Таможенная стоимость выше объявленной ценности.

Russian often leaves out the verb to be in the present tense.

So:

• Таможенная стоимость выше объявленной ценности.

literally works like:

• The customs value [is] higher than the declared value.

In the present tense, Russian normally does not say есть here. Adding есть would usually sound unnatural in this kind of sentence.

Таможенная стоимость is in the nominative case because it is the subject of the sentence.

Breakdown:

• таможенная = feminine singular nominative adjective
• стоимость = feminine singular nominative noun

They agree with each other in:

• gender: feminine
• number: singular
• case: nominative

So this whole phrase means customs value and functions as the thing being described.

Because after выше in this kind of construction, Russian commonly uses the genitive case for the thing being compared to.

So:

• выше объявленной ценности = higher than the declared value

Here:

• объявленной = feminine singular genitive
• ценности = feminine singular genitive

This is a very common pattern with comparatives:

• выше цены = higher than the price
• ниже уровня = lower than the level
• старше брата = older than the brother

So the sentence structure is:

• X выше Y-genitive = X is higher than Y

Yes. Russian can compare things in two main ways:

1. comparative + genitive
2. comparative + чем

So you can have:

• Таможенная стоимость выше объявленной ценности.
• Таможенная стоимость выше, чем объявленная ценность.

Both mean roughly the same thing.

The version with the genitive is often more compact and formal. The version with чем can feel a bit more explicit, closer to English than.

Yes. Выше is the comparative form corresponding to высокий (high, tall).

So:

• высокий = high
• выше = higher

This is not formed the same way as English more high. It is its own comparative form, like better from good.

In sentences like this, выше acts as the predicate:

• Стоимость выше. = The value is higher.

Yes, it behaves like an adjective.

Объявленной comes from объявленный and means declared. It is a participial adjective derived from the verb объявить / объявлять.

Here it modifies ценности, so it must agree with ценности in:

• gender: feminine
• number: singular
• case: genitive

That is why you get:

• nominative: объявленная ценность
• genitive: объявленной ценности

So the form changes because the noun it describes is in the genitive.

They are related, but not identical.

• стоимость usually means price, cost, or monetary value
• ценность often means value in a broader sense, including worth, importance, or preciousness

In customs and legal contexts, стоимость is very common for financial value. Ценность can also mean declared value depending on context, but it has a broader semantic range.

So a learner may notice that both words can be translated as value, but in Russian they are not exact copies of each other.

Таможенная comes from таможня, meaning customs.

The adjective таможенный / таможенная / таможенное means:

• relating to customs
• customs-related

So:

• таможенная стоимость = customs value
• таможенная пошлина = customs duty
• таможенный контроль = customs control

Here it is feminine singular because it agrees with стоимость, which is feminine.

Because they are feminine nouns:

• стоимость
• ценность

A useful clue is that many Russian nouns ending in -ость are feminine.

Examples:

• скорость = speed
• стоимость = cost/value
• возможность = possibility
• ценность = value/worth

Even though they end in a soft sign ь, they are feminine, not masculine.

Not completely. Russian word order is more flexible than English, because case endings show grammatical relationships.

The neutral order here is:

• Таможенная стоимость выше объявленной ценности.

You might also see different orders for emphasis, but this version is the most straightforward.

For example, moving words around could highlight one part more strongly, but for a learner, the given order is the safest and most natural one to use.

Here is a simple breakdown:

• Таможенная — customs, feminine singular nominative adjective
• стоимость — value / cost, feminine singular nominative noun
• выше — higher, comparative form
• объявленной — declared, feminine singular genitive adjective/participle
• ценности — value / worth, feminine singular genitive noun

So the structure is:

• [subject] + [comparative] + [genitive phrase]

That is why it means:

• The customs value is higher than the declared value.

Good question, because -и endings can belong to different cases in Russian.

Here, you identify it from both form and function:

1. Ценность is a feminine noun ending in -ость
2. Its genitive singular is ценности
3. After выше, Russian commonly uses the genitive
4. Объявленной also matches genitive singular feminine

So the grammar of the whole phrase tells you that объявленной ценности is genitive singular.

Yes, it sounds fairly formal or official, especially because of vocabulary like:

• таможенная стоимость
• объявленной ценности

This feels like the kind of language you might see in:

• customs documents
• shipping forms
• legal or administrative writing

It is not especially conversational everyday speech, though it is perfectly normal Russian in the right context.
