Corrosion Inhibitors — China — C-570-123

“Corrosion Inhibitors” is the subject description for a U.S. trade-remedy measure involving products intended to slow or prevent corrosion. The description alone is not enough to decide whether a shipment is covered. Coverage is determined by the measure’s legal product scope, including the detailed physical characteristics, chemical composition, uses, and any listed exclusions.

AD/CVD means antidumping and countervailing duties. An antidumping (AD) measure addresses sales to the United States at less than fair value, while a countervailing duty (CVD) measure addresses certain foreign-government subsidies. These duties may apply in addition to ordinary customs duties and can affect importers, manufacturers, distributors, and related parties. The importer of record is generally responsible for entry accuracy and payment, and may face additional liability if Customs and Border Protection later determines that the merchandise was covered.

What to check

• Read the measure’s full scope language, not just the title, and compare it with the product’s ingredients, form, packaging, and intended use.
• Check the applicable HTS classification, but do not treat the tariff number as conclusive; AD/CVD scope language controls coverage.
• Identify the exporting country, producing company, and exporter, because AD/CVD treatment can depend on the country of origin and company-specific instructions.
• Review exclusions, certification requirements, and any special entry or deposit instructions in the official government sources before shipment.
• Ask a qualified customs broker or trade-remedy attorney to evaluate borderline products and document the classification and scope analysis.
