On July 24th at 00:01 Eastern Time, a new round of tariffs officially came into effect. According to Article 301 of the 1974 Trade Act, differentiated tariffs ranging from 10% to 12.5% are imposed on 60 economies worldwide on the grounds of "forced labor". Mainland China and Hong Kong are classified as the top tier at 12.5%. This tariff is not a temporary measure, but a long-term institutional arrangement based on Section 301. For shippers exporting to the United States, there are several things that must be clarified now.
What exactly is this tariff
First, clarify the basic framework. On July 23, the Office of the United States Trade Representative (USTR) issued a notice stating that, in accordance with Section 301 of the 1974 Trade Act, 60 economies worldwide have not established and effectively enforced legal provisions prohibiting the importation of forced labor products, and therefore additional tariffs will be imposed.
Tax rates are divided into three levels:
First tier, 12.5%. Applicable to all other surveyed economies, including mainland China, Hong Kong, Japan, South Korea, Switzerland, Vietnam, India, Australia, and 46 others. Chinese goods exported to the United States correspond to the official CBP tax item 9903.05.31, and unless otherwise exempted, an additional 12.5% ad valorem tax will be levied.
Second tier, 10%. Applicable to 17 economies that have established partial forced labor control mechanisms, including Argentina, Bangladesh, Cambodia, Canada, Indonesia, Malaysia, Mexico, the United Kingdom, etc.
Third level, special treatment. EU and Taiwan, China Province of China: if the MFN tax rate is lower than 10%, it will be supplemented to 10%; If it is equal to or higher than 10%, the 301 tariff will be 0. Japan, South Korea, Switzerland: MFN tax rates below 12.5% are supplemented to 12.5%, while those equal to or higher than 12.5% are zero.
This tariff covers over 99% of the total US imports, an unprecedented scale.
Legal 'shell changing': from temporary to long-term
On the surface, the tax rate on China this time is only 2.5 percentage points higher than before (previously it was a temporary 10% tariff under Article 122, now it is 12.5%). But the essence is completely different - this is a qualitative change from a temporary tool to a long-term system.
Tracing back this path:
The first step was that the US government initially imposed "equivalent tariffs" under the International Emergency Economic Powers Act (IEEPA), which was ruled unconstitutional by the Supreme Court.
The second step is to quickly switch to Article 122 of the 1974 Trade Act, which imposes a temporary tariff of 150 days (i.e. the previously expired 10% global surtax).
Step three, after the expiration of Article 122, move out Article 301 to "take over".
The legal basis is constantly changing, and the essence of imposing tariffs remains consistent. Analysis has pointed out that this "shell swapping" strategy has another purpose: legal redundancy enhances the resilience of the system, even if one legal basis is ruled invalid by the court, the government can quickly switch to another, making it more difficult for the tariff system to be overturned as a whole. USTR Greer publicly stated on July 24th that "the new tariff measures can withstand legal scrutiny.
The most crucial point is that the new 301 does not replace the old 301, and is subject to additional taxation
This is the easiest point to make mistakes and also the most impactful for cost accounting.
The new 301 tariff will not replace the historical 301 tariff on China, and the two will be levied together. That is to say, if your product was previously subject to a 301 tariff (the 7.5% or 25% batch), now you need to add an additional 12.5% on top of that.
After July 24th, the basic formula for the total tariff of Chinese goods exported to the United States is:
Basic Tariff (MFN)+New 301 Tariff (12.5%)+Old 301 Tariff (if any)+Double Anti Tariff (if any)
There is an important exception: the 232 tariff does not overlap with the new 301. If the goods have already been subject to 232 national security tariffs (steel, aluminum, copper and their derivatives, automobiles and parts, etc.), the new 301 tariffs will not be added.
Use three specific cases to illustrate how significant the differences are:
Case 1: Ordinary toys. Assuming the basic tax rate of the customs code is 0, which is not within the scope of exemption, a new 301 needs to be levied.
Total tariff=0+12.5%=12.5%
Case 2: Women's pants (textile). Customs code 6204.61.05, with a basic tax rate of 7.6%. If it falls within the coverage of the old 301, an additional 7.5% will be levied. If it is not within the exemption scope of the new 301, an additional 12.5% will be levied.
Total tariff=7.6%+7.5%+12.5%=27.6%
Case 3: Steel products. Customs code 8302.50.00, basic tax rate 0, falls within the scope of 232 tariff coverage.
Due to the non overlapping of 232 and the new 301, the total tariff will not be increased by an additional 12.5%, and will be implemented according to the established tax rate of 232.
Similarly, for exports to the United States, there is a significant difference in tariff increases for different categories. Textiles, which were already covered by the old 301, have the highest comprehensive tax rate when combined.
Transition period clause: July 28th is the critical deadline
The policy provides a brief transition window: if the goods are loaded at the port of origin and initiated the final mode of transport before 12:01 AM Eastern Time on July 24, 2026, and complete domestic sales declaration or warehouse pickup procedures by 12:01 AM Eastern Time on July 28, the additional tariff will not be imposed.
That is to say, goods shipped before July 24 and cleared before July 28 will still be subject to the old tax rate. After July 28, all goods will be taxed at the new rate.
There is a practical risk here: due to the impact of cross-border logistics transit cycles, packages collected and shipped around July 20 may arrive at the destination after the new policy takes effect, potentially leading to disputes over tariff differences. Some logistics providers have already introduced transitional protection policies for such in-transit shipments. If your shipment falls within this time window, promptly confirm the arrival and clearance times with your customs broker or freight forwarder to see if it can still qualify for the transition period.

