Illustrative composite from the previous 4-weekly shortlists — actual decay curves are surfaced per SKU.

What the shortlist actually carries

Not another bestseller index. A defensible roster.

I.

Where universal demand still rewards a specialist

We narrow the week to durable slots — vertical home comfort, premium baby goods, post-regulation-safe beauty — instead of the things every reseller is already swarming.

II.

Each candidate ships with a forecast, not a screenshot

Margin-decay across the imitation curve, US INFORM / EU GPSR / DAC7 paperwork load, de-minimis import cost after Section 321 changes — evaluated before the SKU is shortlisted.

III.

Positioning nudges so you compete on identity

A short list is a list. A shortlist with branded framing is a defensible catalog entry — you ship a story before the marketplace giants compress the price.

Method · wk-of 02 Aug 2026

Four passes, ranked — never an infinite index.

A wider list is not a useful list. The Cratesmith workflow compresses the week’s noise into a moveable shortlist you can pick up Monday morning, with the paperwork already mapped.

Every shortlisted SKU carries
  • · Margin half-life in weeks
  • · Compliance & paperwork load (US / EU / cross-border)
  • · Landed-cost memo (de-minimis + tariff)
  • · Positioning angle for your branded catalog entry
  • · A walk-away list, so you don’t re-litigate the same losers
  1. step 01

    Sweep the demand surface

    Bestseller movement, search spikes and TikTok Shop surges across Amazon, Walmart Marketplace, Temu and Shopify — measured weekly, capped to the four surfaces your operator can actually stock.

  2. step 02

    Layer in supply pressure

    For every candidate we plot how fast the slot will be priced down — forecaster read, seller density, brand-trademark activity, inventory overhang. The output is a half-life for the margin, not a sentiment score.

  3. step 03

    Run compliance + landed-cost checks

    US INFORM, EU GPSR and DAC7 paperwork loads; de-minimis import-cost simulation after the Section 321 reform; tariff exposure; small-lot logistics. A SKU that hasn’t cleared every check never makes the shortlist.

  4. step 04

    Issue a curated shortlist

    A weekly digest — five to seven durable bets, ranked by margin half-life, with positioning angles and a red-line list of SKUs to walk away from.

Each candidate arrives with the regulatory background already triaged by region. Cratesmith is intentionally conservative — a SKU that has not cleared every applicable check never makes the shortlist.
