Shipping Glossary: Shipping has a language all its own. Between dimensional weight, FOB terms, chassis charges, door tags, and ECT box ratings, the jargon can make even a simple parcel feel complicated. This Shipping Glossary is ParcelPath’s plain-English reference hub for the terms, fees, and abbreviations you run into when you buy a label, hand off a freight pallet, or track a package across a border. Every definition is written for real shippers, not dictionary editors, so you can read an entry, understand exactly what it means for your shipment, and move on.
Understanding the terminology is also how you stop overpaying. The same carriers that charge full retail at the counter offer dramatically lower rates through commercial accounts, and ParcelPath passes those discounts straight to you: up to 85% off UPS and up to 89% off USPS retail pricing, with no monthly fees or volume minimums. Knowing what a residential surcharge, dimensional divisor, or delivery exception actually is helps you avoid the fees that quietly inflate your bill. Use the sections below to jump to the part of the shipping world you need, follow the links into each sub-glossary, and then put what you learn to work the next time you create a label.
Weights & Measurements
Carriers price packages on whichever is greater: actual weight or dimensional (volumetric) weight, so knowing what your item really weighs is the first step to an accurate rate. Underestimating weight leads to adjustment fees after pickup, while overestimating means you quote customers too high and lose sales. This section collects practical weight references for everyday items so you can fill in a label with confidence.
Think of this Shipping Glossary as a working reference you return to whenever a fee or term is unclear. Every Shipping Glossary entry is written for real shippers, and the Shipping Glossary links out to deeper sub-glossaries so you can go as far as your shipment requires.

General Logistics
Logistics is the connective tissue of shipping: the rules, policies, and habits that determine whether your packages move smoothly or get stuck. The smartest savings often come not from a single trick but from understanding how rates, regulations, and routing fit together. This section covers the broad questions every shipper eventually asks.
Dig into the General Logistics glossary for a wide range of how-to and policy explainers, including these favorites:

- 7 Key Shipping Policies and Regulations to Know

Services & Carrier
Not every shipment needs overnight air, and not every carrier is right for every lane. Service levels range from economy ground (cheapest, slowest) to expedited air, and regional carriers can beat the national giants on price and reliability in their coverage areas. Matching the service to the shipment is one of the easiest ways to cut cost without hurting delivery promises.

Tracking & Delivery
Tracking events tell a story, but only if you can read them. A door tag means a delivery was attempted; a delivery exception signals a hold-up that may need your action; and a “delivered” scan on a package you never received kicks off a different process entirely. Knowing what each status means helps you respond fast and protect both your customers and your claims.
The Tracking & Delivery glossary decodes scan statuses and tells you what to do when things go wrong:

- Tracking a Stolen Package: 7 Recovery Steps
- 7 Ways to Handle Delivery Exceptions and Claims
Customs & International
Crossing a border adds a layer of terminology, from Incoterms like FOB shipping point versus FOB destination, which decide exactly when ownership and risk transfer, to signature confirmation rules that differ outside the lower 48. Getting these details right keeps shipments out of customs limbo and protects you from unexpected liability.

- Does Ground Service Go to Puerto Rico? Rates & Options
- Can I Get Signature Confirmation for International Shipments?
Rates & Pricing
Two identical boxes can cost wildly different amounts to ship depending on the destination, the surcharges that apply, and whether you use flat-rate packaging. A residential delivery surcharge, for example, is added to most home deliveries, while USPS Flat Rate ignores weight entirely within size limits. Learning where the money goes is how you stop leaking it.
The Rates & Pricing glossary breaks down surcharges, flat-rate options, and cost-saving tactics:

- How to Ship a Medium Flat Rate Box
- Living Cheap Ideas for Smart, Effortless Savings
Freight & LTL
When a shipment is too big for parcel but doesn’t fill a trailer, it moves as LTL (less-than-truckload) freight, a world with its own vocabulary: freight class, consignee billing, chassis charges, and blind shipping. Preparing pallets correctly and understanding who pays which fee prevents reclassification charges that can dwarf the base rate.
The Freight & LTL glossary explains pallet prep, billing, and accessorial fees:

- What Is Consignee Billing: Simplify Shipping Payments
- Chassis Charges: Rates & Fees Guide (Daily Rate)
Packaging
The right box does two jobs at once: it protects your item and it keeps you out of dimensional-weight penalties. Ratings like 32 ECT tell you how much stacking force a box can take, while girth (the distance around a parcel) determines whether carriers treat it as oversize. Measure correctly and you ship cheaper and safer.
The Packaging glossary covers box strength, measurement, and dimensional calculations:

- Girth Calculator: 5 Steps for Perfect Package Measurements
- Package Measurements and Calculations Made Easy
Labels & Documentation
A label is more than an address: it carries the postage, the routing barcode, and the tracking number that ties a shipment to your account. Choosing the right printer (thermal versus inkjet), formatting the address correctly, and understanding identifiers like a shipper number all prevent the rejected labels and misroutes that cost time and money.
The Labels & Documentation glossary covers printing, addressing, and shipping IDs:

Frequently Asked Questions: Shipping Glossary
What is dimensional (DIM) weight?
Dimensional weight is a pricing method that charges you based on the space a package occupies rather than how much it physically weighs. Carriers calculate it by multiplying length x width x height and dividing by a dimensional divisor. If that number is higher than the actual weight, you pay the DIM weight. This is why a large, lightweight box can cost more than a small, heavy one, and why right-sizing your packaging directly lowers your bill.
What is the difference between a delivery exception and a delivery attempt?
A delivery attempt means the carrier tried to deliver but no one was available, often resulting in a door tag and another try the next business day. A delivery exception is broader: it flags any unexpected event that may delay the package, such as a bad address, weather, customs hold, or damage. Exceptions sometimes require you to take action, like correcting an address, while a simple attempt usually resolves itself on the next route.
What does FOB mean on a shipment?
FOB stands for “Free On Board” and defines the point at which ownership and risk pass from seller to buyer. With FOB shipping point (origin), the buyer takes responsibility the moment the goods leave the seller’s dock, so the buyer covers freight and any in-transit loss. With FOB destination, the seller retains responsibility until the goods arrive. Knowing which applies tells you who pays for shipping and who files a claim if something goes wrong.
What is LTL freight?
LTL, or less-than-truckload, freight is shipping for loads too large for parcel carriers but too small to fill an entire trailer, typically one to six pallets. Multiple shippers’ goods share the same truck, and pricing depends on freight class, weight, distance, and accessorial fees such as liftgate or residential delivery. Properly palletizing and accurately classifying LTL freight prevents costly reweigh and reclassification adjustments.
