Dynamic Random Access Memory Semiconductors — South Korea — C-580-851

“Dynamic Random Access Memory Semiconductors” refers to DRAM products, a type of memory semiconductor that stores data temporarily and is used in items such as computers, servers, and other electronics. A US AD/CVD measure is a trade-remedy action: antidumping (AD) rules address imports sold at less than fair value, while countervailing duty (CVD) rules address imports that benefit from certain government subsidies.

The measure typically affects US importers, foreign producers and exporters, and sometimes related parties involved in selling or assembling the covered merchandise. Its scope—not just the product’s marketing name—determines whether a shipment is covered. Importers may need to pay additional duties, provide accurate entry information, and maintain records supporting the product’s classification and origin. The importer of record is generally responsible for entry compliance, even when another party arranged transportation or customs filing.

What to check

• Read the measure’s official scope description carefully, including technical characteristics, exclusions, and product forms; do not rely only on the product name or tariff classification.
• Confirm the product’s HTSUS classification and compare it with the scope. An HTSUS number can help identify merchandise but usually does not control the legal scope by itself.
• Check the manufacturing country, exporting country, producer, exporter, and any related-party involvement, because AD/CVD treatment can depend on these details.
• Ask your customs broker or trade counsel to verify the applicable AD/CVD case information, cash-deposit instructions, and entry documentation before importation.
• Keep product specifications, invoices, bills of materials, origin records, supplier certifications, and scope-analysis notes so you can support the classification and coverage decision.
