A catalog that could not ship: rebuilding around dangerous-goods rules
Sellable SKUs 22 → 74
Two thirds of the brand's products were stuck in dangerous-goods review, restricted from fast fulfillment or simply not stocked. The advertising was fine; the plumbing was not.

The challenge
The brand made ninety-eight products and could reliably sell twenty-two of them. The rest sat in one of several holds: documentation rejected by the dangerous-goods review, storage limits that capped how much flammable stock could be held at a time, or a classification that excluded them from the fast fulfillment programs the category's shoppers filter by.
Nobody owned the problem because it did not look like a marketing problem. Meanwhile every growth plan the brand wrote — new campaigns, new content, new launches — was being drawn up for a catalog that was three quarters unavailable, and the shortfall was blamed on advertising performance for two years running.
Our approach
We treated the fulfillment constraint as the growth strategy, because it was.
- Safety data sheets rebuilt to specification — the majority of rejections were formatting and missing-field failures, not the products themselves.
- Classification reviewed product by product, with several items reclassified correctly into a less restricted handling tier.
- Split fulfillment design — the genuinely restricted items routed through a merchant-fulfilled process with realistic handling times, so they stay sellable instead of disappearing.
- Replenishment rebuilt around storage limits, sending smaller and more frequent shipments rather than hitting the cap and stopping.
Timeline
Unblock
- All 98 safety data sheets rebuilt and resubmitted
- 41 SKUs cleared review at the first attempt
- Storage limits mapped against actual sales velocity
Reroute
- Restricted items moved to a merchant-fulfilled process
- Handling times published honestly on the listings
- Replenishment cadence changed from monthly to weekly
Grow
- Advertising extended across the newly sellable catalog
- Out-of-stock days down 81%
- Revenue passes $300k a month
The results
Sellable SKUs went from 22 to 74 and revenue more than tripled to $307k a month.
Nothing in this project was a marketing idea. Rebuilding paperwork to a specification, correcting classifications and rerouting the genuinely restricted items released a catalog that had been finished and warehoused for years. Out-of-stock days fell 81% once replenishment was designed around the storage caps instead of colliding with them every month.
“Two years of monthly performance reviews, for products that literally could not ship.”
