It is not enough for customs classification.<\/p>\n\n\n\n<p>For U.S. importers, engineers, and sourcing teams, fasteners often fall under HTS heading 7318. But the correct subheading depends on details such as thread type, material, diameter, head style, function, and whether nuts or washers ship with the bolt.<\/p>\n\n\n\n<p>A small wording error can trigger duty issues, customs delays, post-entry corrections, or supplier disputes.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Why Fastener HS Codes Are Easy to Get Wrong<\/h2>\n\n\n\n<p>Fasteners look simple. Classification is not.<\/p>\n\n\n\n<p>A hex bolt, self-tapping screw, wood screw, rivet, washer, and anchor may all sit in the same warehouse bin area. Customs does not treat them as the same article.<\/p>\n\n\n\n<p>The first mistake is classifying by commercial nickname instead of technical identity.<\/p>\n\n\n\n<p>For example, many buyers call any externally threaded fastener a \u201cbolt.\u201d In practice, a self-tapping screw, machine screw, structural bolt, threaded rod, or custom-formed part may require a different classification path.<\/p>\n\n\n\n<p>Before assigning an HS code, compare the product against drawings, standards, and actual use. A supplier\u2019s invoice description should support that logic.<\/p>\n\n\n\n<p>For product reference, buyers can review XZ Fastener\u2019s <a href=\"https:\/\/xzfastener.com\/ru\/home\/products\/\">fastener product range<\/a> and category structure before preparing import documentation.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Common HS Code Mistakes in Fastener Imports<\/h2>\n\n\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><thead><tr><th>Mistake<\/th><th>Real-World Example<\/th><th>Possible Result<\/th><\/tr><\/thead><tbody><tr><td>Using one HS code for all fasteners<\/td><td>Bolts, washers, rivets, and clamps listed together<\/td><td>Incorrect duty and statistical reporting<\/td><\/tr><tr><td>Ignoring material<\/td><td>Stainless steel and carbon steel treated the same<\/td><td>Wrong subheading or duty exposure<\/td><\/tr><tr><td>Mislabeling function<\/td><td>Self-tapping screws declared as general screws<\/td><td>Customs query or entry correction<\/td><\/tr><tr><td>Skipping diameter details<\/td><td>Thread diameter under 6 mm not stated<\/td><td>Broker forced to guess<\/td><\/tr><tr><td>Treating kits too casually<\/td><td>Bolts shipped with nuts and washers<\/td><td>Wrong set or component classification<\/td><\/tr><tr><td>Relying only on supplier invoice text<\/td><td>\u201cHardware parts\u201d used as description<\/td><td>Higher inspection risk<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<h2 class=\"wp-block-heading\">The Details That Actually Matter<\/h2>\n\n\n\n<h3 class=\"wp-block-heading\">Material and Finish<\/h3>\n\n\n\n<p>Material is one of the first classification signals.<\/p>\n\n\n\n<p>Carbon steel, stainless steel, alloy steel, brass, aluminum, and plastic fasteners may not follow the same tariff path. Finish also matters for product identification, even when it does not change the heading.<\/p>\n\n\n\n<p>A zinc-plated carbon steel bolt should not be described only as \u201csilver bolt.\u201d A customs broker needs the base material, not the color.<\/p>\n\n\n\n<p>Use descriptions like:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Carbon steel hex bolt, zinc plated<\/li>\n\n\n\n<li>Stainless steel 316 full-thread screw<\/li>\n\n\n\n<li>Alloy steel socket head cap screw, black oxide<\/li>\n\n\n\n<li>Carbon steel washer, hot-dip galvanized<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">Thread and Function<\/h3>\n\n\n\n<p>Threading often separates one fastener from another.<\/p>\n\n\n\n<p>A self-tapping screw cuts or forms its own mating thread. A machine screw usually needs a pre-threaded hole or nut. A bolt may be used with a nut and may have a different structural role.<\/p>\n\n\n\n<p>This distinction matters in classification and in engineering review.<\/p>\n\n\n\n<p>For drawing-based parts, custom geometry should be documented early. XZ Fastener\u2019s <a href=\"https:\/\/xzfastener.com\/ru\/home\/customized-service\/\">customized service<\/a> page is a useful internal link when discussing non-standard fasteners, special heads, or project-specific samples.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Diameter, Head Style, and Standard<\/h3>\n\n\n\n<p>Fastener standards help remove ambiguity.<\/p>\n\n\n\n<p>DIN, ISO, ASTM, ASME, and SAE references can support a cleaner classification review. They also help the broker understand whether the part is a hex bolt, carriage bolt, socket screw, threaded stud, washer, or rivet.<\/p>\n\n\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><thead><tr><th>Data Point<\/th><th>Why It Helps<\/th><\/tr><\/thead><tbody><tr><td>\u0421\u0442\u0430\u043d\u0434\u0430\u0440\u0442<\/td><td>Identifies product family and intended form<\/td><\/tr><tr><td>Diameter<\/td><td>Supports subheading decisions<\/td><\/tr><tr><td>Length<\/td><td>Helps distinguish fasteners from pins or rods<\/td><\/tr><tr><td>Head style<\/td><td>Separates hex, round, socket, countersunk, and special heads<\/td><\/tr><tr><td>Thread type<\/td><td>Confirms screw, bolt, stud, or self-tapping function<\/td><\/tr><tr><td>Material grade<\/td><td>Supports material declaration and compliance review<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<h2 class=\"wp-block-heading\">A Practical Classification Workflow<\/h2>\n\n\n\n<h3 class=\"wp-block-heading\">Step 1: Separate Products Before Quoting Freight<\/h3>\n\n\n\n<p>Do not group unlike fasteners into one customs line.<\/p>\n\n\n\n<p>Separate by:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Product type<\/li>\n\n\n\n<li>\u041c\u0430\u0442\u0435\u0440\u0438\u0430\u043b<\/li>\n\n\n\n<li>Size range<\/li>\n\n\n\n<li>\u0421\u0442\u0430\u043d\u0434\u0430\u0440\u0442<\/li>\n\n\n\n<li>Finish<\/li>\n\n\n\n<li>Packaging condition<\/li>\n\n\n\n<li>Whether nuts or washers are included<\/li>\n<\/ul>\n\n\n\n<p>This makes the commercial invoice cleaner and reduces broker back-and-forth.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Step 2: Match the Product Name to the Drawing<\/h3>\n\n\n\n<p>The drawing should drive the description.<\/p>\n\n\n\n<p>If the drawing says DIN 933 full-thread hex bolt, do not declare it as \u201cscrew accessories.\u201d If the product is a T-bolt or slot connector, identify it clearly.
