Oil Country Tubular Goods — South Korea — A-580-825

“Oil Country Tubular Goods” (OCTG) generally refers to certain steel tubular products used in oil and gas drilling and production, such as casing, tubing, and related products. The exact scope is controlled by the product description in the trade-remedy order, not just by a product name, marketing description, or tariff classification.

“AD/CVD” means antidumping and countervailing duties. An antidumping (AD) measure addresses imports that are found to be sold at less than normal value, while a countervailing duty (CVD) measure addresses benefits from foreign government subsidies. These measures typically affect importers of covered goods from specified countries, as well as foreign producers, exporters, and sometimes related parties. They matter because an importer may owe additional duties, must provide accurate entry information and documentation, and may face liability if the merchandise is incorrectly declared or the scope is misunderstood.

What to check

• Read the official scope language and compare the product’s physical characteristics, specifications, grade, dimensions, and end use; do not rely on the title alone.
• Confirm the country of origin and the manufacturer or exporter identified for the shipment, because AD/CVD coverage and duty treatment can depend on these facts.
• Check the applicable Harmonized Tariff Schedule (HTS) classifications, but treat them as an administrative aid rather than a substitute for the written scope.
• Review entry instructions, cash-deposit requirements, certification or documentation rules, and any scope rulings or customs guidance that may apply.
• Ask a customs broker or trade-remedy specialist to review borderline products, production changes, transshipment concerns, or uncertainty about scope and liability.
