1. Product must contain no less than 28% and no more than 32% magnesium chloride by weight. Product is to be tested in accordance with Section VI of these specifications.

2. Weight per gallon will be established according to the specific gravity and percentage of magnesium chloride contained in the product bid. Product is to be tested in accordance with Section VI of these specifications.

3. Product will contain the corrosion control inhibitor in quantities not less than those indicated by the Supplier. The finished deicing product, including corrosion inhibitors, must be completely accomplished at the original manufacturing plant location prior to loading on the transport. Post adding of corrosion inhibitors or any other ingredients after the product has left the original manufacturing plant, and splash https://clearroads.org/qualified-product-list/ mixing, are unacceptable. Product is to be tested in accordance with Section VI of these specifications.

II. BID PROCESS

A. Bids must be accompanied by an analysis of the product being bid. This analysis must contain the following information for each type of product being bid:

1. Corrosion test data obtained according to NACE Standard TM0169-95 as modified by

PNS.

2. Analytical results of all constituents for which limits have been set by these Specifications.

3. Specific gravity chart with correlating weight percentage and freeze point information presented in 1% increments beginning with a five percent solution. The chart must contain information up to, including, and exceeding by 5% (or the solubility limits of the product) the concentration being bid.

B. Bids will be accompanied by the most recent detailed product specification sheet and Material Safety Data Sheet (MSDS) including the MSDS of the inhibitor. All documents must be clearly legible.

III. ORDERS, DELIVERIES, AND INVOICING OF PRODUCTS

A. SDDOT will place all orders by either phone or email. The official order date will be the date of the phone call or email transmittal if sent by the SDDOT before 2:00 p.m., or the next day if sent by the SDDOT after 2:00 p.m. (All order times reflect Purchaser’s time.)

The Supplier will call or email back to the SDDOT within 2 business hours a confirmation of receipt of the order and an estimate of the order shipment date.

B. Supplier will make all deliveries during normal working hours (Monday through Friday between the hours of 7:00 a.m. and 4:00 p.m. CST or MST, respective of the time zone in which the delivery is received). Supplier will provide a minimum of 24 hours advance notice of delivery time, unless otherwise requested or agreed to by the SDDOT. Any delivery made without proper advance notification or outside of the established delivery times, unless otherwise authorized by SDDOT in advance, will be assessed a liquidated damages assessment of 10% of the purchase price of the product. Any liquidated damages assessed pursuant to this section will be in addition to any liquidated damages assessed pursuant to Section VI for deviations from these specifications.

C. Supplier will make all deliveries within seven (7) calendar days of the order date. If the Supplier does not deliver within this required time, Supplier will pay SDDOT a liquidated damages assessment of 5% per day for each day of delay, beginning with day 8, and continuing until delivery is made. If the Supplier has not made satisfactory arrangements with the SDDOT Maintenance Shop (Point of Delivery) personnel by the required delivery date, the SDDOT may, at its sole discretion, order from another vendor and the Supplier will pay SDDOT for any additional cost. Any pattern of late deliveries, which in the sole determination of the SDDOT Operations Support Program Manager causes operational issues for SDDOT, will be grounds for the SDDOT to terminate the contract.

D. During the months of November 1 through April 1, each inclusive, if the SDDOT places an order larger than 2 transports for any location, the Supplier will deliver at least 2 transports of that order within the specified time period or liquidated damages will apply.

If the Supplier cannot deliver the entire order at once, the balance must be delivered on daily deliveries beginning immediately after the first delivery, until the order is fulfilled, or as otherwise agreed to by the SDDOT.

E. During the months of November 1 through April 1, each inclusive, SDDOT may place orders, clearly designated by SDDOT as “emergency orders.” Delivery of an emergency order within 48 hours of placement of the order will carry a 10% premium above the contract price. The 10% premium is to compensate Supplier for the short notice expenses Supplier may incur and to offer an incentive for Supplier to make every effort to make delivery within the shortened time frame. Supplier will notify SDDOT within 2 hours of placement of an emergency order stating an expected delivery time. If the expected delivery time is not within the 48-hour time frame, SDDOT may go to alternate suppliers in an attempt to fill the order. If the Supplier attempts to make the 48-hour delivery, but does not do so, SDDOT will pay the “as bid” contract price.

