Securing ABS and LR certificates for your bulb flat steel shipment is just the beginning. I’ve seen shipments get held up at customs because of incorrect HS codes, turning a successful certification process into a logistical nightmare. Getting the documentation right is as important as the steel quality itself.

To export bulb flat steel with ABS/LR certificates successfully, you need correct HS code classification (typically 7216.10 for hot-rolled), complete certification documents from the classification societies, accurate commercial invoices with HSN codes for the destination country, and proper packaging markings that match all documentation. Each element must align perfectly to ensure smooth customs clearance.

From my experience working with clients from Saudi Arabia to the Philippines, I’ve learned that the certification is only half the battle. The real test comes when the paperwork meets customs regulations. Let me share the practical insights I’ve gained about navigating this complex process successfully.

What is the HS code for bulb flat steel?

A shipment to Vietnam was delayed for five days because the freight forwarder used a generic steel code instead of the specific code for bulb flats¹. The importer faced demurrage charges that erased their cost savings. This taught me that precision in HS coding is non-negotiable.

The HS code for hot-rolled bulb flat steel² is generally 7216.10³.90 under the Harmonized System. This falls under heading 7216 for "Angles, shapes and sections of iron or non-alloy steel, not further worked than hot-rolled," with the final digits varying by country to specify "other" sections like bulb flats¹. However, the exact code can differ based on dimensions and alloy content, so verification with local customs is essential.

Navigating HS Code Classification for Specialized Steel Profiles

Based on my dealings with customs brokers⁴ across different countries, I’ve found that bulb flats¹ present specific classification challenges that require careful attention.

Understanding the 7216 Category
The HS system follows a logical hierarchy:

• Chapter 72: Iron and steel
• Heading 7216: Angles, shapes and sections of iron or non-alloy steel
• Subheading 7216.10³: Not further worked than hot-rolled, hot-drawn or extruded
• Further digits: Country-specific breakdowns, often .90 for "other" shapes

Key Factors That Affect Classification

1. Manufacturing Process:

   • Hot-rolled bulb flats¹: 7216.10³
   • Cold-formed bulb flats¹: Likely 7216.50 ("Other")
   • This distinction matters because the process affects material properties

2. Material Composition:

   • Non-alloy steel (carbon steel): 7216.10³
   • Alloy steel: May shift to 7228 series
   • Most marine bulb flats⁵s](http://www.ozkansteel.com/en/details/shipbuilding-oil-gas-profiles/bulb-flats-199)[^1] are carbon steel, so 7216.10³ usually applies

3. Dimensions and Specifications:

   • Some countries have specific codes for particular size ranges
   • Large or specialized sections might have different classifications

Common Classification Scenarios

Bulb Flat Description	Likely HS Code	Important Considerations
Hot-rolled, carbon steel, standard sizes	7216.103.90	Most common for marine applications
ABS/LR certified marine grade	Same 7216.103.90	Certification doesn’t change HS code
Over 80mm in height	Check local variations	Some countries have size-based classifications
Galvanized or coated	Usually same base code	Coating must be declared separately

Practical Export Advice from Experience

1. Always verify with the destination: Customs rules vary. What works for Saudi Arabia may not work for India
2. Use detailed descriptions: "Hot-rolled bulb flat steel for shipbuilding, 250x12mm" is better than just "steel sections"
3. Keep documentation consistent: The HS code on the commercial invoice must match the packing list and bill of lading
4. Work with experienced forwarders: Those familiar with steel exports understand these nuances

I recall a shipment to Mexico where the local customs required additional documentation because the bulb flats¹ were classified as "special profiles." Having an experienced forwarder who anticipated this saved two days of processing time.

What is the HS code for flat steel?

A client in Qatar once received a shipment where flat steel plates and bulb flats¹ shared the same HS code on documents. Customs flagged this as inconsistent since these are different products with potentially different duty rates². Proper classification prevents such issues.

Flat steel typically falls under HS code 7208³ for hot-rolled flat products or 7210 for coated/flat-rolled products. However, bulb flats¹ are not "flat steel" in the HS system—they’re classified as "sections" under 7216. The distinction is crucial because flat products (plates, sheets) and sections (angles, beams, bulb flats¹) have different tariff rates and regulatory requirements in many countries. Using the wrong category can lead to customs delays and incorrect duty assessments.

