The substantial growth in brass product exports and the widening trade surplus may be due to several factors. First, the increased demand for brass products in the international market may be one of the main reasons for the increase in export volume. Brass products are widely used in construction, electronics, automobiles and other industries, so with the development of these industries, the demand for brass products has also increased accordingly.
Secondly, the quality and competitiveness of brass products may be key factors in attracting international markets. If brass products have advantages in terms of quality and price, then foreign buyers may be more willing to choose to purchase brass products, leading to an increase in export volume.
In addition, government support and policy measures may also play a role in promoting the growth of brass product exports. The government may support the export of brass products by reducing tariffs and providing trade facilitation, thereby expanding the trade surplus.
In general, the substantial growth in brass product exports and the expansion of trade surplus may be due to the combined effects of increased market demand, improved product competitiveness, and government support.