F. Supplier will communicate any objection to liquidated damages assessed for a late delivery or specification deviation within seven (7) calendar days of receipt of the liquidated damages assessment. The Supplier will communicate the objection in writing, to the Operations Support Program Manager. The decision of the Operations Support Program Manager to accept or to deny the objection will be final.

G. Supplier will be responsible for all necessary equipment to transfer liquid chemical products to SDDOT’S storage tanks. SDDOT will fit each storage tank with a two-inch male pipe fitting or a large non-connective opening to allow for unloading of product.

H. Supplier will include a current and clearly legible MSDS with each delivery.

I. Supplier will make available an anti-foaming agent for use as needed, at no additional charge to the SDDOT, to control foaming during loading, unloading, and agitation of liquid chemical products.

J. The bill of lading for each shipment must contain the following information:

1. Name of product.

2. Supplier and manufacturer of product.

3. Delivery destination.

4. Total number of units being delivered.

5. Total weight of delivery using a certified scale ticket.

6. The Lot number of product being delivered. The lot number must enable SDDOT to track a delivered product back to its manufacture point, date of manufacture, and specific batch.

7. Transport information—Name of transporting company, tank, trailer, or rail car number, point and date of origin.

8. The Percent Concentration and Specific Gravity, and the test results of both.

K. The invoice must include all the above and the following information:

1. A copy of the original bill of lading.

2. Contract unit of measure.

3. Total number of units delivered.

4. Contract unit price for product delivered.

5. Total price for the units delivered.

IV. FUEL COST ADJUSTMENTS

A. The Purchaser will base the price change on a four- or five-week average, to the nearest hundredth of a dollar ($0.01) using the rounding procedures from the DOT Materials Manual, located on the Purchaser’s website. The Purchaser will use the “Weekly Retail On Highway Diesel Prices” for “All Types” using Midwest Prices as reported in the Energy Information Administration (EIA) of the US Department of Energy weekly publication. A 4-week average will be used for months having 4 Mondays and a 5-week average will be used for months having 5 Mondays. The amended contract price will be reviewed monthly during the last week of the month by the Operations Support Office of the SDDOT;

therefore, initiating a new contract price effective for deliveries made the following month through the Office of Procurement Management. Should fuel prices increase or decrease beyond 10% from the base price of $3.439 as determined from the EIA publication – Midwest Div. on June 3, 2025, the contract price will be amended as follows:

Calculations have shown that fuel consumption is approximately 50% of the total transportation costs for the delivered loads. Therefore, when a fuel cost adjustment is needed according to the terms of this contract, the following procedure will be used. A base price of $.40/gal has been assumed for magnesium chloride being delivered to the sites. The total transportation costs are then determined by subtracting the base price for alternative chemical deicers and magnesium chloride, $.40/per gal., from the Supplier’s bid price for that delivery location. Then 50% of that amount will be used for the calculated fuel cost.

Example: The bid price of magnesium chloride is $1.60/gal. Then the transportation cost would be ($1.60-$.40) or $1.20/gal. Then 50% of that amount or $.60/gal will be used for the calculated fuel cost.

The percentage applied to the calculated fuel cost would be the amount over 10% to the nearest 0.1%.

Example: The current four- or five-week average fuel price, rounded to the nearest hundredth of a dollar, is $4.30/gal, and the published price as of June 3, 2025, is $3.439/gal. The total percentage increase in fuel price is $4.300 - $3.439 = $0.861/$3.439 or 25.04%. Therefore, the amount applied to the calculated fuel cost would be 25.04% - 10% or 15.04%.

Therefore, the cost increase applied to the contract price would be 15.04% times the calculated fuel cost.

Example: $.60 x 15.04% = $.090/gal, therefore, use $.090/gal increase. So, $1.60/gal plus $.090/gal for an amended contract price of $1.690/gal.

The same calculations would hold true if the cost of fuel were to fall more than 10% below the published price on June 3rd, 2025.

B. Split Loads: Any time a Purchase Order directs that a load be split between more than one delivery location, Supplier will charge no more than $100.00 as a drop fee charged to each location following the first delivery. Supplier will confirm any drop shipment fees in its order confirmation.

