Material Composition Assumptions

A standard box of 100 paper clips weighs approximately 5 grams total. The primary component consists of galvanized steel wire comprising over 95% of the material mass at roughly 4.8 grams. A thin zinc coating applied during the galvanization process accounts for less than 5% of the total weight at approximately 0.2 grams. Some specialty variants include optional PVC plastic coatings that can add minimal additional weight when present.

Manufacturing Geography

China serves as the dominant manufacturing region for paper clips due to its extensive steel production infrastructure and wire processing capabilities. The Chinese national electrical grid operates at an intensity of 555 grams of CO2 per kilowatt-hour, reflecting the country’s continued reliance on coal-fired power generation. This manufacturing concentration results from established supply chains connecting steel mills directly to wire drawing facilities and forming equipment within industrial clusters.

Provenance Override Guidance

  1. Steel production method documentation specifying blast furnace versus electric arc furnace manufacturing processes used for the wire material.
  2. Galvanization facility energy consumption records showing actual electricity usage and renewable energy percentages during zinc coating application.
  3. Transportation distance and mode documentation covering shipment from steel mill to wire processing facility and final assembly location.
  4. End-of-life recycling program participation rates demonstrating actual material recovery percentages in target markets.
  5. Wire drawing and forming machinery efficiency specifications including energy consumption per kilogram of finished product manufactured.
