π’ Architectural Glass (Building & Construction Glass)
π HS Code Reference & Customs Clearance Guide | 2026 Latest Tariff Analysis | Professional Compliance Strategy π I. Product Definition & Classification: Do You Really Understand "Architectural Glass"?
Architectural glass is not just a single product; it is a complex category in international trade. It covers everything from basic window panes to high-tech smart glass and safety laminated glass. Misclassification here is one of the most common causes of customs delays and excessive duties.
In international trade, it is primarily divided into three core categories based on processing level and function:
- Raw/Flat Glass (Unprocessed or Simply Cut): Includes float glass, annealed glass, and basic cut-to-size sheets.
- Processed/Safety Glass (Tempered/Laminated): Includes tempered glass, laminated glass, insulated glass units (IGUs), and coated glass (Low-E).
- Optical/Specialty Glass: Includes high-end optical glass or glass with specific electronic functions (though rare in standard architecture).
β οΈ Key Distinction Point: * If the glass is only cut/edge-grounded but not tempered or laminated β Usually falls under 7007. * If the glass is tempered, laminated, or insulated β Falls under 7008. * If the glass is part of a pre-assembled window frame β Falls under 7010 or 7610 (depending on material), NOT 7007/7008.
π¦ II. HS Code Classification Details (2026 Latest Tariff Authority)
| HS Code | Product Description | Application Scenario | Processing Level |
|---|---|---|---|
7007.11.00.00 |
Tempered glass (heat-strengthened), whether or not cut to shape | Car windshields, Building safety glass, furniture glass | β Tempered |
7007.19.00.00 |
Other safety glass, whether or not cut to shape (e.g., Laminated, Wire glass) | Laminated glass, bulletproof glass, wire mesh glass | β Laminated/Safety |
7008.00.00.00 |
Multi-glazed insulating glass units | Insulated Glass Units (IGU) for windows/doors, Double/Glazed glass | β Assembled Unit |
7009.92.00.00 |
Mirrors with backing, other than of glass of heading 70.06 | Architectural mirrors, decorative wall mirrors | β Mirrors |
7020.00.98.00 |
Other articles of glass | Glass knobs, handles, decorative glass art, glass beads | β Non-structural |
7610.10.00.00 |
Aluminum structures and parts thereof (if pre-assembled) | Aluminum window frames with glass installed (Frame + Glass as one unit) | β Composite Product |
π Critical Reminder: * Laminated Glass (two or more panes bonded with PVB/SGP interlayer) is classified as Safety Glass under
7007.19.00.00, not raw glass. * Insulated Glass Units (IGUs) (double/triple glazed with spacer) are classified under7008.00.00.00. This is a separate category from single panes. * If the glass is sold already installed in a window frame, it may be classified as a building component (e.g., Aluminum structures7610) or windows depending on local customs rules, often leading to different duty rates.

7009.91.00.00), though duties are similar.
π οΈ IV. Customs Clearance Practical Advice (Real-World Pitfall Guide)
β 1. Documentation Checklist (Missing Any = Delay/Return)
| Document | Mandatory? | Description |
|---|---|---|
| β Product Specification Sheet | βοΈ | Must specify: Thickness, Type (Tempered/Laminated/IGU), Dimensions, Coating (Low-E), Certification Standard (ASTM/EN). |
| β Manufacturing Process Flow | βοΈ | Crucial to prove if it is "Tempered" or "Laminated". Customs needs to verify safety glass status. |
| β Commercial Invoice | βοΈ | Must clearly state: "Tempered Safety Glass" or "Insulating Glass Unit". Do NOT just write "Glass". |
| β Packing List | βοΈ | Detail packaging: Crates, edge protectors, pallets. Glass is fragile; proper packaging proof may be requested. |
| β Bill of Lading / Air Waybill | βοΈ | Standard shipping documents. |
| β Certificate of Origin (CO) | βοΈ | If applicable for other countries; for US, origin is critical for 301/IEEPA applicability. |
| β Safety Certifications | βοΈ | CPSC, CGA, or ASTM standards compliance certificates. |
β 2. Declaration Skills (Key Mantra)
π₯ βGlass Type Clear, Process Exact, Frame vs Sheet, Duty Gap Huge!β
| Situation | Correct Declaration | Wrong Practice |
|---|---|---|
| Single Pane, Tempered | 7007.11.00.00 - "Tempered Safety Glass, Heat-Strengthened" |
Misdeclare as "Flat Glass" β Risk of Anti-Dumping investigation |
| Double Glazed (IGU) | 7008.00.00.00 - "Insulating Glass Unit, Double Glazed" |
Misdeclare as "Two separate sheets of glass" β Incorrect valuation |
| Laminated Glass | 7007.19.00.00 - "Laminated Safety Glass" |
Misdeclare as "Tempered Glass" β Inaccurate data, potential penalties |
| Glass in Aluminum Frame | 7610.10.00.00 - "Aluminum Window Frame with Glass" |
Misdeclare as "Glass" β May face different duty rates (check HTSUS 7610 vs 7007) |
| Decorative Glass Art | 7020.00.98.00 |
Misdeclare as "Architectural Glass" β Unnecessary high duties if art classification applies |
β 3. Special Case Handling
| Situation | Handling Advice |
