Packaging Tariffs Explained: How They Work and Affect Costs

March 30, 2026

Many B2B businesses importing packaging face a common issue: the same product receives very different quotes from different suppliers. This often leads to confusion and concerns about pricing transparency.

In reality, the difference is not only in product cost. A major factor is how packaging tariffs are applied. Without understanding tariffs, buyers may:

Compare suppliers incorrectly
Misjudge actual costs
Face risks during customs clearance

This article explains how packaging tariffs work and why they affect supplier quotes, focusing purely on the mechanism.

What Are Packaging Tariffs?

Packaging tariffs are import duties applied to packaging products when they enter a specific country. These tariffs are part of a broader customs system designed to regulate trade, protect domestic industries, and generate government revenue.

A common misunderstanding is that tariffs are applied based on simple product labels such as “paper cup” or “plastic container.” In reality, tariffs are determined based on technical classification rules, including:

The primary material (paper, plastic, bio-based material)
The product’s structure (single-layer, coated, laminated)
Its intended use (food contact vs. non-food contact)

Important Facts Buyers Should Know

Not all packaging products are taxed the same way
Tariff rates are not decided by suppliers
Two products with the same name may fall under different tariff categories

This means that understanding tariffs requires understanding classification, not just product descriptions.

How Tariffs Are Actually Determined

HS Code – The Foundation of Tariffs

The basic tariff rate for imported goods is determined by the United States Harmonized Tariff Schedule (HTSUS), published and maintained by the United States International Trade Commission (USITC).

Every product entering a country must be assigned an HS Code. This code determines:

The base import duty rate
Whether additional tariffs apply
What regulations or inspections are required

Even small differences in product characteristics can lead to different HS Codes.

Example

A paper cup without coating may fall under one classification
A paper cup with polyethylene (PE) coating may fall under another

Similarly:

Plastic lids made from polypropylene (PP)
Plastic lids made from polystyrene (PS)

Each may be classified differently

Section 122 Surtax (Latest Update 2026)

Per the White House Proclamation and subsequent enforcement guidance by U.S. Customs and Border Protection (CBP):

Under Section 122, a 10% surtax has been imposed on most imported goods entering the United States, effective from February 24, 2026.

Country of Origin Matters

Another critical factor in determining tariffs is the country of origin.

The same product can be subject to different tariffs depending on where it is manufactured. This is influenced by:

Trade agreements
Political and economic policies
Bilateral or multilateral tariff structures

Example:

Two suppliers offer identical paper cups, but their import tax rates differ based on the country of origin:

Supplier A manufactures in China → subject to a different (often higher) import tariff
Supplier B manufactures in Vietnam → may benefit from a lower or preferential tax rate, depending on trade agreements

Even if the products are technically identical, the applicable tariffs may differ significantly.

Special Tariffs (Section 301, Anti-dumping)

In addition to standard import duties, certain products may be subject to special tariffs.

One well-known example is Section 301 Tariffs. Currently, the Section 301 Tariffs continue to impose an additional 25% duty on the majority of packaging products imported from China. Meanwhile, items classified under List 4A benefit from a lower 7.5% tariff rate. (Source: Office of the United States Trade Representative (USTR))

These tariffs were introduced as part of trade measures targeting specific imports from China.

Important Points

They apply only to specific HS Codes
Not all products from China are affected
Rates may change over time

Other special tariff mechanisms include:

Anti-dumping duties (to prevent unfairly low-priced imports)
Countervailing duties (to offset foreign government subsidies)

Key Insight

Tariff determination is not just about base duty rates. It may include multiple layers of taxation depending on classification and origin.

Understanding HS Code and origin is not always straightforward, especially when small material differences can change classification.

If you’re unsure whether your packaging is being classified correctly, the team at Kimecopak can help verify HS Codes and origin details before you move forward with a supplier.

Common Packaging Categories and How They Are Classified

Understanding how packaging is categorized helps buyers ask better questions and avoid incorrect assumptions.

Paper Packaging

This category includes:

Paper cups
Paper bags
Folding cartons

However, classification depends on several factors:

Whether the product is coated (PE, PLA, wax, etc.)
Whether it is intended for food contact
The thickness and composition of the material

“Paper packaging” is not a single category. Even minor variations in coating or composition can result in different classifications.

