About this product
Shafts, bearing housings, gears and clutches are mostly free in the EU from the start, with a few lines phased out within a few years. Mercosur's duties fall to zero over long schedules, with one line excluded. Car and machinery makers on both sides trade these parts.
How the duty falls, year by year
Highest and lowest ad valorem duty each year over the lines on a path to zero. Excluded and quota-only lines keep their duty and aren't included.

Lines by staging category
The staging category sets the speed of the cut: 0 is duty-free from entry into force, 4 to 15 are the years to zero, E is excluded and letter codes are quotas or special treatments.

Rates in each Mercosur country
Each member has its own base rate and applied MFN rate. The preference is cut from the base rate, or from the applied rate where that's lower (Art. 2.4(7) of the agreement), so the current rate can differ by country.

Data and method
Worked out with the calculator's engine from the agreement schedules (Annex 2-A) and the applied-rate files, for agreement year 2026. Mercosur → EU figures assume Brazilian origin, which only matters for the few origin-specific quotas; EU → Mercosur figures are for Brazil unless the country table says otherwise.
