The cover page reads: California Workers' Compensation Uniform Statistical Reporting Plan-1995, Title 10, California Code of Regulations Section 2318.6, Effective September 1, 2026.
claim ca-usrp-1995-2318-6#c1The Memorandum regarding the September 1, 2026 revisions states that Part 1, Section I, Introduction, Rule 3, Effective Date, was amended to show that the effective date of the amended Uniform Statistical Reporting Plan is 12:01 AM, September 1, 2026.
claim ca-usrp-1995-2318-6#c2Part 3, Section III, Rule 1a: any business or operation specifically described by a classification shall be assigned to that classification. Rule 1b: any business or operation not described by a classification shall be assigned to the classification(s) most analogous from the standpoint of process and hazard.
claim ca-usrp-1995-2318-6#c3In determining the most analogous classification, Rule 1b directs consideration of factors that differ by activity, including for manufacturers the industry type, finished goods, raw materials, and types of tools and equipment and how employees use them; for stores the types of products sold, who purchases them and how they are sold; for service providers the type of services, who contracts for them and where they are provided; for construction or erection the types of structures, raw materials and equipment and the type of contractor's license required; and for agriculture the crops cultivated and animals raised, the methods used, and the machinery, tools and equipment used.
claim ca-usrp-1995-2318-6#c4Part 3, Section III, Rule 1c: any business or operation described by a classification defined as a Standard Exception shall be classified in the Standard Exception classification; however, when a Standard Exception is assigned to the basic business or operation, all employees not specifically included in the definitions for such Standard Exceptions shall be separately classified, all other conditions contained in the Plan notwithstanding. The worked example following Rule 1c assigns all operations of an investment firm to Classification 8810, Clerical Office Employees, except an employee who maintains the facility, who is assigned to Classification 9015(1), Building Operation - N.O.C. - all other employees.
claim ca-usrp-1995-2318-6#c5Part 3, Section III, Rule 2 (Single Enterprise): if the employer's business, conducted at one or more locations, consists of a single operation or a number of separate operations that normally prevail in the business described by a single classification, the entire exposure of the business shall be assigned to that single classification, and no division of payroll shall be permitted in respect to any other operation unless the applicable classification phraseology or other provisions of the Plan specifically provide for it.
claim ca-usrp-1995-2318-6#c6The Single Enterprise worked example describes a full service restaurant whose staff includes chefs, bakers, dishwashers, wait staff, janitors and car parking valets, plus a storage facility at an additional location holding restaurant supplies; because those operations normally prevail in the operation of a full service restaurant, Classification 9080, Restaurants - full service, applies to all of the employees.
claim ca-usrp-1995-2318-6#c7Part 3, Section III, Rule 3 (Multiple Enterprises): two or more distinct operations that do not normally prevail in the business described by a single classification are separately classified only if physically separated; if two or more distinct operations are not physically separated, they shall be assigned to the highest-rated classification applicable to the distinct operations conducted in the common workspace. Division of payroll is permitted only if the operation is not described by any General Inclusion, the division is not contrary to classification phraseology, and the division is not contrary to other provisions of the Plan.
claim ca-usrp-1995-2318-6#c8Part 3, Section IV lists eight Special Industry Classification Procedures: Aircraft Operation; Construction or Erection Work; Electronic Products Design and Manufacturing; Farms; Stores; Wrecking or Demolition and Building Raising or Moving; Labor Contractors; and Property Management/Operation.
claim ca-usrp-1995-2318-6#c9Part 3, Section IV, Rule 2 (Construction or Erection Work) is the location of the wording 'Operations for which separate records of payroll are not maintained shall be assigned to the highest rated classification applicable to the job or location if payrolls are kept separately by job within the policy period; otherwise, the highest rated classification shall be assigned based on the entire policy period.' This wording sits in the construction divided-payroll rule and is not the general recordkeeping rule.
claim ca-usrp-1995-2318-6#c10Part 3, Section IV, Rule 2a (Determination of Dual Wage Construction or Erection Classification): a classification that requires the regular hourly wage to equal or exceed a specified amount may be used only upon verification that the employee is paid an hourly wage that equals or exceeds the specified amount. For all employees other than salaried employees, determination of the regular hourly wage must be supported by original time cards or time book entries for each employee, or by a valid collective bargaining agreement that shows the regular hourly wage rate by job classification of worker; payroll for which an hourly wage determination cannot be reconciled to those records shall not be assigned to a classification that requires the regular hourly wage to equal or exceed a specified amount.
