LS

For US customs, the country of origin is generally where the product was manufactured, produced, or grown—not the country it was shipped from, exported through, or purchased from. If production occurs in more than one country, origin may depend on the applicable substantial-transformation analysis, which considers whether processing created a new product with a different name, character, or use. The exact test can vary by product and trade rule.

In a tariff-measure tracker, “LS” is a measure-type label whose meaning should be confirmed against the page’s legend or official source. The country-of-origin field matters because duties, additional tariffs, quotas, exclusions, and other trade measures can be limited to goods originating in particular countries. Common mistakes include treating the shipping country as origin, relying only on the seller’s location, overlooking components or processing in multiple countries, and using one origin conclusion for every product without checking the relevant classification and rule.

What to check

• Confirm the product’s tariff classification and read the applicable origin rule for that classification and measure.
• Trace where the goods and their essential components were manufactured, produced, or grown; do not rely only on the export or shipping country.
• For multi-country production, document each processing step and assess whether the last processing substantially transformed the product; obtain broker or customs advice when unclear.
• Keep commercial invoices, bills of materials, production records, supplier origin statements, and other evidence supporting the origin conclusion.
• Check the tracker’s legend or official source to verify what “LS” means and whether the measure applies to the product’s origin, classification, entry date, or other conditions.