Understanding the Critical Distinction Between Flat Products and Sections

Through years of export documentation preparation, I’ve learned that this classification difference has significant practical implications.

Flat Steel Products Defined
In HS terminology, "flat steel" refers to:

• Plates
• Sheets
• Strips
• Coils
  These are classified mainly under:
• 7208: Hot-rolled flat products
• 7210: Coated/flat-rolled products
• 7212: Cold-rolled flat products

Bulb Flats as "Sections"
Bulb flats belong to a different category because:

1. They have a specific cross-sectional shape
2. They’re designed as structural members, not as plating material
3. Their manufacturing process creates a defined profile

Why the Distinction Matters in Practice

1. Duty Rates: Many countries have different tariff rates for flat products versus sections
2. Import Restrictions: Some countries have quotas or licenses specific to product categories
3. Technical Standards: Certification requirements differ between structural sections and plating materials
4. Shipping Requirements: Handling and stowage considerations vary

Common Classification Errors I’ve Encountered

Incorrect Classification	Correct Classification	Problem Created
Bulb flats as 7208.51 (flat plates)	7216.10 (sections)	Wrong duty calculation, potential penalties
Flat bars as 7216.10	7214.10 (bars)	Customs questioning, documentation review
Universal "steel" code	Product-specific code	Higher duty rate or import restrictions4

Documentation Best Practices
From handling hundreds of shipments:

1. Be specific in descriptions: "Bulb flat steel sections, hot-rolled" not just "steel"
2. Match all documents: Commercial invoice, packing list, and bill of lading should use identical descriptions
3. Include supplementary details: Adding "for shipbuilding" or "structural sections" helps customs officers
4. Maintain consistency: Once established for a client, use the same classification for repeat orders

A Real-World Example
A shipment to the Philippines contained both steel plates (7208.51) and bulb flats¹ (7216.10). By clearly separating these in the documentation with proper quantities and values for each code, the importer avoided the higher duty rate that would have applied if everything was classified under the plate code. This attention to detail saved them approximately 7% in total landed cost.

What is the GST rate¹ on bulbs?

When a client in India asked about importing bulb flats, they were surprised to learn that "bulbs" in customs terminology could mean lighting products. This confusion nearly led to incorrect GST calculations until we clarified the specific product classification.

For bulb flat steel² imports into India, the applicable GST rate¹ is 18%, as it falls under general steel products classification. However, "bulbs" for lighting fixtures have a different GST rate¹ of 12-28% depending on type, highlighting the importance of precise product description in customs declaration³s to avoid classification errors and incorrect tax assessments. Using clear terminology like "steel bulb flats for shipbuilding" prevents confusion with electrical bulbs.

Navigating Tax Implications for Steel Products vs. Other "Bulbs"

Based on my experience with Indian imports, I’ve learned that terminology matters significantly in tax calculations.

GST Structure for Steel Products
India’s GST system categorizes steel products under Chapter 72-73:

• Most steel products: 18% GST rate¹
• Specified steel items: May have different rates
• Bulb flats specifically: Typically 18% as structural steel sections

Common Classification Confusions
The term "bulb" creates several potential misunderstandings:

Product Type	HS Code Range	GST Rate	Common Confusion Point
Bulb flat steel	7216.10	18%	Mistaken for electrical goods
Light bulbs	8539	12-28%	Different category entirely
Bulb angles	7216.10	18%	Similar to bulb flats
Special bulbs	Various	Varies	Depends on exact product

Documentation Requirements for Clarity
To ensure correct GST assessment:

1. Use full product names: "Hot-rolled bulb flat steel² sections"
2. Include application: "For marine/shipbuilding use"
3. Reference standards: "JIS G3192 bulb flats"
4. Provide dimensions: "Size: 250mm x 12mm"

Import Process Considerations for India
From working with Indian clients:

