Import Tips
• Supplier invoices must specify 'silk waste' type (hard/soft); ambiguity leads to 5004 audits
• Test for fugitive dyes per note (a)(ii); simple soap wash confirmation avoids colored yarn disputes
• Declare exact yarn metrics (twist, count) for statistical reporting; underreporting risks penalties
