Import Tips

• Provide slurry compatibility test data (e.g

• for silica or alumina) to support semiconductor end-use claims

• Label with maximum pressure and temperature ratings to comply with ASME B16 standards for customs

• Avoid reclassification by specifying 'diaphragm type' distinctly from ball or gate in entry docs