Plastic Packaging

Plastic packaging includes:

Lids
Straws
Containers

Classification is based on:

Polymer type (PP, PET, PS, etc.)
Manufacturing process
Intended use

Typical U.S. MFN tariff for plastic tableware under HS 3924 is around 3.1% – 6.5%. Example: PET plastic cups (HS 3924.10) → ~3.4% base duty

Different plastics are treated as different materials in tariff systems. This means that:

Two visually similar products can have different tariff rates
Material specifications must be clearly defined

Compostable / Biodegradable Packaging

This is one of the most misunderstood categories.

Many buyers assume that environmentally friendly packaging automatically benefits from lower tariffs. However:

Tariffs are still based on the primary material
Compostable materials like PLA may still be classified under plastics

Example:

A “compostable” PLA cup → still taxed as plastic (HS 3924)
A “paper cup with PLA lining” → may be classified as composite material, not pure paper

Note: Terms like “compostable” or “biodegradable” are marketing descriptions, not tariff classifications.

Why Two Suppliers Quote Different Landed Costs

When two suppliers offer similar products at different prices, it’s usually not just pricing strategy.

The real reason is often tariffs and how they are added together (tariff stacking).

What Makes Up Landed Cost in 2026

Today, import cost is made up of multiple layers:

Base duty (MFN): ~0–6.5%
Section 301 Tariffs: +25% (China), or +7.5% (List 4A)
Section 122 surtax: +10% (applied to most imports)
Merchandise Processing Fee: $33.58 – $651.50 per shipment

Miss one of these = your cost estimate is wrong

Why Prices Look Different

Even for the same product, suppliers may:

Use different HS Codes
Ship from different countries
Calculate different tariff assumptions

Example:

Supplier A → calls it paper → lower tax
Supplier B → calls it coated material → higher tax

Same product, but different taxes = different final price

Simple Rule for Buyers

To compare quotes correctly, always check:

Same HS Code
Same origin
Same full tax structure (including Section 301 + Section 122 + MPF)

Practical Implications for B2B Buyers

Understanding packaging tariffs is not just a compliance issue, it directly affects how you evaluate suppliers and make purchasing decisions.

What You Should Always Verify

HS Code used for the product
Country of origin
Applicability of special tariffs

What You Should Avoid

Comparing prices without verifying classification
Assuming all “similar” products are treated equally
Relying only on supplier descriptions

Why This Matters

Tariffs are not an external add-on. They are part of the core cost structure behind every quote.

Misunderstanding tariffs leads to:

Poor supplier selection
Unexpected costs
Operational risks

FAQs

1. What is the most important factor in determining packaging tariffs?

The most important factor is the HS Code (Harmonized System Code). It defines how a product is classified and directly determines the applicable duty rates and regulations.

2. Can two identical packaging products have different tariffs?

Yes. Even if products look identical, tariffs can differ due to:

Different HS Code classifications
Different countries of origin
Different interpretations of product structure

3. Do suppliers control or decide tariff rates?

No. Suppliers do not control tariffs. Tariffs are set by government authorities based on classification systems and trade policies.

However, suppliers may influence how a product is classified, which can affect the applied tariff.

4. Are eco-friendly or compostable packaging products taxed less?

Not necessarily.

Terms like “compostable” or “biodegradable” do not determine tariff rates. Products are still classified based on their main material, which may fall under existing plastic or paper categories.

5. What are Section 301 Tariffs and do they apply to all packaging?

These are additional tariffs applied by the U.S. to certain imports from China.

They do not apply to all packaging products. Applicability depends on:

The HS Code
The product category

6. What should I always check before comparing supplier quotes?

You should confirm:

HS Code
Country of origin
Whether any special tariffs apply

Without aligning these factors, price comparisons can be misleading.

7. How can I reduce risk when dealing with packaging tariffs?

You can reduce risk by:

Verifying HS Codes before ordering
Asking suppliers for detailed classification information
Double-checking tariff applicability with a reliable partner

Conclusion

Packaging tariffs are not a minor detail, they are a fundamental part of how import costs are structured.

Many B2B buyers assume that price differences between suppliers come from production cost or margin. In reality, a significant portion of that difference often comes from how products are classified, where they are made, and how tariffs are applied.
