What tariff does the U.S. charge on carbon products and insulators from Mexico?

In 2025, USITC reported an effective calculated-duty rate of 3.2% for carbon products and insulators imported from Mexico, calculated as reported Calculated Duties divided by covered customs value. It reflects the observed entry mix but does not identify the legal cause of the rate or determine an entry-specific duty.

How much carbon products and insulators does the U.S. import from Mexico?

The U.S. imported $167.7M of carbon products and insulators from Mexico in 2025, 13.3% of the tracked carbon products and insulators it imports, ranking Mexico the 2nd-largest named source. The chart above traces the retained reported years; a year with no retained source row is unknown, not zero.

What does freight add on carbon products and insulators from Mexico?

Cost, insurance, and freight ran 0.95% of customs value on carbon products and insulators from Mexico in 2025. That is an additional import burden alongside the reported effective calculated-duty rate; a country-specific invoice price is still required for a comparable landed unit cost.

About this data

Reference statistics derived from USITC published data. Not a customs ruling. MFN-Free and Special-rate fields describe statutory line coverage only; final entry liability requires origin, date, eligibility, exclusions and other transaction facts. Calculated Duties are statistical estimates, not a cash-collections ledger. Confirm classification, origin, program eligibility, and final entry liability with a licensed customs broker.
