Importing Scientific Instruments from China into the United States in 2026 carries a total effective tariff of 39.0% (MFN 1.5% + Section 301 25%). That figure is the stacked rate applied to the customs value before fees. Use the calculator below for the exact landed cost, including Merchandise Processing and Harbor Maintenance fees.

How the Tariff Rate is Calculated
The tariff structure for scientific instruments follows the US stacking formula: the MFN base rate of 1.5%, plus Section 301 duty of 25%, plus forced-labor Section 301 duty of 12.5% (effective July 24, 2026, backfilling the lapsed Section 122 surcharge). The special tariff layer (the highest of Section 122, Section 232, or bilateral rates) is 0%, which combines with the MFN base to produce a subtotal before Section 301 duties. Adding all layers yields a total tariff rate of 39%. On a customs value of $10,600.00, this translates to total duties of $4,134.00, plus the Merchandise Processing Fee of $36.72 and Harbor Maintenance Fee of $13.25. The total landed cost including all fees reaches $14,783.97.
Trade Context
The United States imported $427B in goods from China in 2024, making it a significant trading partner in the Asia-Pacific region. Key import categories from China include consumer electronics, computers servers, clothing garments, reflecting the country's industrial and agricultural strengths. Scientific Instruments represents an important segment of this trade relationship, with demand driven by both price competitiveness and product availability in the US market. The bilateral trade volume underscores the economic significance of tariff policy decisions affecting imports from China.
What Section 122's Lapse Means for This Import
Section 122 lapsed on July 24, 2026 when its 150-day statutory limit expired — but the landed cost on scientific instruments from China did not fall to zero. A forced-labor Section 301 duty of 12.5% took effect at 12:01 a.m. eastern time the same day, backfilling the lapsed surcharge, so the total effective rate is 39%. Importers should treat the forced-labor duty — not the expired Section 122 surcharge — as the operative layer for scientific instruments.
Alternative Sourcing Countries for Scientific Instruments
Importers looking for lower tariff costs on scientific instruments may consider sourcing from Vietnam (effective rate 32.5%, saving approximately 6.5 percentage points); India (effective rate 28%, saving approximately 11.0 percentage points); Taiwan (effective rate 25%, saving approximately 14.0 percentage points). Compared to China's total effective rate of 39%, these alternatives offer potential cost savings depending on the specific product classification and applicable trade agreements. Each alternative carries its own tariff structure, so importers should calculate the full landed cost before switching suppliers.

Yes, Section 122 adds 0% to the tariff on Scientific Instruments from China. This surcharge was enacted on February 24, 2026 under Section 122 of the Trade Act and applies uniformly to imports from most countries. It stacks on top of the MFN base rate of 1.5%, contributing to the total rate of 39%.
Section 122 lapsed on July 24, 2026 when its 150-day statutory limit expired without renewal — but the landed cost on Scientific Instruments from China did not fall to zero. A forced-labor Section 301 duty of 12.5% took effect at 12:01 a.m. eastern time the same day, backfilling the lapsed surcharge. The total tariff rate is 39%; importers should treat the forced-labor duty — not the expired Section 122 surcharge — as the operative layer.
For Scientific Instruments, alternative sourcing countries to consider instead of China include Vietnam (effective rate: 32.5%), India (effective rate: 28%), Taiwan (effective rate: 25%). Compared to China's total effective rate of 39%, these alternatives may offer lower landed costs depending on the specific HTS classification.
