About this product

Seamless tubes and pipes, used heavily in oil and gas, already enter the EU duty-free. Mercosur phases out its duties on European tubes over long schedules. The oil and gas sector is the main buyer.

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.

Tariff-rate quotas

No tariff-rate quota applies to this heading.

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.

Methodology and data sources

Estimates only, not legal or customs advice. Check the official schedules before relying on a rate.
