Applies to establishments engaged in the manufacturing of products from animal substances such as glue, lard and tallow. Glue manufacturing begins by boiling animal substances, including skins and hoofs, in water until the materials are diluted and melted. The material dries as a residue and forms as a hard pure protein gelatin. Incidental operations include bone crushing, grinding and bagging of bone meal, the filling of solidified grease into drums from the oil settling tanks and the pressing, drying, pulverizing and bagging of tankage for fertilizer manufacturers. The traditional "hot" animal glue which is produced in flake form, requires a heated glue pot to keep it at a usable consistency. More modern forms are ready to use liquids. Glues come in three general forms: Ready-to-use, water mixed form, and waterproof types that are often two-part and must be sold in two separate container units. These come with directions to mix to specified proportions just before use. Ready-to-use types retail in bottles, cans and tubes. Tools and equipment used include, but are not limited to, boiling pots, scrapers and razors. This classification includes making or refining lard, which is the white solid or semisolid rendered fat from a hog, and tallow making. This process includes taking the hard fat from parts of the bodies of cattle, sheep or horses, separating it by melting from the fibrous and membranous matter and mixing the whitish solids for use in making candles, leather dressing, soap and lubricants.

This classification excludes establishments that manufacture synthetic glues such as acrylic base, contact cement, polyester, latex combination, epoxy sticks, polyethylene, polyvinyl, or cellulose nitrate or rubber base which are to be reported separately in classification 3701.

Applies to establishments engaged in manufacturing sausage. This process includes grinding, mixing, and blending cuts of meat with seasonings, spices, and fillers using grinders, mixers, pots, cooking tanks and meat cutting instruments. The mixture is stuffed into synthetic or natural casings or packed into forms. The product is often cooked in pressurized cooking tanks. The sausage is then cured by either pumping or injecting a curing solution into the meat or dry rubbing a curing substance into the meat and immersing the meat in a brine solution. Curing solutions usually contain one or more chemicals, such as sodium or potassium nitrate, ascorbate, or erythorbate, and water. The meats are then allowed to cure for up to 40 days. Curing may be followed by a period of several hours to several days in a temperature controlled smokehouse. The final product may be packaged, canned, placed in jars, or frozen.

This classification excludes dealers of natural sausage casings which are to be reported separately in classification 4301-19; meat products manufacturing which is to be reported separately in classification 4301-12; retail meat and poultry dealers which are to be reported separately in classification 3303; and the handling of livestock which is to be reported separately in the applicable classification.

Applies to establishments engaged in packing house operations which include the handling and slaughtering of livestock and the preparation of fresh meat and meat products. Animals are moved through a system of chutes to a conveyor system which takes them through a stunning machine and then into the slaughtering area. Work is performed with the use of hoists, knives, scissors, razors, scrapers, meat chippers, cleavers and hydraulic dropper/spreaders. After slaughtering, the blood is drained, collected and stored. The carcasses are then dipped into a scald tank and conveyed to dehairer machines and the hides are removed. After carcasses have been inspected and weighed, they are placed in blast freezers for several hours and then moved to a cooler. Carcasses are sawed or cut into portions and specific cuts of meat including those that will be used in other products such as cold cuts, sausages, and hot dogs. The products are then placed in cardboard boxes and loaded onto pallets. This classification includes incidental rendering, lard refining, butter substitutes manufacturing, washing of casings, sausage manufacturing, salting of hides, cooking of offal (waste), processing of the viscera manually or by machine, and fertilizer manufacturing when done by employees of an employer subject to this classification. Some of the prepared meats are packed in cans, bottles, or jars, sealed and cooked in vats. Meat packing and processing operations may be consolidated or may be in different locations.

This classification excludes establishments primarily engaged in sausage manufacturing which are to be reported separately in classification 4301-10; dealers of natural sausage casings which are to be reported separately in classification 4301-19; meat products manufacturing which is to be reported separately in classification 4301-12; slaughterhouse only operations which are to be reported separately in classification 4301-22; custom meat cutting which is to be reported separately in classification 4302; retail meat and poultry dealers which are to be reported separately in classification 3303; and wholesale meat and poultry processors/dealers which are to be reported separately in classification 3304.

