Silicone Rubber Calendering Machine from China

This machine calenders uncured silicone rubber sheets to precise thickness for use in semiconductor cleanroom gaskets and seals. It falls under HTS 8420.10.9080 as a calendering machine for non-metallic, non-glass materials like rubber essential in semiconductor processing environments. The heated rollers ensure uniform calendering without contamination.

Import Tips

Verify machine specifications confirm non-metal/glass use; provide end-use certification for semiconductor applications to avoid reclassification

Ensure rollers meet cylinder specs in invoice descriptions

Watch for misclassification as plastic machinery
