Seven years of fuse imports
Imports of fuses over 1,000 V grew from $142.1 million in 2019 to $204.4 million in 2025, a rise of 43.8%. Low-voltage fuses (1,000 V or less, HS 8536.10) are a larger trade: $374.3 million in 2025, with Mexico at 66.3% and China at 8.9%.
| Year | Fuses over 1,000 V | Mexico share | China share | Duty, over 1,000 V | Fuses up to 1,000 V | Duty, up to 1,000 V |

Did tariffs change what fuses cost?
Duties rose sharply in 2025. The duties the Census Bureau calculated on imported fuses over 1,000 V came to $15.5 million in 2025, against $6.5 million in 2024: 7.6% of the goods' value, up from 3.2% (and 2.4% in 2019). On fuses from China the figure went from 27.4% to 56.3%. On fuses from Mexico it was 2.3% in 2025. For January to September 2026 it stands at 5.6%.
The values in this study are customs values, which leave out duty, freight and insurance, so they show what the goods were declared at before any tariff was added. The average declared value of a fuse rated 2,300 V or more (HTS 8535.10.0020) rose from $14.32 in 2019 to $22.79 in 2025, a rise of 59%. Part of that is a change in which fuses were imported rather than a change in price, and the data cannot separate the two.
| Year | Imports | Fuses imported | Average value per fuse |
|---|---|---|---|
| 2019 | $118.7 million | 8.3 million | $14.32 |
| 2020 | $105.0 million | 7.3 million | $14.31 |
| 2021 | $96.2 million | 6.8 million | $14.10 |
| 2022 | $125.5 million | 7.6 million | $16.58 |
| 2023 | $136.5 million | 8.1 million | $16.91 |
| 2024 | $153.6 million | 7.9 million | $19.51 |
| 2025 | $156.5 million | 6.9 million | $22.79 |
2026 so far
From January to September 2026 the United States imported $203.2 million of fuses over 1,000 V, 35.5% more than the $150.0 million in the same months of 2025. Mexico's share was 69.7%. Imports from Canada went from $1.1 million to $15.8 million, 7.8% of the total.
What this means for utility and industrial fuse buyers
- Imported supply is concentrated. Mexico and the Dominican Republic shipped 79.4% of the fuses over 1,000 V that entered the country in 2025, so it is worth knowing where each fuse on your approved list is made.
- Duty now varies a lot by origin. With duty on Chinese-made fuses at 56.3% of their value in 2025, ask suppliers to state the country of origin and whether duty is included when they quote.
- Older price assumptions may be out of date. The average declared value of a fuse rated 2,300 V or more was $22.79 in 2025 against $14.32 in 2019, before any duty, so budgets built on older quotes are worth checking against a current one.
- Sourcing can shift within a year. Imports from Canada were $1.1 million in January to September 2025 and $15.8 million in the same months of 2026, so check the origin on repeat orders as well as new ones.
Method
We downloaded US import records from the Census Bureau's international trade API for two Harmonized System codes: 8535.10, fuses for a voltage exceeding 1,000 V, and 8536.10, fuses for a voltage not exceeding 1,000 V. For each full year from 2019 to 2025, and for January to September of 2025 and 2026, we took general imports at customs value by country of origin and computed each country's share of the total. Duty figures use the Census calculated duty divided by imports for consumption. Fuse counts and values per fuse come from the 10-digit HTS lines under 8535.10, where Census reports the number of fuses. The scripts and raw files are kept with the site's source so every figure can be rebuilt. Data fetched 12 Nov 2026.
Sources
- US Census Bureau, International Trade API: imports by HS commodity. Period used: January 2019 to September 2026.
Limits
- Trade data count fuses crossing the border. They do not measure US production, so they cannot say what share of US demand is met by imports.
- Country of origin is where a fuse was made or last substantially transformed, not where it was shipped from.
- HS 8535.10 covers every kind of fuse over 1,000 V, from small links to large current-limiting fuses, so the average value per fuse mixes very different products.
- Calculated duty is the Census Bureau's estimate from tariff rates, not the duty actually collected, and it applies to imports for consumption only.
- Monthly figures for 2026 are preliminary and may be revised. Census publishes revisions each year.
