常见问题
HTS 7318.15.00 的美国进口关税税率是多少？
HTS 7318.15.00（钢铁制螺丝/螺栓）的美国进口基础税率（MFN general）为 9% + 0.5¢/kg（示意数据）；按当前规则快照，该编码未命中对华 301 / 232 叠加层。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：MPF 为申报值的 0.3464%（FY2027 每票 $34.58–$670.86），海运另加 HMF 0.125%；货值 ≤$2,500 的邮递渠道走非正式报关固定规费。
HTS 7318.15.00 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 7318.15.00 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
