What is Amazon sea freight?

Amazon sea freight is the logistics model that allows sellers to ship their products by sea to Amazon FBA warehouses in the United States using full container load (FCL) or less than container load (LCL) options. It has a much lower unit cost compared to air cargo; therefore, it is the primary choice for heavy and bulky products.

It operates under the FBA (Fulfillment by Amazon) system. This means products must be delivered directly to the warehouses designated by Amazon, complying with the labeling and packaging standards accepted by Amazon. Shipments that do not comply with these standards may be rejected by Amazon, which means serious delays and extra costs.

Sea freight is planned in two main ways: full container (FCL) or partial load (LCL). Small and medium-sized sellers mostly prefer LCL because they only pay for the space they use.

2026 cost table: how much will you pay?

The cost calculation depends on several variables: product weight, volume, loading port, and destination warehouse. The average unit prices for shipping from Turkey to the US by sea for 2026 can be summarized as follows:

• LCL (partial load): Prices starting from approximately 1.5 USD/dm³ (volume weight)

• FCL (full container): Freight charges ranging on average between 2,500 and 4,000 USD for a 20-foot container

• Insurance: Usually 0.3% to 0.5% of the cargo value

• Customs and warehouse expenses: Additional costs between 300 and 700 USD depending on the destination port

Compared to air cargo, LCL sea freight reduces costs by 60% to 80%. For example, a shipment sent for 1,000 USD by air cargo may cost between 200 and 400 USD by sea; of course, this figure varies depending on the product type and weight.

ParkPalet offers a fixed and transparent pricing of 1.5 USD/dm³ for their Amazon sea freight service; this makes budget planning easier.

Transit times: how many days from door to Amazon warehouse?

The biggest disadvantage of sea freight is the duration. The total time for shipping from Turkey to the US by sea consists of several stages:

1. Loading and port preparation in Turkey: 3 to 7 days

2. Sea transit time: Average of 25 to 35 days (for East Coast ports; 20 to 28 days for the West Coast)

3. US customs clearance: 3 to 10 days (depending on product type and customs congestion)

4. Last mile: delivery from port to Amazon warehouse: 2 to 5 days

The total door-to-warehouse time varies between 35 and 55 days on average. Therefore, sellers using sea freight must plan their inventory at least 2 months in advance. Especially for busy periods like Christmas or Prime Day, it is recommended that products set off at least 3 months in advance.

Required documents and customs process

Customs errors are the most common cause of delays. Preparing documents completely directly speeds up the process.

The basic documents are:

• Bill of Lading (B/L): Issued by the carrier; specifies the owner of the product and the destination.

• Commercial Invoice: Includes product description, unit price, total value, and buyer/seller information.

• Packing List: Shows the contents of each box, gross and net weights, and dimensions.

• Certificate of Origin: A document approved by the Chamber of Commerce is required for products originating in Turkey.

• Amazon FBA shipment plan and box labels: Created via Amazon Seller Central; FNSKU and shipment ID labels are mandatory for each box.

• Customs declaration (ISF and Entry Summary): An ISF (Importer Security Filing) notification is made before loading for shipments entering the US.

Some product categories require additional documentation. FCC certificate for electronic products, FDA registration for food supplements, and Safety Data Sheet (SDS) for products containing chemicals are among the main ones. Confirming in advance which category requires which document prevents products from being detained at customs.

Who is it suitable for, and who is it not?

Sea freight is not ideal for every shipment. The following table makes it easier to decide:

| Profile | Is sea freight suitable? |

|---|---|

| Bulky products over 50 kg | Yes |

| Non-seasonal, shelf-stable products | Yes |

| First test shipment, low quantity | Partially (consider LCL) |

| Urgent inventory needs, less than 3 weeks | No |

| Perishable or very short shelf-life products | No |

| High-value, light-weight products | Debatable (insurance cost increases) |

Sellers with regular and predictable sales volumes benefit the most from sea freight. New sellers receiving only a few orders a week might consider testing with air cargo first and then moving to sea freight.

Common mistakes and how to avoid them

Mistakes made at this stage lead to loss of both money and time.

Packaging and labeling errors: Products that do not comply with Amazon's FBA packaging requirements are not accepted into the warehouse. An FNSKU label, barcode, and shipment ID must be present on the outside and inside of every box. Manufacturer barcodes alone are not sufficient.

Incorrect HS code usage: Incorrect classification in the customs tariff results in high customs duties or detention of the product. Verification with a customs broker should be done before the HS code is determined.

Lack of inventory planning: Due to the long transit time of sea freight shipments, being late leads to poor sales performance. When inventory runs out on Amazon, your search rankings drop, and it takes time to recover.

Not getting insurance: Although maritime accidents are rare, shipping without cargo insurance is an unnecessary risk. The cost of insurance, which is a small percentage of the cargo value, is a logical expense when considering the total shipment value.

Frequently asked questions

Is there a minimum shipment quantity for Amazon sea freight?

There is no minimum volume requirement in the LCL option; shipments can be made even in small volumes like 1 cubic meter. However, the unit cost increases at very small volumes, so shipping with a volume of at least 2 cubic meters is more economical.

How much is the sea freight customs duty from Turkey to the US?

Customs duty varies according to the HS code of the product and the tariff rate applicable in the US. As of 2026, rates of 12% to 32% may apply to textile products, and 0% to 3.7% to electronic products. You should confirm the exact rate with your customs broker or with the ParkPalet team via the contact page.

Should I prefer FCL or LCL?

If you have enough goods to fill a 20-foot container, FCL is cheaper. For small and medium-volume shipments, LCL is always more sensible because you only pay for the space you use.

Can shipping be made without complying with Amazon FBA packaging rules?

No, it cannot. Amazon does not accept non-compliant shipments into the warehouse and turns the products back. In this case, both the sea freight shipping fee is wasted and recalling/repackaging costs are added. ParkPalet eliminates this risk by performing this check while still in Turkey.

Should products be insured in sea freight shipping?

There is no legal obligation, but it is highly recommended for your benefit. For a shipment of 10,000 USD, there is an average insurance cost of 30 to 50 USD; this provides the right to full compensation in the event of a potential loss or damage.

Can I track my products in Amazon sea freight?

Yes. With the container number and bill of lading information, the real-time location can be tracked through the carrier company's tracking system. Regular updates are also provided to customers during ParkPalet shipments.

What can I do if my inventory plan at the Amazon warehouse is disrupted in case of a sea freight delay?

In this case, making an temporary inventory replenishment by air cargo for a short period is the most practical solution. To prevent this, set your inventory planning buffer to at least 45 days. ParkPalet's international prep warehouse service also provides flexibility: you can keep products stored in the US before sending them to Amazon.
