What Top Automotive Importers Declare Under HS Code 731815 (Bolts, Screws & Stainless Steel Fasteners)
In global trade, HS Code 731815 represents one of the most frequently used categories for threaded fasteners. But behind that six‑digit number lies a complex landscape of material grades, product descriptions, and real‑world customs declarations that can make or break a shipment’s compliance. At TradeMagellan, our supply chain intelligence team has analyzed millions of customs records to reveal exactly how industry leaders are classifying their bolts, screws, and stainless steel fasteners under this code – and what that means for your own trade operations.
What Is HS Code 731815?
HS Code 731815 is defined by the World Customs Organization as “other screws and bolts, whether or not with their nuts or washers.” It covers a broad range of threaded articles made of iron or steel, typically used to mechanically join two or more components. The heading itself does not differentiate by strength class, coating, or exact alloy composition; it is the commercial description on the customs declaration that often provides the critical nuance.
In practice, this means a single HS Code can encompass everything from a standard carbon‑steel hex bolt to a high‑end stainless steel fastener destined for an automotive assembly line. Understanding how major buyers apply this code is essential for suppliers and logistics providers aiming to avoid costly misclassification.
How Automotive Giants Actually Declare Under 731815
TradeMagellan’s proprietary customs data model gives us visibility into the exact product descriptions filed by some of the world’s largest importers. When we examine shipments linked to HS Code 731815, a clear pattern emerges: leading automotive and industrial fastener companies consistently use specific, material‑focused language that goes far beyond a simple “bolt” or “screw.”
- STELFAST INC. – BOLT
- VOLKSWAGEN DE MEXICO S.A. DE C.V. – SCREW
- INDIANA AUTOMOTIVE FASTENERS INC. – SS FASTNER OTHER SCREWS AND BOLTS,WHETHER OR NOT WITH THEIR NUTS OR BOLTS( GRADE 1.4404A )
- SPAN DE MEXICO S.A. DE C.V. – SCREW
- VELIM S.A. DE C.V. – BOLT
The most instructive example is INDIANA AUTOMOTIVE FASTENERS INC., which explicitly describes its merchandise as “SS FASTNER OTHER SCREWS AND BOLTS,WHETHER OR NOT WITH THEIR NUTS OR BOLTS( GRADE 1.4404A )” – a direct reference to the product category plus the specific stainless steel grade (1.4404A, equivalent to 316L). This level of granularity helps customs authorities identify the true nature of the goods, reducing the chance of a query or secondary inspection.
Meanwhile, VOLKSWAGEN DE MEXICO S.A. DE C.V., a subsidiary of the German automotive group, consistently uses the straightforward term “SCREW” for its imports under this code – a choice that aligns with its just-in-time manufacturing environment, where part numbers and engineering specifications are managed separately from the HS declaration. Other companies like STELFAST and VELIM file with the minimal term “BOLT,” demonstrating that even simple descriptions can be accepted when backed by a robust compliance history.
Why Benchmarking Against Industry Leaders Reduces Misclassification Risk
Customs misclassification is not a theoretical risk. It can lead to delayed shipments, retrospective duty demands, and even penalties. By studying how top‑tier importers handle HS Code 731815, traders can align their own documentation practices with what customs authorities routinely accept. This is not about copying a competitor; it is about understanding the market standard for product description adequacy.
Key takeaway: A product description that includes critical details – such as “stainless steel grade 1.4404A” or “SS FASTNER … with its nuts” – makes the item easily identifiable under 731815, while a laconic “BOLT” may still pass but leaves less room for error during an audit.
For companies importing or exporting fasteners, the strategic question is not whether HS Code 731815 is correct, but whether the accompanying commercial description will withstand scrutiny. TradeMagellan’s data shows that the most consistent, penalty‑free shipments are those where the description bridges the gap between a generic harmonized code and the specific engineering reality of the product. By referencing the approaches of VOLKSWAGEN DE MEXICO, INDIANA AUTOMOTIVE FASTENERS, and others, you can build a more defensible customs declaration – without reinventing the wheel.
How TradeMagellan Enables Smarter HS Code Decisions
Our platform goes beyond static classification tables; it surfaces the actual language used by millions of shipments worldwide. Whether you are shipping simple carbon‑steel bolts or complex stainless‑steel screw assemblies, you can instantly see which HS Codes your competitors and customers are assigning, along with the exact product descriptions they trust. This intelligence helps you:
- Audit your current HS codes against real trade benchmarks.
- Identify when a more detailed description (e.g., including material grade) is warranted.
- Monitor classification trends across key automotive and industrial buyers like those shown above.
In a regulatory environment where an incorrect classification can cost 5% to 15% of the shipment value in additional duties and fees, having a data‑backed approach is not optional – it is the new standard of due diligence.
TradeMagellan’s supply chain analysts continuously monitor customs data across more than 90 countries. This article draws on real transactional records to help trade professionals navigate HS classification with confidence. For deeper insights or to explore our data, contact our team.
