Each row below represents one owner per step. Inputs and outputs reference live filenames used in the compliance archive. All torque, SOC and voltage limits are taken from the Bussmann gPV 1000V DC datasheet (rev. 2024-03): rated voltage 1000 V DC; rated current 15 A, 20 A, 25 A, 30 A; interrupting rating 50 kA at 1000 V DC; tightening torque 2.5 N·m (22 in-lb) on M5 stud. Fuses are passive components — no SOC state applies; verification is static marking audit on the fuse element.

DC fuses (Bussmann gPV 1000V DC supplemental fuse family, BSPM_LPFR series) typically fall under Harmonized Tariff Schedule heading 8536 — "Electrical apparatus for switching or protecting electrical circuits, or for making-up and protecting connections to or in electrical circuits" — per the USITC HTS chapter 85 heading 8536 wording. The exact 10-digit statistical breakout, applicable MFN duty rate and any Section 301 actions must be confirmed live by a licensed customs broker using the USITC HTS search portal. CBP requires re-verification at time of entry per 19 CFR Part 163.

Disclaimer. TradVolt publishes process guides for informational purposes. Nothing on this page constitutes legal customs, certification or financial advice. HS classifications, duty rates, Section 301 status and OEM datasheet values change; re-verify through the named regulator and cert body portals before any commercial action. Pricing slots labelled indicative / UNCERTAIN / PENDING are not quotations. Equipment scope is limited to the Bussmann gPV 1000V DC supplemental fuse family (BSPM_LPFR series, rev. 2024-03) — other DC fuse models require their own OEM datasheet and UL file cross-check.
