Vietnam Telephone Parts (HS 851779) 2025 September Export: Trend Summary

Key Observations

In September 2025, Vietnam's exports of telephone parts under HS Code 851779 reached a value of $1.77 billion, with volume data not provided for the month. This represents a noticeable decrease from August's peak, indicating a shift in export momentum as the year progresses.

Price and Volume Dynamics

The monthly trend shows exports rising steadily from $1.46 billion in January to a high of $1.96 billion in August, before dropping to $1.77 billion in September. This August peak aligns with typical industry cycles, where telephone parts exports often surge ahead of global smartphone production runs and holiday season stock building, followed by a seasonal cooldown in September as inventory levels normalize. The 9.7% month-over-month decline from August to September reflects this cyclical adjustment rather than a structural downturn, with overall 2025 performance remaining robust through the first three quarters.

External Context and Outlook

The export volatility is partly explained by external policy shifts, particularly the U.S.–Vietnam tariff agreement effective July 2025 [Express Trade Capital], which imposed a 20% duty on Vietnamese-origin goods like telephone parts. This likely accelerated August shipments as exporters rushed to avoid higher costs, contributing to the September dip. Strengthened origin verification procedures (EY Vietnam) may also influence future flows, but no new restrictions emerged in September, suggesting a stabilized outlook amid continued demand for Vietnam telephone parts HS Code 851779 export 2025 September.

Vietnam Telephone Parts (HS 851779) 2025 September Export: HS Code Breakdown

Product Specialization and Concentration

In September 2025, Vietnam's export of Telephone Parts under HS Code 851779 is dominated by sub-code 85177921, which describes communication apparatus parts and holds over 70% of the export value with a unit price of $3.57 per unit, indicating a high-volume, low-cost specialization. An extreme price anomaly is present in sub-code 85177992, with a unit price of $572.97 per unit, which is isolated from the main analysis due to its outlier nature.

Value-Chain Structure and Grade Analysis

The non-anomalous sub-codes fall into two main groups: bulk, low-value parts with unit prices under $20, such as 85177929 and 85177932, and mid-range components like 85177939 at $35.55 per unit. This structure points to a trade primarily in fungible bulk commodities, where products are standardized and compete on cost rather than differentiation, with most exports consisting of basic communication parts.

Strategic Implication and Pricing Power

The heavy reliance on low-price bulk items suggests limited pricing power for Vietnamese exporters, who must prioritize cost control and efficiency in their operations. To mitigate risks, firms could explore shifts toward higher-value segments within this HS code. Furthermore, the U.S.–Vietnam tariff agreement imposes a 20% duty on exports [Expresstradecapital.com], emphasizing the need for strict origin compliance to avoid additional cost pressures in the Vietnam Telephone Parts HS Code 851779 Export market for 2025 September.

Vietnam Telephone Parts (HS 851779) 2025 September Export: Market Concentration

Geographic Concentration and Dominant Role

Vietnam Telephone Parts HS Code 851779 Export 2025 September shows Vietnam as the dominant supplier, accounting for over half (51.15%) of the total export value. However, its share of the total quantity shipped is even higher (69.35%), indicating these parts are relatively lower-value components. The unit price for Vietnam's exports is approximately $3.12 per unit, which is significantly cheaper than South Korea's $8.52 per unit, confirming a focus on cost-effective, high-volume manufacturing.

Partner Countries Clusters and Underlying Causes

The partner countries form three clear clusters. The first is high-value manufacturing hubs like South Korea (13.29% value share) and China/Hong Kong (combined ~14% value share), which likely supply more sophisticated, expensive components. The second is volume-driven markets like India (12.83% quantity share), suggesting demand for large quantities of affordable parts. The third cluster consists of smaller, strategic markets like the US, Brazil, and Taiwan, which represent specialized, lower-volume niches within the global supply chain.

Forward Strategy and Supply Chain Implications

Exporters must prioritize origin verification and compliance, especially for US-bound shipments which now face a 20% tariff under the new agreement [Schulz Law]. The concentration in Vietnam underscores its role as a final assembly hub, but the reliance on higher-value inputs from South Korea and China highlights a strategic vulnerability. Diversifying sources for advanced components and ensuring robust documentation to prove country of origin, as per Vietnam's strengthened procedures [EY Vietnam], is critical for maintaining tariff advantages and mitigating supply chain risk.
