Import Tips & Compliance

Verify dimensions do not exceed 3mm diameter or 25mm length to qualify under this subheading; larger sizes shift to 6914.90.50

Provide material test reports confirming alumina/zirconia composition and firing process per Chapter 69 notes

Ensure documentation specifies single-mode or multimode fiber channel specs to avoid misclassification as general ceramic parts
