Kanzaki Specialty Papers and Mitsubishi International: The Discount a Rival Wanted Gone

Thermal fax paper price fixing charges alleged that suppliers coordinated higher prices through meetings and telephone calls. A separate indictment described what that could mean for one paper converter: a supplier complained about a rival’s discount, and the lower offer disappeared. If you work in paper sales or purchasing, the event to recognize is the instruction that changed what a customer could buy.

The Justice Department’s July 14, 1994 announcement described criminal charges against Kanzaki Specialty Papers, its former president, Mitsubishi Corporation and Mitsubishi International Corporation. The antitrust charges concerned agreements to fix and raise North American thermal fax paper prices in 1991 and 1992. The department said the charged conspiracy raised prices by approximately 10%.

The defendants agreed to plead guilty. The announcement attributed the investigation to the Justice Department’s Antitrust Division, the Canadian Bureau of Competition and the Canadian justice department. The alleged price fixing reached an ordinary business supply, used primarily by small businesses and home fax machine owners.

The Paper Passed Through Several Hands

Thermal fax paper has a chemical coating that produces an image when a print head applies thermal energy. Manufacturers make it in jumbo rolls, and converters cut those rolls into smaller finished rolls for fax machines, certain medical printing equipment and other uses.

The separate criminal indictment described jumbo rolls approximately 40 to 50 inches wide and weighing up to 2,000 pounds. It identified Rittenhouse, a converter in Park Ridge, Illinois, as the customer whose discounted offer was allegedly targeted. The indictment charged executives of Mitsubishi Paper Mills and Kanzaki Paper Manufacturing, each with oversight of part of the fax-paper business.

According to that indictment, Japanese manufacturers typically sold specific quantities to trading houses in Japan for named U.S. customers at specified prices. The trading houses shipped the paper to their U.S. subsidiaries, which delivered it to customers or briefly stored it in warehouses. The manufacturer’s name stayed on the paper throughout the chain.

That distribution arrangement put pricing decisions upstream of the company presenting the offer. The indictment described the manufacturers’ role this way:

For a pricing employee, that distinction matters. The person sending the quote may be carrying out a manufacturer’s instruction, while someone at the manufacturer knows how that instruction was decided. Following the offer back through the trading house brings both decisions into view.

A Supplier Complaint Reached the Rival’s Price

The indictment alleged a sequence that began with a discount already reaching the customer. Rittenhouse primarily bought fax paper from Kanzaki Specialty Papers and Mitsubishi International. Kanzaki Specialty Papers complained to its parent, Kanzaki Paper Manufacturing, that Mitsubishi International was offering and selling paper to Rittenhouse at discounted prices.

The indictment put Rittenhouse’s fax-paper purchases in 1991 at approximately $10 million, against approximately $100 million in total U.S. fax-paper sales that year. This was a substantial customer buying from both sides of the alleged arrangement.

The charged executives then allegedly met to discuss that discount. One oversaw Mitsubishi Paper Mills’ business importing fax paper through trading houses, while the other supervised Kanzaki Specialty Papers and its pricing decisions. The indictment alleged that they agreed Mitsubishi Paper Mills would have its trading houses, Mitsubishi Corporation and Mitsubishi International, withdraw the discounted prices offered to Rittenhouse.

The alleged agreement then became a sales instruction. Mitsubishi Paper Mills directed the trading houses to increase the offer price for additional fax paper, Mitsubishi International refused further sales at the discounted price, and Rittenhouse bought paper at increased prices. The charged conduct ran from at least June through at least December 1991.

The customer still had suppliers to call. What the indictment alleged was that those suppliers had interfered with the cheaper alternative before the next purchase. The buyer wants a better price. A competing supplier complains the price is already too good.

The lost discount gives this story its point. Price competition can disappear through the withdrawal of an offer the customer has already received. An employee who knows why that offer was withdrawn can explain a decision that the final invoice alone would never show.

What Can a Whistleblower Add?

A whistleblower can connect the supplier contact to the changed instruction and the customer’s purchase. In this case, the indictment identified price notices, invoices, shipment reports and billing documents moving between Japan and the United States. Those records place the alleged agreement inside a working import and sales business.

For someone seeing similar conduct, the useful connection is between the earlier offer and the reason it changed. A trading-house employee may know which manufacturer instructed the sales desk to withdraw a discount. A manufacturer employee may know about the rival complaint or meeting that preceded the instruction. A converter’s buyer may know what was offered, when it was withdrawn and what the next purchase cost.

We examine the communications and transaction records together. The account is stronger when it explains which paper, which customer and which additional purchases the instruction covered. An instruction to raise a price becomes much more revealing when someone knows that a rival’s complaint set it in motion.

The shipment records matter for the same reason. In the indictment’s account, the manufacturer specified quantities for particular customers, and trading houses moved those goods through the distribution chain. Connecting a price notice to those shipments can help identify the purchases affected by the instruction, rather than leave the account at a general complaint about expensive paper.

The Price Pattern and the Decision Behind It

Pricing data can point toward a transaction worth examining, while people inside the business can explain the decision behind it. A review of detection methods in the construction industry makes that distinction useful beyond any one product. The 2018 paper Review of Collusion and Bid Rigging Detection Methods in the Construction Industry, published in the Proceedings of the Creative Construction Conference, describes statistical and other proactive methods as sources of indirect evidence and reports from people with knowledge of the conduct as sources of direct evidence. It argues that the approaches complement each other.

Applied to a paper-pricing inquiry, that means the change in the numbers and the explanation for it belong together. A converter can see the discount vanish. Someone inside the supplier may know that a competitor requested its removal. The indictment’s alleged complaint, meeting, instruction and refusal to discount describe that connection.

The Bumble Bee story shows the same commercial point in another product. The government’s filing in the criminal case against its former chief executive described coordination over both list-price increases and promotional net prices. For a sales employee, a restriction on promotions can matter as much as a new price sheet. In the paper allegation, the lower price disappeared through the trading house. In the tuna account, promotional pricing was part of the coordination.

How We Assess Paper-Pricing Conduct Today

For someone seeing similar paper-pricing conduct today, we assess the reward question around the information they hold and the transactions affected. Our experts assess how that information fits the antitrust whistleblower rewards program established by the Justice Department and Postal Service agreement.

Where the pricing arrangement reaches government purchases, we also examine the bids, invoices and payment claims for a False Claims Act case. A whistleblower case under the False Claims Act can pay 15% to 30% of what the government recovers. We work through that government-payment connection with you, alongside the supplier communications that explain the price.

You Know Who Changed the Offer

If you know which supplier contact made a discount disappear, speak with our whistleblower experts about the paper-pricing decisions you saw. We develop the case with you, bring in antitrust whistleblower lawyers who understand pricing agreements and government-payment claims, and stay beside you through the process.
