Oman

For US customs, the country of origin is generally where a product was manufactured, produced, or grown—not the country it was shipped from, exported through, or purchased from. For goods associated with Oman, check whether Oman is the true origin or only a transit, distribution, or consolidation location.

Origin matters because tariff measures, trade-program eligibility, quotas, marking rules, and special remedies can depend on the product’s origin. If production occurs in more than one country, customs may apply a “substantial transformation” analysis: the key question is whether processing in the later country creates a new product, with a different name, character, or use. Simple repacking, sorting, or relabeling usually does not establish a new origin, but the result can depend on the product and facts. Do not confuse country of origin with country of export or the location of the seller.

What to check

• Identify every country where the goods and their components were grown, produced, assembled, or substantially processed; do not rely only on the shipping or seller address.
• Review the applicable US tariff classification and origin rules for the product, because the analysis can differ by product type and tariff provision.
• Collect and retain manufacturing records, bills of materials, supplier origin statements, production descriptions, and invoices supporting the claimed origin.
• Check whether processing in Oman or another country was more than simple packing, labeling, or consolidation; obtain a customs broker’s or trade specialist’s advice for multi-country production.
• Compare the documented origin with the entry data, commercial invoice, marking information, and any measure-specific requirements before filing.