Applies to establishments engaged in meat products manufacturing, including canning or dehydrating. Products include, but are not limited to, frankfurters, bologna, head cheese and meat loaf. No handling or slaughtering of livestock is performed by employers subject to this classification. Meats are received in halves, quarters or individual fresh cuts. Cuts of meat are washed, soaked in brine, smoked, pickled, corned, and/or otherwise cooked. Meat products are bottled in jars, bottles, or cans and sealed. Meat trimmings may be chopped, ground, mixed, smoked, boiled, or stuffed in sausage casings. Machinery and equipment includes, but is not limited to, mixing, cutting, and bottling equipment or tools.

Applies to establishments engaged in the shredding and baling of peat moss. This includes the cleaning, sorting and packaging of peat moss to be used as mulch, plant food (fertilizer), soil amendment, fuel or decorative uses such as in floral arrangements.

This classification excludes establishments engaged in the digging or stripping of peat from the surface of bogs with use of mechanical equipment which are to be reported separately in classification 0112 and the picking of moss by hand in a forest which is to be reported separately in classification 4802.

Applies to establishments engaged in tannery operations which involve tanning and dressing raw hides for sale to dealers or manufacturers of leather or fur products. (Taxidermists often send hides to a tannery rather than treating them at their own shops.) Hides are received from outside sources, washed in caustic soda, borax and soda to clean, soften and preserve them. Excess flesh and tissue is removed from hides by fleshing machines which resemble a band saw mounted on a table. Any additional fleshing is done by scraping with a hand knife. Hides are then softened by agitating in a lime solution to remove all or part of the hair or fur, softened by agitating paddles using a variety of chemicals mixed with cornmeal and treated with a solution of sulfuric acid. Tanning is then done in revolving drums containing a mixture of water, salt, sodium bicarbonate and chromium sulfate. Drying may be done using a gas fired oven depending on the type of hide. Shredded hide may be baled and sold to glue makers. Tanned hides are split, dyed and finished. Tears in the hide are hand sewn.

This classification excludes hide or leather dealers, establishments engaged in hide pelting, and taxidermists which are all to be reported separately in classification 3708.

Applies to establishments engaged in the sales and distribution of natural sausage casings to others. Casings are animal intestines received from packing houses or rendering plants. Wholesale dealers wash, dry, sort and package casings for distribution.

This classification excludes establishments engaged in the manufacture of sausage which are to be reported separately in classification 4301-10.

Applies to establishments engaged in rendering operations not covered by another classification (N.O.C.). Rendering is the act of reducing or melting down fat by heating. The raw animal materials such as, but not limited to, discarded fat, bone trimmings, meat scraps, blood, grease and feathers are collected from farms, stockyards, slaughterhouses, butcher shops, supermarkets, restaurants, meat and poultry stores, ranches, feed lots or animal shelters and brought to the rendering plant. The hides are removed and stored for shipment to hide dealers and tanneries. Carcasses are cut into workable sizes and placed into tanks. Steam passes directly into the materials being cooked. The grease is drawn off and meat and bones drop into a slush box. The slush is then pressed to remove more water and grease before going to steam pressure dryers. In some plants this is all performed with one piece of equipment. Tools and equipment may also include crushers, hashers, grinders, hoggers, prebreakers, blow tanks, conveyors, bucket elevators, pumps, steam-heater batch corkers, dryers, screw presses and waste water treatment equipment. In addition, other products such as cod liver oil may be produced, depending on the basic material being rendered. Regardless of the type of rendering system being used, all fish oils and animal grease or tallow are pumped into receiving or settling tanks. Barrels, drums or tank cars are filled for shipment to manufacturers of assorted products such as soap, and fatty acid products such as cosmetics, lubricants, paints and plastics. Edible tallow is used in margarine and other foods as regulated by the USDA. This classification includes the crushing, grinding, pressing, drying, pulverizing, and bagging of dried slush or tankage to produce fish or bonemeal, and feed concentrates for livestock and poultry and fertilizer.

This classification excludes establishments engaged as packing houses which are to be reported separately in classification 4301-11 and establishments engaged as slaughterhouses which are to be reported separately in classification 4301-22.