claim ca-usrp-1995-2318-6#c11Part 3, Section V, Rule 2 (Payroll Records): if the employer fails to keep complete and accurate records of the remuneration earned by all officers and employees in sufficient detail to permit the proper classification of payroll and to make them available for examination by the insurer, the total remuneration earned shall be assigned to the highest rated classification describing any part of the work.
claim ca-usrp-1995-2318-6#c12Part 3, Section V, Rule 3 (Division of Single Employee's Payroll): the remuneration of any one employee may be divided between two or more classifications only if the employer has maintained complete and accurate records supported by original time cards or time book entries showing separately, both by individual employee and in summary by operations performed, the remuneration earned by such employee. Division shall not be allowed in connection with Standard Exception classifications or if the division is contrary to classification phraseology. If the employer fails to keep such records, the entire remuneration of the employee shall be assigned to the highest rated classification applicable to any part of the work performed by the employee. Payroll may not be divided by means of percentages, averages, estimates, or any basis other than specific time records.
claim ca-usrp-1995-2318-6#c13Part 3, Section VI, Rule 1: the WCIRB has authority to inspect the premises of any employer for classification assignment purposes and is responsible for conducting a comprehensive inspection program to ensure that insurers use the proper classifications in reporting payroll and losses.
claim ca-usrp-1995-2318-6#c14Part 3, Section VI, Rule 2: if the WCIRB has made a classification assignment as the result of a WCIRB inspection, notice of the classification(s) assigned shall be published by providing the inspection report to either the insurer of record at the time the inspection was conducted or the insurer of record at the time the report is released, and the WCIRB shall provide a copy of the inspection report to the employer within 30 days from the date the inspection report is published. An insurer is not relieved of the obligation to report an applicable WCIRB classification assignment because of lack of knowledge that notice has been published by the WCIRB.
claim ca-usrp-1995-2318-6#c15Part 3, Section VI, Rule 3a: if the classification assignment represents a reclassification of the employer's operations that is not the result of a change of operations or a reallocation or assignment of payroll to existing classifications on the policy, the classification shall be published and effective as provided in Rules 3a(1) and 3a(2).
claim ca-usrp-1995-2318-6#c16Part 3, Section VI, Rule 3a(1): if the classification carries a pure premium rate higher than that of the erroneous classification, it shall be effective as of the effective date of the erroneous classification assignment provided (a) the classification assignment is published within three months of the effective date of the erroneous assignment, (b) the WCIRB was notified, in writing, within three months of the effective date of the erroneous assignment of a possible error, or (c) the WCIRB notified the insurer of record, in writing, within three months of the effective date of the erroneous assignment that the erroneous assignment was under review. Otherwise, the revised assignment shall be effective as of the date it is published, unless it is published less than three months prior to the expiration of the outstanding policy, in which case it shall be effective as of the inception date of the policy which replaces the outstanding policy.
claim ca-usrp-1995-2318-6#c17Part 3, Section VI, Rule 3a(2), first sentence: if the classification carries a pure premium rate lower than that of the erroneous classification, it shall be effective as of the inception date of a policy outstanding on the date the insurer of record is notified by the WCIRB, in writing, that the erroneous assignment is under review. Second sentence: the assignment also shall be applied as of the inception date of a policy that expired no more than twelve (12) months prior to the date the assignment was published or the insurer of record was notified by the WCIRB, in writing, that the erroneous assignment was under review, provided the erroneous assignment was applicable to such policy.
claim ca-usrp-1995-2318-6#c18Part 3, Section VI, Rule 3b: a classification assignment due to a change of operations shall be published and effective as of the date of the change of operations, regardless of the resulting pure premium rate. Rule 3c: a reallocation or assignment of payroll to existing classifications on a policy shall be effective as of the inception date of the policy.
claim ca-usrp-1995-2318-6#c19Part 3, Section VI, Rule 4a(3): each policy producing a final premium of less than $10,500 and developing exposure in a dual wage construction or erection classification that requires the regular hourly wage to equal or exceed a specified amount shall be physically audited, unless the policy is a renewal and the insurer physically audited one of the two immediately preceding policy periods.
claim ca-usrp-1995-2318-6#c20The Memorandum states that the September 1, 2026 revisions amend Part 3, Section V, Rule 1, Subrules j, k, l and m to adjust the minimum and maximum payroll limitations for executive officers, partners, individual employers and members of a limited liability company, to reflect wage inflation since those limitations were last amended in 2025.
