What label color should be attached to the exterior of each package, per PPQ Form 550?

• A. Black/White
• B. Red/Blue
• C. Green/White
• D. Yellow/Black

Answer: (A)

High-contrast exterior labeling is essential for shipments governed by PPQ Form 550 because it ensures quick readability and proper handling during inspection and transport. Using black on white creates the strongest contrast, making the label easy to read from a distance, in various lighting conditions, and even if the package is moved or partially obscured. This readability supports accurate identification by inspectors and reduces the chance of misinterpretation, delays, or misrouting. The choice also aligns with common labeling practice where simple, high-contrast colors minimize confusion across different facilities and systems. Other color combinations tend to be harder to read or may imply different meanings in other contexts, so the black/white pairing is chosen to provide clear, universal visibility for these regulated shipments.
