How Chemical Shipping Works

Why quart sizes ship faster and cheaper than gallons — and why it’s not a fee we charge.

In stock, not in theory

If it’s listed, it’s on our shelf

We sell what we physically stock at our Taylor, Texas warehouse — not a catalog of items we order after you buy. No phantom inventory, no backorders, no four-week lead times on listed products. When a product page shows In Stock, it means a real unit is on the shelf, ready for the next outbound truck.

Most in-stock orders ship in 1–2 business days Order cutoff: Mon-Thu 2 PM CT / Fri 12 PM CT Ships from Taylor, TX

On the rare occasion a listed item is temporarily unavailable, the product page says so plainly and gives you our direct line (512-365-6838) for restock timing. We won’t quietly take an order we can’t ship.

The two-path rule

Every chemical has two shipping paths. Size decides which one you get.

The chemical itself doesn’t change — only the container size. DOT law draws the line by container size: 1 liter for most flammable and corrosive liquids, 5 liters for the milder Packing Group III ones.

Quart & liter sizes

Limited Quantity exemption

For most flammable and corrosive liquids (Packing Group II), containers of 1 liter or less qualify for the DOT Limited Quantity exception under 49 CFR § 173.150 and § 173.154. Packing Group III liquids qualify up to 5 liters, so a gallon jug of those can too. No hazmat paperwork, no carrier hazmat surcharge, no ground-only restriction.

  • Ships ground or air
  • Standard carrier rates — no surcharge
  • Typically 1–3 business days
  • Order four quarts → same volume as a gallon, usually cheaper delivered
Gallon & larger

DOT hazmat classification

Containers above the Limited Quantity cap for the product’s packing group (1 liter for Packing Group II, 5 liters for Packing Group III) ship as fully regulated hazmat — not by Alliance’s choice, by the same regulations (49 CFR § 173.150 and § 173.154). Carriers then apply their hazmat rates, which cover special packaging, paperwork, and certified handling.

  • Ground shipping only (no air)
  • Carrier hazmat rates apply — passed through at cost
  • UN-spec packaging, absorbent, overpack when required
  • Alliance adds no hazmat fee or markup
Where the cost comes from

Why gallons cost more to ship than four quarts of the same chemical

01

Carrier hazmat rates

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.

02

UN-spec packaging

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.

03

Paperwork & certified handling

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.

Smart-buying tip

Need a gallon? Consider four quarts.

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.

How we quote shipping

The number at checkout is the carrier's number

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.

Live rates, not estimates

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.

No Alliance markup on shipping

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.

Where the variance comes from

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.

Your ZIP, your lane

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.

Frequently asked

Questions we hear most

Does Alliance charge a hazmat fee?

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.

Why does my gallon cost more to ship than four quarts of the same product?

DOT’s “Limited Quantity” provision (49 CFR § 173.150 for flammable liquids, § 173.154 for corrosives) caps each inner container at 1 liter for Packing Group II products. A single gallon crosses that cap and triggers full hazmat handling: ground-only freight, UN-spec packaging, certified drivers, and a carrier hazmat surcharge. Four separate quart containers stay under it. Packing Group III products have a 5 liter cap, so for those a gallon jug can still ship as Limited Quantity.

Can quart and liter sizes ship by air?

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.

Are gallons ever eligible for air?

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.

Do state rules ever override the DOT rules?

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.

How does Alliance decide which sizes are hazmat?

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.
