Import Tips

• Submit OEM certification linking blades to steam turbine models used in semiconductor grinders

• Comply with dimensional tolerance declarations (e.g

• micron-level flatness specs) for classification support

• Avoid reclassification by separating from lapping/polishing consumables on import manifests
