This example illustrates how the list of ingredients of a tobacco product would be represented.
The unique tobacco product substances interest would be assigned a STRFID identifier in the (IL) Ingredient List domain. The SPTOBID identifier is included in this IL domain to identify the tobacco product to which these ingredient data pertain. INCAT is used to differentiate the different categories of ingredient. INSCAT may be used to further differentiates sub categorize these ingredients. INCAT/INSCAT categories would be detemined by the sponosr and typically depend on the type of tobacco product being described. STRFID indicates the Reference ID assigned to the substance/ingredient by the sponosr. Each ingredient/substance record must be unique. Hence, the mu In this example the FDA UNII number was used. This was used since not all ingredients have a CAS Number, but usually have have UNII numbers. The information on what dictionary/code list was associated with STRID is provided in the define.xml that is submitted with the data. For example,. The same Iingredient from different manufacturers would be listed on separate lines.
The IT example shows tobacco filler and the types of tobacco of which it is composed, each listed as tobacco ingredients in the variable IGDCMPID (ingredient or component identifier) for the tobacco product CIG01A (SPTOBID). The variable ITSPECIF shows the specification/variety of the first 3 tobaccos. ITIGDPLX (Ingredient Complexity) is used to indicate that the tobacco filler and the reconstituted tobacco are complex ingredients (i.e., have 2 or more subcomponents). The details of which single tobacco ingredients compose these complex ingredients is made explicit in the IQ dataset example. ITCURMTH indicates the cure method. ITCIGIND (applicant-customized ingredient indicator) is used to indicate whether complex ingredients were made to the applicant's specification. TPMF indicates the Tobacco Product Master File name/number, which should be provided in the data if the component manufacturer has made it available.
Note that there are 2 varieties of burley tobacco in this tobacco product; each is given a unique IGDCMPID value (Burley Tobacco and Burley Tobacco 2).

The IN dataset example shows the list of non-tobacco ingredients used in the tobacco product identified as CIG01A. Each unique ingredient is listed in IGDCMPID. Where applicable, IUPAC name and CAS number are listed (IUPACNAM and CASNO variables, respectively). INIGDPLX is used to indicate whether an ingredient is a single ingredient or a complex ingredient. INCIGIND indicates whether complex ingredients were made to the applicant's specification. Grade, purity, manufacturer name, ingredient unique item number, and the Tobacco Product Master File number complete the dataset.

This example represents the target and max and minimum quanity of each unique ingredients in each compoment of a tobacco product. STRFID must be represented using the identical value defined by the sponosr in the Ingredient (IL) domain. IQUNIT is the unot assoicated with the target, min, and max.
Finally, the IQ domain is used to represent the quantity (target, minimum, and maximum) of each ingredient identified in IGDCMPID that the product (SPTOBID) is designed to contain, with the units for these values represented in IQUNIT. The function of each ingredient is described in IQFUNCT. Note: Ingredients that appear in more than 1 component of the tobacco product are quantified separately for each component. IQPARENT identifies a component or complex ingredient composed of the subcomponents/ingredients shown in IDGCMPID. IQLEVEL is used to identify at what level in the overall hierarchy that subcomponent/ingredient appears.
The following implementation rules apply, as described in more detail in Section 2.8.8.6, SDTM Ingredient Quantities by Component (IQ), Assumptions:
- IQPARENT must correspond to a value of IGDCMPID in the same dataset. If parent is null, the ingredient is considered a top-level component and is assigned an IQLEVEL value of "1".
- Records describing subcomponents/ingredients that compose a parent component listed in the dataset will have IQPARENT value equal to the IGDCMPID of that parent component. IQLEVEL will be set to n +1, where n = the parent record's value of IQLEVEL
- Every value of IGDCMPID used in the IQ dataset must have a matching value of IGDCMPID:
- In the IT dataset (when IQCAT=TOBACCO INGREDIENT), or
- In the IN dataset (when IQCAT=NON-TOBACCO INGREDIENT)
Therefore, IQCAT is required to relate ingredient quantity records in IQ to the associated ingredient attributes described in either IT or IN.
The use of IQPARENT and IQLEVEL help make explicit the relationship between complex ingredients or components and the subcomponents/ingredients of which they are composed, and can assist when totaling the quantities of an ingredient that appears in multiple components of a tobacco product.
This concept map illustrates the representation of the hierarchical relationships between a component and its subcomponents/ingredients in the IQ domain structure.

The IQ dataset example illustrates these principles, using a cigarette tobacco product:
| Dataset wrap |

|
| Rowcaps |

| Rows 1, 13, 16: | Show 3 top-level components of a cigarette product: tobacco filler, filter, and cigarette paper, respectively. Their target, minimum, and maximum quantities expressed in units of mg/cigarette are shown in IQVALTRG, IQVALMIN, IQVALMAX and IQUNIT. Because there is no parent component other than the finished product itself, IQPARENT is null, and IQLEVEL=1, indicating that these are top-level ingredients/components of the finished product. | | Rows 2-5: | Show the quantities of 4 types of tobacco used in the product. IQPARENT=Tobacco Filler and IQLEVEL=2, together indicating that these are subcomponents/ingredients in the tobacco filler, a top level-component of the cigarette product. | | Rows 6-8: | Show the 3 tobacco ingredients that compose reconstituted tobacco in row 5 (IQPARENT=Reconstituted Tobacco). The quantities of these tobaccos pertain to the quantity at which they appear in the reconstituted tobacco ONLY. IQLEVEL=3 to show that these ingredients are at the third level of the hierarchy (subcomponents/ingredients in Reconstituted Tobacco, which has IQLEVEL=2). Therefore, the total quantity of the individual tobaccos used in this tobacco product is the sum of these 3 rows plus the sum of the quantities shown in rows 2-4. | | Rows 9-10: | Show the quantities of 2 non-tobacco ingredients, methylcellulose and 1,3-butanediol, which are further subcomponents/ingredients in Reconstituted Tobacco, as indicated by IQPARENT. IQFUNCT shows that methylcellulose functions as a binder and 1,3-butanediol functions as a humectant. IQLEVEL=3 to show that these ingredients are at the third level of the hierarchy. | | Rows 11-12: | Show the quantities of 2 subcomponents/ingredients that both function as a flavorant in the tobacco filler (as indicated by IQFUNCT= Flavor and IQPARENT=Tobacco Filler). | | Rows 14-15: | Show the quantities of 2 subcomponents/ingredients that function as filtration and plasticizer, respectively, in the filter portion of the cigarette (cellulose filter A, a top-level component shown in row 13). | | Rows 17-22: | Show the quantities and functions of 6 subcomponents/ingredients in the top-level component FSC paper B (the cigarette paper shown in row 16). |
