常见问题
HTS 7304.22.00 的美国进口关税税率是多少？
HTS 7304.22.00（Tubes, pipes and hollow profiles, seamless, of iron (other than cast iron) or steel: — Casing, tubing and drill pipe, of a kind used in drilling for oil or gas: — Drill pipe of stainless steel）的美国进口基础税率（MFN general）为 Free；中国原产货件另叠加 Section 232 钢铁制品（50%）、全球 301 计划（CN，豁免）。示例口径（中国原产 · $10,000 · 海运正式报关）关税 + 规费合计约 $5,047.14。数据截至 2026-10-07（快照 v0.3.4）。
这个编码还要交 MPF/HMF 规费吗？
要。规费不是关税，按每票报关收取：港口维护费（HMF） 0.125%；商品处理费（MPF） 0.3464%（每票报关一次，min $34.58 / max $670.86）。示例口径（$10,000 正式报关）合计约 $47.14；货值 ≤$2,500 的邮递渠道走非正式报关固定规费。
HTS 7304.22.00 与 HS 编码、Schedule B 有什么区别？
三套编码同源不同用：HS 是世界海关组织的 6 位国际基准，HTS 是美国进口用的 10 位细码（前 6 位与 HS 一致，本页的 7304.22.00 即 HTS 8 位粒度），Schedule B 是美国出口统计编码（前 6 位与 HTS 相同，8–10 位后缀按普查口径另编）。进口美国报关税用本页 HTS 码，美国出口报关用 Schedule B。详见指南：/zh/guides/hts-vs-hs-vs-schedule-b
