Exclusions: Classification 0307 excludes:

• Worker hours engaged in sheet metal fabrication shop operations, which are reported separately in classification 3404. If records are not maintained for dividing worker hours between classifications, these hours must be reported in the highest rated classification as described in WAC 296-17-31017(4);

Note:

When a contractor's business is assigned a manufacturing shop or plant classification such as classification 3404, all shop and yard operations are reported in the manufacturing shop or plant classification and the special exception classification 5206 is no longer applicable to the contractor's business.

• Worker hours engaged in duct cleaning work, which are reported separately in classification 1105. If records are not maintained for dividing worker hours between classifications, these hours must be reported in the highest rated classification as described in WAC 296-17-31017(4);

• Worker hours engaged in other sheet metal installation or sheet metal construction, which are reported separately in classification 0519. If records are not maintained for dividing worker hours between classifications, these hours must be reported in the highest rated classification as described in WAC 296-17-31017(4).

Additional considerations for 0307:

• Classification 0307 is a construction industry classification (see WAC 296-17-31013);

• In most cases, contractors cannot have a store classification in addition to classification 0307, unless store operations are their principal business. To determine if a contractor can also have a store classification such as classification 2009 or 6309, apply the multiple classification rule (WAC 296-17-31017). If a contractor does not qualify for a store classification and if the work meets the restrictions described in the exception rule (WAC 296-17-31018) and the classification descriptions (chapter 296-17A WAC), the contractor may report employees working in a display area or showroom in classification 5206 or 6303.

Subclassifications:

For administrative purposes, classification 0307 is divided into the following subclassifications:

0307-01 Heating, ventilation, air conditioning, refrigeration and furnace systems: Installation, service or repair.

0307-05 Wood, pellet or gas stove: Installation, service or repair.