|---|---|
| OEM Custom Sizes | Provide precise dimensions and cutting templates. Ensure invoices reflect the custom nature to avoid valuation disputes. |
| Low-E Coated Glass | Explicitly state "Low-E Coated" in the description. Some buyers may seek exemptions, but generally, it follows standard safety glass duties. |
| Glass for Curtain Walls | If sold as a system (glass + aluminum + seals), consider classifying as a building component (7610 or 7318). This might offer a lower duty rate than glass alone. |
| Small Samples | If value is very low, ensure it qualifies for de minimis, but be aware that glass samples are rarely exempt due to anti-dumping laws. |
π V. Global Main Market Customs Comparison (2026 Latest)
| Country/Region | Recommended HS Code | Duty Rate (China Origin) | Certification Requirements | Notes |
|---|---|---|---|---|
| πΊπΈ USA | 7007.11.00.00 |
41.5% | ASTM, CGA, CPSC | Highest burden due to 301 + IEEPA |
| π¨π³ China | 7007.11.00.00 |
0% (for domestic trade) | CCC (if applicable) | Low import duty, high local production |
| πͺπΊ EU | 7007.11.00.00 |
6.5% (MFN) | CE, EN 12150, EN 12600 | No 301 equivalent, but strict safety standards |
| π¬π§ UK | 7007.11.00.00 |
0% (if UK-China FTA applies*) | UKCA | Check latest post-Brexit trade agreements |
| π¦πΊ Australia | 7007.11.00.00 |
5% | SAA | Moderate duty |
π Conclusion: * USA is the most challenging market for architectural glass due to the combined 41.5% duty rate. * EU and UK offer more favorable rates but enforce strict safety and environmental standards (CE, Low-E energy ratings). * Strategy: For the US market, consider supply chain diversification (e.g., sourcing from Vietnam or Mexico if possible) to avoid 301/IEEPA tariffs.
π VI. Common Errors & Pitfall Guide (Lessons Learned)
β Error 1: Declaring "Tempered Glass" but providing only "Annealed Glass" specifications. π Consequence: Customs inspection reveals no tempering treatment β Misclassification, fines, and possible seizure.
β Error 2: Mixing "Single Glazed" and "Insulated Units" in one shipment without clear breakdown. π Consequence: Valuation errors β Customs will reassess and charge higher duties on the entire shipment.
β Error 3: Not specifying "Safety Glass" in the invoice.
π Consequence: Customs may classify as raw glass (7007.90), triggering anti-dumping duties which can exceed 100%.
β Error 4: Declaring "Glass Frames" as "Glass".
π Consequence: If it's an aluminum frame with glass, it should be 7610. Misdeclaration leads to incorrect duty application.
β Correct Approach:
"10mm Tempered Laminated Safety Glass, Low-E Coated, Cut to Size 1200x2400mm, ASTM C1048 Compliant, For Architectural Curtain Wall, Made in China."
π― VII. Conclusion: Precision in Classification Saves Money!
π― Remember the Mantra:
πΉ "Tempered is 7007.11, Laminated is 7007.19, Insulated is 7008. Don't mix them up!" πΉ "US Tariff is 41.5%, Origin Matters, Documentation is Key." πΉ "Glass in Frame? Think 7610. Glass Alone? Think 7007/7008."
π Pro Tip:
If your architectural glass is originally sourced from countries not subject to Section 301 or IEEPA (e.g., Vietnam, Thailand, or US domestic), you can significantly reduce costs. Recommendation: Request an Advance Ruling (Ruling Letter) from CBP before shipping high-value batches to ensure your HS Code and duty calculation are locked in.
π£ Immediate Action:
π Contact a licensed customs broker + Provide product datasheets + Verify HTSUS codes π Ensure your architectural glass clears customs smoothly, avoids penalties, and protects your margins!
β¨ Professional Customs Clearance Starts with Precise Classification! πΌ Every percentage point of duty saved is pure profit!

About HS Code Classification
The Harmonized System (HS) is an internationally standardized nomenclature developed by the World Customs Organization (WCO) to classify traded products. Over 200 countries use the HS system as the basis for customs tariffs, trade statistics, and import/export regulations.
Each HS code follows a hierarchical structure:
- Chapter (2 digits) β Broad category of goods (e.g., Chapter 84: Machinery and Mechanical Appliances)
- Heading (4 digits) β More specific grouping within the chapter
- Subheading (6 digits) β Internationally standardized breakdown, used by all WCO member countries
- National subdivisions (8-10 digits) β Country-specific extensions for further classification, such as US HTSUS 10-digit codes
Correct HS code classification is essential for smooth customs clearance, accurate duty payment, and compliance with trade regulations. Misclassification can lead to customs delays, overpayment of duties, or penalties.
When importing from CN to US, the applicable tariff rates may include:
- Most-Favored-Nation (MFN) rate β The standard duty rate applied to WTO members
- General rate β Applied to countries without trade agreements
- Trade remedy duties β Additional tariffs such as Section 301 (anti-dumping), Section 232 (national security), or countervailing duties
