Phí vận chuyển khá đắt.

In Vietnamese, you usually do not use a verb like to be before an adjective in sentences like this.

So:

• Phí vận chuyển khá đắt = The shipping fee is quite expensive

Literally, it is more like:

• shipping fee + quite + expensive

This is very normal in Vietnamese.
Adjectives can act like the predicate by themselves.

Compare:

• Món này ngon. = This dish is delicious.
• Trời nóng. = The weather is hot.
• Phí vận chuyển khá đắt. = The shipping fee is quite expensive.

You would only use là in different structures, not here.

Phí means fee, charge, or cost in the sense of money paid for a service.

So:

• phí vận chuyển = shipping fee
• phí dịch vụ = service fee
• học phí = tuition fee

It is not exactly the same as giá:

• giá = price
• phí = fee/charge
• chi phí = expense/cost
• cước = often rate/fare/shipping charge, sometimes more technical or commercial

In this sentence, phí is the natural choice because shipping is treated as a service charge.

Vietnamese noun phrases usually put the main noun first, followed by words that describe or specify it.

Here:

• phí = fee
• vận chuyển = transport/shipping

So phí vận chuyển literally means fee for shipping.

This word order is very common:

• tiền nhà = house rent / money for housing
• phí dịch vụ = service fee
• vé máy bay = airplane ticket

English often puts the describing noun first, but Vietnamese often does the opposite.

Vận chuyển means transport, shipping, or carrying goods from one place to another.

It is a bit broader and more formal than just delivery.

Depending on context:

• phí vận chuyển = shipping fee
• dịch vụ vận chuyển = transport/shipping service
• công ty vận chuyển = shipping/transport company

If you are talking specifically about bringing an order to the customer, people also often say:

• phí giao hàng = delivery fee

So vận chuyển is correct and natural, but giao hàng may sound more everyday in shopping contexts.

Khá here means quite, rather, or fairly.

So:

• khá đắt = quite expensive / rather expensive

It softens the statement a little. It is not as strong as very.

Rough comparison:

• hơi đắt = a bit expensive
• khá đắt = quite/rather expensive
• rất đắt = very expensive

So khá suggests the speaker thinks the shipping fee is noticeably expensive, but not extremely so.

Yes, đắt can describe a fee, price, service, or item that costs a lot.

Examples:

• Cái áo này đắt. = This shirt is expensive.
• Giá này đắt quá. = This price is too expensive.
• Phí dịch vụ đắt. = The service fee is expensive.
• Phí vận chuyển khá đắt. = The shipping fee is quite expensive.

So it is completely natural here.

A rough pronunciation guide:

• Phí ≈ fee but with a rising tone
• vận ≈ something like vuhn with a heavy, broken low tone
• chuyển ≈ roughly chwee-uhn with a dipping-rising tone
• khá ≈ kha with a rising tone
• đắt ≈ duht with a short, sharp tone

A more useful breakdown:

• phí — rising tone
• vận — nặng tone
• chuyển — hỏi tone
• khá — sắc tone
• đắt — sắc tone

If you want to sound natural, pay special attention to the tones, because they matter a lot in Vietnamese.

Yes, it is natural and correct.

Phí vận chuyển khá đắt is a normal way to say that shipping charges are fairly high.

Depending on context, native speakers might also say:

• Phí giao hàng khá đắt.
• Tiền ship khá đắt.
• Cước vận chuyển khá đắt.

These are slightly different in register:

• phí vận chuyển = standard, neutral
• phí giao hàng = common in shopping/delivery contexts
• tiền ship = informal, mixed Vietnamese-English
• cước vận chuyển = more formal/commercial

It can mean either, depending on context.

Vietnamese often leaves out articles like the, a, or plural marking when the meaning is clear.

So Phí vận chuyển khá đắt could mean:

• The shipping fee is quite expensive
• Shipping fees are quite expensive
• Shipping is quite expensive

Context tells you which meaning is intended.

That is very common in Vietnamese.

Yes. You can change khá to change the strength of the statement.

Examples:

• Phí vận chuyển hơi đắt. = The shipping fee is a bit expensive.
• Phí vận chuyển khá đắt. = The shipping fee is quite expensive.
• Phí vận chuyển rất đắt. = The shipping fee is very expensive.
• Phí vận chuyển đắt quá. = The shipping fee is too expensive.

So khá is just one degree word among several.

They are close, but not always identical.

• vận chuyển focuses on transport/shipping
• giao hàng focuses on delivering goods to the customer

In many online shopping situations, they can be used almost the same way:

• phí vận chuyển = shipping fee
• phí giao hàng = delivery fee

But phí vận chuyển can sound a bit broader or more formal, while phí giao hàng often sounds more everyday and customer-facing.

A very common way is to use có ... không:

• Phí vận chuyển có khá đắt không? = Is the shipping fee quite expensive?

More naturally, people often say:

• Phí vận chuyển có đắt không? = Is the shipping fee expensive?
• Phí vận chuyển đắt không? = Is the shipping fee expensive?

If you want to ask Why is the shipping fee so expensive?, you could say:

• Sao phí vận chuyển đắt vậy?
• Tại sao phí vận chuyển lại đắt như vậy?

You usually put không before the adjective:

• Phí vận chuyển không đắt. = The shipping fee is not expensive.

You can also say:

• Phí vận chuyển không khá đắt is grammatically possible, but not very natural.

Normally, if you want to negate the whole idea, you just say:

• Phí vận chuyển không đắt.

If you want a softer meaning:

• Phí vận chuyển không đắt lắm. = The shipping fee is not very expensive.

Yes. Khá can also mean fairly good, decent, or rather well in other contexts.

For example:

• Anh ấy học khá. = He studies fairly well.
• Tình hình khá hơn rồi. = The situation is better now.
• khá nhiều = quite a lot

But in khá đắt, it clearly works as an adverb meaning quite/rather.

So learners should remember that khá is flexible, and its exact meaning depends on what follows it.