Which products can be exempted
Not all goods are subject to the 12.5% surcharge. The following categories are exempt:
First, goods in transit (those meeting the aforementioned transition period conditions).
Second, goods already subject to Section 232 tariffs: steel, aluminum, copper and their derivatives, passenger vehicles and light trucks and their components, medium and heavy-duty vehicles and their components, etc. These goods will be taxed at the established Section 232 rates without additional Section 301 tariffs.
Third, other exempt categories: civil aircraft and engine components, pharmaceutical-related goods, wood products, and semiconductor-related goods.
Fourth, materials that may lead to domestic supply shortages in the U.S., products that could disrupt economic operations, goods that cannot be produced in sufficient quantities domestically with inadequate alternative supply, and commodities for which tariff hikes are ineffective in eliminating "unreasonable practices"-these categories require application for certification.
The complete exemption list can be viewed on the CBP website (search for "Forced Labor HTS LIST"). It is recommended to cross-check with your own HS codes rather than assuming "my category must be exempt.".
What does it mean for the cargo owner
Costs need to be recalculated
This is the most direct. After the addition of the new 301 and the old 301, the comprehensive tax rate for many categories is 2.5 percentage points or even higher than before. The quotation and profit model previously calculated based on a temporary tariff of 10% now have to be recalculated according to the new tax rate. Especially for categories covered by the old 301, such as textiles, the impact is the greatest when combined.
Bond limit may not be sufficient
This is easily overlooked. The US Customs requires importers to have a Customs Bond amount equal to 10% of the previous year's tariffs, taxes, and other fees. After the addition of the new 301 tariff, the total annual tariff will increase. If the existing Bond quota does not keep up, the customs may detain the goods in the customs clearance process until the difference is made up before releasing them. It is recommended to contact the customs broker after July 24th to recalculate according to the new tax rate and expand the gap as soon as possible.
Stricter declaration of origin
The differentiation of tariffs (12.5% in China and 10% in some Southeast Asian countries) will stimulate some people to have the idea of "changing the country of origin declaration". Reminder: If the goods are actually produced in China and the COO (country of origin) fills the land in the country where the warehouse is located, there is a high probability of triggering CBP refund verification, with a regular delay of 3 to 5 days; In serious cases, it may be deemed as false declaration of origin and face fines. The country of origin is filled in with 'where was it manufactured', not 'where was it shipped'.
The negotiation on tax reduction between China and the United States is progressing
This time it's not just about increasing taxes. China and the United States are still pushing for a $30 billion equivalent tax reduction list, involving categories such as clothing, shoes, hats, household goods, consumer electronics accessories, ordinary light industrial products, and non sensitive medical consumables. These categories are currently subject to an additional 7.5% to 25% of the original 301 tariff, and are expected to return to the MFN base tax rate after the tax reduction is implemented.
However, it should be noted that at this stage, we are still in the stage of consultation and soliciting opinions, and no official list has been released. Everything will be based on the official landing documents. Don't treat 'possible tax reduction' as' already reduced 'when scheduling goods.
What the shipper should do now
Firstly, use the customs code to check the tax rate. Log in to hts.usitc.gov and check if your code is included in the newly added collection scope in column 99 of Chapter 99. Refer to the exemption list to confirm if you are eligible for exemption. This step is more important than anything else - if you don't investigate clearly, all subsequent cost accounting will be wrong.
Secondly, recalculate pricing and profits. Calculate the new comprehensive tax rate using the formula of "basic tariff+new 301+old 301 (if any)", and compare it with the previous cost structure to see if the profit can still be sustained. If you can't hold on, either adjust the price, negotiate with the customer for sharing, or consider changing the product category.
Thirdly, check the Bond limit. Contact the customs broker to recalculate the annual tariff amount according to the new tax rate. If the bond is not enough, expand it as soon as possible. Don't wait until the customs clearance is seized to discover it.
Fourth, confirm the customs clearance time for goods in transit. If the shipment is made before July 24th, let's see if we can clear customs before the transition period ends on July 28th. The provinces that can catch up are 2.5 percentage points, and those that cannot catch up are subject to the new tax rate.
Fifth, pay attention to the progress of China US tax reduction negotiations. If the category you are working on falls within the scope of the equivalent tax reduction list (clothing, shoes, hats, home furnishings, consumer electronics accessories, etc.), there may be tax reduction benefits. But at this stage, it's just a negotiation. Don't arrange the goods based on the cost after tax reduction in advance. Let's wait for the official list to be implemented before making a decision.
Sixth, Southeast Asian transit should be cautious. Tariff differentiation (12.5% for China and 10% for some Southeast Asian countries) will make people want to pursue transshipment. But with the increasingly strict identification of origin in the United States, simply changing the label without changing the "substantial processing" will still be recognized as originating in China. If we really want to transfer production capacity, we need to build factories and put them into operation, not engage in logistics transshipment.
Epilogue
The tariff switch on July 24th only nominally added 2.5 percentage points to China, but in essence it was a qualitative change from a temporary tool to a long-term system. After adding the old 301, the comprehensive tax rate for many categories is significantly higher than before. For shippers exporting to the United States, the most important thing now is not to complain, but to clarify tax rates, calculate costs, fully utilize exemptions, and diversify risks. Tariffs are at the policy level, and freight forwarders only transmit them. What you can truly control is your own cost structure and category selection.
