B. Transshipment, a temporary suspension of duties at the border, is required for all shipments.
• C. Transshipment is the shipment of goods through a foreign intermediate country before final destination; it matters because the ultimate country of origin can affect eligibility for preferential tariffs, origin verification, and antidumping investigations.
• D. Transshipment is the act of exporting goods that have already been subject to duties in a previous country.

Answer: (C)

Transshipment means goods pass through a foreign intermediate country before reaching their final destination. This matters in tariff classification and duties because the origin used for tariff purposes depends on where the product is considered to originate under the applicable rules of origin. If the goods merely move through an intermediate country without undergoing substantial transformation, the origin may stay with the original country; if the intermediate country adds enough value or changes the product, the origin can shift. That shift affects whether the shipment qualifies for preferential tariffs, what documentation is needed for origin verification, and whether the product could be subject to antidumping investigations based on the country of origin. Customs will often require proof of origin, and the treatment at the border hinges on how origin is determined in light of transshipment. For example, a product made in one country, briefly processed in another, and then exported can have its origin debated, influencing duty rates and eligibility under trade agreements. This is why the defined concept and its impact on origin determinations are central.
