SZ

For US customs, the country of origin is generally where a product was manufactured, produced, or grown—not the country it was shipped from. In many cases, origin is determined by the last substantial transformation: the last processing that creates a new product with a different name, character, or use. Simple activities such as repacking, relabeling, or minor assembly usually do not change origin.

For tariff-measure tracking, “SZ” is the country code for Eswatini (formerly Swaziland). Measures may depend on origin because US rules can apply different tariffs, trade-program benefits, quotas, marking requirements, or other controls to goods from different countries. Do not assume that a shipment routed through, exported from, or invoiced by another country has changed its origin. Complex production chains, regional trade rules, and product-specific requirements may require a customs broker or other qualified professional’s review.

What to check

• Trace the product’s manufacturing steps and identify where the final substantial transformation occurred; distinguish that place from the export or shipping country.
• Check the applicable US tariff classification (HTSUS) and the origin rules or measure descriptions associated with that classification and country code.
• Collect and retain manufacturing records, bills of materials, supplier origin statements, production documents, and commercial invoices that support the declared origin.
• Verify whether processing in another country was more than packaging, relabeling, or minor assembly, and document why it did or did not change origin.
• Ask a customs broker or seek a formal customs ruling when production spans multiple countries or the origin analysis is uncertain.