V. FIELD INSPECTION, UNLOADING, SAMPLING AND TESTING

All product is subject to field and laboratory inspection, sampling, and testing on an as delivered basis. Inspection, sampling, and testing may be done at the sole discretion of the SDDOT. The Supplier will not off load any product without affording the SDDOT an opportunity to conduct the inspection, sampling, and testing. Off-loading of product without affording the SDDOT an opportunity to conduct the inspection, sampling, and testing will deem the delivered product non-compliant and subject to total rejection. The Supplier will only off load product without inspection, testing, and sampling by the SDDOT, when SDDOT point of delivery representative grants prior approval.

A. FIELD INSPECTION

Before allowing any product to be unloaded, SDDOT’S personnel will be allowed the opportunity to perform the following procedures, and any other tests or inspections as may be deemed necessary in the sole discretion of SDDOT:

1. Document and maintain records on all deliveries, including those that are rejected.

2. Check to assure that the product is being delivered according to the terms of the contract. This includes but is not limited to the following:

a. Date of the order.

b. Date and time of delivery.

c. Verification of advance delivery notification.

d. Was the product delivered within allowable times?

e. Name of the delivery company and license plate numbers of the semi and trailer(s).

f. Are any liquidated damage assessments required?

g. Is the product being delivered the product that was ordered?

h. Document all procedures prior to unloading of product.

i. Verify that all papers required of a delivery are present, complete, and legible.

Is the bill of lading or the invoice accurate, complete, and legible?

Legible and current MSDS sheet.

Certified weight slip.

3. Verify separation or non-separation of product.

4. Visually inspect the load to determine if there are any obvious reason(s) why the load should be rejected.

5. No precipitate or flocculation in liquid products will be allowed in excess of the specification limits. Product portraying these or other uncharacteristic traits when delivered may be immediately rejected at the option of the SDDOT.

6. Any problems should be noted at the point of delivery by agency personnel, documented, and relayed to their agency representative for action.

B. SAMPLING AND TESTING

One or more samples may be taken from the delivered shipment for laboratory testing after the shipment has passed the initial inspection and is approved for unloading. The sample(s) will be used for testing at the SDDOT’S expense to ensure product quality. Test results from the South Dakota Agricultural Laboratory will be final and conclusive. Test results will be forwarded to the Supplier within 2 business days of receipt from the testing laboratory.

1. A one gallon (or 2 half gallon) sample will be taken from the transfer hose in three equal parts. Each part will be mixed together with the other parts to make up the one-gallon sample to be submitted to the laboratory for testing. The three equal sample portions will be collected during unloading as the first third, the second third, and the last third of the product being delivered. If the trailer or pup has compartments, the three equal samples will be taken from only one compartment to complete the sample.

2. Samples sent to the laboratory will be tested for conformance to specifications. If the product is suspected of containing deleterious materials which may be harmful to people, equipment, the roadway, or the environment, samples may be tested for those materials and properties as well.

VII. LIQUIDATED DAMAGES FOR DEVIATIONS FROM SPECIFICATIONS

Liquidated damages will be assessed based on product costs. Determination of the liquidated damages to be applied will be based on the testing procedures as outlined in the specifications.

Liquidated damages are to be accumulatively applied. In other words, a shipment failing two tests will be assessed the sum of the liquidated damages of the two tests. This summation is to continue until zero payment is due but cannot continue into the negative.

The Supplier will be required to replace any rejected product, plus any stored product contaminated by the rejected product, at the Supplier’s cost. The Supplier will remove and replace any rejected product with product that meets the product specifications, together with handling and transportation charges, at no additional cost to the SDDOT. Removal includes the removal of all product contaminated by the non-specification product. SDDOT personnel will establish the amount of stored product that was contaminated.

Two shipments per contract year of product found by SDDOT to be beyond any specification range will be grounds for contract termination.

SDDOT will not pay for product delivered until SDDOT receives satisfactory test results from its testing lab. SDDOT may use the product prior to receipt of test results. Use does not constitute acceptance. SDDOT reserves the right to price adjust or reject all product received.

No forbearance on the part of the SDDOT will constitute a waiver, nor bind the SDDOT to a waiver of any similar or succeeding breach of same or any other term or provision of these specifications.
