A customs duty is a tax levied at the border on imported goods. There are different technical methods of assessing customs duties - ad valorem (percentage of import value), specific (based on weight or volume of goods), mixed (ad valorem or specific - whichever is higher/lower), compound (ad valorem and specific) or on another basis (e.g. according to percentage content of a product component). In the IDB, the duty nature code is used to record the technical method of duty assessment. Examples of different methods of duty assessment are as follows:
AD VALOREM DUTY (Duty nature code = A)
An ad valorem duty is expressed as a percentage of the value of the imported goods (e.g. 10% of value).
SPECIFIC DUTY (Duty nature code = S)
A specific duty is not related to the value of the imported goods but to the weight, volume, surface, etc. of the goods. The specific duty stipulates how many units of currency are to be levied per unit of quantity (e.g. 2.00 Swiss Francs per KG). In the case of specific duties, the ad valorem equivalent (AVE) can be calculated, which gives the equivalent level of the duty in percentage terms at a given time (the year of imports used in the calculation).
COMPOUND DUTY (Duty nature code = C)
A compound duty comprises an ad valorem duty to which is added or subtracted a specific duty: 10% plus $2.00/KG; 20% less $2.00/KG.
MIXED DUTY (Duty nature code = M)
A mixed duty ensures a minimum or a maximum tariff protection by the choice between, in general, an ad valorem duty and a specific duty as in the following examples: 10% minimum $2.00/KG; 10% or $2.00/KG whichever is less; 10% maximum $2.00/KG, etc.
OTHER DUTY (Duty nature code = O)
Examples of other duties are: $0.51¢ each + 6.25% on the case and strap, band or bracelet + 5.3% on the battery; 3.1¢/liter + 22.1¢/pf. liter on ethyl alcohol content
Duties are stored in the IDB Tariff Coded (TC) file. The duty type (pos.1 below) / duty code (pos.2-3 below) fields are used to distinguish the different types of duties as follows:
01 = MFN Current Bound duty
For each tariff line on which a concession has been offered, this is the bound duty in force for the year of the tariff. Depending on the year and the staging period for implementation of the concession, the current bound duty contains either the staged reduction for the year of the tariff or the final bound duty.
02 = MFN Applied (legal/statutory/autonomous) duty
Also known as "Statutory", "legal" or "autonomous" duties, these are the legal customs duties, which are normally published in the customs tariff law voted by Parliament. Usually this duty applies when the tariff line is unbound or, if the tariff line is bound, when it is lower than the MFN current bound duty.
03 = MFN Effectively applied (temporary) duty
Also known as "temporary" duty, these customs duties are applied for an undetermined period of time or for a limited period of time. Temporary duties are sometimes voted by Parliament or, more often, decided upon by the government for economic reasons (inflation, balance of payments, etc).
09B = MFN Uruguay Round base duty
The duties that were used as a basis for the Uruguay Round of trade negotiations, i.e. MFN bound duties as of 1988 and, for unbound items, MFN applied duties applicable as of September 1986.
09F = MFN Uruguay Round (or more recent concession) final bound duty
The duties offered as concessions for the Uruguay Round of or more recent concessions. Where applicable, this is the bound duty in force at the end of the staging period. If the end of the staging period has been reached, this duty would be equal to the MFN current bound duty.
10-19 = Free Trade Area duty
Duties applicable to signatories of Free Trade Agreements. For a given Member, a different duty type/code is used for each agreement to which the Member is signatory.
20-29 = Zone-Zone duty
Duties applicable to signatories of preferential agreements between trade zones, such as EFTA and the EU.
30-39 = Other preferential duty
Usually bilateral preferences, which are not necessarily granted on a reciprocal basis. For a given Member, a different duty type/code is used for each country to which preferences are granted.
40-49 = GSP duty
Duty type/code 40 is used to record preferences offered unilaterally by developed and transition Members under the Generalized System of Preferences (GSP). Exceptions to the GSP Scheme can be recorded using duty type/codes 41-49. Duty type 40 is also used to record preferences offered under the Global System of Trade Preferences among Developing Countries (GSTP).
50-59 = LDC duty
Duty type/code 50 is used to record preferences offered to Least Developed Countries.
80 = General duty (higher than MFN)
Duty applicable under general treatment. These duties, which are less favourable than MFN, are applied to non-WTO Members in some import markets.
Of the above duties, provision of the MFN current bound duty and the MFN current applied duty is mandatory under the IDB notification requirement. Provision of the other types of duties is optional.
If the tariff line is bound, the MFN applied duty can be lower than or equal to the MFN current bound duty, but it cannot be higher. The MFN effectively applied (temporary) duty can be lower or higher than the MFN applied duty but, if the tariff line is bound, it cannot be higher than the MFN current bound duty. The MFN current bound duty or the MFN applied duty (if the duty is unbound) should be present for every customs tariff line in the IDB.
When preferential duties are supplied, the IDB can contain all duties applicable under FTA agreements, regional agreements (zone-zone duties), other preferential arrangements (usually bilateral) and under the GSP or GSTP schemes. If a country grants a differentiated tariff treatment to least developed countries (LDCs), the duty applicable to LDCs can also be recorded. The IDB format provides a means to associate to each duty, the country or the group of countries to which the duty applies. It is also possible to record trading partner exclusions to preferential arrangements at the tariff line level.
Duties applicable under general treatment can also be recorded. These duties, which are less favourable than MFN, are applied to non-WTO Members in some import markets.
Anti-dumping and countervailing duties (compensatory duties applied under Article VI of the GATT 1994), duties relating to safeguard measures, duties relating to the dispute settlement process and excise duties are not covered in the IDB.

Note: Non-Secretariat sources sometimes use the term "tariff" to refer to a duty. For the IDB, the Secretariat usually uses the term "tariff" when referring to the whole of a customs tariff. The Secretariat usually uses the term "duty" rather than "rate" unless specifically referring to an ad valorem duty rate.
ALTERNATIVE SPECIFIC TARIFF (referred to as a mixed duty in the IDB) - A tariff rate set either at an ad valorem rate, i.e. expressed as a percentage of the value of the product, or at a specific rate, i.e. set as a fixed monetary rate per article. The customs authorities then usually apply the higher of the two. See also ad valorem tariff and specific tariff.

EXPORT TARIFFS - A levy on goods or commodities at the time they leave a customs territory. Reasons for imposing export tariffs include raising revenue, the desire to promote further processing of commodities within the country and a policy of ensuring that commodities perceived as scarce and necessary for domestic production are reserved as much as possible for local industry.

TARIFF-RATE QUOTA - A quota that is determined on the basis of the applicable tariff rate applied to imports. A predetermined amount of a good is allowed to enter at a reduced or zero tariff rate. After the quota has been filled, all subsequent shipments of that good during a specific period of time, such as a calendar year, are assessed a higher import tariff, usually the normal most-favored-nation tariff.

IN-QUOTA RATE - The tariff applicable to a product imported within the limits of a tariff quota.

OUT-OF-QUOTA RATE - the tariff rate applicable to products imported in excess of a tariff quota. This rate is meant to discourage imports above the quota limit. It is usually much higher than the one applied to imports within the quota.
