Duty Calculation Tips for HTS 700521
Glass containers (7010) and table/kitchen glassware (7013) are the high-volume consumer imports, with general rates typically in the 5%–6% range depending on whether they are lead crystal or other glass, and whether they are valued above or below a per-piece threshold. Glassware from China is subject to Section 301 List 4A (7.5%) tariffs, and certain glass containers and tableware have a history of US anti-dumping cases. For large glass container imports, the value-per-unit threshold inside 7010/7013 subheadings can materially change the rate.
Chapter 70 Frequently Asked Questions
Are glass drinking glasses classified in Chapter 70?
Yes, glassware of a kind used for table or kitchen purposes is classified in heading 7013. Whether it is lead crystal or other glass, and its value per piece, determines the precise subheading and duty rate.
Is tableware of glass classified with ceramic tableware?
No. Glass tableware is in Chapter 70 (heading 7013), while ceramic tableware is in Chapter 69. The material — vitreous glass vs. fired clay/ceramic — determines the chapter.
Do Chinese glass products face anti-dumping duties?
Several categories of Chinese-origin glass products have been subject to US anti-dumping and countervailing duty orders, including certain glass containers and tableware. Verify the current ADD/CVD scope in addition to Section 301 tariffs.
Where are mirrors classified?
Glass mirrors, whether framed or not, are classified in heading 7009 of Chapter 70, unless they are specially designed optical mirrors of Chapter 90 or automotive rear-view mirrors that are part of a vehicle (classified with the vehicle).
What is the difference between Chapter 70 glass and Chapter 69 ceramic?
Glass is produced by vitrification of silica and is classified in Chapter 70, whereas ceramic articles are made by firing clay and non-metallic minerals and are classified in Chapter 69. The two chapters are mutually exclusive based on material and manufacturing process.
What Importers Need to Know About HTS Chapter 70
This subheading falls under an HTS chapter covering products classified under this heading of the Harmonized Tariff Schedule. Importers of these products should be aware of the following trade compliance considerations:
Importers should verify classification with CBP or a licensed customs broker. Check whether Section 301, Section 232, or anti-dumping/countervailing duties apply to your product based on country of origin and specific HTS classification.
For the specific subheading HTS 700521, we recommend you:
- Verify the correct 10-digit statistical suffix — even within a 6-digit subheading, duty rates can differ significantly between suffixes
- Check FTA eligibility — if your product qualifies for preferential treatment under USMCA, KORUS, or another FTA, you may reduce or eliminate duties by providing the required origin certification
- Monitor for trade remedy changes — Section 301, Section 232, and anti-dumping duties are updated periodically. A rate that was correct last quarter may have changed
- Consult CBP resources — for binding classification rulings, CBP's National Commodity Specialist Division provides written determinations
HTS Chapter 70 Classification Guide: Glass and Glassware
Chapter 70 covers glass in all its forms — from unworked cullet, balls, and rods (7001) through sheet and float glass (7003–7005), glass mirrors (7009), glass containers for conveyance or packing (7010), glassware for table or kitchen use (7013), and glass fibers (7019). The chapter excludes certain items that are separately provided for elsewhere, notably glass that is a component of a larger machine (then classified with that machine) and optical elements of Chapter 90. Classification turns on the degree of processing, the intended use, and whether the glass is worked (cut, bent, decorated) beyond simple forming. Drinkware and table glassware are split between lead crystal and other glass in heading 7013.
Common Misclassification Errors
- Classifying glass tumblers and tableware as ceramic (Ch 69) — table glassware is Chapter 70 heading 7013, distinct from ceramic tableware
- Confusing float/sheet glass for construction (7003–7005) with worked, framed, or safety glass articles such as windshields (8708 as vehicle parts) or mirrors (7009)
- Classifying laboratory glassware as ordinary glassware when calibrated lab glass of heading 7017 may have separate subheadings and uses

Importing Under HTS 700521: What Importers Ask
How do I verify the correct HTS classification before importing?
Request a binding ruling from CBP's National Commodity Specialist Division. The ruling is valid for 5 years and is binding on all CBP ports. Alternatively, consult a licensed customs broker for a classification opinion. Misclassification can result in retroactive duties and Section 592 penalties.
Can I get duty-free treatment under an FTA for this product?
Check the Special rate column on this page for FTA preferences. If a preferential rate is listed, verify your product meets the FTA's specific rules of origin. All FTAs require origin certification — USMCA, KORUS, and others have specific documentation requirements.
What documentation is required at the port of entry?
At minimum: commercial invoice, packing list, bill of lading, and CBP Form 7501 (Entry Summary). Depending on the product, additional documentation may include FTA certificate of origin, FDA prior notice, USDA phytosanitary certificate, or TSCA certification. CBP may request the foreign supplier's manufacturing records.
