The implementing Federal Register notice reduced the tariff rate for HTS 9903.04.63, covering patented pharmaceutical articles that are products of the United Kingdom, from 10% to 0%.

A Type 232 measure refers to action under Section 232 of the U.S. Trade Expansion Act of 1962. It addresses imports that the U.S. government has determined may affect national security. The measure may apply to particular products, materials, or derivatives, and the requirements can depend on the product’s tariff classification, country of origin, and applicable exclusions or exceptions.

For an importer, this can mean an additional tariff, a quota, special entry instructions, or another import condition beyond the ordinary customs duty. The key professional terms to understand are HTSUS classification (the product’s tariff code), country of origin, scope (which goods are covered), and exclusions or quota provisions. Coverage is determined from the official measure text and customs guidance—not from a product description alone.

What to check

• Confirm the product’s complete HTSUS classification, including any relevant statistical suffix, with supporting product details.
• Read the measure’s scope carefully to determine whether the exact product, material, and form are covered; do not rely only on a title or database label.
• Verify the product’s country of origin under U.S. customs origin rules, which may differ from the shipping or export country.
• Check official CBP instructions and the current HTSUS for any additional duty, quota, reporting, entry, or product-specific requirements.
• Review whether an exclusion, exception, quota treatment, or other special provision applies, and obtain customs-broker or trade-counsel advice when classification or coverage is uncertain.
