Why quart sizes ship faster and cheaper than gallons — and why it’s not a fee we charge.
The chemical itself doesn’t change — only the container size. DOT law draws a line at 1 quart / 1 liter.
Containers at or below 1 quart / 1 liter qualify for the DOT Limited Quantity exemption under 49 CFR § 173.150. No hazmat paperwork, no carrier hazmat surcharge, no ground-only restriction.
Containers over 1 quart / 1 liter are automatically classified as hazmat for transport — not by Alliance, by the same regulation (49 CFR § 173.150). Carriers then apply their hazmat rates, which cover special packaging, paperwork, and certified handling.
FedEx, UPS, and LTL carriers charge a flat hazmat surcharge plus higher base rates for DOT-regulated freight. These are the carrier’s rates — we pass them through at cost.
Hazmat containers ship inside tested UN-spec boxes with absorbent and, for some products, a required overpack. That’s real material cost before the freight is even quoted.
Every hazmat shipment needs a signed Bill of Lading with the proper shipping name, hazard class, and UN number. Drivers must be hazmat-certified. That overhead rolls into the rate.
Most of our chemicals come in quart and gallon SKUs of the same formula. Four quarts equal one gallon by volume — and because quarts ship under the Limited Quantity exemption, the delivered cost is usually lower and the delivery window is shorter. Always check total delivered cost at checkout; savings vary by chemical class, destination, and carrier.
We use ShipperHQ to pull live rates from our carriers (FedEx, UPS, LTL partners) at checkout. What you see is what they charge us — we pass it through at cost, no markup, no hidden fee.
ShipperHQ hits the carrier API in real time when you hit checkout. Weight, dimensions, hazard class, your ZIP — all go into the quote the moment you see it.
The carrier's line item is exactly what the carrier sent us. We don't build in a handling fee, a fuel surcharge we invented, or a dimensional-weight "adjustment." If you've ever been surprised by a line item, it wasn't us.
Two customers in the same city can see different rates for the same SKU. That's not us — it's carrier dimensional weight, hazmat classification (quart vs gallon), distance from the nearest terminal, and lane-specific LTL base rates. ShipperHQ shows you the reality.
Central Texas gets our own local truck (no LTL stacking). Farther out, we hand off to FedEx, UPS, or LTL partners on the lane that actually makes sense for your freight. ShipperHQ picks the cheapest valid option; you can override at checkout if you want faster.
The honest part: We make our margin on the chemistry, not the freight. When quart shipments are cheaper than gallons of the same chemical, it's because the carrier's hazmat math says so — not because we charge extra on the bigger size. If a rate looks wrong, call us at (512) 365-6838 and we'll run it with you line by line.
No. Alliance Chemical adds no hazmat fee to your order. When gallon-sized shipments cost more than quart shipments, that difference is entirely the carrier’s hazmat rate — the same rate FedEx, UPS, and LTL carriers charge any shipper. We pass it through at cost.
DOT regulation 49 CFR § 173.150 exempts containers at or below 1 quart / 1 liter from full hazmat rules under the “Limited Quantity” provision. A single gallon crosses that threshold and triggers full hazmat handling: ground-only freight, UN-spec packaging, certified drivers, and a carrier hazmat surcharge. Four separate quart containers stay under the threshold for each package.
Yes, in almost every case. Limited Quantity exempt containers are eligible for standard air services (next-day, 2-day) in addition to ground. A few specialty products may still have air restrictions; those are flagged on the product page when they apply.
Generally no. Once a container crosses the Limited Quantity threshold it’s treated as DOT hazmat, and most carriers restrict hazmat to ground service. Bulk orders going to the same address sometimes qualify for LTL freight, which is still ground.
Yes — individual states (and some cities) layer their own restrictions on specific chemicals: certain acids, concentrated peroxides, and controlled precursors. These don’t change the DOT classification, but they can block shipment to some ZIPs entirely. See our chemical availability by state guide for the per-chemical breakdown.
We don’t decide — DOT does. The hazardous materials classification, packaging requirements, and Limited Quantity threshold all come straight from 49 CFR § 173.150. Our job is to honor the rule and ship compliantly.