claim ca-usrp-1995-2318-6#c21The Memorandum raises the annual payroll limitation from $165,100 to $171,600 for thirty-four separately listed classifications, each stated as reflecting wage inflation since the payroll limitation was last amended in 2025. The full set is: 9181 Athletic Teams or Athletic Facilities (for players, per player per season); 9610 Motion Pictures - production (for actors, musicians, producers and the motion picture director, per person); and, per employee, 7607(2) Audio Post-Production, 7607(1) Video Post-Production, 8803 Auditing, Accounting or Management Consulting Services, 8808 Banks, 8801 Credit Unions, 8749 Mortgage Bankers, 8743 Mortgage Brokers, 8822 Insurance Companies, 8820 Law Firms, 4512 Biomedical Research Laboratories, 8859(1) Computer Programming or Software Development, 8859(2) Internet or Web-Based Application Development or Operation, 8601(1) Engineers, 8601(2) Oil or Gas Geologists or Scouts, 8601(4) Forest Engineers, 8874(1) Instrument Mfg. - electronic - professional or scientific - hardware or software design or development, 8874(2) Computer or Computer Peripheral Equipment Mfg. - hardware or software design or development, 8874(3) Telecommunications Equipment Mfg. - hardware or software design or development, 8874(4) Audio/Video Electronic Products Mfg. - hardware or software design or development, 8874(5) Integrated Circuit and Semiconductor Wafer Mfg. - hardware or software design or development, 8874(6) Medical Instrument Mfg. - electronic - diagnostic or treatment - hardware or software design or development, 8874(7) Instrument Mfg. - non-electronic - scientific or medical - hardware or software design or development, 8839 Dental or Orthodontia Practices, 9043 Hospitals, 8834 Physicians' Practices and Outpatient Clinics, 4297(1) Electronic Pre-Press, 4297(2) Graphic Design, 8807 Newspaper, 7610 Radio, 8741 Real Estate Agencies, 9156 Theaters - dance, and 9151 Theaters - musical entertainment.
claim ca-usrp-1995-2318-6#c22The Memorandum eliminates certain classifications with their operations reassigned, including Classification 3070, Computer Memory Disk Mfg., eliminated due to low statistical credibility with its operations reassigned to Classification 3681(2), Computer or Computer Peripheral Equipment Mfg. - all other employees, and Classification 2102, Fruit or Vegetable Evaporation or Dehydrating, eliminated due to its limited statistical credibility with its operations reassigned to Classification 2111(1), Fruit or Vegetable Preserving. Classification 2111(3), Fruit or Vegetable Pickling, was also eliminated as an alternate phraseology for clarity and its operations reassigned to Classification 2111(1).
claim ca-usrp-1995-2318-6#c23The Memorandum lists twenty-five pairs of classifications whose hourly wage threshold was increased effective September 1, 2026, each stated as reflecting wage inflation since the threshold was last amended in 2024: 5185/5186 Automatic Sprinkler Installation, $33.00 to $36.00; 5403/5432 Carpentry, $41.00 to $46.00; 5201(2)/5205(2) Concrete or Cement Work - pouring or finishing of concrete floor slabs and concrete slab-type foundations, $33.00 to $36.00; 5201(1)/5205(1) Concrete or Cement Work - pouring or finishing of concrete sidewalks, driveways, patios, curbs or gutters, $33.00 to $36.00; 5190/5140 Electrical Wiring, $36.00 to $40.00; 6218(1)/6220(1) Excavation, $40.00 to $45.00; 6315(2)/6316(2) Gas Mains or Connections Construction, $40.00 to $45.00; 5467/5470 Glaziers, $39.00 to $43.00; 6218(2)/6220(2) Grading Land, $40.00 to $45.00; 5538(2)/5542(2) Heating or Air Conditioning Ductwork, $33.00 to $37.00; 5183(3)/5187(3) Heating or Air Conditioning Equipment, $32.00 to $35.00; 6218(3)/6220(3) Land Leveling, $40.00 to $45.00; 5027/5028 Masonry, $35.00 to $37.00; 5474(1)/5482(1) Painting or Wallpaper Installation, $32.00 to $36.00; 5474(3)/5482(3) Painting - water, oil or gasoline storage tanks, $32.00 to $36.00; 5484/5485 Plastering or Stucco Work, $38.00 to $42.00; 5183(1)/5187(1) Plumbing, $32.00 to $35.00; 5183(2)/5187(2) Refrigeration Equipment, $32.00 to $35.00; 5552/5553 Roofing, $31.00 to $33.00; 6307/6308 Sewer Construction, $40.00 to $45.00; 5538(1)/5542(1) Sheet Metal Work, $33.00 to $37.00; 5632/5633 Steel Framing, $41.00 to $46.00; 5446/5447 Wallboard Installation, $41.00 to $45.00; 6315(1)/6316(1) Water Mains or Connections Construction, $40.00 to $45.00; and 5474(2)/5482(2) Waterproofing, $32.00 to $36.00.

