Shipping Weight Calculator
Compare actual and volumetric weight with a divisor you enter. Planning comparison only—not a carrier invoice.
Open tool →Tools
Superbuy Spreadsheet Tools
Browser-side planners and lookups you control. No live Superbuy fee APIs and no invented quotes.
Use these utilities when you already have measurements, cost lines, warehouse photos, or an ID/link to check. Outputs stay planning aids: weight comparisons, CNY totals, checklist coverage, and snapshot matches.
Total Cost Calculator
Add product, domestic, handling, and international CNY estimates, then view approximate USD with an editable planning divisor.
Open tool →QC Checklist Tool
Tick visible warehouse-photo checks by item type and track checklist coverage—not a quality or authenticity score.
Open tool →Product Link Preflight
Look up a Product ID, Weidian ID, or Weidian product link in this catalog snapshot. Local match only—not live stock.

Tools questions
Are these official Superbuy calculators?
No. They are independent browser planners on this research site. Official checkout math and line quotes stay in Superbuy or carrier tools you use separately.
Do the tools use live Superbuy APIs?
No. Weight, cost, and checklist tools only use values you type. Preflight matches against the local catalog snapshot—not a live Superbuy inventory API.
Are entered values sent to a server?
No. Calculations and checklist ticks run in your browser. Closing the tab discards ephemeral inputs unless your browser itself restores form state.
Which tool should I open for weight, cost, QC, or ID lookup?
Use Shipping Weight Calculator for actual vs volumetric comparison, Total Cost Calculator for CNY line sums, QC Checklist for visible photo coverage, and Product Link Preflight for Product/Weidian ID or supported Weidian URL matches in the snapshot.