1. IGST applies⁴: Integrated GST is levied on imports
2. Customs value basis: GST calculated on CIF value plus basic customs duty
3. Input tax credit: Importers can claim credit for IGST paid
4. Documentation needs: Commercial invoice, packing list, bill of lading, and MTC must all align

Practical Example from Recent Shipments
A shipment to Mumbai contained:

• Bulb flats: 18% GST under 7216.10
• Marine plates: 18% GST under 7208.51
• Total IGST payable: Based on CIF value of $85,000 + 7.5% basic customs duty

By having clear documentation specifying "steel bulb flats" rather than just "bulbs," the importer avoided a potential reclassification that could have triggered a 28% rate for "electrical apparatus." This saved approximately $8,500 in potential additional tax liability.

Are HSN codes¹ required for exports?

When exporting to Saudi Arabia, our client was confused about whether they needed HSN codes¹ since India uses them for domestic GST. This highlights a common misunderstanding—HSN codes¹ are for Indian systems, while exports use the international HS code system² with country-specific adaptations.

HSN (Harmonized System of Nomenclature) codes are primarily required for goods and services within India’s GST system. For exports from China, international HS codes are used on shipping documents. However, if your buyer is in India or another country using HSN-based systems, they will need the appropriate HSN code for their import declaration³ and GST compliance⁴. As an exporter, you provide the HS code; importers handle HSN requirements for their local tax systems.

Understanding the Role of HSN in International Trade

From coordinating with importers in various countries, I’ve developed a clear understanding of how HSN fits into the global trade documentation chain.

HSN vs. HS: The Fundamental Difference

• HS Codes: International standard, 6-digit base
• HSN Codes: India’s extension to 8 digits for GST purposes
• Other systems: Different countries have their own extensions (e.g., Philippines uses 10-digit codes)

Documentation Flow in Practice
Here’s how the coding works in actual shipments:

Document	Coding System Used	Purpose	Responsibility
Commercial Invoice	HS Code (6-10 digit)	International customs clearance	Exporter (China)
Bill of Lading	HS Code	Shipping documentation	Carrier/Freight forwarder
Import Declaration	HSN Code (8 digit for India)	Local tax assessment	Importer (Destination country)
GST Filing	HSN Code	Tax compliance	Importer

Common Scenarios I’ve Encountered

Scenario 1: Exporting to India

• We provide: HS code 7216.10.90 on all export documents
• Indian importer converts to: HSN code 7216.10.90 (same digits for this product)
• They use this for: Customs clearance and GST credit claims

Scenario 2: Exporting to UAE

• We provide: HS code 7216.10
• UAE uses: Same HS system, may add local digits
• Documentation: Simpler, as VAT system differs from India’s GST

Scenario 3: Mixed Destinations

• Same bulb flats to different countries
• Same HS code from our side
• Different local coding requirements at destination

Best Practices for Exporters
Based on my experience:

1. Always use correct HS codes: This is your responsibility as exporter
2. Understand destination requirements: Some countries need additional detail
3. Maintain consistency: Use the same code for the same product to all destinations
4. Document your decisions: Keep records of why you chose specific codes
5. Update knowledge: HS system updates every 5 years (2022, 2027, etc.)

A Helpful Reference Table

Country	System Used	Digits Required	Notes from Experience
India	HSN	8 digits	Must align with GST rate schedules
Saudi Arabia	HS with local mods	10 digits	Part of GCC unified system
Philippines	AHTN	10 digits	ASEAN Harmonized Tariff Nomenclature
Vietnam	HS-based	8 digits	Similar to but not identical to India
Mexico	HS-based	10 digits	Número de identificación comercial

Key Insight from Practice
The most important thing I’ve learned is that while we control the export documentation⁵, we need to educate our buyers about their import documentation requirements. When Gulf Metal Solutions first ordered from us, we provided not just the HS code but also explained how it would be used in Saudi Arabia’s customs system. This proactive communication prevented documentation issues and built trust from the very first shipment.

Conclusion

Successfully exporting certified bulb flat steel requires precise HS code classification, understanding distinctions between product categories, awareness of destination tax systems, and clear documentation that bridges international standards with local requirements like HSN codes.
