I. China’s Export Side: Zero Tariffs and 13% Tax Rebates
The tax burden on the Chinese side of fastener exports is low (based on customs export policies). Export Tariffs: Export tariffs for fasteners (HS Code 7318: bolts, nuts, screws, etc.) are essentially zero; China encourages manufacturing exports, and most industrial goods are subject to zero export tariffs.
Export Tax Rebates: Fasteners qualify for a 13% VAT export rebate.
Obtaining this rebate—part of the export profit—requires proper customs declaration (ensuring the declared product name matches the HS code) and the acquisition of necessary documentation (customs declaration forms and VAT invoices).
Key considerations for the Chinese export stage include: accurate HS code classification (e.g., bolts 7318.15, nuts 7318.16, washers 7318.22)—as incorrect classification affects both rebates and the tax rates applied by the destination country—and consistent declaration of material composition (carbon steel and stainless steel fall under different HS subheadings).
Conclusion for the Chinese export stage: The combination of zero tariffs and a 13% tax rebate acts as a “trade surplus dividend,” meaning export costs are driven primarily by raw materials and processing rather than taxation.
II.
US Import Side: Base Duty + Section 301 Tariffs
US tariffs on imported fasteners consist of two components (based on HTS codes and publicly available US trade policy information).
Base Duty Rate: The MFN (Most-Favored-Nation) base duty rate for iron/steel bolts, screws, and nuts under HTS heading 7318 is approximately 3.4% (though some categories, such as square-head screws, are subject to a 12.5% rate).
Additional Tariffs: Section 301 tariffs (effective July 24, 2026, the rate shifts from a flat 10% to a two-tiered structure of 10% or 12.5%)—the combined tariff rate for fasteners (made in China) ranges from approximately 13.4% to 15.9%; additional measures on steel products (a 25% tariff on steel products and derivatives, including items like nails, was announced for 2025).
Calculation method: Tariff = (CIF value) × tax rate—cargo value is calculated based on the CIF price (including freight and insurance); payable by the importer (US buyer) and factored into DDP quotations.
Strategies for the US market: Quote the full DDP price (including tariffs), absorb tariff costs through high-value-added products, and monitor changes to the Section 301 exclusion list—tariff structures for the US route are evolving;
verify the latest rates before quoting.
III. EU Import Side: Heaviest Anti-Dumping Duties
The EU imposes the heaviest tariff burden on fasteners (according to announcements by the Ministry of Commerce and the European Commission).
Anti-dumping duties on steel fasteners: Since February 18, 2022, the EU has imposed definitive anti-dumping duties on steel fasteners originating from China—most companies face a rate of 86.5% of the net price at the EU border (pre-tax), while specific rates for some companies range from 22.1% to 48.8% (anti-dumping measures are set to expire in June 2026; monitor the results of the expiry review).
Headless screws (threaded rods): In October 2025, the EU issued a final ruling imposing anti-dumping duties ranging from 54.7% to 72.3% (CN codes 7318 15 42/48; market value approximately €500 million).
Calculation method: Anti-dumping duties are calculated based on the CIF (Cost, Insurance, and Freight) price at the EU border; the total tax burden equals the base tariff plus the anti-dumping duty. The total tax burden on Chinese fasteners exported to the EU can range from 60% to 100%.
EU response strategies include: applying for individual duty rates (cooperating with investigations to secure the lower 22.1% tier), strategic re-routing/transshipment (utilizing production capacity in Southeast Asia), focusing on high-value-added products (to avoid anti-dumping measures targeting low-end goods), and monitoring expiry reviews of measures.
IV.
Other Markets and Practical Calculation
Tariff levels in other major markets (based on publicly available rate data): Southeast Asia (ASEAN)—base fastener tariffs of 0% to 5% (with some at zero)—representing the lowest-cost market.
Middle East (GCC countries)—base tariffs of approximately 5%. Africa—mostly 5% to 20% (varying by country).
South America (e.g., Brazil)—10% to 20% (characterized by strong trade protectionism).
UK—base tariffs of approximately 2.7% plus anti-dumping measures (following independent assessment after mirroring EU measures).
Practical calculation involves three steps: first, identify the HS Code (HS 7318 subheadings based on material and product category); second, check the destination country’s base tariff rate and any special measures (anti-dumping, Section 301, Section 232); third, calculate the tariff as (CIF value) × total tax rate, and determine the DDP quote as (Goods Value + Ocean Freight + Tariffs + Customs Clearance & Delivery Fees).
Practical tip: Tariff policies change quarterly (due to Section 301 adjustments or anti-dumping reviews), so verify the latest rates before quoting (using the US HTS website, EU TARIC, or Ministry of Commerce alerts)—rates applicable at the time of the quote are the ones that count.
V.
Tariff Optimization and Compliance Recommendations
Five recommendations for tariff optimization and compliance.
1. Market Mix: Prioritize increasing volume in Southeast Asia and the Middle East due to low tariffs (0–5%); assess the impact of anti-dumping measures in the EU (shift to high-value-added products to mitigate high rates); and quote based on Section 301 tariff rates for the US market.
2. Accurate HS Classification: Ensure correct classification of material (carbon steel/stainless steel) and product type (bolts/screws/nuts) to avoid errors in both tariff rates and tax rebates.
3. Rules of Origin Compliance: For transshipment (e.g., via Southeast Asia), adhere to rules of origin (specifically “substantial transformation” requirements)—avoid “gray area” channels, as tax avoidance via transshipment carries compliance risks.
4. Transparent Quotations: Itemize tariff components in DDP quotes (improves customer acceptance and ensures transparency in customs clearance).
5. Policy Monitoring: Track anti-dumping reviews, Section 301 exemptions, and tariff adjustments—monitor Ministry of Commerce and Customs alerts on a quarterly basis.
Understanding Fastener Tariffs: 0% export tariff plus a 13% tax rebate in China (favorable); 13%–25% for the US market (manageable); and 60%–100% anti-dumping duties for the EU (most severe)—the tariff burden can be controlled through strategic market selection and a focus on high-value-added products.
Conclusion
How are export tariffs for industrial fasteners calculated?
In China, the export tariff is 0% with a 13% tax rebate;
for the US, the rate comprises a base of ~3.4% plus Section 301 tariffs (totaling ~13.4%–15.9%, or 25% for some items); and for the EU, anti-dumping duties range from 22.1% to 86.5% (54.7%–72.3% for headless screws). Tariff = (CIF Price) × Tax Rate.
By ensuring accurate HS classification, optimizing market mix, and monitoring policies quarterly, fastener export tariffs can be clearly calculated and effectively managed.
