Import Tips

Include end-use certification if destined for zippers to support valuation but maintain wire classification under 7217

Document exact tin coating weight/thickness to distinguish from Chapter 73 finished zipper products

Ensure wire remains in coils/bundles, not formed into shapes, to avoid classification as parts of machines (84/85 chapters)
