Forced-labor Section 301 — Oman — 12.5% additional duty

A Section 301 measure is a U.S. trade action that can impose an additional duty on covered merchandise because of specified trade practices or policy concerns. A measure described as involving forced labor and Oman generally signals that the product’s country of origin, tariff classification, and connection to the named country must be examined—not simply where the seller or online marketplace is located.

This type of measure typically affects importers of products that fall within listed Harmonized Tariff Schedule (HTSUS) classifications and meet the measure’s stated country and scope conditions. The additional duty is generally separate from the product’s ordinary customs duty and may apply in addition to other applicable trade measures. The importer of record is responsible for entry accuracy, including classification, origin, valuation, and reporting any required additional-duty provision.

What to check

• Confirm the product’s HTSUS classification using the complete tariff description, not only a commercial product name or a partial tariff number.
• Determine the product’s customs country of origin under U.S. origin rules; do not assume origin from the shipping location, seller, or last warehouse.
• Read the measure’s exact scope and exclusions, including any product specifications, processing conditions, or qualifying exceptions.
• Check the official tariff instructions and entry-filing guidance for the correct additional-duty reporting provision and any required documentation.
• Keep records supporting classification, origin, supply-chain details, and eligibility for an exclusion; ask a customs broker or trade counsel when the facts are uncertain.
