CBP's answer: D. D: The trousers must have a water resistance such that, under a head pressure of 600 millimeters, not more than 1.0 gram of water penetrates after two minutes when tested in accordance with AATCC Test Method 35 and the water resistance must be as a result of a rubber or plastics application to the outer shell, lining, or inner lining.

Chapter 62 Additional U.S. Note 2 defines water resistant for subheading 6203.43.75: not more than 1.0 gram of water penetrates after two minutes at a 600 millimeter head pressure under AATCC Test Method 35, and the resistance must come from a rubber or plastics application to the outer shell, lining or inner lining. Only choice D has both parts. Choice B names the wrong test method (53) and C omits the plastics application.

This water resistance must be the result of a rubber or plastics application to the outer shell, lining or inner lining. Chapter 62, Additional U.S. Note 2
not more than 1.0 gram of water penetrates after two minutes when tested in accordance with the current version of AATCC Test Method 35 Chapter 62, Additional U.S. Note 2
