Import Tips
• Include lab certifications for tar saturation levels below coating thresholds to stay in 4805; overstating impregnation can lead to 4811 reclassification
• Declare exact basis weight and burst strength in entry docs, as roofing felts often scrutinized for construction material duties
• Avoid shipping in pre-cut sheets with perforations, which could fall under chapter note exclusions for heading 4820