Re-fetched and re-verified 2026-08-31 over HTTPS with a browser user agent (WebFetch gets 403), HTTP 200, 3,336,865 bytes; full text extracted with pdftotext -layout (1,375,272 characters) and read directly. Cover page, the full Memorandum, Section III Rules 1 through 3, the Section IV rule list and Rules 2 and 2a, Section V Rules 2 and 3, and Section VI Rules 1 through 4 were all read in the extracted text. Standing corrections from the previous pass, all re-confirmed today against the extracted text: (1) the dual wage list was completed - the Memorandum increases the hourly wage threshold for twenty-five pairs of classifications, not only 5185/5186, and all twenty-five are enumerated with their old and new thresholds; (2) the Section VI, Rule 3 claim was split into Rules 3a, 3a(1), 3a(2), 3b and 3c, adding the 'Otherwise' fallback in 3a(1) and the second sentence of 3a(2), which extends a downward correction back to a policy that expired no more than twelve months before publication or written notice; (3) the Section VI, Rule 2 claim was narrowed to the rule's actual wording, which names either the insurer of record at the time the inspection was conducted or the insurer of record at the time the report is released. VERIFICATION PERFORMED THIS PASS: the count of dual wage threshold amendments was checked mechanically over the whole extracted document, not just the memorandum - the string 'hourly wage threshold from $' occurs exactly 25 times document-wide, and each occurrence was resolved to its classification pair; the enumerated list matches those 25 exactly, so the set is complete and no pair is missing. Section VI, Rule 3a(2) was re-read in full and both sentences are present as claimed; the rule number is current (Section VI, Rule 3 is titled 'Effective Date of Standard Classification Assignments' in this edition). Section III Rules 1a, 1b, 1c, 2 and 3, Section IV Rules 2 and 2a, Section V Rules 2 and 3, and Section VI Rules 1, 2 and 4a(3) were each re-read and each cited rule number matches the rule that actually carries the quoted wording in this edition. The 'highest rated classification applicable to the job or location' wording was located mechanically: it occurs exactly once in the document, inside Section IV, Rule 2, confirming the scope note below. CORRECTIONS MADE THIS PASS: (a) the memorandum claim was split into three, and the payroll limitation list was completed - the previous claim named nine classifications behind the word 'including', which understated the change the same way the dual wage claim once did; the Memorandum raises the $165,100 annual payroll limitation to $171,600 for thirty-four separately listed classifications, and all thirty-four are now enumerated, verified by resolving each of the 34 memorandum occurrences of 'from $165,100 to $171,600' to its classification; (b) the elimination claim was corrected to carry the plan's stated reasons (low or limited statistical credibility) and to add Classification 2111(3), Fruit or Vegetable Pickling, reassigned to 2111(1), which the earlier claim omitted; (c) two dual wage classification descriptions were corrected to the memorandum's own wording - the 5201/5205 pair is 'pouring or finishing of concrete' floor slabs and slab-type foundations and sidewalks, driveways, patios, curbs or gutters, and 5474(3)/5482(3) is 'Painting - water, oil or gasoline storage tanks', not 'Painting of'. The 5201/5205 and 8874 descriptions are abbreviated from longer official phraseologies and are not verbatim renderings. IMPORTANT SCOPE NOTE carried in the claims themselves: the phrase 'highest rated classification applicable to the job or location' appears only in Section IV, Rule 2 (Construction or Erection Work). The general rules use different wording (Section V, Rule 2: 'the highest rated classification describing any part of the work'; Section V, Rule 3: 'the highest rated classification applicable to any part of the work performed by the employee'). This edition is not in force on 2026-08-31; it takes effect at 12:01 AM on 2026-09-01, and the prose names the edition every time it relies on it. The title field uses ASCII hyphens where the official title is typeset with an em dash, so it is a normalized rather than verbatim rendering. Published: 2026-06-01 Effective: 2026-09-01
