Diamond Sawblades — South Korea — A-580-855

A trade measure labeled “Diamond Sawblades” and identified as AD/CVD concerns antidumping (AD) and countervailing duties (CVD). Antidumping duties address imports that the government determines are sold in the United States at unfairly low prices. Countervailing duties address government subsidies that benefit foreign producers or exporters. These duties are separate from ordinary customs duty and may apply in addition to it.

The measure typically affects US importers, foreign exporters, manufacturers, and sometimes related parties involved in covered diamond sawblades. The key issue is not only the product’s marketing name, but its tariff classification, physical characteristics, country of origin, and the identities of the producer and exporter. An importer may be responsible for declaring the goods correctly and paying any applicable cash deposit or later-assessed duties. AD/CVD scope and applicability can be technical, so confirm uncertain cases with official instructions or a qualified customs broker or trade counsel.

What to check

• Read the measure’s scope language and compare it with the product’s construction, dimensions, use, components, and packaging—not just its commercial name.
• Confirm the applicable Harmonized Tariff Schedule (HTS) classification, but do not assume an HTS number alone proves that the product is covered or excluded.
• Verify the country of origin, manufacturer, exporter, and any trading or related-party arrangements; AD/CVD treatment can depend on these details.
• Check official entry instructions for required cash deposits, certifications, liquidation treatment, and importer-of-record responsibilities before shipping.
• Request a formal scope ruling or professional customs advice when the product is borderline, modified, bundled, or described by an exclusion.
