About this product
This catch-all heading covers foundry binders, additives and many other chemical preparations. A few lines are in an EU quota for starch derivatives, and most others are phased out within a few years. Mercosur phases out its duties over short and long schedules.
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.
Into the EU from Mercosur

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.

Tariff-rate quotas
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.
