50% Tariffs Took Effect Yesterday! Rio Grande Port Faces Impact: How Chinese Shipowners Respond ?

50%关税昨日生效！里奥格兰德港面临冲击，中国船东如何应对？

On July 31st, local time, US President Trump signed an executive order on " reciprocal tariffs , " placing Brazil under a 10% tariff. This order, with a seven-day wind-down period, took effect at midnight on August 7th. The 10% tariff imposed in this order will be added to the 40 % additional tariff imposed on Brazil in an executive order signed by Trump on July 30th. This will result in a 50% surcharge on some Brazilian goods exported to the US, on top of the most-favored-nation (MFN) base rate.

When the tariff stick hits coffee, aircraft and metal products, Brazil's ports are likely to be affected. Rio Grande Port, located at the southern tip of Brazil, is the core seaport of Rio Grande do Sul . Today, we will take a deeper look at this port.

当地时间7月31日，美国总统特朗普签署有关“对等关税”的行政令，巴西被列在10%关税税率一档。此次行政令设7日缓冲期，将于8月7日零时生效。此次行政令中的10%关税，将与7月30日特朗普签署的行政令中对巴西加征40%额外关税叠加生效。这将导致部分巴西输美商品将在最惠国待遇（MFN）基础税率之上，多加50%附加税。

当关税大棒砸向咖啡、飞机和金属制品，巴西的港口都有可能受到冲击，位于巴西南端的里奥格兰德港（Rio Grande）作为南里奥格兰德州的核心出海口，今天便深入了解一下这个港口。

Advantages of Rio Grande

Geographical location and transportation network

As one of the most important maritime hubs in southern Brazil, the Port of Rio Grande serves as the core seaport for the state of Rio Grande do Sul. It sits on a peninsula where Lake Patos meets the Atlantic Ocean, just 13 kilometers from the Atlantic estuary. Connected to the inland port of Porto Alegre via an artificial waterway, it forms a " lake - sea intermodal transport " system . Its transportation system covers:

一、里奥格兰德港（Rio Grande）的优势

（一）地理位置与交通网络

里奥格兰德港（Rio Grande）作为巴西南部最重要的海运枢纽之一，是南里奥格兰德州的核心出海口。它坐落在帕图斯湖与大西洋交界处的半岛上，距大西洋入海口仅13公里，通过一条人工航道连接内陆港口阿雷格里港，形成“湖-海联运”体系。其交通体系覆盖：

 Terminal facilities

The port's terminal facilities are strictly zoned by cargo type and incorporate both public and private operations:

Restrictions on vessels over 200 meters: Due to the limited access channel to Lake Patos, oversized vessels must anchor at the outer anchorage and rely on barges for loading and unloading, which increases transit time and costs.

（二）码头设施

里奥格兰德港的码头设施按货类严格分区，兼顾公共与私营运营：

200米以上船舶限制：因帕图斯湖入口航道限制，超长船舶需停泊外锚地，依赖驳船装卸，增加了中转时间和成本

Maritime Services

The service facilities provided by the port include : the port provides storage for refrigerated products and dangerous goods; the port also has a series of basic services such as mooring, small boats, medical care, supplies and repatriation, compulsory pilotage, fresh water supply, fuel filling, captain procurement, crew change coordination, loading and unloading supervision, port fee settlement, spare parts supply, etc .; the port does not have ship repair, refueling, dry dock, and sewage discharge facilities .

（三）海事服务

港口提供的服务设施有：港口提供冷藏品及危险品储存；港口还有系泊、小艇、医疗、给养和遣返、强制引航、淡水补给、燃料加注、船长采购、换员协调、装卸货物监督、港使费结算、备件供应等一系列基础服务；港口无修船、加燃料、干船坞、排污设施。

(四) Hydrological parameters

The port's prevailing winds are northeast and southwest . Using the West Zone 3 standard , unlike most Atlantic ports, Rio Grande's waters have no significant tidal variations, eliminating the need for tidal window calculations . The water density is between 1000 and 1005 m³/t, and the maximum draft is 11.28 meters.

（四）水文参数

港口盛行东北、西南风，采用西3区标准时，区别于多数大西洋港口，里奥格兰德港所在海域无明显潮汐变化，无需计算潮汐窗口。水的载重密度为1000-1005m³/t，最大吃水为11.28米。

China-Pakistan Strategic Cooperation: BRICS Mechanism Drives Port Upgrading

(1) China-Pakistan cooperative relationship

China is an important partner of Brazil. According to data from the United Nations Commodity Trade Statistics Database, Brazil's exports to China exceeded US$94 billion last year.

Green cooperation has become a new engine for synergy between the two countries' port and shipping industries. As the rotating chair of the BRICS in 2025, Brazil is willing to use green cooperation as a link to deepen strategic synergy between Brazil and China, injecting greater development momentum into the "Greater BRICS Cooperation." In recent years, Brazil and China have seen deepening and substantial cooperation in areas such as new energy, infrastructure, and technological innovation. This not only aligns with the development strategies of both countries, but also responds to the expectations of the global South for sustainable development and green transformation.

二、中巴战略合作：金砖机制驱动港口升级

（一）中巴合作关系

中国作为巴西重要的合作伙伴，根据联合国商品贸易统计数据库的数据，去年巴西对华出口额超过940亿美元。

绿色合作成为两国港航业联动的新引擎：作为2025年金砖国家轮值主席国，巴方愿以绿色合作为纽带，深化巴中战略对接，为“大金砖合作”注入更强发展动能。近年来，巴中两国在新能源、基础设施、技术创新等领域的合作不断走深走实，这既契合两国发展战略，也回应了全球南方国家对可持续发展与绿色转型的期待。

(II) Analysis of China-Pakistan Commodity Trade

The Port of Rio Grande is the third largest soybean exporting port in Brazil. It mainly exports soybeans, grains, vegetable oils, fertilizers, etc., among which soybeans are the main product.

