Molds and Die Sets: Statutory & Effective Tariff Rates
USITC Column 1 General rates for 12 molds and die sets HTS lines (parseable range 0%–3.8%). Effective rate Jun 2026: 13.22%; monthly history since 2014.
The short answer
- The observed effective calculated-duty rate on U.S. imports of molds and die sets was 13.22% in Jun 2026, down from 13.3% a year earlier — USITC Calculated Duties divided by covered customs value. The Column 1 General line-rate range is 0%–3.8% across 12 HTS lines in the 2026 schedule; individual lines are called “Free” only when the official General field is literally Free, which still does not determine a shipment’s final duty. Canada is the largest source, holding 37.2% of 2025 imports.
Statutory rates from the schedule
- Injection molds, die-casting dies, compression molds, and die sets — the tooling behind every molded and stamped part. This family covers HTS heading 8480: 12 eight-digit rate lines with a parseable Column 1 General range of 0%–3.8% in the 2026 schedule. “Free” means the official General field is literally Free for that line; it does not determine final entry liability.
Observed calculated-duty data
- Latest month on record (2026-06): 13.22% effective on $175.9M of imports, versus 13.3% in the same month a year earlier. The monthly archive holds 150 observations from 2014-01 through 2026-06.
- In 2025, U.S. imports for consumption in this family totaled $2.3B in customs value, with $321.0M in USITC reported calculated duty on $2.3B of covered customs value: an effective calculated-duty rate of 14.1%. The aggregate reflects the recorded entry mix but does not attribute the result to a specific legal provision.
- A year earlier the effective calculated-duty rate was 4.97%, so the observed rate rose 9.1 points.

- Reported freight and insurance equaled 3.49% of covered customs value in 2025 ($68.2M total); charge coverage was 85.8% of customs value, from USITC DataWeb. It is shown alongside the effective calculated-duty rate and is not part of the customs-value duty base.
- Customs unit value: 69.7364 per unit in 2025, aggregate declared customs value divided by reported quantity across eligible single-unit lines (USITC DataWeb); not a transaction price.

Frequently asked questions
- What is the U.S. tariff rate on molds and die sets? USITC calculated duties imply an effective rate of 13.22% in Jun 2026 (calculated duties ÷ covered customs value, USITC DataWeb). The parseable Column 1 General line-rate range is 0%–3.8%; individual lines are called “Free” only when the official General field is literally Free, and product, origin, preference and tariff mix can contribute to the observed-rate difference.

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.
