Importyeti Supplier Analysis Amazon

ImportYeti is one of the most accessible tools for querying US Customs Bill of Lading data. For Amazon seller supply chain research, it provides the primary route to competitor factory identification, replenishment cadence mapping, and supplier overlap analysis. This is how to use it effectively and what to look for.

Why this matters

US Customs BOL data is public record under the Freedom of Information Act, but the raw data is not easily searchable. ImportYeti indexes and normalizes that data into a searchable format: query a brand name, see their shipper factories and container arrival history. For an Amazon seller doing competitive supply chain research, this is the fastest path to answering 'where does my competitor source from, and how often?'

The research value of ImportYeti increases with the specificity of the query. A broad brand name search returns all imports under that entity name. A targeted search — specific importer name, date range, shipper name — returns the exact records needed to calculate cadence, identify factory changes, or map supplier overlap across the category.

How to structure an ImportYeti query

Start with the brand's US legal entity name — not the Amazon storefront name, which may differ. If the legal entity is unknown, try the brand name, the Amazon seller name, and any parent company name. ImportYeti searches the 'Consignee' field of BOL records, which is the US importer of record.

Extracting replenishment cadence from the arrival history

From the arrival history, sort by arrival date. Calculate the gap between successive arrivals. List the gaps in chronological order. Average the gaps over 12 months for the baseline cadence. Look at the most recent gap: is it shorter than average (ahead of cadence), at average (on cadence), or longer than average (behind cadence)?

Identifying shipper factories and factory changes

Each BOL record includes a 'Shipper' field: the factory or trading company exporting the goods. For a brand's import history, the shipper names across multiple arrivals reveal: which factory they use (consistent shipper name), whether they use multiple factories (multiple shipper names), and whether they have changed factories (a new shipper name appearing in recent months).

Building a category supplier map

Repeat the ImportYeti query for each of the top 10-15 category sellers. For each brand, record: shipper name, shipper country, arrival dates. Build a matrix: brands on one axis, shipper factories on the other. Mark which brands use which factories. Factories that appear across multiple brands are the category's concentration nodes. This is the supplier overlap map — the most direct view of the category's supply chain structure.

Decision rule: An ImportYeti supplier analysis is complete when: the correct US importer entity is confirmed for each competitor queried; at least 12 months of arrivals are reviewed per brand; cadence is calculated for each competitor; shipper factories are identified and factory changes are noted; and the category supplier matrix is built across the top 10+ sellers. A supplier analysis built on fewer than 10 seller queries may miss the factory concentration nodes that define the category's structural risk.

ImportYeti supplier analysis checklist

Competitor's US legal entity name confirmed before querying — check brand name, Amazon seller name, and parent company variants
Full arrival history exported for date-range analysis: at least 12 months of BOL records
Arrival dates sorted chronologically and inter-arrival intervals calculated
12-month baseline cadence calculated and most recent interval compared to baseline
Shipper factory names extracted for each arrival: consistent factory, multiple factories, or recent factory change?
Factory change identified: has a new shipper name appeared in the last 12-24 months?
Category supplier matrix built: top 10 sellers mapped to their shipper factories
Concentration nodes identified: factories that supply 3+ category sellers

Common mistakes

Querying by Amazon storefront name when the US importer entity is a holding company or DBA with a different name. Treating the shipper name as a factory name without verifying — many shippers are trading companies representing multiple factories. Reading the most recent arrival date as the current inventory date without accounting for the 4-8 week data lag.
