Running a small business that ships low-weight merchandise, say 10 T-shirts or small hardware from China to the United States, made logistics costs easy. The U.S. provided for a large shipping discount of 40 percent to 70 percent.

Such generosity came from U.S. membership in the Universal Postal Union (UPU). Founded in 1874, the UPU is the international postal organization in Switzerland, committed to smoothly running the international postal system.

In 1969, the UPU's developed country members implemented discounts for poor nations when shipping small parcels. China then was isolated with few outward shipments.

As a result, the shipping cost of a face cream was more affordable for American consumers from China than it was from Los Angeles. Today, however, China delivers more than 1 billion small packages a year to the U.S., but the special discount treatment continued.

Then there came change. The Trump administration announced U.S. withdrawal from the UPU as of Oct. 17, 2018. The objective was to arrive at competitive and fair global shipping rates.

This move showed the Trump administration's willingness to quit multilateral agreements judged unfavorable to U.S. interests. Although the UPU withdrawal process takes one year, U.S. deep discounts for Chinese packages ended immediately.

Now China Post has introduced a new Express Mail Service. It raised the price of packages to the U.S. from $30 to $34 for the first 0.5 kilograms shipped. Who pays, and who benefits?

The United States Postal Service (USPS) can use higher payments from China. But transshipments through other nations and competition will lead to reduced shipping volume.

The price advantage of many Chinese e-commerce vendors will decline. The higher cost of shipping reduces this advantage even further. Most endangered are eBay type, international vendors. Sellers who compete on price alone face higher cost and more competition.

To survive, it will become a new practice to find alternatives for product and service delivery both for processes as well as markets.

Adjusting the rules for new conditions makes sense. Few parameter conditions have remained static for 144 years. The UPU should get ready for a significant restructuring. What applies to China, the U.S. and other relationships, applies to other nations as well.

One should expect a further exploration of antiquated subsidies that have been bypassed by new market conditions. Such tracking can identify new opportunities for change and innovation.

De-subsidization will create market alternatives based on new forms of delivery. Such adjustments will be cost analyzed and competitively compared to achieve higher efficiency.

Legislators and internationally active framers of distance trade, such as the World Bank and the World Trade Organization, can use this opportunity to pinpoint, develop and scale-up models that reflect transport-cost-sensitive sectors and practices.

In addition to greater accuracy and fairness, the president's initiative for higher prices can lead to higher capabilities, more efficiencies and better services. It's a good start!
