Import Tips
• Label shipments clearly with 'refractory clay bricks' and dimensions to match statistical reporting suffixes
• Obtain manufacturer's declaration of pyrometric cone equivalent (PCE) >27 to substantiate refractory clay classification
• Watch for misdeclaration as building bricks (6904.10); refractory use requires proof of high-temperature application
