Dried Brewer's Yeast Packing: Jumbo Bags, 25 kg Bags and Container Loads

In short: dried brewer's yeast ships in two formats. Jumbo bags of 600 to 1,200 kg suit plants with bulk intake and a forklift at the dock. 25 kg bags suit plants that dose by hand or split a load across several sites. A full container carries 24 to 26 MT, depending on the pallet configuration. The choice changes handling cost at your plant far more than it changes the product.

This guide is for purchasing managers, plant managers and importers buying brewer's yeast for pet food, aquafeed and livestock feed. It covers the two packing formats TBESBY ships, how each one loads into a container, and the packing details worth fixing in the purchase order before the first shipment.

Which packing formats are available?

How much fits in a container?

A full container of TBESBY dried brewer's yeast carries 24 to 26 MT. The figure moves with the pallet configuration: palletised cargo gives up some payload for faster, safer unloading, while floor-loaded cargo carries more product per container. Tell us how your warehouse receives goods and we will quote the loading plan with the price, so freight per tonne is known before you commit.

Dried brewer's yeast is a light, free-flowing powder, so the payload is set by volume and by the road weight limits at destination as much as by the container itself. Buyers in markets with strict axle limits should give the maximum gross weight they can accept at the port of discharge.

How should you choose between the two?

• Intake equipment: a big-bag discharge station or bulk intake pit points to jumbo bags. A premix room with scales points to 25 kg bags.
• Inclusion rate: at 1 to 3% of a recipe, a plant making 100 tonnes a day uses 1 to 3 tonnes of yeast a day, which is one to five jumbo bags. Below a few hundred kilos a day, 25 kg bags are easier to manage.
• Onward distribution: importers who resell part-loads usually take 25 kg bags on pallets, because each pallet is a saleable unit.

• Lot identification: each unit carries the lot number that appears on the certificate of analysis, in either format.

What should the purchase order say about packing?

Fix six points in writing: packing format and net weight per unit, palletised or floor-loaded, pallet type and whether heat treatment marking is required at destination, label language and content, lot marking that matches the certificate of analysis, and the maximum gross weight per container. The documents that travel with the cargo are listed in our guide to importing brewer's yeast from Vietnam.

Which standards apply to the packaging itself?

Three sets of rules sit behind a packing line on a quotation, and a buyer who knows them can write a tighter purchase order.

• Jumbo bags. ISO 21898 is the international standard for flexible intermediate bulk containers used for non-dangerous goods. It defines the safe working load printed on the bag label and the safety factor the bag is tested to: 5:1 for single-trip bags and 6:1 for standard reusable bags. A bag rated for 1,000 kg on a 5:1 factor has been type-tested to carry five times that load.
• Wooden pallets. ISPM 15, the phytosanitary standard of the International Plant Protection Convention, covers wood packaging thicker than 6 mm in international trade. Pallets must be heat-treated to a core temperature of 56 °C for at least 30 minutes, or treated by another approved method, and carry the IPPC mark. Customs in most importing countries check for the mark.
• The container. The maximum gross mass and payload are stamped on the safety approval plate on the container door. In practice the road weight limit between the port and your plant is often lower than the container limit, which is why the purchase order should state the heaviest gross weight you can receive.

A worked example: from inclusion rate to packing format

Take a dry pet food plant producing 60,000 tonnes of kibble a year with brewer's yeast at 2% of the recipe. Annual yeast use is 1,200 tonnes, or 100 tonnes a month. At 25 MT per container that is four containers a month, and in 1,000 kg jumbo bags it is 100 bags a month, about five a working day. One forklift driver handles that at a big-bag station in minutes. The same tonnage in 25 kg bags would be 4,000 bags a month, each opened and emptied by hand.

Now take a treat manufacturer using 5 tonnes a month across several small recipes. That is 200 bags of 25 kg, which operators can weigh out by the scoop and reseal. Five jumbo bags would cover the same volume, but each opened bag would stand part-used for a week. For this buyer, 25 kg bags keep the product closed until the day it is used. Published feeding guidance puts brewer's yeast at 2 to 5% of pig and poultry diets (Blair, 2007, cited by Feedipedia), so the same arithmetic applies to a feed mill with larger numbers.

What should the warehouse check on arrival?

1. The container seal number against the bill of lading, before the doors are opened.
2. The number of units and the net weight against the packing list.
3. The lot number on each unit against the certificate of analysis.
4. The IPPC mark on wooden pallets, where your market requires it.
5. A retained sample from each lot, labelled and stored for the shelf life of the product.
