Part of Insurance by Industry: What Actually Decides Your Risk
Insurance by industry mistakes that start with the wrong trade label
Insurance by industry mistakes: nine ways a trade label stands in for a description of activities, and what to put in writing instead.
Buying insurance by trade goes wrong in a particular way. The label is right, the package is named after your industry, and the broker knows the sector. The gap is still there.
The label was never the thing being insured. What is insured is a description of activities. The insurance by industry mistakes below are all versions of letting the label stand in for the description.
Nine of them, roughly in the order they occur.
What to take away
- Insurers price a description of what you do. The name of your trade is a shortcut to it, not a substitute for it.
- The side line, the seasonal job, and the favor for a customer are where trade packages stop reaching.
- A subcontractor's certificate is a statement about their policy, not cover for you.
- Classification is worth an argument. It moves more of the price than anything else you can influence.
When the program is first arranged
1. Describing yourself by label. Writing "contractor" or "consultant" on an application and letting the underwriter fill in the rest. Two businesses using the same word can differ on whether they work at height, whether they subcontract, and whether they touch anything structural, and those differences drive the price and the wording. A roofer doing steep-slope residential repair and a roofer doing commercial flat roofs land in different classes, and a "consulting" firm that installs equipment it designed is not the consulting firm that only advises. Describe activities, not identity. The reasoning behind that is set out in the industry guide.
Before you sign the application
- Describe activities, not identity
- Read which lines are bundled
- List side and seasonal work separately
- Ask about each exposure individually
2. Buying the package because it names your trade. A program built for your sector (roofing, trucking, staffing, restaurants) usually fits better than a generic form. It is still a bundle, and what it bundles was decided by somebody modeling a typical member of the trade. Read which lines are in it and which of your exposures are not addressed at all.
3. Assuming the trade endorsements cover the side line. The endorsements that make a package sector-specific were written for the sector's main activity. The thing you do on the side, or seasonally, or for one customer as a favor, is exactly what falls outside them. List those separately and ask about each one. Every endorsement carries a form number and an edition date, and the list of what is attached sits on the policy's schedule of forms and endorsements. Ask for that schedule in writing and read it, rather than trusting what the package is called.
While it is running
4. Letting the classification go stale. The class was right when you bought the policy and the business has moved. Nobody revisits it, because it sits on the declarations page looking like an administrative code. It is not administrative; it is the sentence the price was built on, and an audit or a claim is the usual way it gets revisited. Workers' compensation class codes come from the National Council on Compensation Insurance (NCCI) in most states and from a state rating bureau in the rest, and general liability classifications come from ISO, now part of Verisk. A premium audit checks your payroll records, the duties behind each job title, and what you paid subcontractors who carry no coverage of their own.
While the policy is running
- Revisit the classification when the business moves
- Split payroll by duty, not habit
- Flag any job in another state
- Verify subcontractor coverage, not just certificates
5. Splitting payroll by habit rather than by duty. Where compensation cover assigns classes by the work each person does, allocating payroll by job title or by who sits where produces a number nobody can defend. Your own records are the evidence, and OSHA's injury and illness recordkeeping material is a fair guide to what a defensible record looks like. What the workers' compensation policy asks of an employer is a separate subject worth reading in full.
6. Taking one job in another state. A single delivery, installation, or site visit across a line can bring a different regulator, a different compensation regime, and a wording question about territory. The standard workers' compensation policy handles other states in Part Three, Other States Insurance, and a state where you take work has to be listed there or added before the job starts. Four states (North Dakota, Ohio, Washington, and Wyoming) run monopolistic funds, where the state fund is the only source of workers' compensation coverage and a private policy will not respond to work performed there. It is one of the few changes that is easy to make and easy to forget in the same week.
7. Treating a subcontractor's certificate as protection. A certificate says a policy existed on the day it was issued. It does not say the policy covers the work being done for you, that you are an additional insured, or that anyone will still be insured next month. The form in circulation is ACORD 25, and the fields worth reading are the named insured (the legal entity you actually hired, not a trade name), the policy dates, the limits, the description of operations, and whether the additional insured and waiver of subrogation columns are marked. The form says on its face that it is issued for information only and confers no rights. Where a contract shifts risk to a subcontractor, the strength of that arrangement depends on an indemnity clause and on endorsements that actually exist: additional insured status on ISO form CG 20 10, a waiver of subrogation on CG 24 04, and primary and non-contributory wording. Check them against the subcontractor's schedule of forms, not against the certificate.
At renewal, and when comparing
8. Comparing two packages as though they held the same lines. One trade package includes property, another does not; one includes an endorsement for completed work, another leaves it out. The totals are comparable only after the contents are made the same. Where property is in the bundle, what it is measured against is its own subject in the commercial property guide, and the general habit of lining up structure before price is in the renewal reading guide.
9. Staying in a program after it stopped fitting. Programs are built for a sector and can be withdrawn when the sector's results turn, and they also drift: the endorsements change edition, the appetite narrows, and the business that fit at inception has grown into something else. Ask each year what the market's current appetite for your class is and where the broker saw it.
What the nine have in common
Each substitutes a category for a description. Categories help, so insurers use them. They are approximations, so the description must sit underneath.
For physical exposure, not advisory, the boundary is in the general liability guide. For neither, talk to a licensed broker who read your activity list, not your business name.
Your state insurance department licenses the insurers and intermediaries involved and can confirm whether a market proposed to you is admitted where you are. The California Department of Insurance, the Texas Department of Insurance, and their counterparts in the other states each run a licensee lookup, and the National Association of Insurance Commissioners (NAIC) maintains the directory that leads to each one. The department does not decide what your class should be; that is an underwriting judgment, and it is one you are entitled to have explained.
Common questions
My business genuinely does several things. Which trade am I?
Whichever the insurer is told, which is why the telling matters. Put the full activity list in writing, ask which classification each market proposes and why, and keep the answer with the policy.
Can I challenge a classification I think is wrong?
You can ask for the reasoning and present the activity description that supports a different one. It is an underwriting decision, and a broker who can show the market a clear description is the person to make the argument.
Is a sector program always better than a general policy?
Usually it fits better. It also carries the risk of withdrawal and the risk that your business has quietly stopped being typical of the sector. Both are questions to ask each year rather than once.
We have never had a claim. Does any of this matter?
The mistakes are invisible until there is a claim, which is the whole difficulty. The cost of checking is an afternoon; the cost of finding out the other way is decided by somebody else.
