Specifying Amounts of Materials, Trims, and Packaging

Specifying Amounts of Materials, Trims, and Packaging

After selecting the materials, trims, and packaging for the Bill of Materials, the amounts of all components need to be added. It is important to note that it should be the gross amount that is specified (the amount needed to make the product) and not the net amount (the amount that ultimately ends up included in the final product).

Products that come in a range of sizes but have a single Bill of Materials (where the difference in gross amount between the sizes is accounted for in pattern grading and size curves) are not required to break out each size separately and can share the same product assessment. If products have separate Bills of Materials, then they should be set up as separate product assessments.

The default unit for specifying amounts of materials is kilograms. This unit can be changed to other mass units (grams, milligrams, pounds, ounces). When using Custom Materials that have been created with customized Units of Measure and Yield Conversions, additional units of measure can be selected (such as yards, square feet, and cubic inches).

The default unit for trims and packaging is “units.” This means that the unit of measure is built into the Trim or Packaging option itself. For instance, for a product like a button, a unit would be a piece (i.e., a single button). For shoelaces, a unit could represent a pair of laces. For zipper tape, a unit could represent one linear centimeter. It is important to specify the unit type quantifying theTrim or Packaging. An easy way to ensure recognition for all users is to add the unit type into the Trim or Packaging name. For instance, “Zipper Tape (per cm)” or “Shoelace (pair).”

Examples (Specifying Amounts)

A garment requires 2 yards of fabric to accommodate the pattern pieces. Even though the end product doesn’t use all 2 yards (since there is cutting waste), the Bill of Materials should specify 2 yards, as that is the gross amount of material needed.

A pair of sneakers requires 250 grams of rubber to make the outsole. After trimming, the outsole only weighs 200 grams. The Bill of Materials should specify the gross amount of 250 grams of rubber.

A t-shirt comes in a range of sizes from extra-small to extra-large. Even though the final products have different weights, there is only one Bill of Materials that specifies 1.5 yards of material per t-shirt. Only one product assessment is needed for this product and the Bill of Materials should specify 1.5 yards of material.
