Import Tips & Compliance

β€’ Provide end-use statement linking to semiconductor processing to support cleanroom material claims

β€’ Sets must be pre-packaged; loose gaskets risk reclassification to 8484.10 or Chapter 39

β€’ Avoid delays by certifying particle-free packaging suitable for wafer fab environments