According to the People's Daily, Brazil exported about 10.62 million tons of soybeans to China in June, accounting for 86.6% of China's total soybean imports that month, an increase of 9.2% year-on-year.

Brazil's soybean exports to China in 2025

Currently, logistics pressure is a major challenge for Brazilian soybean exports. According to the Brazilian website Agronews, shipping capacity constraints and soaring freight rates at ports in southeastern and southern Brazil have impacted grain transportation efficiency. Chinese shipowners can ship soybeans to the port of Rio Grande, avoiding empty return voyages.

（二）中巴商品贸易分析

里奥格兰德港为巴西第三大大豆出口港，主要出口大豆、谷物、植物油、化肥等，其中大豆为主导。

其中根据人民日报报道，巴西在6月对华大豆出口量约为1062万吨，占中国当月大豆进口总量的86.6%，同比增长9.2%。

2025年巴西对华大豆出口

目前，物流压力是巴西大豆出口面临的一大挑战。巴西《农业新闻》网站称，巴西东南部和南部港口运力紧张，运费飙升，影响了粮食运输效率，中国船东到达里奥格兰德港后，可运送大豆避免空船返航。Port Operations: Sharing Key Information

Key operational information for Chinese shipowners in Rio Grande Port:

1. Crew changes require advance submission of the crew member's passport and SID information. An OKTB letter will be issued to all applicants . The port only permits crew changes at inland anchorages , requiring crew members to embark and disembark at the Rio Grande River anchorage . Crew changes can be handled through a third-party platform, or you can contact the port through the platform for detailed crew change information.
2. If a vessel does not have a fixed sailing schedule at Rio Grande, it will need to pay port opening fees, customs clearance, pilotage, and other related fees before entering the inner anchorage . Shipowners can consult Rio Grande Port information and receive comprehensive service support through third-party platforms.
3. Please note that vessels flying the Chinese flag (which can be extended to China's autonomous regions and administrative regions) will not be fined for having Chinese crew members on board, but even so, they cannot board or disembark unless they hold a valid Brazilian visa.

三、港口实操：关键信息共享

中国船东在里奥格兰德港需要注意实操关键信息：

1.如需更换船员，需要提前提供船员护照和SID信息。对于加入者，将发出OKTB信函。港口对于船员更换只允许在内河锚地进行，船员需要在里奥格兰德河内锚地上下船。换员业务可通过委托第三方平台完成，也可以通过第三方平台咨询港口关于换员的详细信息。

2.如果船只在里奥格兰德没有固定的船期，则需要开港、办理清关、引航及其他相关费用，才能将船只驶入内锚地。船东可通过第三方平台咨询里奥格兰德港的相关信息并获得全方位服务支持。

3.请注意，悬挂中国国旗（可扩展至中国自治区和行政区）的船只不会因船上有中国船员而被罚款，但即使如此，除非他们持有有效的巴西签证，否则不能上船或下船。

Chinese Shipowners: Wind and Waves and Rudder Adjustment During Navigation

(1) Fuel supply

In 2021, a well-known Brazilian oil company stopped supplying VLSFO due to VLSFO pollution, barge refueling was interrupted, and ship endurance was hindered.

Recommendation: Shipowners can complete fuel refueling services through third-party platforms and other channels. In case of emergencies, the platform can provide shipowners with alternative refueling ports and fuel cost calculations, and re-plan a reasonable route.

(2) River siltation

The influx of silt from the Yakui River into the lake has forced frequent dredging, prolonged waiting times for ships, and caused ships to be stranded at the port, leading to congestion and increased costs.

Suggestion: Third-party platforms provide shipowners with port congestion information to help them understand port conditions in advance and recommend alternative ports and optimal detour routes to reduce expenses and losses.

(3) Geopolitics

The CPG report shows that the US cuts pose a direct threat to the export model of the Rio Grande do Sul industry: 140 jobs are at risk. Under the 50 % tariff, many companies will need to reshape their markets or retreat to the domestic market.

Suggestion: Although the interests of some commodities have been damaged by tariffs, under the China-Pakistan cooperation agreement, more soybeans have switched to RMB settlement for export to China, and the port's bulk berths have been loaded with grain ships bound for Asia overnight.

Advantages of third-party platforms

The E-PORTS platform provides shipowners with comprehensive support services at the Port of Rio Grande. Key services include captain procurement, crew changes, cargo loading and unloading, port fee settlement, and spare parts.

四、中国船东：航行中的风浪与舵向调整

（一）燃料供应

2021年巴西知名石油公司曾因VLSFO污染停供，驳船加注中断，船舶续航受阻。

建议：船东可通过第三方平台等途径完成燃油加注服务，如遇突发情况，平台可为船东提供备选加注港口以及油费测算，并重新规划合理路线。

（二）河道淤积

雅库伊河泥沙入湖迫使频繁疏浚，船舶等待期延长，造成船舶滞港、塞港推高成本。

建议：第三方平台为船东提供塞港信息，帮助船东提前了解港口情况，并为船东推荐备选港口以及最优绕行路线，减少支出与损失

（三）地缘政治

CPG的报道显示：美国的削减对南里奥格兰德州工业的出口模式构成了直接威胁：140个工作岗位处于危险之中。在50%的关税下，许多公司将需要重塑市场或撤退到国内市场。

建议：虽然部分商品利益因为关税受损，但在中巴的合作协议下，更多大豆转向人民币结算出口中国，港口散货泊位彻夜装载发往亚洲的粮船。
