01
Dim-weight isn't the right ruler
Dense supplement parcels weigh more than they cube. Carriers using generic dim factors over-bill them every shipment.
Industries · Supplements
Dense parcels, weight-billed, subscription-led.
Supplement bottles are short, heavy, and dense. They get dim-billed against generic factors that don't fit. Combined with subscription cadence and recurring addresses, the negotiation profile is unusually strong — and rarely worked.
Where the money leaks
Three problems we see in every supplements audit.
02
Subscription churn from late delivery
Auto-ship customers cancel after the second late box. SLA refunds are unfiled.
03
FDA-flagged products complicate carrier choice
Some carriers add documentation surcharges for nutraceuticals. Often unnegotiated.
Our playbook
Four levers, specifically for supplements.
01
Cubic / weight-tier routing
USPS cubic and dense-weight tiers win supplement parcels cleanly. Wire them into the rate-shop.
02
Subscription drop contracts
Predictable monthly drop volume negotiated as recurring volume, not ad-hoc shipments.
03
Address validation at print
Recurring addresses get re-validated against the commercial database to prevent residential misclassification.
04
SLA refund automation
Late-delivery refunds tracked and filed weekly. Direct retention impact on subscription cohorts.
